In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0050] The gravity self-locking assembly 13 of the embodiment of the utility model can be applied to the refrigeration device 1, and the refrigeration device 1 can be a refrigerator, a freezer, a display cabinet, a wine cabinet, etc., which is not specifically limited here. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the gravity self-locking assembly 13 of the embodiment of the utility model includes: a guide seat 132 and a guide seat 131.

[0051] The guide seat 132 is provided with a guide surface 1321, and the guide seat 131 is provided with a sliding surface 1311 adapted to the guide surface 1321, and the sliding surface 1311 can move relative to the guide surface 1321. In the case where the guide seat 131 and the guide seat 132 are matched, the guide seat 131 is located above the guide seat 132, and the guide surface 1321 is provided on the guide seat 132 on the side facing the guide seat 131. In other words, the guide surface 1321 is provided on the top surface of the guide seat 132. Exemplarily, the guide surface 1321 is provided along the edge position of the top surface of the guide seat 132. The sliding surface 1311 is provided on the guide seat 131 on the side facing the guide seat 132. In other words, the sliding surface 1311 is provided on the bottom surface of the guide seat 131. Exemplarily, the sliding surface 1311 is provided along the edge position of the bottom surface of the guide seat 131.

[0052] Among them, the gravity self-locking component 13 has a closed state and an open state, and can switch between the closed state and the open state. When the gravity self-locking component 13 moves from the closed state to the open state, the sliding surface 1311 sequentially rises, falls and translates on the guide surface 1321; when the gravity self-locking component 13 moves from the open state to the closed state, the sliding surface 1311 sequentially translates, rises and falls on the guide surface 1321.

[0053] In an embodiment of the utility model, under the action of external force, the sliding surface 1311 can rise on the guide surface 1321, and then descend and translate under the action of gravity. In addition, during the translation of the sliding surface 1311 on the guide surface 1321, it can ensure that the guide seat 131 maintains a certain angle relative to the guide seat 132, thereby completing the switching from the closed state to the open state; under the action of external force, the sliding surface 1311 can translate and rise on the guide surface 1321, and then descend under the action of gravity, thereby completing the switching from the open state to the closed state. During the opening and closing processes, gravity can be used to assist in opening and closing, which can save more effort.

[0054] In addition, in the related art, the door mechanism generally does not have any device for blocking the door in a specific position. For example, if a user opens the door of the refrigerator to load goods into the main cabinet, the user may have to hold the door in a specific position and load the goods in the main cabinet at the same time. This may be troublesome for the user and also cause a lot of time consumption when loading the refrigerator.

[0055] In order to solve the above problems, in an optional embodiment, when the gravity self-locking component 13 moves from a closed state to an open state, the sliding surface 1311 sequentially rises, translates once, descends, and translates twice on the guide surface 1321; when the gravity self-locking component 13 moves from an open state to a closed state, the sliding surface 1311 sequentially translates once, rises, translates twice, and descends on the guide surface 1321.

[0056] Specifically, under the action of external force, the sliding surface 1311 can rise on the guide surface 1321, and then the sliding surface 1311 can translate once on the guide surface 1321. At this time, the guide seat 131 maintains a certain angle relative to the guide seat 132. Afterwards, under the action of external force again, the sliding surface 1311 ends one translation on the guide surface 1321, and then descends and translates a second time under the action of gravity. In addition, during the second translation of the sliding surface 1311 on the guide surface 1321, it can ensure that the guide seat 131 maintains a certain angle relative to the guide seat 132, thereby completing the switching from the closed state to the open state; under the action of external force, the sliding surface 1311 can translate once, rise and translate a second time on the guide surface 1321, and then descend under the action of gravity.

[0057] like Figure 3 , Figure 4 as well as Figure 5 As shown, the guide surface 1321 includes a first inclined surface 13211, a first plane 13212, a second inclined surface 13213 and a second plane 13214 connected in sequence, and the sliding surface 1311 includes a third inclined surface 13111 and a third plane 13112 connected in sequence.

