[0001] The present application relates to the technical field of refrigeration equipment, and particularly relates to a handle assembly for a refrigeration equipment and the refrigeration equipment. BACKGROUND

[0002] At present, the main door opening mode of the existing refrigerator is to open the door through a handle. The handle is mostly protruding and fixed on the side of the door body or integrated with the door frame. However, the protruding handle increases the occupied space of the refrigerator, reduces the operable space of the side of the refrigerator, and brings inconvenience to the user when opening the door.

[0003] To solve the above problems of the protruding handle, the related technology discloses a handle assembly for a refrigerator. The handle is rotationally connected with a handle box and can rotate relative to the handle box between a hidden position in the handle box and a protruding position protruding from the handle box. A push rod assembly is drivingly connected with a first connecting rod and a second connecting rod, and the push rod assembly can move between an extended position extending out of the handle box and a retracted position retracting into the handle box. When the handle rotates towards the protruding position, the first connecting rod is driven to move, and the second connecting rod is driven to move to drive the push rod assembly to move towards the extended position. By arranging the first connecting rod and the second connecting rod, the movement stroke of the first connecting rod and the second connecting rod can be reduced under the same movement stroke of the push rod assembly, so that the space occupied by the handle assembly can be reduced.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0048] Combine Figures 1-7 As shown, an embodiment of the present disclosure provides a handle assembly for refrigeration equipment, including an embedded box 10 , a handle 20 and a drive mechanism 30 .

[0049] The embedded box 10 encloses an installation space 11; the handle 20 is provided in the installation space 11, the handle 20 is movably connected to the embedded box 10, and the handle 20 can move relative to the embedded box 10 between a hidden position located in the installation space 11 and an open position protruding from the installation space 11; the driving mechanism 30 is drivingly connected to the handle 20 to drive the handle 20 to move relative to the embedded box 10 between the hidden position and a hovering position, the hovering position protruding from the installation space 11 and being between the hidden position and the open position; wherein the driving mechanism 30 includes a driving member 31 and a gear set 32, the driving member 31 is drivingly connected to the gear set 32, the gear set 32 ​​is transmission-connected to the handle 20, the driving member 31 drives the gear set 32 ​​to rotate, so that the gear set 32 ​​drives the handle 20 to rotate.

[0050] The refrigeration device described in the present application may be a freezer, a refrigerator, etc. The refrigeration device includes a door body 80 , and a handle assembly is provided on the door body 80 .

[0051] The embedded box 10 encloses the installation space 11, and the handle 20 is movably connected to the embedded box 10. The handle 20 can be hidden in the installation space 11, and the handle 20 can also be protruded outside the installation space 11 by rotating. The position where the handle 20 protrudes outside the installation space 11 includes a hovering position and an open position, and the hovering position is between the hidden position and the open position. When the handle 20 is not in use, the handle 20 is in the hidden position in the installation space 11 (such as Figure 3 When the handle 20 needs to be used, the drive mechanism 30 can be used to drive the handle 20 to a hovering position, protruding from the installation space 11, making it easier for the user to grasp the handle 20. At this point, the handle 20 protrudes from the installation space 11. The user pulls on one end of the handle 20, and lever transmission can be used to assist in opening the door. The handle 20 continues to move from the hovering position toward the outside of the installation space 11 to the open position, thereby opening the door 80 of the refrigeration unit. The movement of the handle 20 between the hovering position and the open position can be achieved with user assistance or by electric drive.

[0052] The handle 20 is in a hidden position in the installation space 11 of the embedded box 10 when not in use. In this way, the protruding handle 20 can avoid occupying the space on the side of the refrigeration equipment, reduce the obstruction to the operation space of the user, thereby improving the space utilization. When the handle 20 needs to be used, the handle 20 is driven by the driving mechanism 30 to move from the hidden position to the hovering position, and the handle 20 can be kept in the hovering state through the meshing of the gear set 32, so that the user can easily grasp the handle 20. This automatic movement reduces the manual operation steps, making the door opening process more convenient and fast, thereby improving the automation degree of the refrigeration equipment door opening. At the same time, the driving member 31 drives the gear set 32 to rotate to drive the handle 20 to rotate, which can improve the power transmission efficiency of the driving member 31 and improve the stability of the power transmission of the driving mechanism 30, thereby making the movement of the handle 20 more accurate and controllable.

