DETAILED DESCRIPTION
[0026] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.
[0027] Refrigerators are important appliances that are indispensable for food storage in daily life. For most people, refrigerators are not only containers for storing food, but also important decorations in the home. Therefore, many people have high requirements for the appearance of refrigerators when purchasing them. Among them, refrigerators with upper and lower door structures usually have a larger gap between the upper and lower doors in order to reserve space for handles. Hidden handles are designed on the lower trim of the upper door and the upper trim of the lower door, respectively, so that users can open the refrigerator with hidden handles. However, if the gap between the upper and lower doors of the refrigerator is too large, the overall appearance of the refrigerator will not be good.
[0028] To solve the problem of large gap between the upper and lower doors of the refrigerator, refer to Figure 1The present application provides a scissor-type hidden door handle assembly, including: a refrigerator door 1, which is hinged to a box body 4; a lower decorative strip 2 is provided at the bottom end of the refrigerator door 1; a groove 21 is provided at one end of the lower decorative strip 2, and the groove 21 is connected to a door handle 3; the door handle 3 includes a scissor-type bracket 31, a door handle cover 32, and a motor 33; the scissor-type bracket 31 includes a first support rod 311 and a second support rod 312; the first support rod 311 and the second support rod 312 are hinged to form an X-shaped structure; one end of the first support rod 311 is connected to the door handle cover 32, the other end of the first support rod 311 is connected to the motor 33, one end of the second support rod 312 is connected to the door handle cover 32, and the other end of the second support rod 312 is connected to the lower decorative strip 2.
[0029] Among them, the lower decorative strip 2 is installed at the bottom end of the refrigerator door 1, and one end of the lower decorative strip 2 is provided with a groove 21 structure for accommodating the door handle 3. The groove 21 is provided with a hole on the side away from the frame of the refrigerator door 1, and the motor 33 is arranged in the hole. Then, after the scissors bracket 31 is connected with the groove 21, the door handle cover 32 and the motor 33, the scissors bracket 31 can be driven by the motor 33 to control the lifting and lowering of the door handle cover 32.
[0030] The scissor bracket 31 is formed by hingedly connecting two sets of symmetrically arranged first support rods 311 and second support rods 312. The scissor structure is a special mechanical structure that realizes vertical lifting movement through two sets of parallel and staggered scissors, so that the door handle cover 32 can stay at different heights. The working principle of the scissor structure is based on the balance of force and the principle of leverage. Specifically, when the door handle cover 32 needs to be lifted or lowered, the two sets of scissor arms are driven by an electric motor to move up and down alternately, thereby realizing the lifting and lowering of the entire door handle cover 32.
[0031] It is understandable that the present application can control the motor 33 by setting a sensor. For example, an infrared sensor is set, and when the user's hand is a certain distance away from the door handle cover 32, the sensor can send a signal to control the motor 33 to drive the scissor bracket 31 to retract, so that the door handle cover 32 moves perpendicular to the refrigerator door 1 toward the box body 4, so that the user can put his hand into the groove 21 to open the refrigerator door 1.
[0032] In some embodiments, Figure 3As shown, the lower decorative strip 2 also includes a rotating shaft 211, which is symmetrically arranged on both sides of the groove 21, and the second support rod 312 is rotatably connected to the groove 21 through the rotating shaft 211. The rotating shaft 211 is a cylindrical structure protruding from both sides of the groove 21, and a through hole is arranged at one end of the second support rod 312. After the rotating shaft 211 is inserted into the through hole, one end of the second support rod 312 can rotate around the rotating shaft 211. In order to reduce the second support rod 312 from falling off the rotating shaft 211, a nut can be installed at one end of the rotating shaft 211 after the rotating shaft 211 is inserted into the through hole, and the second support rod 312 is clamped by the nut and the side of the groove 21.
[0033] In some embodiments, Figure 2 As shown, the motor 33 includes a push rod 34, which is connected to the output shaft of the motor 33; and the push rod 34 is rotatably connected to the first support rod 311. The push rod 34 is a T-shaped structure, the vertical rod in the push rod 34 is connected to the output shaft of the motor 33, and the cross rod of the push rod 34 passes through the symmetrically arranged first support rods 311, so that the first support rod 311 can rotate around the push rod 34. When the motor 33 drives the push rod 34 to move, the first support rod 311 will move with the movement of the push rod 34. By setting the push rod 34, it is convenient for the motor 33 to simultaneously control the two first support rods 311 arranged in parallel, thereby facilitating the control of the scissor support 31.
[0034] In some embodiments, Figure 3 As shown, the groove 21 further includes a limiting claw 212, and the door handle cover 32 further includes a limiting block 321; the limiting claw 212 is engaged with the limiting block 321. When the door handle cover 32 moves toward the box body 4, the limiting claw 212 is separated from the limiting block 321, and when the door handle cover 32 moves to the side away from the box body 4, the phase claw and the phase block approach each other, and when the door handle cover 32 is flush with the outer surface of the refrigerator door 1, the limiting claw 212 is engaged with the limiting block 321. By setting the limiting block 321 and the limiting claw 212, the door handle cover 32 can be prevented from protruding from the outer surface of the refrigerator door 1.
[0035] In the process of the door handle cover 32 moving up and down, in order to ensure the stability of the door handle cover 32 moving process, in some embodiments, such as Figure 2 As shown, the limiting strips 322 are symmetrically arranged on both sides of the limiting block 321, the limiting strips 322 are perpendicular to the limiting block 321, and the distance between the two limiting strips 322 is greater than the length of the limiting claw 212. When the door handle cover 32 moves up and down, the symmetrically arranged limiting strips 322 can provide constraints for the movement of the door handle cover 32, thereby reducing the shaking of the door handle cover 32 when it moves.
