Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] At present, in order to meet the ice demand of users, refrigerators are usually equipped with ice makers. The ice maker is usually installed on the first door body to maximize the storage space in the refrigerator body. A receiving cavity with an opening is formed on the first door body, and the receiving cavity is used to receive the ice maker. The refrigerator also includes a second door body, which is hinged to the first door body to open or close the receiving cavity. The second door body is filled with an insulation layer to improve the cooling effect in the receiving cavity. A locking mechanism is also provided between the second door body and the first door body.

[0003] In the related art, the locking mechanism usually includes a lock body and a rib. The lock body is inserted into the second door body, and a rotating handle is provided at one end of the lock body facing away from the accommodating cavity, and a hook is provided at one end of the lock body facing the accommodating cavity. The rib is provided on the first door body. When locking the first door body and the second door body, the rotating handle is rotated, and the rotating handle can drive the hook to rotate, and the hook is clamped on the rib, thereby locking the first door body and the second door body.

[0004] However, the locking mechanism in the related art reduces the thermal insulation performance of the second door body and increases the condensation risk of the second door body. Utility Model Content

[0005] The embodiment of the present application provides a refrigerator, which can solve the technical problem in the related art that the locking mechanism reduces the thermal insulation performance of the second door body and increases the condensation risk of the second door body.

[0006] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0007] A box body, which is constructed with a refrigeration compartment;

[0008] A first door body, which is hinged to the box body and is used to open or close the refrigeration compartment, and a first accommodating cavity and a second accommodating cavity are configured on a side of the first door body facing the refrigeration compartment when the first door body is closed;

[0009] an ice maker, which is disposed in the first accommodating chamber and is used for making ice;

[0010] a second door body, which is hinged to the first door body and is used to open or close the first accommodating cavity;

[0011] A locking mechanism, comprising a locking hook, a locking cam and a stopper, wherein the locking hook is connected to a side of the second door body facing the second accommodating cavity when the second door body is closed; the locking cam is rotatably disposed in the second accommodating cavity and is configured to selectively lock the locking hook; the stopper is swingably disposed in the second accommodating cavity and is configured to selectively lock the locking cam;

[0012] Wherein, when the locking mechanism is in a locked state, the second door body is closed, the locking hook extends into the second accommodating cavity to push the locking cam to rotate and is locked by the locking cam, and the stop member locks the locking cam; when the locking mechanism is in an unlocked state, the second door body is pushed in the direction of closing the second door body, the locking hook continues to push the locking cam to rotate, and the stop member releases the lock of the locking cam; when the second door body is opened, the locking hook pulls the locking cam to rotate in the opposite direction, so that the locking cam releases the lock of the locking hook.

[0013] The refrigerator of the embodiment of the present application realizes the locking and unlocking functions of the locking mechanism through the mutual cooperation between the locking hook and the locking cam, and the locking cam and the stopper, so as to facilitate closing and opening the second door body. And by arranging the locking cam and the stopper in the second accommodating cavity of the first door body, and arranging the locking hook on the side facing the second accommodating cavity when the second door body is closed, the main components of the locking mechanism can be arranged on the first door body, and the space of the second door body occupied by the locking mechanism can be reduced as much as possible, so that the interior of the second door body can be completely filled with the insulation layer, reducing or eliminating the negative impact of the locking mechanism on the insulation performance of the second door body, enhancing the insulation performance of the second door body, and reducing the condensation risk of the second door body. In addition, when the second door body is closed, the second door body can cover the locking hook, the locking cam and the stopper, so as to achieve the effect of hiding the locking mechanism, improve the appearance of the second door body, and enhance the user experience.

[0014] In some embodiments of the present application, the lock hook extends in a direction perpendicular to the second door body, and the lock hook is provided with a locking through hole perpendicular to its extension direction; the locking cam is provided with a pushing portion and a locking portion, and along the radial direction of the locking cam, the length of the pushing portion is greater than the length of the locking portion, and a second accommodating recessed portion is formed between the pushing portion and the locking portion; wherein, when the locking mechanism is in a locked state, the lock hook extends into the second accommodating cavity, and the end of the lock hook passes over the locking portion and enters the second accommodating recessed portion, and abuts against the pushing portion, and pushes the pushing portion to rotate, so that the locking portion is inserted into the locking through hole, so that the lock hook is locked by the locking cam.

