Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes in accordance with the embodiments are within the scope of the present invention.
It will be understood that terms used herein such as "upper," "lower," "outer," "inner," and the like, refer to relative spatial positions of one element or feature with respect to another element or feature as illustrated in the figures for purposes of explanation. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.
The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. As in the present invention, for convenience of description, when the refrigeration apparatus is normally used, the direction toward the ground is downward, and the direction away from the ground is upward; the direction parallel to the ground is the horizontal direction, and the direction vertical to the ground is the vertical direction; the side close to the user is the front side, and the side far away from the user is the back side.
Referring to fig. 1 to 4, a preferred embodiment of the present invention provides a linkage mechanism for a refrigeration apparatus, which is used for transmitting a rotational torque between two rotating shafts and has a function of disengageable transmission, that is, a user selectively cancels transmission connection between the two rotating shafts.
As shown in fig. 1, a linkage mechanism for a refrigeration device according to a preferred embodiment of the present invention includes a first rotating shaft 10 rotating along with a refrigeration device door pivot 60, a second rotating shaft 20 in transmission connection with the first rotating shaft 10, and a driving assembly 30 disposed in cooperation with the first rotating shaft 10. In this embodiment, the door pivot 60 can rotate correspondingly with the rotation opening and closing of the door, and may be that the door pivot 60 rotates with the rotation of the refrigeration equipment door itself, or that the door pivot 60 rotates with the rotation of the door through a transmission member.
In contrast, the first rotating shaft 10 is a driving member that obtains a rotational torque prior to the second rotating shaft 20, and the second rotating shaft 20 is a driven member, i.e., the second rotating shaft 20 rotates with the rotation of the first rotating shaft 10. Specifically, during installation, the second rotating shaft 20 can also transmit torque to the final output rotating shaft through a transmission member, or the second rotating shaft 20 may be the final output rotating shaft.
Because the torque obtained by the first rotating shaft 10 comes from the rotary opening and closing of the door body of the refrigeration equipment, the second rotating shaft 20 for outputting the torque can be connected to the corresponding rotating part in the refrigeration equipment in the later period, that is, the door body of the refrigeration equipment can be in transmission connection with the corresponding component needing to rotate in the refrigeration equipment, and the rotation of the corresponding component of the refrigeration equipment can be realized by opening or closing the door body of the refrigeration equipment, for example, the door body of the refrigeration equipment and an ice turning device of an ice maker, the door body of the refrigeration equipment and the rotary ice outlet of an ice storage box, the door body of the refrigeration equipment and a rotary ice crushing device, and the like. Of course, there are many ways to obtain the torque of the first rotating shaft 10, such as driving motor, other components in refrigeration equipment that need to rotate, and so on, which are suitable for the purpose of the present invention, as long as the torque is transmitted or directly output to the first rotating shaft 10 through a transmission member.
Further, the driving assembly 30 rotates to drive the first rotating shaft 10 to displace along the axial direction thereof, and is separated from the transmission connection with the second rotating shaft 20. In this embodiment, the first rotating shaft 10 rotates around its own axis, and when it is displaced along its own axis, the transmission members on the first rotating shaft 10 can be disengaged, thereby achieving the disengagement of the transmission connection between the first rotating shaft 10 and the second rotating shaft 20. Through set up drive assembly 30 on first rotation axis 10, do not influence first rotation axis 10 and second rotation axis 20 transmission and be connected, can also make first rotation axis 10 and second rotation axis 20 break away from the transmission and be connected as required, only need rotation drive assembly 30 order about first rotation axis 10 along its axis direction displacement can, the process of breaking away from the transmission and connecting is simple and laborsaving.
Specifically, the driving assembly 30 includes a driving shaft 31 and a driving block 33 connected to one end of the driving shaft 31. In this embodiment, the driving rotating shaft 31 may be rotatably disposed on a housing of the refrigeration equipment or other mounting rack capable of mounting the driving rotating shaft 31 through a shaft sleeve or a bearing seat, as long as the driving rotating shaft 31 can rotate around its own axis and keep its own position unchanged. Moreover, the driving block 33 also rotates around the axis of the driving rotating shaft 31, and since the driving rotating shaft 31 is fixed on the corresponding refrigeration equipment housing through a shaft sleeve, the driving rotating shaft 31 does not displace in the process of rotation, and similarly, the driving block 33 does not displace in the process of rotation, and the position of the driving block 33 is always kept inconvenient except for the rotation of the driving block.
