As shown in connection with fig. 1-21, embodiments of the present disclosure provide a handle assembly for a refrigerator.

The refrigerator comprises a refrigerator body and a door body 100 which can be arranged on the refrigerator body in an opening and closing mode. The door body 100 is provided with a recess; the recess may be located on the front surface of the door body 100 or may be located on the side surface of the door body 100. Wherein, the front face refers to the face opposite to the refrigerator when the refrigerator is used by a user.

The handle assembly includes a clasp box 10, a handle 20, a push rod assembly 30 and a hover mechanism 50.

The clasp box 10 is disposed within the recess. The handle 20 is arranged on the handle box 10, is movably connected with the handle box 10 and can move relative to the handle box between a hidden position in the handle box and a protruding position protruding from the handle box, as shown in fig. 4, in a hidden position, as shown in fig. 10, in a hovering position, as shown in fig. 16; the push rod assembly 30 is arranged on the buckle box and can move between an extending position for extending out of the buckle box and a retracting position for retracting the buckle box, wherein the push rod assembly is in a retracting position as shown in fig. 6 and 12, and is in an extending position as shown in fig. 18, the push rod assembly 30 is matched with a handle, and when the handle moves relative to the buckle box, the push rod assembly 30 is driven to move between the extending position and the retracting position; the hover mechanism 50 cooperates with the handle for causing the handle to be in a hover position, wherein the push rod assembly 30 is in a retracted position when the handle is in the hover position, wherein the hover position is between the hidden position and the protruding position.

From the retracted position to the extended position, the push rod assembly 30 moves toward the cabinet and abuts against the cabinet to eject the door 100 in a direction away from the cabinet, thereby achieving door opening assistance.

The door opening process may be divided into two processes, the first process is that the handle is moved from the hidden position to the hovering position, and the door body 100 is not opened in the initial stage of the handle opening; the second process is the stage in which the handle is opened from the hover position to the stand-off position, and the door 100 is opened.

In a first process, the handle is moved from a hidden position (as in fig. 2-7) to a hover position (as in fig. 8-13) where the handle is gradually protruding from the clasp box, but the push rod assembly 30 is in a retracted position, i.e., no movement of the push rod assembly 30 occurs, so that the user only needs to overcome the force of the movement of the handle relative to the clasp box to effect the opening of the door with less force.

In the second stage, the handle moves from the hovering position to the protruding position (as shown in fig. 14 to 19), at this time, more parts of the handle protrude from the buckle box, the push rod assembly 30 moves from the retracted position to the protruding position under the drive of the handle, and the push rod assembly 30 abuts against the cabinet body in the extending process, so as to jack the door body 100 open, thereby realizing door opening. The handle is operated at this stage, on the one hand, to overcome the force of the movement of the handle relative to the clasp box and also to provide the force required to drive the push rod assembly 30 out of the way, and therefore the force required is greater, but at this time the handle is more extended out of the clasp box, so the area for the graspable handle is greater and the handle is easier to operate.

Alternatively, as shown in fig. 7, 12 and 18, the handle assembly further includes a linkage assembly 40, the linkage assembly 40 being disposed between the handle and the push rod assembly 30, the handle moving the push rod assembly 30 between the extended and retracted positions via the linkage assembly 40.

The sidewall 103 of the clasp box includes a first sidewall 1031 and a second sidewall 1032.

The second side wall 1032 is disposed opposite to the first side wall 1031, the hovering portion 101 is disposed on the first side wall 1031, and the link assembly 40 is disposed on the second side wall 1032.

The arrangement ensures that the whole handle assembly occupies small space and has compact structure.

As shown in fig. 7, 12 and 18, the link assembly 40 includes a first link 401 and a second link 402. The first connecting rod 401 is movably arranged on the handle box and comprises a first end 4011 and a second end 4012, and the first end 4011 is matched with the handle; the second connecting rod 402 is movably arranged in the handle box and comprises a third end 4021 and a fourth end 4022, the third end 4021 is abutted to the second end 4012, and the push rod assembly 30 is matched with the fourth end 4022; when the handle rotates relative to the buckle box towards the protruding position, the first connecting rod 401 is driven to move, and the first connecting rod 401 drives the second connecting rod 402 to move so as to drive the push rod assembly 30 to move towards the protruding position.

