DETAILED DESCRIPTION

[0041] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application.

[0044] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] With the development of science and technology and the improvement of users' living standards, refrigerators are playing an increasingly important role in production and life. Usually, a heat preservation layer is set on the door of the refrigerator to prevent external heat from entering the refrigerator and reduce the loss of cold air inside the refrigerator, thereby maintaining a stable temperature inside the refrigerator and improving the refrigerator's refrigeration performance. At the same time, the development of vehicle technology and the growth of user demand have made the application of car refrigerators in vehicles more and more popular. As part of vehicle modification or upgrade, car refrigerators not only improve the functionality of the vehicle, but also increase the driving pleasure and comfort.

[0046] However, the size of a car refrigerator is limited due to its limited installation space on the vehicle. In order to meet the requirements of the car refrigerator locking mechanism, it is usually necessary to sacrifice the space of the door insulation layer, which has an adverse effect on the refrigerator's refrigeration performance. Reducing the size of the locking mechanism will help reduce the door space occupied by the locking mechanism and improve the refrigeration performance of the car refrigerator. In addition, compared with the method of controlling the opening and closing of the door through a solenoid valve in some vehicles, it needs to rely on the power-on status of the vehicle, which limits the use scenarios of the car refrigerator, and the reliability of this structure is low.

[0047] Based on the above reasons, the embodiment of the present application provides a locking mechanism, which can be installed on the door of a vehicle refrigerator to reduce the space occupied on the door and improve the refrigeration performance of the refrigerator. It should be noted that the embodiment of the present application only takes the locking mechanism set on the vehicle refrigerator as an example for explanation. In actual application, the locking mechanism can also be used in any flip-open door structure.

[0048] The locking mechanism provided in the embodiment of the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] In the embodiment of the present application, the first direction x, the second direction y, and the third direction z intersect each other. Optionally, the first direction x, the second direction y, and the third direction z are perpendicular to each other.

[0050] like Figures 1 to 4As shown, the locking mechanism may include: a first sliding component 20, a second sliding component 30 and a hand assembly 10, the first sliding component 20 is suitable for moving along a first direction x, the second sliding component 30 is suitable for being linked with the first sliding component 20, and the second sliding component 30 is suitable for moving along a second direction y; the hand assembly 10 includes a hand 11, the hand 11 is movably cooperated with the first sliding component 20, the movement of the hand 11 can drive the first sliding component 20 to move along the first direction x, and the movement of the first sliding component 20 along the first direction x can drive the second sliding component 30 to move along the second direction y, so that the locking mechanism can be switched between a locked state and an unlocked state.

[0051] It can be understood that the user can easily drive the first sliding component 20 to move along the first direction x by simply rotating the buckle 11 or pressing the buckle, and then link the second sliding component 30 to move along the second direction y to complete the locking or unlocking action, which greatly improves the convenience and efficiency of opening and closing the locking mechanism.

[0052] Optionally, in an embodiment of the present application, one of the first sliding component 20 and the second sliding component 30 is provided with a guide pin 211 extending along the third direction z, and the other of the first sliding component 20 and the second sliding component 30 is provided with a guide bevel 311 cooperating with the guide pin 211, and the guide pin 211 at least partially passes through the guide bevel 311 and is slidably connected in the guide bevel 311 to drive the second sliding component 30 to move along the second direction y.

[0053] Furthermore, the guide slot 311 may be a through slot extending along the third direction z, and the guide pin 211 may pass through the guide slot 311. Figure 1 As shown, the inclined direction of the guiding inclined slot 311 here is any direction between the first direction x and the second direction y.

[0054] In the embodiment of the present application, the guide pin 211 and the guide groove 311 are precisely matched to ensure the stability and consistency of the two during movement. This design not only reduces the friction and resistance during movement, but also improves the transmission efficiency and ensures the smooth execution of the locking and unlocking actions.