In addition, in order to facilitate the user to operate the driving shaft 31 to rotate, an operating handle 32 may be disposed at the other end of the driving shaft 31 opposite to the driving block 33, and the operating handle 32 may be disposed outside the refrigeration device, and only the operating handle 32 needs to be operated outside the refrigeration device when the first rotating shaft 10 and the second rotating shaft 20 are required to be disconnected from the transmission connection.
Specifically, the driving block 33 abuts against the end of the first rotating shaft 10, and the driving block 33 drives the first rotating shaft 10 to displace in a direction away from the driving rotating shaft 31 after rotating. In this embodiment, since the positions of the driving shaft 31 and the driving block 33 are not changed, the driving block 33 can drive the first rotating shaft 10 to displace in a direction away from the driving shaft 31 after rotating. Of course, the first rotating shaft 10 may be driven to move toward the driving rotating shaft 31 after the driving block 33 rotates, as long as the first rotating shaft 10 is separated from the second rotating shaft 20.
As shown in fig. 2, 3a and 3b, the axis of the driving shaft 31 is in the same plane as the axis of the first rotating shaft 10. In this embodiment, the axis of the driving rotating shaft 31 and the axis of the first rotating shaft 10 are in the same plane, so that when the driving block 33 drives the first rotating shaft 10 to displace in a direction away from the driving rotating shaft 31, the displacement path is always parallel to the axis of the first rotating shaft 10.
Further, the driving block 33 has a first abutting surface 33a parallel to the axis of the driving shaft 31 and a second abutting surface 33b adjacent to the first abutting surface 33a and parallel to the axis of the driving shaft 31, and the distance between the first abutting surface 33a and the axis of the driving shaft 31 is smaller than the distance between the second abutting surface 33b and the axis of the driving shaft 31. In this embodiment, when the surface of the driving block 33 abutting against the first rotating shaft 10 is switched from the first abutting surface 33a to the second abutting surface 33b, the distance between the first rotating shaft 10 and the axis of the driving spindle 31 is increased, and the driving spindle 31 and the driving block 33 are not displaced, so that the first rotating shaft 10 is driven to be displaced in a direction away from the driving spindle.
Further, the first contact surface 33a has a planar structure, and the second contact surface 33b has an arc-shaped structure. In this embodiment, since the second abutting surface 33b is configured as a curved surface, the surface abutting on the first rotating shaft 10 can be more smoothly switched from the first abutting surface 33a to the second abutting surface 33b, so that the user can operate the rotation of the driving block 33 more easily, and the operation by the user is facilitated.
Further, the linkage mechanism further comprises a first transmission gear 11 sleeved on the first rotating shaft 10, and a second transmission gear 21 matched with the first transmission gear 11 and sleeved on the second rotating shaft 20. In the present embodiment, since the axes of the first rotating shaft 10 and the second rotating shaft 20 intersect, the first transmission gear 11 and the second transmission gear 21 each employ bevel gears matched with each other in order to transmit torque between the rotating shafts which are not parallel to each other. Of course, the first transmission gear 11 and the second transmission gear 21 may also adopt spur gear and spur gear, gear and rack, worm gear and worm that match each other, to meet different requirements.
As shown in fig. 4, the first rotary shaft 10 has a rotary shaft mounting portion 10a to which the first transmission gear 11 is fittingly mounted. In the present embodiment, the first transmission gear 11 is attached to the rotary shaft attachment portion 10a, and is capable of rotating with the first rotary shaft 10 and also capable of being displaced in the axial direction of the rotary shaft attachment portion 10a.
Specifically, the radial cross section of the rotating shaft mounting portion 10a is provided as a regular polygon. In the present embodiment, the rotary shaft mounting portion 10a is preferably formed in a regular hexagon so as to match the first transmission gear 11.
Further, the driving block 33 rotates to drive the first transmission gear 11 to disengage from the second transmission gear 21. In this embodiment, after the driving block 33 drives the first rotating shaft 10 to move along the axis thereof in a direction away from the driving rotating shaft 31, the first transmission gear 11 is disengaged from the second transmission gear 21. After the engagement, the first rotary shaft 10 can continue to rotate along with the door pivot 60, and the second rotary shaft 20 loses the transmission force and stops rotating.