The effort of handle is transmitted to push rod assembly 30 through first connecting rod 401 and second connecting rod 402 in proper order to design first connecting rod 401 and second connecting rod 402, compares in designing only one connecting rod, designs first connecting rod 401 and second connecting rod 402 in this application, under the same motion stroke's of push rod assembly 30 circumstances, can reduce the motion stroke of first connecting rod 401 and second connecting rod 402 to can reduce the space that the handle subassembly occupy.

Alternatively, the first link 401 is rotatably connected to the buckle box by a first rotation shaft 403, and the first end 4011 and the second end 4012 are respectively located on opposite sides of the first rotation shaft 403, so that when the handle is pressed down to the first end 4011 to abut, the first end 4011 is driven to move downward (toward the bottom wall 102 of the buckle box), and the second end 4012 moves upward (toward the opening of the buckle box).

Optionally, the second connecting rod 402 is rotatably connected to the buckle box through a second rotation shaft 404, and the third end 4021 and the fourth end 4022 are respectively located at two opposite sides of the second rotation shaft 404, so that when the second end 4012 drives the third end 4021 to move upwards, the fourth end 4022 moves downwards, so as to drive the push rod assembly 30 to move downwards, i.e. to move towards the cabinet.

Alternatively, the first rotation axis 403 and the second rotation axis 404 are parallel.

In this solution, when the first link 401 rotates clockwise, the second link 402 rotates counterclockwise, and the rotation of the two links is in the same plane, so that the space occupied by the handle assembly can be further reduced.

Alternatively, the first rotation shaft 403 and the second rotation shaft 404 are disposed in order in a direction from the handle to the push rod assembly 30, so that the handle transmits the force to the push rod assembly 30 through the first end 4011, the second end 4012, the third end 4021, and the fourth end 4022 in order.

Alternatively, the handle comprises a first handle part 201 and a second handle part 202, the second handle part 202 being connected to the first handle part 201 and in the protruding position the first handle part 201 protrudes outwards into the clasp box and the second handle part 202 protrudes inwards into the clasp box.

When the handle moves from the hidden position toward the protruding position, the second handle portion 202 extends inward into the handle case, driving the first end portion 4011 to move toward the bottom wall 102 of the handle case, driving the second end portion 4012 to move toward the opening of the handle case, and driving the third end portion 4021 to move toward the opening of the handle case.

The first rotation shaft 403 is located on the side of the second rotation shaft 404 facing the bottom wall 102 of the buckle box, and under the condition that the movement stroke of the second connecting rod 402 is fixed, the rotation amplitude of the first connecting rod 401 can be reduced, and the space occupied by the first connecting rod 401 is reduced, so that the volume of the whole handle assembly is reduced.

Optionally, the third end 4021 is located on a side of the second end 4012 facing the opening of the buckle box, such that when the handle moves from the hidden position toward the protruding position, the movement directions of the second end 4012 and the third end 4021 are the same, thereby driving the fourth end 4022 and the push rod assembly 30 to move in a direction approaching the cabinet.

Alternatively, the first link 401 and the second link 402 are disposed obliquely. Specifically, when the handle is in the hidden position, the second end 4012 is inclined toward the bottom wall 102 of the clasp box in a direction from the first end 4011 to the second end 4012. When the handle is in the hidden position, the fourth end 4022 is inclined in a direction from the third end 4021 to the fourth end 4022 toward a direction away from the bottom wall 102 of the clasp box.

Under the condition that the motion stroke of the push rod assembly 30 is fixed, the first connecting rod 401 and the second connecting rod 402 are obliquely arranged, so that the rotation angle of the first connecting rod 401 and the second connecting rod 402 can be reduced, and the occupied space of the first connecting rod 401 and the second connecting rod 402 is reduced.

Optionally, the second side wall 1032 is provided with a mounting channel 104, and the linkage assembly 40 is disposed within the mounting channel 104. The linkage assembly 40 abuts the channel wall of the mounting channel 104 when the handle is in the hidden position and/or the linkage assembly 40 abuts the channel wall of the mounting channel 104 when the handle is in the raised position.