[0015] In this arrangement, since the length of the pushing portion is greater than the length of the locking portion, when the lock hook is extended into the second accommodating cavity, the lock hook will not interfere with the locking portion, and the end of the lock hook can pass over the locking portion to contact the pushing portion and push the pushing portion, so that the locking cam rotates in the direction α. ​​During the rotation of the locking cam, the locking portion can be inserted into the locking through hole of the lock hook to lock the lock hook, so that the locking mechanism is in a locked state.

[0016] In some embodiments of the present application, the locking mechanism further includes a first elastic member, which is connected to the locking cam to apply a first restoring force to the locking cam, and the first restoring force is in the same direction as the reverse rotation direction of the locking cam.

[0017] In this way, when the locking mechanism is in the locked state, the locking cam rotates under the push of the lock hook, the locking cam causes the first elastic member to deform, and the first elastic member generates a first restoring force opposite to the rotation direction of the locking cam, and the first restoring force acts on the locking cam. Due to the locking action of the stopper, the locking cam does not rotate. When the locking mechanism is switched to the unlocked state, the stopper releases the rotation of the locking cam. The locking cam rotates in the opposite direction under the action of the first restoring force generated by the first elastic member, so that the locking cam can automatically reset to the unlocked position, so as to switch the locking mechanism to the locked state again.

[0018] In some embodiments of the present application, a locking protrusion is provided on the side of the locking cam facing away from the locking hook; along the rotation direction of the locking cam when the locking mechanism is switched to the locking state, a guide surface is provided on the front side of the locking protrusion, and a locking recess is provided on the rear side of the locking protrusion, and the guide surface extends to the locking recess at an angle relative to the axial direction of the locking cam; the stop member is swingably provided on the side of the locking cam facing away from the second door body, and a stop protrusion is provided on the top of the stop member; when the locking mechanism is in the locking state and the locking hook pushes the locking cam to rotate, the guide surface pushes the stop protrusion so that the stop protrusion slides along the guide surface into the locking recess.

[0019] With such arrangement, when the locking mechanism switches from the unlocked state to the locked state, the guide surface of the locking protrusion abuts against the stop protrusion of the stopper. The stopper can swing. The locking cam rotates under the push of the lock hook. The guide surface can push the stop protrusion so that the stop protrusion slides along the guide surface toward the locking recess until the stop protrusion enters the locking recess, thereby locking the locking cam.

[0020] In some embodiments of the present application, a first limiting portion is formed between a portion of the guide surface close to the locking recess and the locking recess, and the first limiting portion is used to limit the stop protrusion located in the locking recess.

[0021] With such arrangement, when the locking mechanism is in a locked state, the stop protrusion is located in the locking recess, and the first limiting portion can limit the stop protrusion to prevent the movable protrusion from escaping from the locking recess, thereby improving the reliability of the locking state of the locking mechanism.

[0022] In some embodiments of the present application, an unlocking channel is provided between the locking protrusion and the end face of the locking cam, and the unlocking channel extends from the locking recess to a portion of the guide surface away from the locking recess; when the locking mechanism is in an unlocked state and the locking hook continues to push the locking cam to rotate, the stop protrusion leaves the locking recess and slides along the unlocking channel to the guide surface.

[0023] With such a configuration, the locking mechanism can be unlocked by pushing the second door body and the lock hook again without setting up an additional unlocking structure, which simplifies the mechanical structure of the locking mechanism, reduces the size of the unlocking mechanism, and improves the assembly convenience of the unlocking mechanism.

[0024] In some embodiments of the present application, a second limiting portion is formed between the unlocking channel and the locking recess, and the second limiting portion is used to limit the stopping protrusion located in the locking recess.

[0025] In this way, when the locking mechanism is in a locked state, the stop protrusion is located in the locking recess, and the second limiting portion can limit the stop protrusion to prevent the movable protrusion from escaping from the locking recess and entering the unlocking channel, thereby improving the reliability of the locking state of the locking mechanism.

[0026] In some embodiments of the present application, the locking mechanism also includes a second elastic member, which connects the side wall of the second accommodating cavity and the stop member, and applies a second restoring force to the stop member, and the direction of the second restoring force is opposite to the swinging direction of the stop member when the locking mechanism is switched to a locked state.