As a further improvement of the present invention, with reference to fig. 4, the interlocking mechanism further includes an elastic member 40 fitted over the rotation shaft mounting portion 10a.
In this embodiment, the elastic member 40 provides a pre-tightening force to the first transmission gear 11 toward the driving rotation shaft 31, so that on one hand, the first transmission gear 11 and the second transmission gear 21 are better engaged with each other; on the other hand, when the surface contacting the first rotating shaft 10 is switched from the second contacting surface 33b to the first contacting surface 33a, the elastic member 40 drives the first rotating shaft 10 to displace toward the driving rotating shaft 31, so that the first transmission gear 11 and the second transmission gear 21 are restored to be meshed.
Therefore, after the driving device 33 is matched with the elastic element 40, the whole scheme can drive the first rotating shaft 10 to be separated from the transmission connection with the second rotating shaft 20, and can recover the transmission connection between the first rotating shaft 10 and the second rotating shaft 20, so that the first rotating shaft 10 and the second rotating shaft 20 can be selectively clutched.
In addition, in order to satisfy the axial pressure required for the engagement of the first transmission gear 11 and the second transmission gear 21, the elastic member 40 is preferably a disc spring.
Specifically, the first rotating shaft 10 further has a limit block 13 adjacent to the rotating shaft mounting portion 10a and close to one side of the driving block 33, one end of the first transmission gear 11 abuts against the limit block 13, the other end of the first transmission gear abuts against the elastic member 40, and the elastic member 40 drives the first transmission gear 11 to move in the direction close to the driving rotating shaft 31 after the driving block 33 rotates relatively, and is meshed with the second transmission gear 21. In this embodiment, the limiting block 13 plays a role in limiting the displacement of the first transmission gear 11 in the direction toward the driving rotation shaft 31, and can also drive the whole first rotation shaft 10 to displace toward the driving rotation shaft 31 when the first transmission gear 11 displaces toward the driving rotation shaft 31.
Further, the linkage mechanism further includes a connecting seat 50 for driving and connecting the door pivot 60 and the rotating shaft mounting portion 10a. In this embodiment, the door pivot 60 is in transmission connection with the first rotating shaft 10 by using the connecting seat 50. Of course, a transmission assembly may also be used to realize the transmission connection between the door body pivot 60 and the first rotating shaft 10.
Specifically, one end of the elastic member 40 abuts against the first transmission gear 11, and the other end abuts against the connecting seat 50. In this embodiment, the connecting seat 50 has a boss with an outer diameter larger than that of the elastic member 40 for abutting against the elastic member 40.
Specifically, the door pivot 60 is fixedly connected to the connecting seat 50, and the rotating shaft mounting portion 10a is in transition fit with the connecting seat 50. In this embodiment, since the transition fit is adopted between the rotating shaft mounting portion 10a and the connecting seat 50, the rotating shaft mounting portion 10a can displace along the axial direction of the connecting seat 50, and then the whole first rotating shaft 10 can displace along the axial direction of the connecting seat 50, thereby satisfying the condition that the clutch can be performed between the first rotating shaft 10 and the second rotating shaft 20.
Further, the first rotating shaft 10 further has a rotating shaft driving portion 10b adjacent to the limiting block 13 and close to one side of the driving block 33, an arc-shaped chamfer 10c is arranged at an end of the rotating shaft driving portion 10b far away from one side of the limiting block 13, and the driving block 33 abuts against the arc-shaped chamfer 10c. In this embodiment, when the first contact surface 33a contacts the rotation shaft driving unit 10b, the first rotation shaft 10 and the second rotation shaft 20 are in transmission connection, and when the second contact surface 33b contacts the rotation shaft driving unit 10b, the first rotation shaft 10 and the second rotation shaft 20 are out of transmission connection. Therefore, the rotary shaft driving part 10b is always abutted against the driving block 33, and the end of the rotary shaft driving part is provided with an arc-shaped chamfer, so that the contact area between the rotary shaft driving part 10b and the driving block 33 can be reduced, the friction force between the rotary shaft driving part 10b and the driving block 33 is reduced, the resistance brought by the driving device 30 to the rotation of the door pivot 60 is reduced, and the normal opening and closing of the refrigeration equipment door is not influenced.
