Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. However, these examples are not intended to limit the present invention, and structural, methodical, or functional changes that may be made by one of ordinary skill in the art in light of these examples are intended to be within the scope of the present invention.

Referring to fig. 1 to 6, the present embodiment provides a refrigerator 100, and specifically referring to fig. 1, the refrigerator 100 includes a refrigerator body 1, a plurality of door bodies, and a turning beam 4.

The main body of the refrigerator body 1 generally includes a housing forming the appearance of the refrigerator 100, an inner container sleeved in the housing, and an insulating layer filled between the housing and the inner container, and the main body of the refrigerator body 1 defines at least one storage compartment with a front opening, and in particular, the inner container generally encloses the storage compartment. Each storage compartment can be constructed into a freezing chamber corresponding to a freezing temperature zone, a refrigerating chamber corresponding to a refrigerating temperature zone, a temperature changing chamber adjusted according to needs, or compartments corresponding to other temperature zones according to storage requirements.

The front part of each storage chamber is matched and connected with a corresponding door body.

In this embodiment, the refrigerator 100 is a side-by-side combination refrigerator, the front portion of the storage compartment 10 is coupled to the first door 2 and the second door 3 opposite to the first door 2, and the first door 2 and the second door 3 are used for opening and closing the storage compartment 10.

Referring to fig. 1 and 2, the turnover beam 4 is provided as a long member in the first direction L, preferably a long straight member in the first direction L, and is rotatably coupled to the inside of the first door body 2 about an axis T in the first direction L. Specifically, the pivoting side 401 of the turning beam 4 is rotatably coupled to the first door body 2 around the axis T through the hinge mechanism 70, the hinge mechanism 70 includes a fitting shaft 72 fixedly disposed on the first door body 2 and a hinge shaft 71 connected to the turning beam 4, and the fitting shaft 72 and the hinge shaft are rotatably coupled around the axis T to realize the relative rotation between the turning beam 4 and the first door body 2.

In the rotation travel of the rocker beam 4, the rocker beam 4 has an extended position and a retracted position relative to the first door body 2, wherein: corresponding to the opening state of the first door body 2, the turnover beam 4 is located at the retraction position, the free side 402 rotates to the inside of the first door body 2 around the axis T, and the sealing surface 400 is approximately vertical to the first door body 2; corresponding to the closed state of the first door body 2, the turning beam 4 is located at the unfolding position, the free side 402 thereof rotates around the axis T to the outside of the first door body 2 (i.e. the first door body 2 protrudes laterally), and the sealing surface 400 thereof is substantially parallel to the first door body 2. That is, the angle of rotation of the turnover beam 4 between the deployed position and the stowed position is substantially 90 °, although in practice, the angle may be adjusted accordingly as required, and is not limited thereto.

In the present embodiment, the first direction L is exemplified as being vertically upward, i.e., the turnup beam 4 extends vertically to be configured as a vertical beam. When both the first door body 2 and the second door body 3 are in the closed state, the turnover beam 4 is located at the deployed position and the free side 402 extends into the rear of the open side (e.g., the left side in the drawing) of the second door body 3 for closing the gap between the first door body 2 and the second door body 3. Of course, in a modified embodiment, the first direction L may also be changed into a horizontal direction, that is, the turning beam 4 extends horizontally and is configured as a cross beam, such as the door body 2 'and the door body 3' for opening and closing the bottom freezer compartment illustrated in fig. 1, which are arranged as straight-opening drawer type door bodies (i.e., the door body 2 'and the door body 3' are respectively assembled and connected with the freezer compartment drawer and can open and close the corresponding freezer compartment drawer by pushing and pulling back and forth), the door body 2 'and the door body 3' are arranged side by side, the turning beam 4 may also be rotatably connected to one of the door body 2 'and the door body 3' along a horizontal axis, and when the door body 2 'and the door body 3' are both in the closed state, the turning beam 4 is located at the unfolded.

As background art proposes, in the prior art, when a door body loaded with a turnover beam is opened, due to the reason that the door opening speed is too fast or the door body is turned over artificially, the turnover beam is often turned over from the retracted position to the extended position by mistake, so that the door is closed abnormally, inconvenience is caused when a user uses the door, and the turnover beam is also damaged due to collision during the door closing.

In order to solve this problem, the refrigerator 100 of the present embodiment is provided with a locking assembly, which is at least used to lock the turning beam 4 at the storage position when the first door 2 is in the open state, and unlock the turning beam 4 when the first door 2 is opened and closed.

Specifically, referring to fig. 3 to 6, the locking assembly includes a locking portion 64, a locking member 63, and a drive mechanism.

The locking portion 64 is fixedly disposed on the first door body 2, and in this embodiment, is specifically fixedly disposed on the matching shaft 72.