[0058] Exemplarily, the first inclined surface 13211, the first plane 13212, the second inclined surface 13213 and the second plane 13214 are sequentially arranged along the edge position of the top surface of the guide seat 132, the first inclined surface 13211 and the first plane 13212 are extended along the first direction, the second plane 13214 is extended along the second direction, the first direction and the second direction are perpendicular, the second inclined surface 13213 connects the first plane 13212 and the second plane 13214, in other words, the second inclined surface 13213 is bent. In addition, the third inclined surface 13111 and the third plane 13112 are sequentially arranged along the edge position of the bottom surface of the guide seat 131, and the third inclined surface 13111 and the third plane 13112 are extended in the same direction.

[0059] When the gravity self-locking component 13 moves from a closed state to an open state, the third inclined surface 13111 moves relative to the first inclined surface 13211, the third plane 13112 moves relative to the first plane 13212, the edge where the third inclined surface 13111 and the third plane 13112 intersects moves relative to the second inclined surface 13213, and the third plane 13112 moves relative to the second plane 13214.

[0060] When the gravity self-locking component 13 moves from an open state to a closed state, the third plane 13112 moves relative to the second plane 13214, the edge where the third inclined surface 13111 and the third plane 13112 intersect moves relative to the second inclined surface 13213, the third plane 13112 moves relative to the first plane 13212, and the third inclined surface 13111 moves relative to the first inclined surface 13211.

[0061] like Figure 6 , Figure 7 and Figure 8As shown, under the action of external force, the third inclined surface 13111 can rise on the first inclined surface 13211, and then the third plane 13112 can perform a translation on the first plane 13212. At this time, the guide seat 131 maintains a certain angle relative to the guide seat 132. Afterwards, under the action of external force again, the third plane 13112 ends a translation on the first plane 13212, and then under the action of gravity, the edge where the third inclined surface 13111 and the third plane 13112 intersects drops on the second inclined surface 13213, and then the third plane 13112 is translated twice on the second plane 13214. It is particularly worth noting that the edge where the third inclined surface 13111 and the third plane 13112 intersect is in line contact during the movement on the second inclined surface 13213, which can reduce the contact area and thus reduce the door opening resistance. Moreover, during the second translation of the third plane 13112 on the second plane 13214, the third plane 13112 and the second plane 13214 are in surface contact, which can increase the force area and improve the stability in the open state, thereby completing the switching from the closed state to the open state.

[0062] Under the action of external force, the third plane 13112 can translate once on the second plane 13214, and then the edge where the third inclined surface 13111 and the third plane 13112 intersect each other rises on the second inclined surface 13213, and then the third plane 13112 translates twice on the first plane 13212. After the second translation, finally, under the action of gravity, the third inclined surface 13111 descends on the first inclined surface 13211. It should be pointed out in particular that the edge where the third inclined surface 13111 and the third plane 13112 intersect each other is in line contact during the movement on the second inclined surface 13213, which can reduce the contact area and thus reduce the closing resistance, and, in the process where the third inclined surface 13111 descends on the first inclined surface 13211, through the cooperation between the first inclined surface 13211 and the third inclined surface 13111, it can be ensured that the third inclined surface 13111 maintains a downward trend on the first inclined surface 13211, thereby improving the closing effect, thereby completing the switching from the closed state to the open state.

[0063] In an optional embodiment, when the third plane 13112 moves relative to the first plane 13212 , the rotation angle of the guide seat 131 relative to the guide seat 132 is 5 to 45°.

[0064] Exemplarily, under the action of external force, the third inclined surface 13111 can rise on the first inclined surface 13211, and then the third plane 13112 can translate once on the first plane 13212. At this time, the rotation angle of the guide seat 131 relative to the guide seat 132 is 45°, that is, the guide seat 131 can hover at 45° relative to the guide seat 132.

[0065] Alternatively, under the action of external force, the third plane 13112 can translate once on the second plane 13214, and then the edge where the third inclined surface 13111 and the third plane 13112 intersect rises on the second inclined surface 13213, and then the third plane 13112 translates a second time on the first plane 13212, and the guide seat 131 can hover at 45° relative to the guide seat 132.

[0066] In an optional embodiment, when the third plane 13112 moves relative to the first plane 13212 , the upward displacement of the guide seat 131 relative to the guide seat 132 is 2 to 10 mm.