[0027] With such a configuration, when the locking mechanism switches the locking state, the stop protrusion slides along the guide surface toward the locking recess, and the stopper swings. The stopper pulls the second elastic member, causing the second elastic member to deform, and the second elastic member generates a second restoring force opposite to the swinging direction. When the stop protrusion slides along the guide surface to approach the locking recess, the second restoring force can pull the stopper, causing the stopper to swing in the opposite direction, thereby causing the stop protrusion to enter the locking recess, so that the stopper can lock the locking cam. In addition, when the locking mechanism switches from the locking state to the unlocking state, the locking cam continues to rotate under the push of the lock hook, and the stop protrusion can leave the locking recess and enter the unlocking channel under the action of the second restoring force, so that the locking mechanism can be automatically unlocked.

[0028] In some embodiments of the present application, the locking mechanism also includes a mounting bracket, which is connected to the second accommodating cavity and is provided with a second connecting protrusion; the stop member is provided with a third connecting recess, and the third connecting recess is hung on the second connecting protrusion.

[0029] In this arrangement, the stop member and the mounting bracket are connected via the second connecting protrusion and the third connecting recess that are hooked to each other. During the swinging of the stop member, the third connecting recess will not restrict the second connecting protrusion, thereby increasing the swinging range of the stop member.

[0030] In a second aspect, an embodiment of the present application provides a refrigerator, comprising:

[0031] A box body, which is constructed with a refrigeration compartment;

[0032] A first door body, which is hinged to the box body and is used to open or close the refrigeration compartment; when the first door body is closed, a first accommodating cavity and a second accommodating cavity are configured on a side facing the refrigeration compartment;

[0033] an ice maker, at least partially disposed in the first accommodating chamber, for making ice;

[0034] a second door body, which is hinged to the first door body and is used to open or close the first accommodating cavity;

[0035] A locking mechanism includes a locking hook and a locking assembly, wherein the locking hook is connected to a side of the second door body facing the second accommodating cavity when the second door body is closed; the locking assembly is disposed in the second accommodating cavity, and the locking assembly is configured to lock the locking hook when the locking hook is inserted into a first position in the second accommodating cavity, and to unlock the locking hook when the locking hook is inserted into a second position deeper than the first position.

[0036] The refrigerator of the embodiment of the present application, by setting the lock hook on the second door body and setting the lock assembly on the first door body, can make the main parts of the lock mechanism be set on the first door body, and minimize the space of the second door body occupied by the lock mechanism, so that the interior of the second door body can be completely filled with the insulation layer, reducing or eliminating the negative impact of the lock mechanism on the insulation performance of the second door body, enhancing the insulation performance of the second door body, and reducing the condensation risk of the second door body. In addition, when the second door body is closed, the second door body can shield the lock hook and the lock assembly, so as to achieve the effect of hiding the lock mechanism, improve the appearance of the second door body, and enhance the user experience.

[0088] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0089] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and common meanings.

[0090] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0091] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

Thus, features defined with "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0093] 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.

[0094] As described in the background technology, the refrigerator in the related art is provided with a locking mechanism, which has the technical problem that the locking mechanism reduces the thermal insulation performance of the second door body and increases the risk of condensation on the second door body. The inventor has found that the reason is that the lock body of the locking mechanism is installed on the second door body, occupying the space of the second door body, so that the interior of the second door body cannot be completely filled with the thermal insulation layer, thereby reducing the thermal insulation performance of the second door body. Due to the reduction in the thermal insulation performance of the second door body, the cooling capacity of the refrigerator will cause the temperature of the refrigeration door body to decrease, so that the water vapor in the refrigerator body condenses on the refrigeration door body with a lower temperature to form condensation, which increases the risk of condensation on the second door body.

[0095] In view of this, an embodiment of the present application provides a refrigerator, which is provided with a locking mechanism, and the locking mechanism includes a locking hook and a locking assembly. By setting the locking hook on the second door body and setting the locking assembly on the first door body, the main components of the locking mechanism can be set on the first door body, thereby minimizing the space of the second door body occupied by the locking mechanism, reducing or eliminating the negative impact of the locking mechanism on the thermal insulation performance of the second door body, enhancing the thermal insulation performance of the second door body, and reducing the condensation risk of the second door body.

[0096] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0097] refer to Figure 1 The refrigerator of the embodiment of the present application includes a box body 100 and a first door body 200. The box body 100 is configured with a refrigeration compartment, and the refrigeration compartment is used to store food waiting for refrigeration. The first door body 200 is hinged to the box body 100, for example Figure 2 As shown, the first door body 200 and the cabinet body 100 can be hinged via a first hinge 110 to open or close the refrigeration compartment.