The lock member 63 is provided to the tilt beam 4 so as to be rotatable about the pivot axis X, and has a driven portion 631 engaged with the driving mechanism and an engaging portion 632 engaged with the lock portion 64. The driving mechanism drives the lock 63 to rotate about the pivot X by the driven portion 631, and has an unlock position and a lock position in a rotational stroke of the lock 63.

Therefore, compared with the prior art, when the first door body 2 is in an open state, the problem that the turnover beam 4 is accidentally turned to the unfolding position from the folding position due to human reasons or too high door opening speed can be avoided, and the abnormal problems that the turnover beam 4 is collided and cannot be closed in the closing process of the first door body 2 and the like are further avoided.

In addition, on the projection plane perpendicular to the pivot axis X, the distance R between the driven part 631 and the pivot axis X is smaller than the distance M between the engaging part 632 and the pivot axis X, so that the stroke can be enlarged by the locking member 63, and the driving mechanism drives the driven part 631 to move a smaller distance, that is, the engaging part 632 can realize a larger movement stroke, thereby facilitating the improvement of the reliability and fault tolerance of the turnover beam 4.

Further, the drive mechanism has a variety of implementations. For example, the driving mechanism may be provided as a motor which is provided on the turning beam 4 and whose output shaft is coupled to the driven part 631, and when the first door body 2 is opened and closed, the motor drives the lock member 62 in the forward direction to rotate from the lock position to the unlock position, and when the first door body 2 is in the open state, the motor drives the lock member 62 in the reverse direction to rotate from the unlock position to the lock position.

In the present embodiment, the driving mechanism includes a trigger 62 movably disposed on the turning beam 4, and a reset member. The trigger 62 has a trigger end 622 that mates with the case 1 and a driving portion 621 that mates with the driven portion 631.

When the first door body 2 is in an open state, the triggering end 622 of the triggering piece 62 protrudes out of the turnover beam 4; when the first door body 2 is closed, that is, the process of changing from the open state to the closed state, along with the closing of the first door body 2, the turning beam 4 is gradually close to the box body 1, the box body 1 pushes the trigger end 622 along the second direction perpendicular to the pivot axis X, so that the trigger end 622 retracts into the turning beam 4, and then the locking piece 63 is driven to rotate to the unlocking position from the locking position, so as to unlock the turning beam 4.

In this embodiment, the second direction is parallel to the longitudinal extension of the tilting beam 4, more specifically, the second direction is opposite to the first direction L, i.e. vertically downwards. Of course, in a variant embodiment, said second direction may be varied so as not to be parallel to the longitudinal extension of the overturning beam 4, or may also be arranged vertically upwards (for example at the lower end of the overturning beam as in embodiment 2).

When the first door body 2 is opened, the reset member drives the trigger member 62 to move in the opposite direction of the second direction (i.e. vertically upward in this embodiment), so that the trigger member 62 drives the locking member 63 to rotate from the unlocking position to the locking position, and the matching portion 632 is matched with the locking portion 64, so as to lock the turning beam 4.

The reset piece has various implementations, for example:

in this embodiment, the reset member is an elastic body 65, specifically, any one of a pressure spring, a tension spring, a torsion spring and a spring sheet, which is disposed between the turning beam 4 and the trigger member 62, so that when the first door body 2 is closed, the box body 1 overcomes the elastic force of the elastic body in the second direction (in this embodiment, vertically downward) to push the trigger end 622 to retract into the turning beam 4, and when the first door body 2 is opened, the turning beam 4 is away from the box body 1 with the opening of the first door body 2, the trigger end 622 loses the pushing force from the box body 1, and at this time, under the elastic force action of the elastic body, the trigger member 62 resets in the direction opposite to the second direction (in this embodiment, vertically upward);

in an alternative embodiment, the reset member may include a magnet and a ferromagnetic body magnetically coupled to the magnet, the magnet is configured as an electromagnet or a permanent magnet, the ferromagnetic body may be a metal block of iron, cobalt, nickel, gadolinium, or other ferromagnetic alloy, preferably a soft iron block and a silicon steel block that are not magnetized, or may be another permanent magnet coupled to the electromagnet or the permanent magnet; one of the magnet and the ferromagnetic body is fixedly arranged on the trigger piece 62 and the other is fixedly arranged on the overturning beam 4; when the first door body 2 is opened, after the trigger end 622 loses the pushing force from the box body 1, the magnet and the ferromagnetic body cooperate through magnetic force to drive the trigger 62 to reset along the direction opposite to the second direction (in this embodiment, vertically upward); wherein the magnetic force may be a magnetic attraction force or a magnetic repulsion force;

in a further modified embodiment, the reset element may be a motor disposed on the turning beam 4, and an output shaft of the reset element is coupled to the trigger element 62, so that a door state sensing device is configured to sense an opening state signal or an opening action signal of the door, and after sensing the opening state signal or the opening action signal, the control device of the refrigerator 100 controls the motor to drive the trigger element 62 to reset along a direction opposite to the second direction (in this embodiment, vertically upward).