[0036] In some embodiments, Figure 2As shown, the door handle cover 32 is a rectangular structure, the door handle cover 32 is provided with a flange structure, the flange structure is provided with a rolling shaft 323, the first support rod 311 is rotatably connected to the door handle cover 32 through the rolling shaft 323, and the second support rod 312 is slidably connected to the door handle cover 32 through the rolling shaft 323. When the motor 33 drives the push rod 34 to move, the first support rod 311 will move with the left and right movement of the push rod 34. Since the first support rod 311 and the second support rod 312 are hinged, during the left and right movement of the end of the first support rod 311 connected to the push rod 34, the other end of the first support rod 311 will move up and down, thereby driving the end of the second support rod 312 connected to the door handle cover 32 to move up and down. The distance between the first support rod 311 and the end of the second support rod 312 connected to the door handle cover 32 will change during the up and down movement, so the second support rod 312 is slidably connected to the door handle cover 32 through the rolling shaft 323. For example, a slide rail can be set on the flange structure, and the rolling shaft 323 can be inserted into the slide rail so that the rolling shaft 323 can slide in the slide rail. Then, after the second support rod 312 is connected to the rolling shaft 323, the second support rod 312 drives the rolling shaft 323 to slide in the slide rail.
[0037] In some embodiments, the door handle cover 32 is in the same plane as the outer surface of the refrigerator door 1. Setting the door handle cover 32 and the outer surface of the refrigerator door 1 in the same plane not only makes the door handle cover 32 and the outer surface of the refrigerator door 1 integrated, improving the overall aesthetics, but also can prevent the door handle cover 32 from causing harm to the human body when accidentally touched.
[0038] In some embodiments, a door handle is provided at one end of the lower decorative strip 2 close to the refrigerator door 1, and the door handle is a rectangular structure concave inward. The door handle is arranged along the horizontal direction of the refrigerator door 1, and the user puts his hand into the door handle, which is convenient for the user to exert force to open the refrigerator door 1.
[0039] In some embodiments, see Figure 4The present application provides a refrigerator, comprising a box body 4 and a scissor-type hidden door handle assembly provided in the above embodiment, wherein the scissor-type hidden door handle assembly is connected to the box body 4. By connecting the scissor-type hidden door handle assembly to the box body 4, the gap between the refrigerator doors 1 can be reduced. During use, the sensor senses whether a user touches the door handle cover 32. When the sensor senses the user, the motor 33 can be controlled to drive the push rod 34 to retract. The scissor bracket 31 moves in the direction of the motor 33 under the traction of the push rod 34, and the door handle cover 32 moves toward one side of the box body 4 in a direction perpendicular to the door body, so that the door handle cover 32 is recessed into the refrigerator door 1, thereby exposing the door handle. The user can put his hand into the door handle to open the refrigerator door 1. When the user closes the refrigerator door 1, the sensor can control the motor 33 to drive the push rod 34 to be pushed out. The scissor bracket 31 moves in the opposite direction of the motor 33 under the push of the push rod 34, and the door handle cover 32 moves to the opposite side of the box body 4 along the direction perpendicular to the door body until the door handle cover 32 is flush with the outer surface of the refrigerator door 1, so that the outer surface of the refrigerator door 1 remains flat.
[0040] It can be seen from the above technical scheme that the present application provides a scissor-type hidden door handle assembly and a refrigerator, and the scissor-type hidden door handle assembly includes: a refrigerator door 1, which is hinged to a box body 4; a lower decorative strip 2 is provided at the bottom end of the refrigerator door 1; a groove 21 is provided at one end of the lower decorative strip 2, and the groove 21 is connected to the door handle 3; the door handle 3 includes a scissor-type bracket 31, a door handle cover 32, and a motor 33; the scissor-type bracket 31 includes a first support rod 311 and a second support rod 312; the first support rod 311 and the second support rod 312 are hinged to form an X-shaped structure; one end of the first support rod 311 is connected to the door handle cover 32, the other end of the first support rod 311 is connected to the motor 33, one end of the second support rod 312 is connected to the door handle cover 32, and the other end of the second support rod 312 is connected to the lower decorative strip 2. When the user is sensed, the scissor bracket 31 moves in the direction of the motor 33 under the traction of the motor 33, and the door handle cover 32 moves toward the side of the cabinet 4 along the direction perpendicular to the refrigerator door 1, revealing the door handle position, so that the user can open the refrigerator door 1. When the user leaves, the scissor bracket 31 moves in the opposite direction of the motor 33 under the push of the motor 33, and the door handle cover 32 moves toward the side away from the cabinet 4 along the direction perpendicular to the refrigerator door 1 until the outer surface of the door handle cover 32 is flush with the outer surface of the refrigerator door 1. By setting the scissor-type hidden door handle, there is no need to reserve a gap between the upper and lower doors of the refrigerator, so as to solve the problem of large gap between the upper and lower doors of the refrigerator.
[0041] Similar parts between the embodiments provided in this application can be referenced to each other. The specific implementation methods provided above are only a few examples under the general concept of this application and do not constitute a limitation on the protection scope of this application. For those skilled in the art, any other implementation methods expanded based on the scheme of this application without creative work belong to the protection scope of this application.