The link assembly 40 is restrained by the channel walls of the mounting channel 104 on the clasp box without the need for separate restraining members, thereby simplifying the structure of the handle assembly.

The channel walls of the mounting channel 104 include a first channel wall 1041 and a second channel wall 1042, with the linkage assembly 40 abutting the first channel wall 1041 when the handle is in the hidden and hover positions, as shown in fig. 7 and 12; the second channel wall 1042 is connected to the first channel wall 1041 and disposed opposite the first channel wall 1041, and when the handle is in the protruding position, as shown in fig. 18, the connecting rod assembly 40 abuts against the second channel wall 1042.

When the handle is in the hidden position, the hovering position and any position between the hidden position and the hovering position, the first channel wall 1041 limits the link assembly 40, preventing movement of the link assembly 40, thereby maintaining the push rod assembly 30 in the retracted position; the link assembly 40 moves relative to the clasp box as the handle moves from the hover position toward the extended position, and the second side wall 1032 limits the link assembly 40 as it moves into abutment with the second channel wall 1042, the link assembly 40 ceases to move, and the push rod assembly 30 is in the extended position.

Alternatively, one of the first link 401 and the second link 402 abuts the channel wall of the mounting channel 104 when the handle is in the hidden position, and the other of the first link 401 and the second link 402 abuts the channel wall of the mounting channel 104 when the handle is in the raised position.

The rotation directions of the first link 401 and the second link 402 are opposite (one clockwise and one anticlockwise), and the second link 402 is located at one side of the first link 401 facing the opening of the buckle box, so that in the hidden position and the protruding position, different links (the first link 401 or the second link 402) are abutted against the channel wall of the mounting channel 104, limiting of the link assembly 40 is achieved, and the limiting is easier to achieve than the abutting of the same link against the channel wall of the mounting channel 104, so that the structure of the channel wall of the mounting channel 104 can be simplified.

Optionally, the first link 401 is located on a side of the second link 402 facing away from the opening of the buckle box, the first channel wall 1041 is located on a side of the second channel wall 1042 facing away from the opening of the buckle box, in the hidden position, the first link 401 abuts against the first channel wall 1041, and in the protruding position, the second link 402 abuts against the second channel wall 1042.

Optionally, in the hidden position, the second end 4012 abuts the first channel wall 1041 and in the protruding position, the third end 4021 abuts the second channel wall 1042.

The first link 401 is disposed obliquely, and in the hidden position, the second end 4012 is closer to the first channel wall 1041 than the first end 4011, and therefore, the second end 4012 is designed to abut against the first channel wall 1041.

When the handle moves towards the protruding position, the second end 4012 moves towards the second channel wall 1042, driving the third end 4021 to move the second channel wall 1042, and when the third end 4021 abuts against the second channel wall 1042, the link assembly 40 stops moving, and the push rod assembly 30 moves to the extended position. Therefore, the third end 4021 is designed to abut against the second channel wall 1042 to limit the movement limit of the link assembly 40, which is easy to implement.

Alternatively, in the hidden position, the distance between the handle and the linkage assembly 40 is greater than zero, i.e., the handle is not in contact with the linkage assembly 40, and the handle is rotated until the handle is in constant contact with the linkage assembly 40, the linkage assembly 40 is stationary, and the push rod assembly 30 maintains the retracted position, between the handle not reaching the hover position. When the handle moves to the hover position, the handle abuts against the link assembly 40, so that when moving from the hover position toward the projecting position, the handle moves the link assembly 40, and the link assembly 40 moves the push rod assembly 30 toward the projecting position.

It will be appreciated that in the hidden position, the distance between the handle and the linkage assembly 40 may also be zero, where the handle does not have a hover position.

Optionally, the handle assembly further includes a restoring member 90, the restoring member 90 being supported between the linkage assembly 40 and the clasp box, and the restoring member 90 being elastically deformed during movement of the handle from the concealed position to the raised position.