Further, in the present embodiment, the locking member 62 includes an extension arm protruding outward from the pivot axis X, and the engagement portion 632 is formed at a free end of the extension arm; the driven part 631 is provided as meshing gears distributed around the arc of the pivot axis X, the distance R between the driven part 631 and the pivot axis X being the radius R of the meshing gears; that is, the distance M between the fitting portion 632 and the pivot axis X is larger than the radius R of the meshing gear.

The driving portion 621 of the triggering member 62 is configured as a rack gear coupled with the meshing gear, and the rack gear extends along the second direction, i.e. parallel to the longitudinal extension direction (i.e. the first direction L) of the turnover beam 4 in this embodiment.

Further, in order to realize the rotation of the turnover beam 4 with the opening and closing of the first door 2, the box 1 further includes a guide groove 51 provided in the main body of the box 1, and the turnover beam 4 includes a guide protrusion 52 provided at one lengthwise end (upper end in the present embodiment) thereof.

Specifically, in the present embodiment, the main body of the box body 1 is fixedly installed with a box seat 50, the box seat 50 can be fixedly installed at the front edge of the liner, and the guide groove 51 is concavely arranged on the box seat 50 along the first direction L (i.e. upward); the guide projection 52 is provided at the upper end of the turnover beam 4.

When the first door body 2 is in a closed state, the guide projection 52 stops at the guide groove 51, and the turnover beam 4 is located at the unfolding position; when the first door body 2 changes from the closed state to the open state, that is, when the first door body 2 is opened, the guide projection 52 slides along the guide groove 51 to guide the turning beam 4 to rotate from the unfolding position to the folding position; as the first door body 2 gradually moves away from the cabinet 1, the guide projection 52 finally separates from the opening end 511 of the guide slot 51, and at this time, the first door body 2 is in the open state; on the contrary, when the first door body 2 is changed from the open state to the closed state, that is, when the first door body 2 is closed, as the first door body 2 gradually approaches the cabinet 1, the guide protrusion 52 enters the guide groove 51 from the open end 511 of the guide groove 51 and moves along the guide groove 51 until reaching the tail end 512 of the guide groove 51, so as to guide the turning beam 4 to rotate from the retracted position to the extended position.

In the present embodiment, the triggering member 62 is provided integrally with the guide projection 52, i.e., the guide projection 52 is also configured as the triggering end 622 of the triggering member 62. That is, the guide projection 52 is movably provided on the turnover beam 4.

Therefore, when the first door body 2 is closed, the guide projection 52 is in sliding fit with the guide groove 51 on one hand to guide the turning beam 4 to rotate from the retracted position to the deployed position, and on the other hand, the guide projection 52 is also retracted into the turning beam 4 along the second direction (vertically downward in the embodiment) under the support of the guide groove 51 of the box body 1, so that the turning beam 4 is unlocked.

Further, the case 1 includes an abutting portion 510, and in the present embodiment, the abutting portion 510 is configured as a groove bottom surface of the guide groove 51, and the groove bottom surface is a plane horizontally extending from the opening end 511 to the tail end 512; correspondingly, the triggering end 622 has a distal end surface 670 disposed away from the turnover beam 4 in a direction opposite to the second direction (i.e., vertically upward in this embodiment), and the distal end surface 670 is disposed to extend obliquely in the second direction (i.e., vertically downward in this embodiment) from the apex end 672 to the starting end 671 thereof; when the first door body 2 is closed, the abutting portion 510 abuts against and matches the start end 671 and the vertex end 672 in sequence, so as to push the trigger 62 to retract gradually in the turnover beam 4 along the second direction (i.e. vertically downward in this embodiment).

Compared with the prior art, the embodiment has the following beneficial effects:

(1) when the first door body 2 is in an open state, the turnover beam 4 can be locked at the retraction position, so that the turnover beam 4 is prevented from being accidentally turned from the retraction position to the expansion position, and the abnormal problems that the turnover beam 4 is collided, cannot be closed and the like in the closing process of the first door body 2 are further avoided;

(2) by setting the distance R from the driven part 631 to the pivot X to be smaller than the distance M from the matching part 632 to the pivot X, the stroke can be enlarged by the locking member 63, so that the driving mechanism drives the driven part 631 to move a smaller distance, that is, the matching part 632 can realize a larger movement stroke, on one hand, the height of the guiding projection 52 or the triggering end 622 of the triggering member 62 protruding out of the turnover beam 4 does not need to be too large, and correspondingly, the depth of the guiding groove 51 does not need to be too large, thereby ensuring the aesthetic property of the product and reducing the process difficulty; on the other hand, even if the position deviation of the turnover beam 4 in the longitudinal direction occurs, the effective unlocking and locking of the turnover beam 4 can be ensured, and the reliability and the fault tolerance are improved.