[0098] And refer to Figure 3 and Figure 4 , a first accommodating cavity 221 and a second accommodating cavity may be configured on the side of the first door body 200 facing the refrigerating compartment when the first door body 200 is closed. Exemplarily, the first door body 200 may include a door shell 210 and a door liner 220. The door liner 220 is arranged opposite to the door shell 210 and connected to the door shell 210. The first accommodating cavity 221 and the second accommodating cavity may be formed on the side of the door liner 220 facing away from the door shell 210.

[0099] The refrigerator of the embodiment of the present application may further include an ice maker 300 for making ice. The ice maker 300 may be disposed in the first accommodating chamber 221 to minimize the volume of the refrigerating chamber occupied by the ice maker 300, thereby maximizing the storage space in the box 100. It is understood that other components besides the ice maker 300 may also be disposed in the first accommodating chamber 221, which will not be described in detail in the embodiment of the present application.

[0100] The refrigerator of the embodiment of the present application may further include a second door body 400, which is hinged to the first door body 200. For example, the second door body 400 and the first door body 200 may be hinged via a second hinge 410 to open or close the first accommodating chamber 221, so as to facilitate maintenance and repair of the ice maker 300 located in the first accommodating chamber 221. Exemplarily, the second door body 400 may be filled with an insulation layer (not shown in the drawings) to improve the insulation performance of the second door body 400. A sealing member 420 may also be provided on one side of the second door body 400 facing the first accommodating chamber 221. When the second door body 400 is closed, the sealing member 420 can seal the second door body 400 and the first door body 200, thereby improving the sealing performance of the first accommodating chamber 221 and improving the refrigeration effect of the ice maker 300.

[0101] The refrigerator of the embodiment of the present application further includes a locking mechanism 500, which may include a lock hook 510 and a locking assembly 520. The lock hook 510 is connected to a side of the second door body 400 facing the second accommodating cavity when the second door body 400 is closed. The locking assembly 520 is disposed in the second accommodating cavity. The locking assembly 520 is configured to lock the lock hook 510 when the lock hook 510 is inserted into a first position in the second accommodating cavity, and to release the lock of the lock hook 510 when the lock hook 510 is inserted into a second position deeper than the first position. The locking mechanism 500 has a locked state and an unlocked state. When the locking mechanism 500 is in the locked state, the lock hook 510 is inserted into the first position in the second accommodating cavity, and the locking assembly 520 locks the lock hook 510, so that the second door body 400 is in a closed state. When the locking mechanism 500 is in the unlocked state, the lock hook 510 is inserted into the second accommodating cavity to a second position deeper than the first position, and the locking assembly 520 releases the lock on the lock hook 510, so that the second door body 400 can be opened to facilitate maintenance and inspection of components such as the ice maker 300 in the first accommodating cavity 221.

[0102] The refrigerator of the embodiment of the present application, by setting the lock hook 510 on the second door body 400 and setting the lock assembly 520 on the first door body 200, can make the main parts of the lock mechanism 500 be set on the first door body 200, and reduce the space of the second door body 400 occupied by the lock mechanism 500 as much as possible, so that the interior of the second door body 400 can be completely filled with the insulation layer, reduce or eliminate the negative impact of the lock mechanism 500 on the insulation performance of the second door body 400, enhance the insulation performance of the second door body 400, and reduce the risk of condensation of the second door body 400. In addition, when the second door body 400 is closed, the second door body 400 can cover the lock hook 510 and the lock assembly 520, so as to achieve the effect of hiding the lock mechanism 500, improve the appearance of the second door body 400, and enhance the user experience.

[0103] The lock hook 510 is connected to the side of the second door body 400 facing the second receiving cavity. Figure 5 The lock hook 510 may be a rectangular parallelepiped structure. The lock hook 510 may extend in a direction perpendicular to the second door body 400. The lock hook 510 may be provided with a locking through hole 511 perpendicular to its extension direction. The locking through hole 511 is used to cooperate with the locking assembly 520 to achieve locking and unlocking of the locking mechanism 500.

[0104] The locking assembly 520 is disposed in the second accommodation cavity of the first door body 200. Figure 6 and Figure 7 The locking assembly 520 may include a locking cam 530 and a stopper 540. The locking cam 530 is rotatably disposed in the second accommodating cavity and is configured to selectively lock the locking hook 510. The stopper 540 is swingably disposed in the second accommodating cavity and is configured to selectively lock the locking cam 530. Figure 8 and Fig. 9 When the locking mechanism 500 is in the locked state, the second door body 400 is closed, the lock hook 510 extends into the second accommodating cavity to push the locking cam 530 to rotate in the direction α, and the lock hook 510 is locked by the locking cam 530, and the stopper 540 locks the locking cam 530. Fig.10 and Fig.11 When the locking mechanism 500 is in the unlocked state, the second door body 400 is pushed in the direction of closing the second door body 400, and the lock hook 510 continues to push the locking cam 530 to rotate in the direction α, and the stopper 540 releases the lock on the locking cam 530. Fig.12 and Fig.13 , open the second door body 400, the lock hook 510 pulls the lock cam 530 to rotate in the opposite direction, that is, the lock cam 530 rotates in the direction β, so that the lock cam 530 releases the lock on the lock hook 510.