[0067] Exemplarily, under the action of external force, the third inclined surface 13111 can rise on the first inclined surface 13211, and then the third plane 13112 can translate once on the first plane 13212. At this time, the guide seat 131 can hover at 45° relative to the guide seat 132, and the rising displacement of the guide seat 131 relative to the guide seat 132 is 5 mm.

[0068] In addition, under the action of external force again, the third plane 13112 ends a translation on the first plane 13212, and then under the action of gravity, the edge where the third inclined surface 13111 and the third plane 13112 intersects drops on the second inclined surface 13213, and then the third plane 13112 translates a second time on the second plane 13214. At this time, the guide seat 131 can hover at 110° relative to the guide seat 132, and the rising displacement of the guide seat 131 relative to the guide seat 132 is 2 mm.

[0069] In an optional embodiment, the slope of the first inclined surface 13211 is greater than or equal to 10°. Exemplarily, the slope of the first inclined surface 13211 is 15°.

[0070] It should be noted that, under the action of external force, the third plane 13112 can translate once on the second plane 13214, and then the edge where the third inclined surface 13111 and the third plane 13112 intersect rises on the second inclined surface 13213, and then the third plane 13112 translates twice on the first plane 13212. After the second translation, finally, under the action of gravity, the third inclined surface 13111 descends on the first inclined surface 13211. It should be particularly pointed out that the slope of the first inclined surface 13211 is 15°, which can enhance the gravity-assisted descending effect of the third inclined surface 13111 on the first inclined surface 13211, and can enhance the downward trend of the third inclined surface 13111 on the first inclined surface 13211, thereby enhancing the closing effect.

[0071] In practical applications, the slope of the second inclined surface 13213 is smaller than the slope of the first inclined surface 13211 .

[0072] Exemplarily, the slope of the first inclined surface 13211 is 15°, and the slope of the second inclined surface 13213 is 13°. At this time, under the action of external force, the third plane 13112 can be translated once on the second plane 13214, and then the edge where the third inclined surface 13111 and the third plane 13112 intersect rises on the second inclined surface 13213. That is to say, the greater the slope of the second inclined surface 13213, the greater the external force required for the edge where the third inclined surface 13111 and the third plane 13112 intersect to rise on the second inclined surface 13213. The slope of the second inclined surface 13213 is 13°, which can reduce the door closing resistance to a certain extent.

[0073] In an optional embodiment, the slope of the second inclined surface 13213 is greater than 15° or less than 15°.

[0074] Specifically, when the inclination angle of the second inclined surface 13213 is greater than 15°, the component force of the gravity of the guide seat 131 on the second inclined surface 13213 can be greater than the friction force, thereby realizing automatic door opening. That is to say, under the action of external force, the third inclined surface 13111 can rise on the first inclined surface 13211, and then the third plane 13112 can perform a translation on the first plane 13212. Thereafter, under the action of external force again, the third plane 13112 ends a translation on the first plane 13212, and then under the action of gravity, the edge where the third inclined surface 13111 and the third plane 13112 intersect automatically descends on the second inclined surface 13213 without the action of external force.

[0075] When the inclination angle of the second inclined surface 13213 is less than 15°, the component force of the gravity of the guide seat 131 on the second inclined surface 13213 can be smaller than the friction force, so that the guide seat 131 can be suspended relative to the guide seat 132, and the door opening process is assisted, and the resistance is not too large during the door closing process. That is to say, under the action of external force, the third inclined surface 13111 can rise on the first inclined surface 13211, and then the third plane 13112 can perform a translation on the first plane 13212, and then, under the action of external force again, the third plane 13112 ends a translation on the first plane 13212, and then, the edge where the third inclined surface 13111 and the third plane 13112 intersect is suspended on the second inclined surface 13213. Furthermore, under the action of external force, the third plane 13112 can translate once on the second plane 13214 , and then the edge where the third inclined surface 13111 and the third plane 13112 intersects hovers on the second inclined surface 13213 .

