Detailed Description
The embodiment of the invention firstly provides a handle assembly for a refrigerating and freezing device, and the handle assembly is arranged on a door body of the refrigerating and freezing device. Fig. 1 and 2 are schematic block diagrams of a handle assembly according to an embodiment of the present invention in different states, and fig. 3 and 4 are schematic exploded views of different orientations of the handle assembly according to an embodiment of the present invention. Referring to fig. 1 to 4, a handle assembly 1 of an embodiment of the present invention includes a base 10 and a handle 20. The base 10 is fixed on the outer surface of the door body of the refrigerating and freezing device, and is provided with a mounting part which is sunken towards the inside of the door body, namely, the mounting part is sunken backwards. The handle 20 has a first end 210 and a second end 220 pivotally coupled to the mounting portion (i.e., both ends of the handle 20 are pivotally coupled to the mounting portion). The handle 20 is selectively accommodated in the installation part on the base 10, so that the whole handle assembly 1 is positioned outside the door body, the door body is only required to be provided with a very small installation space for the handle assembly 1 or even is not required to be designed to be concave for the handle assembly 1, the thickness of a foaming layer of the door body cannot be thinned to influence the heat insulation performance of the door body, and the inner side of the door body cannot bulge to occupy the storage space inside the refrigeration and freezing device.
Further, the handle assembly 1 further comprises at least one driving mechanism 40, the at least one driving mechanism 40 being disposed on the base 10, each driving mechanism 40 being configured to controllably cause a respective end of the handle 20 to move between two positions in the mounting portion, so as to receive the handle 20 in the mounting portion when the respective end is in its own first position (see the state shown in fig. 1), and to elastically deform and arch the handle 20 toward the outside of the mounting portion when the respective end is in its own second position (see the state shown in fig. 2, which may be arched, for example). That is, at least one of the ends of the handle 20 is slidable between its own first and second positions under the driving action of a driving mechanism 40. Therefore, the handle assembly 1 can have two states of use and standing, so that the handle 20 only extends out when in the use state, does not occupy extra space when in the standing state, reduces the space occupied by the whole handle assembly 1, and reduces the space occupied by a refrigeration and freezing device using the handle assembly 1.
The handle 20 is made of a material selected so as to be elastically deformed by an external force, and can be restored to its original shape when the external force disappears. Specifically, the handle 20 may be made of an elastic material such as silicone, rubber, or the like.
The connection line between the first position and the second position of each end of the handle is parallel to the extension direction of the handle 20 itself. Specifically, the base 10 and the handle 20 are both substantially vertically elongated members, and the mounting portion in the base 10 is also substantially an elongated cavity matching the shape of the handle 20. The first end 210 of the handle 20 may be the upper end and the second end 220 may be the lower end.
In some embodiments of the present invention, a movable connecting member 112 and a fixed connecting member 111 are provided in the mounting portion, the movable connecting member 112 is movable relative to the bottom wall of the mounting portion, and the fixed connecting member 111 is fixed in the mounting portion. The first end 210 of the handle 20 is pivotally connected to the fixed link 111, and the second end of the handle 20 is pivotally connected to the movable link 112. And, the number of the driving mechanism 40 is one, the driving mechanism 40 is configured to controllably cause the movable connector 112 to move between the first position and the second position of the handle second end 220, so as to move the second end 220 of the handle 20 between the first position and the second position thereof via the movable connector 112. That is, the position of the first end 210 of the handle is relatively fixed, and the relative position of the second end 220 of the handle 20 and the first end 210 can be changed under the driving action of the driving mechanism 40, i.e. the second end 220 is slidably connected with the mounting portion.
The connection line between the first position and the second position of the handle second end 220 extends in a vertical direction. In the use state, the driving mechanism 40 drives the movable connecting piece 112 to move towards the second position of the second end 220 of the handle to drive the second end 220 of the handle to slide to the second position, so that the handle 220 is in a shape of being arched towards the outer side of the mounting part, which is convenient for a user to hold, and further, the user applies a larger acting force capable of opening the door body to the handle 20; in the resting state, the driving mechanism 40 urges the movable connector 112 toward the first position of the handle second end 220 to slidingly return the second end 220 of the handle 20 to the first position such that the entire handle 20 is received in the mounting portion.
Specifically, the mounting portion may be respectively provided with a groove at a position adjacent to the upper end portion and the lower end portion thereof, and the fixed connecting member 111 and the movable connecting member 112 are respectively disposed in the two grooves to perform a certain limiting function on the fixed connecting member 111 and the movable connecting member 112, thereby effectively preventing the fixed connecting member 111 and the movable connecting member 112 from shaking.
A coupling hole, which may be a threaded hole, for example, may be formed in the recess of the mounting portion for receiving the fixing connector 111. The fixed link 111 may include a support platform 1112 supported on and securely coupled to the bottom wall of the mounting portion and a protrusion 1113 disposed on the support platform 1112. The supporting platform 1112 is also provided with a connecting hole to fasten the fixing connector 111 to the bottom wall of the mounting portion by a connector inserted into the corresponding connecting hole of the supporting platform 1112 and the bottom wall of the mounting portion.
Fig. 5 is a schematic sectional view taken along a vertical sectional plane of the handle assembly shown in fig. 1, and fig. 6 is a schematic sectional view taken along a vertical sectional plane of the handle assembly shown in fig. 2. In some embodiments of the present invention, the drive mechanism 40 includes a motor 410 and a screw 420. The motor 410 is used for controlled activation to provide motive force. The screw 420 is connected to a rotation output shaft of the motor 410 to be rotated by the motor 410. The screw rod 420 is inserted into the movable connecting member 112 in a direction parallel to the moving direction of the second end of the handle 20 (i.e., the direction of a connecting line between the first position and the second position of the handle second end 220), and is threadedly coupled to the movable connecting member 112, so that the movable connecting member 112 moves along the screw rod 420 as the screw rod 420 rotates.
Specifically, the motor 410 may be secured to a side of the base 10 adjacent the handle second end 220, which may be concealed within a cavity formed within the base 10. The motor 410 can be fixed with the base 10 through a screw or other clamping structure, and displacement or play of the motor 410 can not be generated in the action process.
The motor 410 can be electrically connected or in signal connection with a control system of the refrigeration and freezing device, so that when a user approaches the refrigeration and freezing device and needs to open the door body, a signal for representing the opening of the door body is sent to the control system by utilizing a human sensing technology or other specially designed keys, and the control system receives the signal and then sends a control signal for controlling the forward operation of the motor 410. The forward operation of the motor 410 can cause the screw 420 to move toward the second position of the handle second end 220. When the user leaves the refrigeration and freezing device, the user can automatically sense through human sensing technology or send a signal for representing the closing of the door body to the control system through other specially designed keys, so that the motor 410 is controlled to run reversely, and the screw 420 and the second end 220 of the handle are restored to the original state.
Therefore, the at least one driving mechanism 40 drives the handle 20 to switch between the standing state accommodated in the mounting part and the using state arched outwards from the mounting part, so that a user only needs to move to the refrigeration and freezing device or press a preset key, the stability is high, the operation is simple and convenient, and the using experience of the user is improved.
