[0002] In order to prevent the cold air from leaking out, refrigerators usually use door seals to achieve a good sealing effect. This causes the door seals to have a large suction force, and a certain negative pressure will be formed in the refrigerator during refrigeration, so a large torque is required to open the door. Therefore, automatic door opening refrigerators are gradually becoming popular in the market. Automatic door opening of refrigerators mainly uses a movable push rod device to push the refrigerator door open. It is simple and practical, and is increasingly widely accepted.

[0003] However, due to the low temperature and high moisture content inside the refrigerator, the moisture will spread to the push rod device of the refrigerator after long-term use, reducing the service life of the push rod device. Utility Model Content

[0024] Preferably, the connecting rod group includes a second connecting rod, a third connecting rod and a first limiter, and the second connecting rod serves as an input end of the connecting rod group, and is used to drive the third connecting rod to move;

[0025] The first limiting member acts on the third connecting rod to limit the rotation of the third connecting rod relative to the second connecting rod and to enable the third connecting rod to move linearly along its extending direction.

[0026] In this solution, the connecting rod group is configured to include two connecting rods, which takes up little space and is convenient for adjusting the movement form; a first limiter is provided for the third connecting rod to limit the linear movement of the third connecting rod along its extension direction, thereby indirectly limiting the movement form of the shielding part, and the movement direction can be adjusted by replacing the first limiter as needed, with good adaptability.

[0057] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0058] Figure 1 The refrigerator push rod device of one embodiment of the utility model is a three-dimensional structure explosion diagram. As shown in the figure, the refrigerator push rod device includes a push rod assembly 10 and a shielding assembly 20. Figure 1In the figure, the right dashed box shows a part, namely the push rod assembly 10, and the left dashed box shows a part, namely the shielding assembly 20. The push rod assembly 10 includes a refrigerator push rod 11, which can be moved to a preset extended position to push open the refrigerator door, or moved to a retracted position to allow the door to be closed; the shielding assembly 20 includes a shielding portion 21 for shielding the push rod matching position, and the shielding portion 21 can be moved to a preset retracted position to expose the push rod matching position, or moved to a shielding position to shield the push rod matching position;

[0059] The shielding assembly 20 is connected to the push rod assembly 10, and when the shielding assembly 20 is in the retracted position, the push rod 11 is allowed to move to the extended position; when the push rod 11 is in the retracted position, the shielding portion 21 is allowed to move to the shielding position.

[0060] The utility model provides a shielding component 20 for the refrigerator push rod device, which can shield and protect the refrigerator push rod 11 and reduce the negative impact of factors such as water vapor on the function of the push rod 11, wherein the push rod component 10 and the shielding component 20 can respectively switch between the two states of pushing / retracting and retreating / shielding by moving; in addition, by connecting the push rod component 10 with the shielding component 20, and by setting the movement form of the push rod 11 and the shielding part 21, the shielding part 21 and the push rod 11 can not interfere with each other during the movement, the overall structure is more perfect, the shielding part 21 can be retreated to allow the push rod 11 to extend, and when the push rod 11 does not need to be extended, the shielding part 21 can be moved to the shielding position, and the integrity is better.

[0061] The connection method between the shielding assembly 20 and the push rod assembly 10 in this embodiment is as follows: Figure 1 , Figure 3 As shown, a connecting shaft is selected for connection. Accordingly, in order to realize the transmission and connection of the two components, the push rod assembly 10 includes a push rod transmission member, the push rod transmission member includes a first rotating wheel 12, and the first rotating wheel 12 serves as the input end of the push rod transmission member; the shielding assembly 20 includes a shielding part transmission member, the shielding part transmission member includes a second rotating wheel 22, and the second rotating wheel 22 serves as the input end of the shielding part transmission member.

[0062] For the shielding assembly 20 in this embodiment, the shielding part transmission member includes a first rotating wheel 12 and a second rotating wheel 22, and the two rotating wheels are respectively connected to the first connecting shaft 30 and rotate around the first connecting shaft 30. Figure 1 As shown, two white arrows are used to indicate the way in which the first connecting shaft 30 connects the two wheels. The first connecting shaft 30 is offset from the center of the second wheel 22, and the first connecting shaft 30 is connected to an external power source, such as a motor. The first connecting shaft 30 can be driven by the same power source, so that the two components can be controlled and linked synchronously at the same time, thereby achieving the effect of non-interference between the two components as before. In addition, the coaxial connection of the two wheels can make the overall device compact and occupy a small space.