[0055] Further, the first sliding assembly 20 is provided with a guide pin 211 extending along the third direction z, and the second sliding assembly 30 is provided with a guide bevel 311 cooperating with the guide pin 211. The guide bevel 311 is arranged obliquely and has a first end 3111 and a second end 3112 opposite to each other in the extending direction. In the locked state of the locking mechanism, in the second direction y, the first end 3111 is closer to the first sliding assembly 20 than the second end 3112, and in the first direction x, the first end 3111 is closer to the buckle 11 than the second end 3112. That is, the first end 3111 of the guide bevel 311 is arranged close to the buckle 11 and the first sliding assembly 20, and the second end 3112 of the guide bevel 311 is arranged away from the buckle 11 and the first sliding assembly 20, so as to ensure that when the buckle 11 is in a stationary state, the locking mechanism is in a locked state.

[0056] Optionally, the first sliding assembly 20 and the second sliding assembly 30 are arranged along the second direction y, wherein the second sliding assembly 30 moves along the second direction y close to the first sliding assembly 20 to switch the locking mechanism to the unlocked state, and the second sliding assembly 30 moves along the second direction y away from the first sliding assembly 20 to switch the locking mechanism to the locked state. In this way, it is convenient for the second sliding assembly 30 arranged on the box door to cooperate with the door stop structure arranged on the box body described later.

[0057] Optionally, the number of the second sliding components 30 is two, specifically, as Figures 1 to 3 As shown, the two second sliding components 30 are respectively arranged on both sides of the first sliding component 20 along the second direction y. It should be noted that in the embodiment of the present application, the two second sliding components 30 are both slidably connected to the bracket component 40 along the second direction y, and the movement directions of the two second sliding components 30 are opposite. When the two second sliding components 30 move toward each other, the door can be unlocked, and when the two second sliding components 30 move away from each other, the door can be locked.

[0058] In actual applications, the symmetrical layout and reverse movement design of the two second sliding components 30 ensure that, in the locked state, both sides of the door are subjected to balanced and stable locking forces at the same time, which helps to reduce the jamming or imbalance that may be caused by the movement of a single sliding component; in addition, this double locking mechanism effectively improves the stability and safety of the door locking, and can improve the reliability of the door closing even when the vehicle is driving on an uneven road or encounters external force impact.

[0059] It should be noted that, in the embodiment of the present application, one set of second sliding components 30 is used as an example for explanation. When two sets of second sliding components 30 are provided, the number of structures for cooperating with the second sliding components 30 is increased to two sets accordingly. Among them, the first sliding member 21 can be kept as one, and the structure provided on the first sliding member 21 can be symmetrically provided on both sides of the first sliding member 21 along the second direction y.

[0060] Alternatively, if Figure 1 As shown, the locking mechanism includes a bracket assembly 40, the buckle handle 11 is rotatably connected to the bracket assembly 40, an installation cavity is provided inside the bracket assembly 40, and the first sliding assembly 20 and the second sliding assembly 30 are both provided in the installation cavity of the bracket assembly 40.

[0061] The bracket assembly 40 is used to install various matching structures and plays a supporting and protective role for the matching structures. The bracket assembly 40 also serves as a connecting bridge between the locking mechanism and the box door and is used to be installed on the box door. Specifically, the bracket assembly 40 is provided with a plurality of mounting holes and is installed on the box door through fasteners. In the embodiment of the present application, the first sliding assembly 20 and the second sliding assembly 30 are both arranged in the mounting cavity of the bracket assembly 40, which also makes the appearance of the box door more concise and beautiful. It should be noted that in the embodiment of the present application, the thickness direction of the box door is the first direction x.

[0062] Optionally, the first sliding component 20 and the second sliding component 30 are arranged in the installation cavity along the second direction y and are linked together. The first sliding component 20 moves along the first direction x to drive the second sliding component 30 to move along the second direction y. When the second sliding component 30 moves to be at least partially exposed outside the installation cavity, the locking mechanism can be put into a locked state to lock the box door; when the second sliding component 30 moves to be accommodated in the installation cavity, the locking mechanism can be put into an unlocked state to unlock the box door.