[0105] The refrigerator of the embodiment of the present application realizes the locking and unlocking functions of the locking mechanism 500 through the mutual cooperation between the locking hook 510 and the locking cam 530 and the locking cam 530 and the stopper 540, so as to facilitate closing and opening the second door body 400. And by arranging the locking cam 530 and the stopper 540 in the second accommodating cavity of the first door body 200, and arranging the locking hook 510 on the side facing the second accommodating cavity when the second door body 400 is closed, the main components of the locking mechanism 500 can be arranged on the first door body 200, and the space of the second door body 400 occupied by the locking mechanism 500 can be reduced as much as possible, so that the interior of the second door body 400 can be completely filled with the insulation layer, reducing or eliminating the negative impact of the locking mechanism 500 on the insulation performance of the second door body 400, enhancing the insulation performance of the second door body 400, and reducing the risk of condensation of the second door body 400. In addition, when the second door body 400 is closed, the second door body 400 can cover the lock hook 510, the locking cam 530 and the stopper 540, thereby achieving the effect of hiding the locking mechanism 500, improving the appearance of the second door body 400, and enhancing the user experience.

[0106] The locking cam 530 and the stopper 540 are both installed in the second accommodating cavity of the refrigeration door body. Figure 3 As shown, the side of the door liner 220 facing away from the door housing 210 may be provided with an open first accommodating recess 222 at its edge. The first door body 200 may also include a cover member 230, Fig.14 and Fig.15 The cover member 230 may include a first cover plate 231 and a second cover plate 232 that are perpendicular to each other. The first cover plate 231 may cover a portion of the opening of the first accommodating recessed portion 222 and is opposite to the locking hook 510. The second cover plate 232 may cover another portion of the opening of the first accommodating recessed portion 222. The first cover plate 231 and the second cover plate 232 and the first accommodating recessed portion 222 are surrounded by a second accommodating cavity.

[0107] The first cover plate 231 may be connected to the first door body 200. For example, the first cover plate 231 may be provided with a first connection hole 233. Figure 3 As shown, the side wall of the first accommodating recess 222 may be provided with a first connecting portion 223. The first connecting portion 223 is opposite to the first connecting hole 233. The connecting bolt may be inserted into the first connecting hole 233 and connected to the first connecting portion 223 to connect the first cover plate 231 and the first connecting portion 223, thereby connecting the first cover plate 231 to the first door body 200. Exemplarily, the first cover plate 231 may also be provided with a locking hole 234, and the locking hook 510 may be inserted into the locking hole 234 to lock with the locking assembly 520 located in the second accommodating cavity.

[0108] The locking assembly 520 is installed in the second accommodating cavity. For example, the locking assembly 520 may further include a mounting bracket 550, the mounting bracket 550 may be connected to the first cover plate 231, and the locking assembly 520 may be installed on the mounting bracket 550. Fig.16 The mounting bracket 550 may include two mounting arms 551 and a second connecting portion 552. The two mounting arms 551 are arranged opposite to each other and spaced apart, and the two mounting arms 551 are both provided with a second connecting hole 553. Fig.15 As shown, two third connection parts 235 may be provided on one side of the first cover plate 231 located in the second accommodating cavity, and the two third connection parts 235 are respectively provided corresponding to the two mounting arms 551. Each third connection part 235 is provided with a connection column 236, and the connection column 236 is inserted into the second connection hole 553 on the corresponding mounting arm 551. The second connection part 552 is located between the two mounting arms 551 and connected to the two mounting arms 551. The second connection part 552 is provided with a third connection hole 554. Fig.15 As shown, a fourth connection portion 237 may be provided on one side of the first cover plate 231 located in the second accommodation cavity, and the fourth connection portion 237 is opposite to the third connection hole 554. A connection bolt may be passed through the third connection hole 554 and connected to the fourth connection portion 237 to connect the second connection portion 552 to the fourth connection portion 237, thereby connecting the mounting bracket 550 to the first cover plate 231.