Example 2

Referring to fig. 7-9, the present embodiment provides a refrigerator, referring to fig. 1 to 2 of embodiment 1, the refrigerator 100 of the present embodiment also includes a refrigerator body 1, a plurality of doors, and a turning beam 4, and in order to solve the problem in the prior art that the turning beam 4 may be turned over incorrectly when the first door 2 is opened, the refrigerator 100 of the present embodiment also includes a locking part 64, a locking piece 63, and a driving mechanism.

The main points of this embodiment and the foregoing embodiment 1 are: the specific structure of the locking member 63, the specific structure of the drive mechanism, and the position of the triggering member 62 on the overturning beam 4; the same technical contents as those of the foregoing embodiment 1 are omitted below, and only the technical contents different from those of embodiment 1 will be described.

In the present embodiment, the turning beam 4 extends lengthwise along a first direction L, which is also set vertically upward as in embodiment 1, and one lengthwise end (i.e., the upper end) of the turning beam 4 is fitted to the box body 1 through a guide mechanism, specifically, the guide mechanism includes a guide groove 51 provided on the box base 50 of the box body 1, and a guide projection 52 projecting upward from the turning beam 4, and when the first door body 2 is closed or opened, the guide projection 52 slides along the guide groove 51 to guide the turning beam 4 to rotate between the unfolded position and the stowed position.

Unlike the foregoing embodiment 1, in the present embodiment, the guide protrusion 52 is fixedly disposed on the turnover beam 4 by means of a screw, a snap, or an integral molding, and is only used for guiding the turnover of the turnover beam 4; while the triggering end 622 of the triggering member 62 projects out of the lengthwise other end (i.e., the lower end) of the flip beam 4. Like this, can realize the separation of upset roof beam 4 pivoted direction function and upset roof beam 4 unblock function, need not to rely on direction arch 52 to realize the unblock to upset roof beam 4, can not receive extra resistance when leading to upset roof beam 4, guarantee that upset roof beam 4 can rotate smoothly and target in place, and then guarantee sealed effect.

Further, when the first door body 2 is in the open state, the triggering end 622 of the triggering piece 62 protrudes downwards out of the turnover beam 4; when first door body 2 closes, also be the process that is closed state by the open mode change, along with the closing of first door body 2, upset roof beam 4 is close to box 1 gradually, and box 1 promotes trigger end 622 along first direction L, makes trigger end 622 retract in to upset roof beam 4, and then drives locking piece 63 by locking position rotates extremely unblock position to with upset roof beam 4 unblock.

Correspondingly, in order to enable the trigger member 62 to drive the locking member 63 to reset to the locking position when the first door body 2 is opened, a resetting member is provided in embodiment 1; in contrast, in the present embodiment, when the first door 2 is opened, the triggering member 62 moves vertically downward under the action of gravity to drive the locking member 63 to rotate to the locking position, and the engaging portion 632 engages with the locking portion 64.

Thus, the trigger 62, the transmission lever 66 and the locking member 63 are constructed in a three-link structure, thereby achieving the effect of converting the movement of the trigger 62 in the vertical direction into the rotation of the locking member 63.

In addition, in the foregoing embodiment 1, the groove bottom surface of the guide groove 51 is also configured as an abutting portion for abutting against the push trigger end 622; in contrast, in the embodiment, since the guide mechanism and the trigger 62 are separately disposed at the two opposite ends of the turning beam 4, the box body 1 is further separately provided with a supporting portion, the supporting portion can be specifically located at the front portion of the inner container of the box body 1 and below the turning beam 4, the supporting portion includes a head end and a tail end, and the supporting portion is provided with a supporting surface horizontally extending from the head end to the tail end; the initiation end 622 has a distal end face 670 disposed away from the turnover beam 4, the distal end face 670 being disposed to extend obliquely vertically upward from an apex end 672 thereof to a start end 671 thereof; therefore, when the first door body 2 is closed, the abutting surface abuts against and matches the start end 671 and the vertex end 672 in sequence, that is, the abutting surface abuts against the start end 671 and then abuts against the vertex end 672, so as to push the trigger 62 to retract gradually towards the interior of the turnover beam 4 along the vertical direction.