[0063] Specifically, the handle 11 is connected to the bracket assembly 40, the bracket assembly 40 is connected to the door, and the handle 11 is at least partially exposed from the bracket assembly 40, so that the user can pull the handle 11 from the outside of the refrigerator. In the embodiment of the present application, the handle 11 is rotatably connected to the bracket assembly 40. When the handle 11 rotates, the handle 11 can press down the first sliding assembly 20, so that the first sliding assembly 20 is close to the second sliding assembly 30. At this time, the second sliding assembly 30 moves toward the installation cavity. When the second sliding assembly 30 moves to be accommodated in the installation cavity, the locking structure can unlock the door; and when the second sliding assembly 30 moves in the opposite direction to be at least partially exposed from the installation cavity, the locking mechanism can lock the door.

[0064] Furthermore, in an embodiment of the present application, the bracket assembly 40 includes a first bracket 41 and a second bracket 42, and the first bracket 41 and the second bracket 42 are arranged along a first direction x and enclose a mounting cavity, wherein the hand-clasp assembly 10 is rotatably connected to a side of the first bracket 41 facing away from the second bracket 42, and the first sliding assembly 20 and the second sliding assembly 30 are movably connected to the second bracket 42.

[0065] Specifically, an opening is provided on the first bracket 41, at which the first sliding assembly 20 and the buckle 11 are opposite to each other along the first direction x, so that the buckle 11 can abut against and cooperate with the first sliding assembly 20. The independent design of the first bracket 41 and the second bracket 42 also facilitates the assembly of the internal components of the locking mechanism.

[0066] In the embodiment of the present application, the first sliding component 20 includes a first sliding member 21 and a first elastic member 22. The first sliding member 21 is suitable for abutting and cooperating with the buckle assembly 10 and bearing the downward pressure of the buckle 11 to approach the second bracket 42 along the first direction x; the first elastic member 22 is used to provide a restoring force for the first sliding member 21 to move away from the second bracket 42.

[0067] It should be noted that when the user rotates the buckle 11, the buckle 11 can press down the first sliding member 21. At this time, the first elastic member 22 is in an energy storage state. When the user releases the buckle 11, the external force disappears, and the buckle 11 can quickly and smoothly return to its original position under the drive of the first elastic member 22, ready for the next unlocking operation. For example, in the embodiment of the present application, the first elastic member 22 is a compression spring, wherein the first elastic member 22 can also use other elastic structures, such as metal springs, which is not specifically limited in the present application.

[0068] Furthermore, the first elastic member 22 is elastically connected between the first sliding member 21 and the second bracket 42 along the first direction x, so that the arrangement of the first elastic member 22 is facilitated and a restoring force can be more reliably provided for the first sliding member 21 .

[0069] Optionally, a mating portion 212 is provided on one side of the first sliding member 21 close to the first bracket 41, the mating portion 212 protrudes from the first sliding member 21 along the first direction x toward the first bracket 41, and the mating portion 212 is suitable for slidingly abutting with the buckle 11. The mating portion 212 includes a mating surface 2121 close to the first bracket 41, and in the embodiment of the present application, the mating surface 2121 is a curved surface.

[0070] It should be noted that when the installation cavity space is limited, by providing a mating portion 212 protruding from the surface of the first sliding member 21, the size of the first sliding member 21 along the first direction x can be reduced, thereby reducing the weight of the entire locking mechanism, and providing more layout space for other structures inside the installation cavity, thereby improving layout flexibility.

[0071] In addition, since the mating surface 2121 is a curved surface, the contact between the buckle handle 11 and the first sliding member 21 is smoother during the rotation and downward pressing process, reducing the jamming feeling that may be caused by right-angle or acute-angle contact. This smooth operating experience not only improves the user's comfort, but also reduces mechanical wear caused by improper operation, thereby extending the service life of the locking mechanism.