[0109] The locking cam 530 is rotatably disposed in the second accommodating cavity. Exemplarily, the locking cam 530 may be located between the two mounting arms 551, and the locking cam 530 may be provided with a connecting through hole 531. Both mounting arms 551 are provided with a fourth connecting hole 555, and the fourth connecting hole 555 is opposite to the connecting through hole 531. The locking assembly 520 may further include a rotating shaft 560, the rotating shaft 560 is passed through the connecting through hole 531, and the two ends of the rotating shaft 560 are respectively inserted into the fourth connecting holes 555 of the two mounting arms 551. The locking cam 530 is rotatably connected to the two mounting arms 551 through the rotating shaft 560.

[0110] refer to Fig.16 and Fig.17 The locking cam 530 may be provided with a pushing portion 532 and a locking portion 533. In the radial direction of the locking cam 530, the length of the pushing portion 532 may be greater than the length of the locking portion 533, and a second accommodating recess 534 is formed between the pushing portion 532 and the locking portion 533. Figure 8As shown, when the locking mechanism 500 is in the locked state, the lock hook 510 can extend into the second accommodating cavity, and the end of the lock hook 510 can pass over the locking portion 533 and enter the second accommodating recessed portion 534, and abut against the pushing portion 532, and push the pushing portion 532 to rotate, so that the locking portion 533 is inserted into the locking through hole 511, so that the lock hook 510 is locked by the locking cam 530. Since the length of the pushing portion 532 is greater than the length of the locking portion 533, when the lock hook 510 extends into the second accommodating cavity, the lock hook 510 will not interfere with the locking portion 533, and the end of the lock hook 510 can pass over the locking portion 533 and contact the pushing portion 532, and push the pushing portion 532, so that the locking cam 530 rotates in the direction α. ​​During the rotation of the locking cam 530, the locking portion 533 can be inserted into the locking through hole 511 of the lock hook 510 to lock the lock hook 510, so that the locking mechanism 500 is in the locked state.

[0111] For example, Figure 7 As shown, the locking mechanism 500 may further include a first elastic member 570, and the first elastic member 570 may be connected to the locking cam 530. For example, the locking cam 530 may be provided with a third accommodating recess 535, and the bottom of the third accommodating recess 535 is provided with a connecting through hole 531. The first elastic member 570 may be a torsion spring. The torsion spring is located in the third accommodating recess 535 and is sleeved on the rotating shaft 560. The first end of the coil spring is fixedly connected to the side wall or the bottom of the third accommodating recess 535. The other end of the coil spring extends out of the third accommodating recess 535 and abuts against the second connecting portion 552 of the mounting bracket 550. The first elastic member 570 may apply a first restoring force to the locking cam 530, and the first restoring force is in the same direction as the reverse rotation of the locking cam 530. That is, the first elastic member 570 provides the locking cam 530 with a first restoring force toward the direction β.

[0112] like Figure 8 As shown in FIG. 5 , when the locking mechanism 500 is in a locked state, the locking cam 530 rotates in the direction α under the push of the locking hook 510, and the locking cam 530 causes the first elastic member 570 to deform, and the first elastic member 570 generates a first restoring force opposite to the direction α, and the first restoring force acts on the locking cam 530. Due to the locking effect of the stopper 540, the locking cam 530 does not rotate. Fig.12 When the locking mechanism 500 is switched to the unlocked state, the stopper 540 releases the rotation of the locking cam 530. Under the action of the first restoring force generated by the first elastic member 570, the locking cam 530 rotates in the direction β opposite to the direction α, so that the locking cam 530 can automatically return to the unlocked position, so as to switch the locking mechanism 500 to the locked state again.

[0113] Continue to refer Fig.16 and Fig.17 The locking cam 530 may be provided with a locking protrusion 536 on one side facing away from the locking hook 510. When the locking mechanism 500 is switched to the locked state, the locking cam 530 rotates in the direction of rotation, for example Fig.17 In the direction α shown in the figure, the front side of the locking protrusion 536 is provided with a guide surface 5361, and the rear side of the locking protrusion 536 is provided with a locking recess 5362. The guide surface 5361 extends to the locking recess 5362 at an angle relative to the axial direction of the locking cam 530. The stopper 540 is swingably provided on the side of the locking cam 530 facing away from the second door body 400, with reference to Fig.18 The top of the stopper 540 has a stopper protrusion 541. When the locking mechanism 500 is in a locked state and the lock hook 510 pushes the locking cam 530 to rotate, the guide surface 5361 pushes the stopper protrusion 541, so that the stopper protrusion 541 slides along the guide surface 5361 into the locking recess 5362.