Specifically, before the handle is moved from the hidden position to the hover position, the handle is not in contact with the link assembly 40, the link assembly 40 is not displaced, and thus the restoring member 90 is not elastically deformed, and the push rod assembly 30 is in the retracted position. When the handle moves to the hovering position, the handle just contacts with the connecting rod assembly 40, when the handle continues to move, the handle presses the connecting rod assembly 40, the connecting rod assembly 40 drives the push rod assembly 30 to move towards the extending position, the reset component 90 elastically deforms, and when the acting force exerted on the connecting rod assembly 40 by the handle disappears or becomes smaller to a preset value, the reset component 90 drives the connecting rod assembly 40 to reset, and the connecting rod assembly 40 drives the push rod assembly 30 to reset.

Alternatively, the linkage assembly 40 is movably coupled to the clasp box, and the linkage assembly 40 is mated to the push rod assembly 30 and is movable relative to the push rod assembly 30.

Compare in link assembly 40 and push rod assembly 30 fixed connection, design link assembly 40 in this application can be for push rod assembly 30 motion, under the unchangeable circumstances of push rod assembly 30's motion orbit like this, can make link assembly 40's mounted position more nimble, can reduce link assembly 40 in the ascending motion stroke of push rod assembly 30's direction of motion moreover, reduce the space that link assembly 40 needs to occupy.

Optionally, the restoring member 90 is supported between the second link 402 and the buckle box, and during the movement of the handle from the hidden position to the protruding position, the restoring member 90 is elastically deformed to drive the second link 402 to restore.

As shown in fig. 7, in the hidden position, the first link 401 abuts the first channel wall 1041 to limit movement of the second end 4012 of the first link 401 toward the first channel wall 1041. The restoring member 90 limits the movement of the second link 402 in a direction that drives the push rod assembly 30 to the extended position, i.e., the force of the restoring member 90 on the second link 402 is such that the third end 4021 moves toward the second end 4012, such that the second link 402 can press the second end 4012 against the first channel wall 1041, limiting the rotation of the second end 4012 in a direction away from the second channel wall 1042, such that under the combined action of the restoring member 90 and the first channel wall 1041, the link assembly 40 is limited to the first limit position, as shown in fig. 7 and 12, when the handle is in any position between the hidden position to the hover position. As shown in fig. 18, the linkage assembly is in the second extreme position with the handle in the convex position.

Optionally, the second end 4012 is located on a side of the third end 4021 that faces the bottom wall 102 of the clasp box. The reset member 90 is supported between the third end 4021 and the clasp box.

The ability of linkage assembly 40 to be in the first extreme position is achieved by the combined action of third end 4021 on second end 4012 and first channel wall 1041 on second end 4012. The reset member 90 is supported between the third end 4021 and the clasp box such that the force of the reset member 90 is directly transferred to the third end 4021, such that the force of the third end 4021 to the second end 4012 is greater, such that the linkage assembly 40 can be stably located at the first limit position.

The linkage assembly 40 may also include only one link, such as only the first link 401 or the second link 402.

Optionally, the clasp box is provided with a hover portion 101, the hover mechanism 50 moving relative to the hover portion 101 to engage or disengage the hover mechanism 50 from the hover portion 101, wherein the handle is in a hover position when the hover mechanism 50 is engaged with the hover portion 101.

When the handle moves relative to the buckle box, the handle drives the hovering mechanism 50 to move relative to the hovering part 101, when the hovering mechanism 50 is matched with the hovering part 101, the hovering part 101 limits the hovering mechanism 50 to move further, and the handle can stay at the hovering position without the action of external force, namely, when the action force exerted on the handle is eliminated, the handle can stay at the hovering position. When hover mechanism 50 is separated from hover portion 101, the handle moves from the hover position toward the hidden or raised position.

Optionally, the handle assembly further includes a restoring member, which may be a torsion spring, and the torsion spring is sleeved on the hinge shaft. The reset piece is positioned between the handle and the buckle box, and is elastically deformed when the handle is opened; in the hover position, the force transferred by the reset element to hover mechanism 50 is less than the force of hover portion 101 on hover mechanism 50 to mate hover mechanism 50 with hover portion 101.