[0063] The connection method using the connecting shaft provided in this embodiment is only for illustration. In the actual implementation process, those skilled in the art should understand that the connection method of the first connecting shaft 30 with the first rotating wheel 12 and the second rotating wheel 22 can be adjusted as needed, such as replacing the rotating wheel and the connecting shaft with a connecting rod, etc. Under the premise of not affecting the connection effect of the two components, the specific connection method adopted does not affect the protection scope of the present utility model.

[0064] Figure 2 This is a front perspective view of the refrigerator push rod device after assembly according to an embodiment of the utility model, that is, the effect view after the two components are connected by the first connecting shaft 30 as before. Among them, the push rod transmission member includes a cam 13, the rim of the cam 13 is connected to one end of the push rod 11, and the cam 13 is used as the output end of the push rod transmission member to rotate and drive the push rod 11 to move. The rim of the cam 13 is used to connect the push rod 11, so that the movement of the power source or other transmission members can be transmitted to the push rod 11, and the rotation of the cam 13 can be converted into the movement of the push rod 11 by the rim.

[0065] In this embodiment, the rim of the cam 13 pushes the push rod 11 to move in an abutting manner. In actual implementation, this connection method can be adjusted as needed, and the illustrated connection method is not intended to limit the protection scope of the present utility model.

[0066] like Figure 2 As shown, the push rod transmission member in this embodiment includes a second connecting shaft 14 connected to the cam 13, and the second connecting shaft 14 is used to drive the cam 13 to rotate, so as to control the rotation of the cam 13 and indirectly control the movement of the push rod 11.

[0067] The push rod transmission member also includes a third connecting shaft 15 connected to the cam 13. The third connecting shaft 15 is fixed to determine the rotation center of the cam 13. The third connecting shaft 15 and the second connecting shaft 14 are offset in the end surface direction of the cam 13 and are used to limit the rotation angle of the cam 13. In use, the positions of the two connecting shafts can be set according to needs to adjust the angle range of the cam 13 and indirectly adjust the moving distance of the push rod 11.

[0068] In this embodiment, the push rod transmission member further includes a first connecting rod 16, one end of which is connected to the first rotating wheel 12 and offset from the rotation center thereof, and the other end of which is connected to the second connecting shaft 14, connecting the aforementioned first rotating wheel 12 and the cam 13, and used to drive the second connecting shaft 14 to move. This connection method is suitable for the motion transmission between the two wheels, and the rotation speed and angle of the cam 13 can be properly adjusted by adjusting the connection position, and has good adaptability and is easy to adjust.

[0069] Depend on Figure 2It can be seen that, taking the above-mentioned push rod transmission member adopted in this embodiment as an example, when the first rotating wheel 12 rotates counterclockwise from 0-180 degrees, as the angle increases, the first connecting rod 16 can drive the cam 13 to rotate clockwise, and the clockwise movement amplitude of the cam 13 also increases, thereby further pushing the push rod 11 to move upward. The distance increases, and at this time, the limit block 17 limits the movement direction of the push rod 11. When the first rotating wheel 12 rotates counterclockwise to 180 degrees, the upward movement distance of the push rod 11 reaches the maximum value. Correspondingly, it can be known from the above-mentioned scheme that the first rotating wheel 12 and the second rotating wheel 22 are coaxially connected to the first connecting shaft 30 that when the first rotating wheel 12 rotates in the above-mentioned direction, the second rotating wheel simultaneously rotates counterclockwise from 0-180 degrees and drives the corresponding shielding part transmission member to move.

[0070] In addition, for the shielding assembly 20 in this embodiment, the shielding part transmission member includes a connecting rod group, which is the output end of the shielding part transmission member, connected between the shielding part 21 and the second rotating wheel 22, and is used to drive the shielding part 21 to move to the shielding position or the retracted position. This embodiment uses a connecting rod group as the transmission member of the shielding part 21, which can realize the setting of the shielding part 21 away from the second rotating wheel 22. Its structural restrictions are smaller, avoiding interference between the above two components. In the actual implementation process, a transmission member other than the connecting rod group can be used; in addition, the use of a transmission member can also transform the action form of the power source to adapt to the movement requirements.