[0053] Optionally, in combination with Figure 4 and Figure 6 As shown, the gear set 32 includes a first gear 321 and a second gear 322, the first gear 321 is coaxially driven with the handle 20; the second gear 322 is coaxially driven with the driving member 31, and the second gear 322 is in driving connection with the first gear 321; wherein the driving member 31 drives the second gear 322 to rotate to drive the first gear 321 to rotate, thereby driving the handle 20 to move between the hidden position and the hovering position.

[0054] The first gear 321 is coaxially driven with the handle 20, and the second gear 322 is coaxially driven with the driving member 31, which can shorten the force transmission path and reduce energy loss in the transmission process, thereby improving the utilization efficiency of the force. Through the driving connection of the second gear 322 and the first gear 321, the movement of the handle 20 can be accurately controlled. The driving member 31 drives the second gear 322 to rotate, and then drives the first gear 321 and the handle 20 to rotate, so that the control of the driving mechanism 30 on the rotation speed and direction of the handle 20 is more precise.

[0055] Optionally, in combination with Figure 4 As shown, the driving mechanism 30 further includes a first rotating shaft 33 and a second rotating shaft 34, the handle 20 and the first gear 321 are coaxially driven through the first rotating shaft 33, and the driving member 31 and the second gear 322 are coaxially driven through the second rotating shaft 34.

[0056] The first rotating shaft 33 can directly transmit driving force from the first gear 321 to the handle 20, and the second rotating shaft 34 can directly transmit driving force from the driving member 31 to the second gear 322. This direct transmission can reduce power loss and improve the movement synchronization between the first gear 321 and the handle 20 and between the driving member 31 and the second gear 322.

[0057] Optionally, the driving member 31 is a motor.

[0058] The motor can drive the handle 20 from the hidden position toward the hovering position by rotating in the forward direction. When the handle 20 reaches the hovering position, the motor stops rotating, and the gears of the gear set 32 ​​are engaged to maintain the handle 20 in the hovering position. The motor can drive the handle 20 from the hidden position toward the hidden position by rotating in the reverse direction. If the driving member 31 is a motor, the second rotating shaft 34 can be the output shaft of the motor.

[0059] Optionally, combined Figure 4 and Figure 6 As shown, the gear set 32 ​​further includes a third gear 323 . The third gear 323 is disposed between the first gear 321 and the second gear 322 , and the third gear 323 is meshed with both the first gear 321 and the second gear 322 .

[0060] The third gear 323 meshes with both the first gear 321 and the second gear 322. The third gear 323 acts as a transition gear, effectively transferring the driving force from the second gear 322 to the first gear 321. By introducing the third gear 323, the gear ratio of the gear set 32 ​​can be adjusted, thereby changing the rotational speed and torque of the handle 20. At the same time, by adding the third gear 323, the radial dimension of the gear set 32 ​​can be adjusted, allowing the gear set 32 ​​to better adapt to the installation position of the handle 20 and the drive member 31, thereby improving the coordination of the handle assembly. The coordinated use of the first gear 321, the second gear 322, and the third gear 323 can also increase the rigidity of the gear set 32, reduce gear deformation under high load conditions, and improve the durability and reliability of the gears.

[0061] Optionally, combined Figure 4 and Figure 6 As shown, the third gear 323 extends along the driving member 31 toward the handle 20 .

[0062] The first gear 321 is coaxial with the handle 20, the second gear 322 is coaxial with the driver 31, and the third gear 323 meshes with both the first and second gears 321, 322, allowing for adjustment of the axial length of the gear set 32. This reduces the length of the first rotating shaft 33 or the second rotating shaft 34, improving transmission efficiency. If the driver 31 is a motor, extending the third gear 323 along the driver 31 toward the handle 20 reduces the length of the motor's output shaft, making the drive mechanism 30 easier to install.