[0076] In practical applications, the widths of the first inclined surface 13211 , the second inclined surface 13213 , the third inclined surface 13111 , the first plane 13212 , the second plane 13214 , and the third plane 13112 are less than or equal to 20 mm.

[0077] Exemplarily, the width of the first inclined surface 13211, the second inclined surface 13213, the third inclined surface 13111, the first plane 13212, the second plane 13214 and the third plane 13112 is 15 mm, wherein the width of the first inclined surface 13211, the second inclined surface 13213, the third inclined surface 13111, the first plane 13212, the second plane 13214 and the third plane 13112 can be equal or different, depending on the actual working conditions, and no specific limitation is made here.

[0078] In the embodiment of the utility model, the width of the first inclined surface 13211, the second inclined surface 13213, the third inclined surface 13111, the first plane 13212, the second plane 13214 and the third plane 13112 is less than or equal to 20 mm, which can reduce the contact area between the sliding surface 1311 and the guide surface 1321 while ensuring the stable movement of the sliding surface 1311 on the guide surface 1321, thereby reducing the resistance and facilitating closing and opening.

[0079] like Figure 3 and Figure 4 As shown, the guide seat 131 has a guide groove 1313 on one side of the sliding surface 1311 , and the guide seat 132 has a guide shaft 1322 on one side of the guide surface 1321 . The guide shaft 1322 extends into the guide groove 1313 .

[0080] Exemplarily, two guide shafts 1322 are provided on one side of the guide seat 132 provided with the guide surface 1321, and the two guide shafts 1322 are sequentially provided along the third direction, and the third direction is parallel to the first direction. In addition, two guide grooves 1313 are also concavely provided on one side of the guide seat 131 provided with the sliding surface 1311, and both guide grooves 1313 are arc-shaped guide grooves 1313. Among them, the two guide shafts 1322 correspond to the two arc-shaped guide grooves 1313 one by one.

[0081] Specifically, when the gravity self-locking assembly 13 moves from the closed state to the open state, the guide shaft 1322 moves from the first end of the guide groove 1313 to the second end of the guide groove 1313, and when the gravity self-locking assembly 13 moves from the open state to the closed state, the guide shaft 1322 moves from the second end of the guide groove 1313 to the first end of the guide groove 1313. It can be understood that the cooperation between the guide shaft 1322 and the guide groove 1313 can ensure that the sliding surface 1311 always moves along the guide surface 1321.

[0082] In addition, if Figure 1 and Figure 2 As shown, the refrigeration device 1 of the embodiment of the utility model includes: a door body 12, an equipment body 11 and the above-mentioned gravity self-locking assembly 13, the door body 12 is provided with a guide seat 131, the equipment body 11 is provided with a guide seat 132, and the door body 12 is connected to the equipment body 11 through the guide seat 131 and the guide seat 132.

[0083] The refrigeration device 1 has a closed state and an open state. When the door body 12 is away from the device body 11, the refrigeration device 1 is in the open state. When the door body 12 is close to the device body 11, the refrigeration device 1 is in the closed state.

[0084] Under the action of external force, the third inclined surface 13111 can rise on the first inclined surface 13211, and then the third plane 13112 can translate once on the first plane 13212. At this time, the door body 12 maintains a certain angle relative to the equipment body 11. Afterwards, under the action of external force again, the third plane 13112 ends a translation on the first plane 13212, and then under the action of gravity, the edge where the third inclined surface 13111 and the third plane 13112 intersects drops on the second inclined surface 13213. Then, the third plane 13112 translates twice on the second plane 13214, thereby completing the switching of the refrigeration equipment 1 from a closed state to an open state.

[0085] Under the action of external force, the third plane 13112 can be translated once on the second plane 13214, and then the edge where the third inclined plane 13111 and the third plane 13112 intersect rises on the second inclined plane 13213, and then the third plane 13112 is translated twice on the first plane 13212. After the second translation is completed, finally, under the action of gravity, the third inclined plane 13111 descends on the first inclined plane 13211, thereby completing the switching of the refrigeration device 1 from the closed state to the open state. Among them, the distances of the first translation and the second translation can be set according to the actual working conditions, and are not specifically limited here.