When the handle moves from the hidden position to the protruding position, the reset piece is elastically deformed, and the elastic force of the reset piece due to the elastic deformation is used for driving the handle to reset. However, when the handle is in the hovering position, the acting force of the elastic force transmitted to the hovering mechanism 50 is smaller than the acting force of the hovering portion 101 to the hovering mechanism 50, so that the hovering mechanism 50 cannot be driven to be separated from the hovering portion 101, the hovering mechanism 50 still cooperates with the hovering portion 101, and the handle is in the hovering position under the condition that no external force is applied to the handle.

Optionally, the hover mechanism 50 abuts against the handle case, avoiding disengagement with the handle case during movement of the hover mechanism 50.

Under the action of the handle, the hover mechanism 50 moves circumferentially around the hover portion 101.

As shown in fig. 20, the hovering part 101 has a position a, a position B, a position C, and a position D in this order, and when the hovering mechanism 50 is at the position a, the handle is at the hidden position, when the hovering mechanism 50 is at the position B, the handle is at the hovering position, and when the hovering mechanism 50 is at the position C, the handle is at the protruding position.

The hover mechanism 50 moves from the hidden position through the hover position to the raised position as it passes sequentially at a, B, and C, and returns from the raised position to the hidden position as it moves from C through D to a.

By the circumferential movement of the hover mechanism 50 around the hover portion 101, a reciprocating movement of the handle between the hidden position and the protruding position is achieved.

Alternatively, as shown in FIG. 4, the hover portion 101 is provided on a sidewall 103 of the clasp box; the hover mechanism 50 includes a slider 501 and a hover mating portion.

The slider 501 is matched with the handle; the hover mating portion is disposed on the slider 501, and when the handle moves relative to the grip box, the slider 501 is driven to move relative to the grip box, the hover mating portion moves relative to the hover portion 101 under the drive of the slider 501, and moves between a locked position (as shown in fig. 9) mated with the hover portion 101 and an unlocked position (as shown in fig. 3 and 15) separated from the hover portion 101.

As shown in fig. 9, when the hover mating portion mates with hover portion 101, hover portion 101 locks the hover mating portion, hover mechanism 50 stops moving, and the handle is in a hover position. When the hover mating portion is separated from hover portion 101, hover mechanism 50 may move with the handle, which moves toward the hidden or protruding position.

The hover mating portion includes a ram 502, and when the handle moves relative to the clasp box, the slider 501 is driven to move, and the slider 501 drives the ram 502 to move relative to the hover portion 101 to mate with or separate from the hover portion 101.

Alternatively, the ejector rod 502 is provided on the side of the slider 501 facing the hovering portion 101; the ejector pin 502 is movable relative to the slider 501 toward and away from the hovering portion 101 to engage with or disengage from the hovering portion 101.

When the ejector 502 is mated with the hover portion 101, the handle is in a hover position; when the ejector 502 is separated from the hovering portion 101, the handle moves towards the hidden position or the protruding position.

One end of the buckle box is opened, and the handle cover is arranged at the opening in the hidden position. The clasp box also has a bottom wall 102 of the clasp box and a side wall 103 of the clasp box, the side wall 103 of the clasp box being connected to the bottom wall 102 of the clasp box and extending circumferentially of the bottom wall 102 of the clasp box.

Alternatively, the handle and the clasp box are rotatably connected by a hinge shaft 203, and the first rotation shaft 403 and the second rotation shaft 404 are perpendicular to the hinge shaft 203.

As shown in fig. 4, 10 and 16, the handle assembly further includes a first elastic member 60, the first elastic member 60 is connected between the handle and the slider 501, and when the handle moves relative to the buckle box, the handle drives the first elastic member 60 to move so as to drive the slider 501 to move relative to the buckle box; the hover mechanism 50 further comprises a second elastic member 70, the second elastic member 70 being supported between the slider 501 and the ejector 502 for driving the ejector 502 to move towards the hover portion 101.

One end of the first elastic member 60 is connected with the handle, the other end of the first elastic member 60 is connected with the slider 501, and when the handle moves relative to the buckle box, the slider 501 is driven to move relative to the buckle box by the first elastic member 60. When the slider 501 moves relative to the knob box, the ejector rod 502 moves with the slider 501 relative to the knob box, and movement of the ejector rod 502 relative to the hovering portion 101 is achieved.