[0063] Optionally, combined Figure 4 As shown, the handle assembly for the refrigeration equipment further includes a fixing bracket 35 , and the driving mechanism 30 is mounted on the embedded box 10 via the fixing bracket 35 .

[0064] The fixing frame 35 can provide additional support, improve the stability of the driving mechanism 30 in the embedded box 10, and reduce the displacement or damage of the driving mechanism 30 caused by vibration or external force.

[0065] Optionally, combined Figure 2 、 Figure 4 and Figure 7 As shown, a first opening 12 is provided on one side of the embedded box 10, and the driving member 31 corresponds to the first opening 12. The embedded box 10 also includes a first cover 13, which is covered at the first opening 12, and the first cover 13 can move relative to the first opening 12 to open or close the first opening 12.

[0066] After opening the first opening 12 through the first cover 13, the driver 31 can be exposed, making it easy to inspect or replace the driver 31. When maintenance or replacement is not required, the first cover 13 can close the first opening 12 to protect the driver 31 from damage such as dust and moisture, thereby extending the service life of the driver 31.

[0067] Optionally, the driving member 31 and the gear set 32 ​​are detachably connected.

[0068] The drive member 31 and the gear set 32 ​​are detachably connected, which simplifies the replacement process. In this way, there is no need to dismantle the entire drive mechanism 30, and only the damaged or updated parts need to be replaced, thereby improving maintenance efficiency.

[0069] Optionally, combined Figure 4 As shown, the handle assembly for the refrigeration equipment also includes a first reset member 40, which is arranged between the handle 20 and the embedded box 10. When the handle 20 moves from the hovering position toward the open position, the first reset member 40 is deformed to drive the handle 20 to reset to the hovering position.

[0070] Moving the handle 20 from the hovering position toward the open position opens the refrigeration appliance door 80. As the handle 20 moves from the hovering position toward the open position, the first return member 40 deforms. After the door is opened, the handle 20 is released, and the deforming force of the first return member 40 automatically returns the handle 20 to the hovering position. This eliminates the need for manual reset and improves ease of use. After the handle 20 returns to the hovering position, the drive member 31 drives the gear train 32 to return the handle 20 to the hidden position.

[0071] Optionally, combined Figure 4 As shown, the first restoring member 40 is a torsion spring, one end of the torsion spring abuts against the handle 20 , and the other end of the torsion spring abuts against the embedded box 10 .

[0072] The torsion spring's smoother deformation and return motion can reduce noise and vibration during the movement of the handle 20, thereby improving the reliability of the handle assembly and preventing unusual noise. The torsion spring's smooth return motion can also improve operational efficiency, reducing user waiting time when operating the handle 20. It is understood that the first return member 40 can also be a compression spring.

[0073] Optionally, combined Figure 4 As shown, the handle assembly further includes a third transmission shaft, the torsion spring is sleeved on the outside of the third transmission shaft, and the torsion spring can rotate relative to the third transmission shaft.

[0074] The third transmission shaft provides stable support for the torsion spring, enhancing its stability during deformation and reset, and reducing errors caused by spring deformation. Furthermore, the torsion spring's placement outside the third transmission shaft optimizes spatial layout, making the entire handle assembly more compact.

[0075] Optionally, combined Figure 4 As shown, the handle assembly for refrigeration equipment further includes a damping mechanism 50 . The damping mechanism 50 is provided between the handle 20 and the embedded box 10 to adjust the movement speed of the handle 20 .

[0076] The damping mechanism 50 is located between the handle 20 and the embedded box 10. It allows the handle 20 to move slowly from the hidden position to the open position, and also allows the handle 20 to return slowly from the open position to the hidden position. This prevents collision between the handle 20 and the embedded box 10, improving the smoothness and service life of the system. The movement of the handle 20 from the open position to the hidden position consists of two stages: the first stage is the movement of the handle 20 from the open position to the hovering position, and the second stage is the movement of the handle 20 from the hovering position to the hidden position. The damping mechanism 50 provides damping during both stages of the handle 20's movement.