[0114] When the locking mechanism 500 switches from the unlocked state to the locked state, the guide surface 5361 of the locking protrusion 536 abuts against the stop protrusion 541 of the stop member 540. The stop member 540 can swing. The locking cam 530 rotates toward the direction α under the push of the lock hook 510. The guide surface 5361 can push the stop protrusion 541, so that the stop protrusion 541 slides along the guide surface 5361 toward the locking recess 5362 until the stop protrusion 541 enters the locking recess 5362, thereby locking the locking cam 530.

[0115] Exemplarily, a first limiting portion 5363 may be formed between the portion of the guide surface 5361 close to the locking recess 5362 and the locking recess 5362, and the first limiting portion 5363 is used to limit the stop protrusion 541 located in the locking recess 5362. When the locking mechanism 500 is in the locked state, the stop protrusion 541 is located in the locking recess 5362, and the first limiting portion 5363 can limit the stop protrusion 541 to prevent the stop protrusion 541 from escaping from the locking recess 5362, thereby improving the reliability of the locked state of the locking mechanism 500.

[0116] For example, an unlocking channel 537 may be provided between the locking protrusion 536 and the end surface of the locking cam 530, and the unlocking channel 537 extends from the locking recess 5362 to a portion of the guide surface 5361 away from the locking recess 5362. Fig.13When the locking mechanism 500 is switched to the unlocking state, the lock hook 510 continues to push the locking cam 530 to rotate in the direction α, and the stop protrusion 541 leaves the locking recess 5362 and enters the unlocking channel 537. When the second door body 400 is pulled or under the action of the first restoring force provided by the first elastic member 570, the locking cam 530 rotates in the opposite direction, and the stop protrusion 541 slides along the unlocking channel 537 to the guide surface 5361, so that when the locking structure is switched to the locking state again, the stop protrusion 541 can slide along the guide surface 5361. In this way, the locking mechanism 500 can be unlocked by pushing the second door body 400 and the lock hook 510 again, without setting an additional unlocking structure, simplifying the mechanical structure of the locking mechanism 500, reducing the volume of the unlocking mechanism, and improving the assembly convenience of the unlocking mechanism.

[0117] Exemplarily, a second limiting portion 5364 is formed between the unlocking channel 537 and the locking recess 5362, and the second limiting portion 5364 is used to limit the stop protrusion 541 located in the locking recess 5362. When the locking mechanism 500 is in the locked state, the stop protrusion 541 is located in the locking recess 5362, and the second limiting portion 5364 can limit the stop protrusion 541 to prevent the moving protrusion 541 from escaping from the locking recess 5362 and entering the unlocking channel 537, thereby improving the reliability of the locked state of the locking mechanism 500.

[0118] like Figure 7 As shown, the locking mechanism 500 may further include a second elastic member 580, and the second elastic member 580 may connect the side wall of the second accommodating cavity and the stopper 540. For example, the mounting arm 551 may be provided with a first connecting recess 556, and a first connecting protrusion 557 is provided in the first connecting recess 556. The stopper 540 may be provided with a second connecting recess 542. The second elastic member 580 may be a tension spring, a first end of the tension spring is hooked on the first connecting protrusion 557, and a second end of the tension spring is hooked in the second connecting recess 542. The second elastic member 580 may apply a second restoring force to the stopper 540, and the direction of the second restoring force is opposite to the swinging direction of the stopper 540 when the locking mechanism 500 is switched to the locked state.

[0119] refer to Fig. 9When the locking mechanism 500 switches to the locked state, the stop protrusion 541 slides along the guide surface 5361 toward the locking recess 5362, and the stopper 540 swings clockwise. The stopper 540 pulls the second elastic member 580, causing the second elastic member 580 to deform, and the second elastic member 580 generates a second restoring force opposite to the clockwise direction, that is, the second restoring force is in the counterclockwise direction. When the stop protrusion 541 slides along the guide surface 5361 to approach the locking recess 5362, the second restoring force can pull the stopper 540, causing the stopper 540 to swing counterclockwise, so that the stop protrusion 541 enters the locking recess 5362, so that the stopper 540 can lock the locking cam 530. In addition, when the locking mechanism 500 switches from the locked state to the unlocked state, the locking cam 530 continues to rotate in direction α under the push of the locking hook 510, and the stop protrusion 541 can leave the locking recess 5362 and enter the unlocking channel 537 under the action of the second restoring force, so that the locking mechanism 500 can be automatically unlocked.