The handle is connected with the sliding block 501 through the first elastic piece 60, compared with the connection by adopting a rigid piece, the first elastic piece 60 can deform, so that the movement amplitude of the sliding block 501 can be slowed down, the movement amplitude of the ejector rod 502 can be slowed down, the size of the hovering part 101 can be designed to be smaller, and the requirement on the size of the buckling hand box is reduced.

When the slider 501 moves the ejector 502 relative to the buckle box, the ejector 502 may move in the longitudinal direction of itself (the ejector 502) and away from the hovering portion 101, and thus, the second elastic member 70 is provided. When the ejector rod 502 moves along the length direction of the ejector rod 502 (the ejector rod 502) and away from the hovering portion 101, the second elastic piece 70 deforms, so that the ejector rod 502 can be driven to reset, and the ejector rod 502 is always abutted against the handle box.

The included angle between the deformation direction of the second elastic member 70 and the hinge shaft 203 is smaller than the included angle between the deformation direction of the first elastic member 60 and the hinge shaft 203, for example, the deformation direction of the second elastic member 70 is parallel to the hinge shaft 203, and the deformation direction of the first elastic member 60 is perpendicular to the hinge shaft 203.

The arrangement can lead the whole handle assembly to occupy small space and compact structure.

Optionally, the clasp box is provided with a chute 105, the hover mating portion being in abutment with a bottom wall of the chute 105 and moving relative to the chute 105.

The handle assembly further comprises a limiting protrusion 80, wherein the limiting protrusion 80 is arranged in the chute 105, a limiting groove 107 is defined between the limiting protrusion 80 and the side wall of the chute 105, and the hovering matching part moves around the circumference of the limiting protrusion 80; the circumferential surface of the limit projection 80 comprises a first circumferential surface 801 and a second circumferential surface 802, the second circumferential surface 802 being connected to the first circumferential surface 801 and forming a bend 803 (at B) at the connection, the hover 101 comprising the bend 803.

The ejector rod 502 moves along the first circumferential surface 801 and the second circumferential surface 802, and when moving to the bending 803, the bending 803 can play a limiting role on the ejector rod 502, so that the hovering mechanism 50 is located at a locking position, and the corresponding handle is located at a hovering position.

The limit protrusion 80 further includes a third circumferential surface 804, where the third circumferential surface 804 is connected to an end of the first circumferential surface 801 facing away from the second circumferential surface 802 and an end of the second circumferential surface 802 facing away from the first circumferential surface 801, and the D corresponds to the third circumferential surface 804.

Optionally, as shown in fig. 3, a positioning groove 106 is provided on the bottom wall of the chute 105 at a position corresponding to the hidden position, in which the hovering engagement portion is supported on the side wall of the positioning groove 106, preventing the ejector 502 from moving from the hidden position toward the third circumferential surface 804.

The groove side walls of the positioning groove 106 are communicated with the bending 803, so that the ejector rod 502 can move from the groove side walls of the positioning groove 106 to the bending 803. However, when the ejector rod 502 slides from the positioning groove 106, the ejector rod 502 is abutted against the bottom wall of the positioning groove 106, so that the ejector rod 502 moves stably, and the ejector rod 502 is prevented from being separated from the buckle box.

The height of the limit projection 80 is greater than the height of the positioning groove 106.

Under the condition that the ejector rod 502 is abutted against the bottom wall of the chute 105, when the ejector rod 502 moves to the position of the bending 803, the ejector rod 502 and the limiting protrusion 80 have larger contact area due to larger height of the limiting protrusion 80, so that friction force between the top plate and the position of the bending 803 is increased, and the handle can be stably positioned at a hovering position.

As shown in fig. 20, one end of the limiting groove 107 is at a, and the end opposite to the a is at C. The limiting groove 107 includes a first groove section 1071 and a second groove section 1072 that are in communication, the first circumferential surface 801 and the second circumferential surface 802 are groove sidewalls of the first groove section 1071, and the third circumferential surface 804 is a groove sidewall of the second groove section 1072.