[0072] Optionally, the first sliding member 21 is provided with a guide hole 213, and the second bracket 42 is provided with a guide shaft 421. The guide shaft 421 extends along the first direction x toward the first bracket 41 and passes through the guide hole 213. In actual application, when the first sliding member 21 approaches or moves away from the second bracket 42, since the first sliding member 21 is sleeved on the guide shaft 421 through the guide hole 213, the shaking and deviation of the first sliding member 21 moving along the first direction x are reduced, ensuring that the first sliding member 21 can accurately and smoothly approach or move away from the second sliding component 30, thereby improving the accuracy and reliability of the locking and unlocking actions.

[0073] Optionally, the first sliding assembly 20 further includes a limiting member 23 , which includes a connecting portion 231 and a limiting portion 232 , wherein the connecting portion 231 is connected to the second bracket 42 , so that the first sliding member 21 is movably connected between the limiting portion 232 and the second bracket 42 .

[0074] In practical applications, the limit member 23 can be a limit screw having a head and a rod. The rod of the limit screw is connected to the second bracket 42, and the head can limit the movement of the first sliding member 21 to ensure that the first sliding member 21 moves within a preset range of movement.

[0075] Further, the guide shaft 421 is a hollow structure, and at least part of the connecting portion 231 is connected inside the guide shaft 421. It is understandable that when the guide shaft 421 is set as a hollow structure, the connection between the stopper 23 and the second bracket 42 reuses the structure of the guide shaft 421, simplifying the internal structure of the locking structure.

[0076] In the embodiment of the present application, the second sliding assembly 30 includes a second sliding member 31 and a second elastic member 32. The second sliding member 31 is slidably connected to the second bracket 42 along the second direction y to lock or unlock the box door. The second elastic member 32 is used to provide a restoring force for the second sliding member 31 away from the installation cavity.

[0077] It should be noted that, in the embodiment of the present application, the second elastic member 32 is arranged to provide the second sliding member 31 with a restoring force along the second direction y away from the installation cavity. Specifically, after the door is unlocked, once the external force such as the downward pressure of the buckle 11 disappears, the second elastic member 32 can automatically push the second sliding member 31 to reset, so that it is away from the installation cavity, so that the locking mechanism is restored to the locked state. In addition, during the unlocking process, when the first sliding component 20 approaches the second sliding component 30, the elastic force of the second elastic member 32 needs to be overcome in order for the second sliding member 31 to move into the installation cavity, so that the unlocking operation requires a certain amount of force, thereby avoiding accidental unlocking due to accidental touch or slight external force.

[0078] Furthermore, the second elastic member 32 is elastically connected between the second sliding member 31 and the second bracket 42 along the second direction y.

[0079] Further, the second sliding member 31 is provided with a first limiting rib 312, and the second bracket 42 is provided with a second limiting rib 422. The first limiting rib 312 and the second limiting rib 422 are arranged opposite to each other along the second direction y and have limiting protrusions, and the second elastic member 32 can be a compression spring, and both ends are sleeved on the limiting protrusions.

[0080] The first bracket 41, the second bracket 42, the first limiting rib 312, and the second limiting rib 422 define a mounting position for mounting the second elastic member 32, so that the second elastic member 32 is precisely connected between the first limiting rib 312 and the second limiting rib 422 along the second direction y, thereby preventing the second elastic member 32 from being misplaced or falling off during operation. In practical applications, when the second sliding member 31 moves toward the inside of the mounting cavity, the first limiting rib 312 compresses the second elastic member 32 so that the second elastic member 32 stores energy, thereby providing a power basis for the automatic reset of the second sliding member 31.

[0081] In the embodiment of the present application, the buckle 11 includes a first side and a second side arranged in opposition along a first direction x, the first side is arranged close to the first sliding component 20 and is provided with a sliding portion 111 extending toward the first sliding component 20, and the second side is exposed to the external environment.

[0082] Specifically, the sliding portion 111 is an oblique pin extending toward the mating portion 212 on the first sliding member 21. During the rotation of the buckle 11, the oblique pin can slide on the mating surface 2121 and maintain abutment with the mating surface 2121, thereby ensuring the mating effect between the buckle 11 and the first sliding component 20.