[0077] Optionally, combined Figure 4 As shown, the damping mechanism 50 includes a first damper 51 and a second damper 52. The first damper 51 is fixedly connected to the handle 20 and can rotate relative to the embedded box 10; the second damper 52 is sleeved on the outside of the first damper 51, and the second damper 52 is fixedly connected to the embedded box 10, and the first damper 51 can rotate relative to the second damper 52.

[0078] The first damper 51 is fixedly connected to the handle 20. When the handle 20 rotates, the first damper 51 rotates with the handle 20. The second damper 52 is fixedly connected to the embedded box 10. When the handle 20 rotates, the second damper 52 does not rotate with the handle 20 and remains fixed. Therefore, when the handle 20 rotates, the first damper 51 and the second damper 52 rotate relative to each other. The friction between the first damper 51 and the second damper 52 creates a damping effect, making the rotation process of the handle 20 smoother. This ensures that the entire movement of the handle 20 remains smooth, preventing the movement from being too fast or too slow, thereby reducing collisions or wear on the handle 20. At the same time, the sleeve structure of the first damper 51 and the second damper 52 can improve the structural compactness of the damping mechanism 50 and reduce the installation space 11 occupied.

[0079] Optionally, combined Figure 4 As shown, when the handle assembly includes the third rotating shaft 41 , the first damper 51 is sleeved on the outside of the third rotating shaft 41 , and the first damper 51 can rotate relative to the third rotating shaft 41 .

[0080] The third rotating shaft 41 provides support for the first damper 51, improving its stability and reducing errors caused by shaking or displacement of the first damper 51. Furthermore, the third rotating shaft 41 provides a clear rotation axis for the first damper 51, enhancing the rotational accuracy of the first damper 51. A torsion spring and the first damper 51 are mounted on the outer side of the third rotating shaft 41, allowing them to rotate coaxially and improving the handle's rotational efficiency.

[0081] Optionally, the handle assembly for the refrigeration appliance further includes a clutch mechanism, which is provided between the driving mechanism 30 and the handle 20 and is used to control the connection or disconnection between the driving mechanism 30 and the handle 20 .

[0082] By providing a clutch mechanism between the drive mechanism 30 and the handle 20, the two can be connected or disconnected as needed. When the handle 20 moves from the concealed position to the hovering position, the clutch mechanism connects the drive mechanism 30 and handle 20, allowing the drive mechanism 30 to transmit driving force to the handle 20, driving the handle 20 to move. When the handle 20 is pushed from the hovering position to the open position, the clutch mechanism disconnects the drive mechanism 30 from the handle 20, preventing the rotational force of the handle 20 from being transmitted to the drive mechanism 30. This reduces reverse impacts on the drive mechanism 30, protects the drive mechanism 30, and extends its service life.

[0083] Optionally, combined Figure 2 and Figure 5As shown, the handle assembly for the refrigeration equipment further comprises a power-assisted assembly 60, which is arranged in the embedded box 10 and corresponds to the handle 20, and the power-assisted assembly 60 can move relative to the embedded box 10 between a power-assisted position extending out of the embedded box 10 and a retracted position at least partially retracted into the embedded box 10; wherein when the handle 20 moves towards the open position, the power-assisted assembly 60 can be driven to move towards the power-assisted position.