[0086] In practical applications, such as Figure 2 As shown, the gravity self-locking assembly 13 also includes a mounting base 134, which is disposed at the bottom of the equipment body 11, and at least part of the mounting base 134 corresponds to the corner of the door body 12, the guide seat 131 is disposed at the corner of the door body 12, and the guide seat 132 is disposed on the mounting base 134.

[0087] Exemplarily, two-thirds of the mounting base 134 corresponds to the bottom of the device body 11, and one-third of the mounting base 134 corresponds to the bottom of the door body 12. The guide seat 131 can be embedded at a right angle to the door body 12. When the guide seat 131 is embedded at a right angle to the door body 12, the outer periphery of the guide seat 131 can be flush with the outer periphery of the door body 12. The guide seat 132 is provided on the side of the mounting base 134 facing the bottom of the door body 12. In addition, in order to facilitate the movement of the refrigeration device 1, casters can be provided on the side of the mounting base 134 away from the bottom of the device body 11.

[0088] In practical applications, such as Figure 2 As shown, the gravity self-locking assembly 13 also includes a door opening stopper 133 , which is disposed on the door body 12 , and the mounting base 134 is provided with a limiting portion 1341 , which is located on the moving path of the door opening stopper 133 .

[0089] Among them, when the gravity self-locking component 13 moves from a closed state to an open state, the door opening stop 133 is close to the limiting portion 1341, and the door opening stop 133 can cooperate with the limiting portion 1341 to stop. When the gravity self-locking component 13 moves from an open state to a closed state, the door opening stop 133 is away from the limiting portion 1341.

[0090] It should be noted that, when the door body 12 is provided with a cabinet panel, the door opening stopper 133 can be sandwiched between the door body 12 and the cabinet panel.

[0091] In actual application, when the gravity self-locking assembly 13 moves from a closed state to an open state and the sliding surface 1311 translates on the guide surface 1321 , the door opening stopper 133 can cooperate with the stopper of the limiting portion 1341 .

[0092] Specifically, under the action of external force, the third inclined surface 13111 can rise on the first inclined surface 13211, and then the third plane 13112 can perform a translation on the first plane 13212. At this time, the door body 12 maintains a certain angle relative to the equipment body 11. Afterwards, under the action of external force again, the third plane 13112 ends a translation on the first plane 13212, and then under the action of gravity, the edge where the third inclined surface 13111 and the third plane 13112 intersects the second inclined surface 13213. Then, the third plane 13112 performs a second translation on the second plane 13214. During the second translation process, the door opening stopper 133 can cooperate with the limit portion 1341 to stop, thereby completing the switching of the refrigeration equipment 1 from a closed state to an open state.

[0093] like Figure 2 , Figure 3 and Figure 5As shown, an avoidance groove 1312 is provided on the outer periphery of the guide seat 131 , a door opening stopper 133 is provided on the door body 12 and is located in the avoidance groove 1312 , and a limiting groove 1323 is provided on the side of the guide seat 132 away from the equipment body 11 .

[0094] The guide seat 131 is provided with an avoidance groove 1312 corresponding to the outer side of the door body 12, and the avoidance groove 1312 is adapted to the door opening stopper 133. In addition, the fastener is sequentially passed through the door opening stopper 133, the guide seat 131 and the door body 12 to connect the door opening stopper 133 and the door body 12. It should be noted that the inner side of the door body 12 refers to the side of the door body 12 facing the device body 11, and the inner side of the door body 12 and the outer side of the door body 12 are arranged opposite to each other.

[0095] When the gravity self-locking assembly 13 moves from the open state to the closed state and the sliding surface 1311 descends on the guide surface 1321 , the door opening stopper 133 can cooperate with the limiting groove 1323 to stop.

[0096] Specifically, under the action of external force, the third plane 13112 can translate once on the second plane 13214, and the door opening stop 133 moves away from the limiting portion 1341. Subsequently, the edge where the third inclined surface 13111 and the third plane 13112 intersect rises on the second inclined surface 13213. After that, the third plane 13112 translates twice on the first plane 13212. After the second translation, finally, under the action of gravity, the third inclined surface 13111 descends on the first inclined surface 13211. In the process of the third inclined surface 13111 descending on the first inclined surface 13211, the door opening stop 133 can cooperate with the limiting groove 1323 to stop, thereby completing the switching of the refrigeration equipment 1 from the closed state to the open state.