[0083] Furthermore, the buckle assembly 10 also includes an axle pin 12, a torsion spring 13, and a locking piece 14, wherein the axle pin 12 passes through the first bracket 41 and the buckle 11, the locking piece 14 is locked to the end of the axle pin 12, the torsion spring 13 passes through the axle pin 12, and the two torsion arms of the torsion spring 13 are respectively in contact with the buckle 11 and the first bracket 41.

[0084] Among them, the locking member 14 can be a retaining spring, and the shaft pin 12 is provided with an annular retaining groove, and the retaining spring can be clamped in the retaining groove to ensure the rotational connection between the shaft pin 12, the buckle 11, and the first bracket 41. In the embodiment of the present application, the buckle 11 is rotationally connected to the first bracket 41 through the shaft pin 12, and combined with the use of the torsion spring 13, the buckle 11 is provided with an automatic reset function. After the user operates the buckle 11 to unlock, when the user releases the buckle 11, the torsion spring 13 can automatically drive the buckle 11 to return to the initial position.

[0085] Optionally, at least one of the buckle handle 11 and the first bracket 41 is provided with a slot, and the slot is suitable for accommodating the torsion arm.

[0086] It should be noted that, since the axle pin 12 has a certain length, when the length of the torsion spring 13 is smaller than the length of the axle pin 12, the tight combination of the torsion arm of the torsion spring 13 and the card slot effectively prevents the torsion spring 13 from loosening or shifting during long-term use, thereby ensuring the stability and reliability of the buckle assembly 10.

[0087] In the embodiment of the present application, the buckle 11 is provided with a first clamping slot 112, the first bracket 41 is provided with a second clamping slot 411, and the two torsion arms are respectively clamped in the first clamping slot 112 and the second clamping slot 411. It can be understood that when the two torsion arms of the torsion spring 13 are both limited in the clamping spring, a more effective limiting effect can be provided for the torsion spring 13.

[0088] In the embodiment of the present application, the buckle 11 is further provided with a first limiting step 113, and the first bracket 41 is further provided with a second limiting step 412. The first limiting step 113 and the second limiting step 412 are arranged along the rotation path of the buckle 11. When the buckle 11 is pulled, the buckle 11 rotates around the shaft pin 12, and the torsion spring 13 squeezes and stores energy. When the buckle 11 rotates until the first limiting step 113 abuts against the second limiting step 412, the rotation stops; when the buckle 11 is released, the torsion spring 13 is restored, and under the action of the torsion spring 13, the buckle 11 rotates in the opposite direction to restore the initial state.

[0089] In summary, the locking mechanism provided in the embodiment of the present application has at least the following advantages:

[0090] In the embodiment of the present application, the first sliding assembly can be driven to move in the first direction through the cooperation with the buckle assembly; further, when the first sliding assembly moves in the first direction, the second sliding assembly can be driven to move in the second direction, so that the locking mechanism can switch between the locked state of locking the box door and the unlocked state of unlocking the box door. The embodiment of the present application can achieve the locking and unlocking of the box door through the cooperation of a simple mechanical structure, with fewer internal parts, simple cooperation relationship, high reliability, and reduced space occupied on the box door; at the same time, the box door locking mechanism provided by the embodiment of the present application has strong versatility and can be applied to a variety of box door structures.

[0091] The present application also discloses a vehicle-mounted refrigerator, comprising a cabinet, a cabinet door, and the locking mechanism as described above, wherein the locking mechanism is arranged on the cabinet door, and the cabinet is provided with a door stop structure, which is used to cooperate with the second sliding assembly 30 to achieve locking of the cabinet door.

[0092] Specifically, the door stop structure can be a lock groove. When the second sliding component 30 moves away from the installation cavity, the second sliding component 30 can move to extend into the lock groove to lock the door. When the second sliding component 30 is out of the lock groove, the door is unlocked.

[0093] Optionally, the thickness direction of the door is the first direction x.

[0094] The present application also discloses a vehicle, comprising the locking mechanism or the vehicle refrigerator as described above.