[0084] The handle assembly is installed on the door body 80 of the refrigeration equipment, and when the power-assisted assembly 60 is in the power-assisted position extending out of the embedded box 10, the power-assisted assembly 60 can abut against the door body 80 of the refrigeration equipment, and the handle 20 can open the door by the lever principle, thereby having the function of saving labor in opening the door. With the assistance of the power-assisted assembly 60, the force required to open the door is reduced, and the opening efficiency of the door can be effectively improved. When the power-assisted assembly 60 is in the retracted position at least partially retracted into the embedded box 10, the power-assisted assembly 60 can avoid affecting the normal closing of the door body 80, thereby improving the sealing performance of the door body 80 when closing. The power-assisted assembly 60 is arranged corresponding to the handle 20, and when the handle 20 moves towards the open position, the handle 20 can cooperate with the power-assisted assembly 60 to drive the power-assisted assembly 60 to move towards the power-assisted position. During the movement of the handle 20 from the hidden position to the hovering position, the power-assisted assembly 60 is still in the retracted position. During the movement of the handle 20 from the hovering position to the open position, the power-assisted assembly 60 moves from the retracted position to the power-assisted position.

[0085] When the handle assembly provided by the embodiments of the present disclosure is installed on the door body 80 of the refrigeration equipment, the door can be opened by the lever principle, and at the same time, the design of the hidden handle 20 can reduce the space occupied by the handle 20 and increase the function of opening the door with assistance. In this way, the problems of difficult opening of the door by the user due to negative pressure and the problem of space occupation of the handle 20 of the refrigeration equipment can be solved.

[0086] Optionally, in combination with Figure 5 As shown, the power-assisted assembly 60 comprises a connecting rod assembly 61 and a push rod assembly 62, the connecting rod assembly 61 is arranged in the embedded box 10 and movably connected with the embedded box 10, and the connecting rod assembly 61 can be driven by the handle 20; the push rod assembly 62 is arranged in the embedded box 10 and driven by the connecting rod assembly 61; wherein when the handle 20 moves towards the open position, the handle 20 can drive the connecting rod assembly 61 to move, thereby driving the push rod assembly 62 to move towards the power-assisted position.

[0087] When the handle 20 moves from the hovering position towards the open position, the handle 20 drives the connecting rod assembly 61 to move, and the connecting rod assembly 61 drives the push rod assembly 62 to move from the retracted position to the power-assisted position, thereby assisting in opening the door.

[0088] Optionally, in combination with Figure 5As shown, the handle assembly for the refrigeration equipment also includes a second reset member 70, which is arranged between the power-assisting assembly 60 and the embedded box 10, and when the power-assisting assembly 60 moves toward the power-assisting position, the second reset member 70 is deformed to drive the power-assisting assembly 60 to reset to the retracted position.

[0089] The assist assembly 60 moves from the retracted position to the assist position, assisting in opening the refrigeration appliance door 80. As the assist assembly 60 moves from the retracted position to the assist position, the second return member 70 deforms. The deformation force of the second return member 70 automatically returns the assist assembly 60 to the retracted position. The second return member 70 can be an elastic structure such as a tension spring or a compression spring.

[0090] Optionally, combined Figure 5 As shown, the second restoring member 70 is connected between the connecting rod assembly 61 and the embedded box 10 .

[0091] As the connecting rod assembly 61 drives the push rod assembly 62 toward the assist position, the second reset member 70 deforms. The deformation force of the second reset member 70 resets the connecting rod assembly 61. After the connecting rod assembly 61 is reset, the push rod assembly 62, driven by the connecting rod assembly 61, returns to the retracted position. Connecting the second reset member 70 between the connecting rod assembly 61 and the embedded box 10 reduces the reset force required, thereby improving the reset efficiency of the assist assembly 60.

[0092] An embodiment of the present disclosure provides a refrigeration device, including a door body 80 and a handle assembly for the refrigeration device as described in any one of the above disclosed embodiments. The door body 80 is provided with a mounting groove 81; the embedded box 10 is provided in the mounting groove 81.

[0093] The refrigeration device provided by the embodiment of the present disclosure includes the handle assembly for refrigeration device described in any one of the above disclosed embodiments, and thus has all the beneficial effects of the handle assembly for refrigeration device described in any one of the above disclosed embodiments, which will not be repeated here.

[0094] Optionally, the door body 80 includes a side panel 82 and a second cover body, the side panel 82 is provided with a second opening, the second opening is communicated with the mounting groove 81, the driving member 31 is arranged toward the side panel 82, and the second opening corresponds to the driving member 31; the second cover body is covered at the second opening, and the second cover body can move relative to the second opening to open or close the second opening.