[0097] In an optional embodiment, the refrigeration device 1 further includes an ejection assembly, which is used to open or close the door body 12 .

[0098] The non-contact sensing controller is connected to the ejection assembly, and when the non-contact sensing controller is triggered, the ejection assembly is controlled to open the door body 12. The non-contact sensing controller refers to a sensing controller that can be triggered without user contact. For example, when a human body enters the sensing area of ​​the non-contact sensing controller or the non-contact sensing controller is triggered by sound, the non-contact sensing controller controls the ejection mechanism to open the door body 12.

[0099] That is to say, the user does not need to touch the refrigerator during the door opening process, but only needs to trigger the non-contact sensing controller. This can greatly facilitate the user to open the door body 12. For example, when the user has items in both hands and it is inconvenient to open the door body 12, the non-contact sensing controller can be triggered by sound or body, and for the elderly and children, the door body 12 can be opened without any effort.

[0100] The non-contact sensing controller may include a non-contact sensor and a controller. The non-contact sensor may generate a door opening signal when triggered. The controller may be connected to the ejection assembly and the non-contact sensor respectively to control the ejection assembly to open the door body 12 after receiving the door opening signal. Thus, the non-contact sensing controller may control the ejection assembly to open the door body 12 when triggered. The controller may be a single chip microcomputer.

[0101] The non-contact sensor can be arranged on the device body 11. Since the user needs to trigger the non-contact sensor when opening the door, by arranging the non-contact sensor on the device body 11, it is possible to prevent the door body 12 from being damaged when the user opens the door. In other words, if the non-contact sensor is arranged on the door body 12, the user is easily damaged by the opened door body 12 in order to trigger the non-contact sensor.

[0102] In practical applications, the non-contact sensor may be an infrared sensor. When a human body enters the outer sensing area of ​​the non-contact sensor, the non-contact sensor is triggered, thereby triggering the non-contact sensing controller without contact. The non-contact sensor may also be a sound sensor. Similarly, the non-contact sensing controller may be triggered without contact.

[0103] The ejection assembly can be arranged on the device body 11 and the ejection assembly can include a shell, an electromagnetic coil and an ejection core. The shell can have a receiving cavity and a central through hole can be provided on the front end surface of the shell. The electromagnetic coil can be arranged in the receiving cavity. The ejection core can be movably arranged in the receiving cavity and the ejection core can pass through the electromagnetic coil. When the electromagnetic coil is energized, the ejection core can move forward and extend out of the central through hole to open the door body 12. When the non-contact induction controller is triggered, the electromagnetic coil is energized, and the ejection core moves forward to open the door body 12, thereby realizing that the ejection core opens the door body 12 under the control of the non-contact induction controller. Among them, a central through hole can also be provided on the rear end surface of the shell, so that the length of the shell in the front-to-back direction can be reduced, thereby reducing the consumables of the shell to reduce the production cost. The ejection assembly can also include an elastic member, which can be connected to the ejection core to reset the ejection core when the electromagnetic coil is powered off. Specifically, after the ejection assembly opens the door body 12, the electromagnetic coil is de-energized, and the ejection core moves backward under the action of the elastic member, so that the ejection core can be automatically reset to avoid the door body 12 from colliding with the ejection core when the door body 12 is closed.

[0104] Under the action of the ejection assembly, the third inclined surface 13111 can rise on the first inclined surface 13211, and then the third plane 13112 can perform a translation on the first plane 13212. At this time, the door body 12 maintains a certain angle relative to the equipment body 11. Afterwards, under the action of the ejection assembly again, the third plane 13112 ends a translation on the first plane 13212, and then under the action of gravity, the edge where the third inclined surface 13111 and the third plane 13112 intersect on the second inclined surface 13213, and then the third plane 13112 performs a second translation on the second plane 13214, thereby completing the switching of the refrigeration equipment 1 from the closed state to the open state.