From the second groove section 1072 to the positioning groove 106, the groove bottom wall of the second groove section 1072 is gradually inclined toward the direction approaching the middle of the buckle box, so that the handle can move from the protruding position to the hiding position with small force, and thus the ejector rod 502 moves toward the direction approaching the middle of the buckle box during the movement.

The movement direction of the ejector pin 502 is not parallel to the movement direction of the slider 501.

When the handle is rotated from the hidden position toward the protruding position, the first handle portion 201 gradually protrudes outwardly into the clasp box, and the second handle portion 202 gradually protrudes into the clasp box. As the second handle portion 202 extends into the grip box, the second handle portion 202 compresses the first elastic member 60, the first elastic member 60 drives the slider 501 to move in a direction away from the second handle portion 202, and the ejector 502 has two directions of movement, one of which is in a direction passing through the a, B, and C in this order, the other of which is in a direction away from the second handle portion 202, and the other of which is in a direction toward the middle of the grip box, compressing the second elastic member 70, or stretching the second elastic member 70.

As shown in fig. 15 and 20, the first circumferential surface 801 includes a first sub-surface 8011 and a second sub-surface 8012 connected, and the first sub-surface 8011, the second sub-surface 8012, and the second circumferential surface 802 are sequentially disposed in a direction from a, B, to C.

In the direction from a, B to C, the first sub-surface 8011 is inclined towards the direction away from the groove bottom wall of the limit groove 107, and the first sub-surface 8011 is inclined towards the direction close to the groove bottom wall of the limit groove 107. The junction of the first sub-surface 8011 and the second sub-surface 8012 forms a bend 8013.

In the direction from C, D to a, the third circumferential surface 804 is inclined towards the groove bottom wall facing away from the limit groove 107, optionally the third circumferential surface 804 is circular arc shaped to guide the smooth movement of the ejector 502 from C to a through D.

As shown in fig. 4, the surface of the slider 501 includes a first surface 5011 and a second surface 5013, the first surface 5011 is provided with a fitting portion 5012 for fitting with a handle, and the fitting portion 5012 protrudes from the first surface 5011 to be connected with the first elastic member 60 to achieve connection of the slider 501 with the first elastic member 60.

The second surface 5013 is connected with the first surface 5011 and the joint forms a folding angle, the second surface 5013 is provided with an assembly channel 5014, the ejector rod 502 and the second elastic member 70 are positioned in the assembly channel 5014 and move along the axial direction of the assembly channel 5014, and the deformation direction of the second elastic member 70, the length direction of the ejector rod 502 and the axial direction of the assembly channel 5014 are parallel or coincident.

As shown in fig. 6, the axial direction of the fitting channel 5014 is not parallel to the second surface 5013, avoiding that the axial direction of the fitting channel 5014 is perpendicular to the first surface 5011.

If the axial direction of the fitting channel 5014 is perpendicular to the first surface 5011, the longitudinal direction of the ejector pin 502 is perpendicular to the first surface 5011, resulting in the same movement direction of the ejector pin 502 and the slider 501.

The end of the fitting passage 5014 facing away from the jack 502 is provided with a rear plate 503 to restrict the second elastic member 70 from coming out of the fitting passage 5014.

The handle assembly further comprises a limiting plate 108, wherein the limiting plate 108 is arranged on the handle box, and the limiting plate 108 and the handle are respectively arranged on two opposite sides of the sliding block 501.

The first elastic piece 60 and the limiting plate 108 are respectively located at two opposite sides of the sliding block 501, when the first elastic piece 60 drives the sliding block 501 to move towards the limiting plate 108, the limiting position of the sliding block 501 is in abutting connection with the limiting plate 108, and therefore the limiting plate 108 can prevent the sliding block 501 from being separated from the buckle box under the action of the first elastic piece 60.

Optionally, both the hover mechanism 50 and the linkage assembly 40 are mated with the second handle portion 202.

This design enables both the linkage assembly 40 and the hover mechanism 50 to be located on the side of the handle that faces the bottom wall 102 of the buckle box, thereby avoiding the linkage assembly 40 and hover mechanism 50 protruding out of the buckle box.

When the handle is required to protrude from the buckle box, the first handle part 201 can be pulled, or the second handle part 202 can be pressed.