[0071] like Figure 2 As shown, the connecting rod group includes a second connecting rod 23, a third connecting rod 24 and a first stopper 25. The connecting rod group is set as two connecting rods, which takes up little space and is convenient for adjusting the movement form. Among them, the second connecting rod 23 is used as the input end of the connecting rod group to drive the third connecting rod 24 to move; the first stopper 25 acts on the third connecting rod 24 to limit the rotation of the third connecting rod 24 relative to the second connecting rod 23, and makes the third connecting rod 24 move linearly along its extension direction, which indirectly limits the movement form of the shielding part 21, and in the actual implementation process, the movement direction can be adjusted by replacing the first stopper 25 as needed, which has good adaptability.

[0072] In this embodiment, the first limiting member 25 includes two limiting plates arranged opposite to each other, and the two limiting plates are used to enclose a limiting channel. The third connecting rod 24 is passed through the limiting channel. The two limiting plates are respectively located on the upper and lower sides of the third connecting rod 24 along the thickness direction, which is adapted to the structural characteristics of the connecting rod. The limiting structure is simple and easy to adjust.

[0073] In this embodiment, the shielding part transmission member also includes a second limit member 26, and the second limit member 26 includes a fixed hinged portion to limit the movement of the second connecting rod 23 to rotation. The hinged portion is hinged to the second connecting rod 23 and is away from the third connecting rod 24. The hinged portion can be fixed to the external refrigerator shell to make the movement of the entire connecting rod group more stable and the installation is more convenient. The second connecting rod 23 can swing around the hinged portion.

[0074] like Figure 4 As shown, in this embodiment, the shielding part transmission member also includes a third rotating wheel 27, the third rotating wheel 27 is connected to the second connecting rod 23, and abuts against the rim of the second rotating wheel 22, and the second rotating wheel 22 pushes the third rotating wheel 27 to move, so as to convert the rotational movement of the second rotating wheel 22 into a push on the second connecting rod 23 through the abutment of the rim, thereby driving the second connecting rod 23 to swing, which adapts to the effect of the second connecting rod 23 swinging around the second limit member 2 in the aforementioned scheme.

[0075] In this embodiment, the push rod assembly 10 also includes a limit block 17, which is fixed and has a push rod channel inside. The push rod 11 passes through the push rod channel and can slide axially, thereby limiting the movement of the push rod 11 in the push rod channel and making the movement effect more stable.

[0076] Depend on Figure 2 It can be seen that, taking the above-mentioned shielding part transmission member adopted in this embodiment as an example, when the second rotating wheel 22 rotates counterclockwise from 0-180 degrees, the second connecting rod 23 swings to the left to the maximum amplitude, and the second rotating wheel 22 drives the third rotating wheel 27 to rotate, and further drives the second connecting rod 23 to swing to the left, wherein the third rotating wheel 27 transmits power and reduces friction. When the second connecting rod 23 swings to the left, it drives the third connecting rod 24 to move to the left, and the first limiting member 25 limits the movement direction of the third connecting rod 24. Further, the third connecting rod 24 drives the shielding part 21 to move to the left to the maximum displacement.

[0077] Here, the present invention provides an exemplary description of the manner in which the push rod 11 in the refrigerator push rod device of the present embodiment is moved to the retracted position. The following two manners are only used as references for implementation or adjustment of the present embodiment:

[0078] ① Move in the opposite direction of the above transmission parts, that is, the first connecting shaft 30 is reversed, and at the same time, the first rotating wheel 12 and the second rotating wheel 22 rotate clockwise to the original 0 degree position, and further, the cam 13 rotates counterclockwise to the original 0 degree position, at which time the push rod 11 and the shielding part 21 are reset;

[0079] ② Continue to move in the same direction as the above transmission parts, that is, the first rotating wheel 12 and the second rotating wheel 22 rotate counterclockwise from 180-360 degrees, that is, rotate the second half of a circle, and the same reset effect as in ① can also be achieved.

[0080] Those skilled in the art should understand that the push rod transmission member, the shielding portion transmission member and their movement modes selected in this embodiment are illustrative examples of preferred solutions and are for reference only, and are not intended to limit the scope of protection of the present utility model.

[0081] In the description of the present utility model, the selected embodiment is one of the specific implementation methods within the protection scope defined by the attached claims, which is only used as an example. The protection scope of the present utility model shall be based on the definition of the claims.

[0082] Those skilled in the art may make various adjustments to the implementation methods thereof without departing from the principles and essence of the present invention. The above-mentioned exemplified adjusted implementation methods all fall within the protection scope of the present invention and will not result in the loss of key technical effects.