[0095] Combine Figure 1 and Figure 2As shown, the driver 31 is positioned toward the side panel 82. The second opening of the side panel 82 corresponds to the driver 31. Opening the second opening through the second cover allows for easy access to the driver 31 for repair or replacement. If the embedded box 10 is provided with a first opening 12, the first opening 12 and the first cover 13 correspond to the second opening. During maintenance, the driver 31 and gear assembly 32 can be disassembled by opening the second cover of the side panel 82 and then the first cover 13. This improves the ease with which the driver 31 can be disassembled and repaired. The second opening provided on the side panel 82 not only facilitates repair but also enhances the aesthetics.

[0096] Optionally, combined Figure 1 and Figure 2 As shown, the door body 80 further includes a front panel 83 connected to the side panel. The front panel 83 is provided with a third opening, which is communicated with the mounting groove 81 , and the handle 20 is provided at the third opening.

[0097] The handle 20 is arranged at the front panel 83 so that the handle 20 is hidden in the front of the door body 80 of the refrigeration appliance. This makes it easier for the user to grasp and operate the handle 20 during normal use, thereby improving the convenience of use.

[0098] Optionally, the refrigeration equipment also includes a sensor 90 and a controller. The sensor 90 is arranged on the handle assembly or the door body 80 for detecting door opening and closing information; the controller is connected to the sensor 90 and the drive mechanism 30 and is configured to control the operation of the drive mechanism 30 according to the detection information of the sensor 90.

[0099] This application takes the sensor 90 as an example of being provided on the handle assembly. Figure 3 and Figure 7 As shown, the sensor 90 is provided in the embedded box 10 .

[0100] Detecting door opening and closing information includes detecting door opening information and detecting door closing information. Detecting door opening information may be detecting a preset door opening action. When the sensor 90 recognizes that the user makes an action consistent with the preset door opening action, the controller confirms that the user needs to open the door. Detecting door opening information may also be detecting the distance between the user and the refrigeration device. When the sensor 90 detects that the distance between the user and the refrigeration device is less than a preset distance, the controller determines that the user needs to open the door. Detecting door closing information may be detecting the closing status of the door body 80, or may be detecting the distance between the user and the refrigeration device. When the sensor 90 detects that the door body 80 is closed, or detects that the distance between the user and the refrigeration device is greater than a preset distance, the controller determines that the door body 80 is closed. The sensor 90 may be an infrared sensor 90, a radio frequency identification sensor 90, a ranging sensor 90, a camera or other identification device.

[0101] After the sensor 90 detects the user opening the door, the controller controls the drive mechanism 30 to move the handle 20 from the hidden position toward the hovering position, causing the handle 20 to protrude from the outside of the door body 80. The user can then open the door body 80 using the handle 20. After the sensor 90 detects the user closing the door, the controller controls the drive mechanism 30 to move the handle 20 from the hovering position toward the hidden position. The disclosed embodiment integrates the sensor 90 and the controller, utilizing a human body sensing and drive method to achieve intelligent control of the handle assembly, improving the automation and convenience of door opening.

[0102] For example, when the sensor 90 detects door opening information, the motor is controlled to rotate forward, and the motor drives the gear set 32 ​​to rotate, so that the gear set 32 ​​drives the handle 20 to rotate synchronously. When the handle 20 rotates from the hidden position to the hovering position, the motor stops rotating. Due to the meshing state of the gears in the gear set 32, the handle 20 can remain in the hovering state. At this time, the handle 20 pops out of the door body 80, and the user pulls one end of the handle 20 to push the handle 20 to the open position, and the lever transmission can achieve power-assisted door opening. When the user completes the door opening action and releases the handle 20, the handle 20 returns from the open position to the hovering position under the action of the first reset member 40. The motor then rotates in the opposite direction, driving the gear set 32 ​​to drive the handle 20 back to the hidden position.