Referring to fig. 5, according to another aspect of the present invention, there is also provided a refrigeration apparatus, which includes a refrigeration compartment 100 and an ice bank 110 disposed in the refrigeration compartment 100, and further includes a linkage mechanism according to the present invention, wherein the second rotation shaft 20 is drivingly connected to the ice bank 110.
In this embodiment, the door pivot 60 drives the first rotating shaft 10 to rotate, the first rotating shaft 10 drives the second rotating shaft 20 to rotate, and the second rotating shaft 20 drives the ice bank 110 to rotate after being in transmission connection with the ice bank 110. Therefore, the door body of the refrigeration equipment is connected with the ice storage box 110 in the refrigeration compartment 100 in a linkage manner, namely when the door body of the refrigeration equipment is opened or closed, the ice storage box 110 correspondingly rotates and extends out of the refrigeration compartment 100.
Moreover, when the ice storage bin 110 is used for placing and storing ice cubes, the ice storage bin can be used together with a corresponding ice making device, that is, after the ice making device finishes making ice, the ice cubes are automatically poured into the ice storage bin 110, and after the door body of the refrigeration equipment is opened, the ice storage bin 110 extends out of the refrigeration compartment 100, so that a user can conveniently take and place the ice cubes in the ice storage bin 110. In order to be used together with the ice making device, the ice making device may be disposed in the refrigerating compartment 100 and above the ice storage bin 110, so as to ensure that the ice cubes made by the ice making device fall into the ice storage bin 110.
Specifically, the refrigeration equipment further comprises a transmission shaft 120 for installing the second transmission gear 21, a third transmission gear 130 arranged at the other end of the transmission shaft 120 opposite to the second transmission gear 21, a fourth transmission gear 140 engaged with the third transmission gear 130, and a rotary output shaft 150 for installing the fourth transmission gear 140, wherein the rotary output shaft 150 is connected with the ice bank 110.
In this embodiment, since a certain distance exists between the door pivot 60 and the rotation output shaft 150 connected to the ice bank 110, the first transmission gear 11, the second transmission gear 21, the third transmission gear 130, and the fourth transmission gear 140 all adopt bevel gears.
The rotary output shaft 150 is rotatably provided in the refrigerating compartment 100 via a sleeve or a bearing housing. The door body of the refrigeration equipment rotates to drive the door body pivot 60 to rotate, then the door body pivot 60 drives the rotary output shaft 150 to rotate through the linkage mechanism and the corresponding transmission part, and the rotary output shaft 150 drives the ice storage box 110 to rotate.
Moreover, the rotating direction of the door pivot 60 is consistent with the rotating direction of the rotating output shaft 150, and the rotating direction of the refrigeration equipment door body when being opened is the same as the rotating direction of the ice storage box 110 when being screwed out of the refrigeration compartment 100, so that the door body of the refrigeration equipment is prevented from colliding or colliding with the ice storage box 110 in the opening and closing processes.
Referring to fig. 6, further, the ice bank 110 has a bottom wall 111 at a lower portion thereof, the refrigeration compartment 100 has a lower sidewall 101 at a lower portion thereof, and the rotary output shaft 150 is disposed between the bottom wall 111 and the lower sidewall 101. In this embodiment, in order to save the internal space of the cooling compartment 100, the bottom wall 111 of the ice bank 110 may be attached to the lower sidewall 101 of the cooling compartment 100. Of course, the rotary output shaft 150 may be rotatably disposed on a heat-insulating partition or other mounting plane in the refrigeration compartment 100.
Further, the rotation output shaft 150 is disposed in a symmetrical plane symmetrical to the left and right sides of the lower sidewall 101. In this embodiment, when the rotation output shaft 150 is disposed in the symmetrical plane symmetrical to the left and right sides of the lower sidewall 101, the ice bank 110 can rotate more than 180 ° in the refrigeration compartment 100.
With continued reference to fig. 7a and 7b, the rotational output shaft 150 is not only in the symmetrical plane symmetrical to the left and right of the lower sidewall 101, but also in the symmetrical plane symmetrical to the left and right of the bottom wall 111, which can ensure that the area of the bottom wall 111 is maximized while the ice bank 110 rotates more than 180 ° in the refrigeration compartment 100, and thus more ice cubes can be stored.