[0120] The stopper 540 is swingably disposed in the second accommodating cavity. Exemplarily, the mounting bracket 550 may be provided with a second connecting protrusion 559. For example, the mounting bracket 550 may further include a fifth connecting portion 558, the fifth connecting portion 558 being located between the two mounting arms 551 and connected to the two mounting arms 551. The second connecting protrusion 559 is disposed on the fifth connecting portion 558. Fig.19 The stopper 540 may be provided with a third connection recess 543, and the third connection recess 543 is hung on the second connection protrusion 559. In this way, the stopper 540 and the mounting bracket 550 are connected through the second connection protrusion 559 and the third connection recess 543 that are hung on each other. During the swinging process of the stopper 540, the third connection recess 543 will not restrict the second connection protrusion 559, thereby increasing the swinging range of the stopper 540.

[0121] Exemplarily, the second connecting protrusion 559 can be a bending structure, which can be inserted into the third connecting recess 543 of the stop member 540. The bending structure can limit the stop member 540 to prevent the movable member 540 from detaching from the mounting bracket 550, thereby improving the structural reliability of the locking mechanism 500.

[0122] To facilitate understanding of the technical solution of the embodiment of the present application, the locking state and unlocking state of the locking mechanism 500 are described in detail below in combination with specific technical features.

[0123] refer to Figure 8 and Fig. 9When the locking mechanism 500 is switched to the locked state, a thrust F1 is applied to the second door body 400 toward the first door body 200, and the second door body 400 drives the lock hook 510 to rotate toward the first door body 200, and the lock hook 510 extends into the second accommodating cavity through the lock hole 234 to cooperate with the lock assembly 520 for locking. The second accommodating recess 534 of the locking cam 530 is opposite to the lock hole 234. After the lock hook 510 extends into the second accommodating cavity, it passes over the locking portion 533, abuts against the pushing portion 532, and pushes the pushing portion 532, so that the locking cam 530 rotates in the direction α. ​​When the locking cam 530 rotates, the locking portion 533 can be inserted into the locking through hole 511 of the lock hook 510 to lock the lock hook 510. When the locking cam 530 rotates, the first elastic member 570 is deformed, and the first elastic member 570 generates a first restoring force opposite to the direction α, and the first restoring force acts on the locking cam 530 .

[0124] When the locking cam 530 rotates in the direction α, the guide surface 5361 pushes the stop protrusion 541 of the stopper 540, so that the stop protrusion 541 slides along the guide surface 5361 toward the locking recess 5362, and the stopper 540 swings, and the stopper 540 pulls the second elastic member 580, so that the second elastic member 580 is deformed, and the second elastic member 580 generates a second restoring force opposite to the clockwise direction. When the locking portion 533 is inserted into the locking through hole 511, the stopper 540 slides to the locking recess 5362, and the stopper 540 can enter the locking recess 5362 under the action of the second restoring force provided by the second elastic member 580, so as to lock the locking cam 530.

[0125] refer to Fig.10 and Fig.11 When the locking mechanism 500 is switched to the unlocking state, a thrust F2 is applied to the second door body 400 toward the first door body 200, and the second door body 400 drives the lock hook 510 to continue to rotate toward the first door body 200, and the lock hook 510 continues to push the pushing portion 532, so that the locking cam 530 continues to rotate in the direction α. ​​The stop protrusion 541 of the stopper 540 moves in a direction away from the locking recess 5362, and enters the unlocking channel 537 under the action of the second restoring force provided by the second elastic member 580, and the stopper 540 releases the lock on the locking cam 530.

[0126] refer to Fig.12 and Fig.13, a pulling force F3 is applied to the second door body 400 away from the first door body 200, and the second door body 400 drives the lock hook 510 to move in a direction away from the first door body 200, and the lock hook 510 pulls the locking portion 533, so that the locking cam 530 rotates in a direction β opposite to the direction α. ​​Alternatively, under the action of the first restoring force provided by the first elastic member 570, the locking cam 530 rotates in the direction β, so that the second accommodating recessed portion 534 of the locking cam 530 is opposite to the locking hole 234, and the locking cam 530 releases the lock on the lock hook 510. The stop protrusion 541 of the stopper 540 moves along the unlocking channel 537 to the guide surface 5361.
