为提高门体开闭过程的自动化程度,可以在冰箱上安装开闭机构。由于门体的开闭过程需要克服门封条吸力等多个作用力做功,因此往往需要配置多个不同的开闭机构进行联合作用才能顺利地开闭门体,而这会导致开闭机构数量冗杂,整体结构复杂,集成性差,占用空间大,且需要在发泡过程中预留出各个机构的安装空间,导致发泡过程复杂。In order to improve the automation degree of the door opening and closing process, an opening and closing mechanism can be installed on the refrigerator. Since the opening and closing process of the door body needs to overcome multiple forces such as the suction force of the door seal, it is often necessary to configure multiple different opening and closing mechanisms for joint action to smoothly open and close the door body, which will lead to a complex number of opening and closing mechanisms. , the overall structure is complex, the integration is poor, the space is large, and the installation space of each mechanism needs to be reserved during the foaming process, resulting in a complex foaming process.
因此,如何利用集成化的开闭机构改进冰箱的门体开闭方法,在简化开闭机构的结构的前提下提高门体开闭过程的自动化程度,成为本领域技术人员亟待解决的技术问题。Therefore, how to use the integrated opening and closing mechanism to improve the door opening and closing method of the refrigerator, and improve the automation degree of the door opening and closing process under the premise of simplifying the structure of the opening and closing mechanism, has become a technical problem to be solved urgently by those skilled in the art.

The door closing action and the beam body turning action can be completed, so that the refrigerator of the present invention can adjust the automatic opening and closing of the door body by simple control logic.

具体实施方式Detailed ways
图1是根据本发明一个实施例的冰箱10的示意图。冰箱10一般性地可包括箱体110、门体120、翻转梁140(以下可简称“梁体”)、开闭机构200、翻转机构500和控制装置。开闭机构200和翻转机构500可以组成冰箱10的自动开关门装置。其中开闭机构200用于驱动门体120在打开位置和关闭位置之间往复转动。翻转机构500用于驱动翻转梁140在翻折位置和舒展位置之间翻转。本实施例的冰箱10可以为单门冰箱10,或者可以为至少具有两个开启方向相对设置的门体120的多门冰箱10,例如对开门冰箱10、十字门冰箱10、法式多门冰箱10等。FIG. 1 is a schematic diagram of a refrigerator 10 according to one embodiment of the present invention. The refrigerator 10 may generally include a box body 110 , a door body 120 , a turning beam 140 (hereinafter referred to as a “beam body”), an opening and closing mechanism 200 , a turning mechanism 500 and a control device. The opening and closing mechanism 200 and the turning mechanism 500 may constitute an automatic door opening and closing device of the refrigerator 10 . The opening and closing mechanism 200 is used to drive the door body 120 to reciprocate between the open position and the closed position. The flip mechanism 500 is used to drive the flip beam 140 to flip between the folded position and the extended position. The refrigerator 10 in this embodiment may be a single-door refrigerator 10, or may be a multi-door refrigerator 10 having at least two door bodies 120 with opposite opening directions, such as a side-by-side refrigerator 10, a cross-door refrigerator 10, and a French multi-door refrigerator 10. Wait.
以下实施例将以对开门冰箱10为例,针对适用于对开门冰箱10的开闭机构200、翻转机构500、以及设置有上述开闭机构200、翻转机构500的对开门冰箱10的控制方法进行示例,本领域技术人员在了解本实施例的基础上,应当完全有能力针对其他应用情况进行拓展,此处不再一一示例。The following embodiments will take the side-by-side refrigerator 10 as an example to describe the control method of the side-by-side refrigerator 10 suitable for the opening and closing mechanism 200 , the turning mechanism 500 of the side-by-side refrigerator 10 , and the side-by-side refrigerator 10 provided with the above-mentioned opening and closing mechanism 200 and the turning mechanism 500 . For example, those skilled in the art should be fully capable of expanding for other application situations on the basis of understanding the present embodiment, which will not be illustrated one by one here.
箱体110内部可以形成有储物间室,储物间室可以为具有前向开口的储物空间。门体120可枢转地设置于箱体110,以封闭或打开前向开口,从而关闭或打开储物间室。本实施例的门体120可以为两个,镜像对称地设置于前向开口处,例如,第一门体120可以用于封闭前向开口的左半部分,第二门体120可以用于封闭前向开口的右半部分。两个门体120的打开方向相对,例如前述第一门体120的枢转轴可以位于其左侧,前述第二门体120的枢转轴可以位于其右侧。图1中箭头示出左右方向,其中“左”“右”等用于表示方位的词语,均是相对于冰箱10的实际使用状态而言的,大致可以为箱体110 的水平横向延伸方向。A storage compartment may be formed inside the box body 110 , and the storage compartment may be a storage space with a forward opening. The door body 120 is pivotally disposed on the box body 110 to close or open the front opening, thereby closing or opening the storage compartment. There may be two door bodies 120 in this embodiment, which are mirror-symmetrically disposed at the front opening. For example, the first door body 120 may be used to close the left half of the front opening, and the second door body 120 may be used to close the front opening. Right half of the forward opening. The opening directions of the two door bodies 120 are opposite, for example, the pivot axis of the first door body 120 may be located on the left side thereof, and the pivot axis of the second door body 120 may be located on the right side thereof. The arrows in FIG. 1 show the left-right direction, and words such as “left” and “right” used to indicate orientation are relative to the actual use state of the refrigerator 10 , and may be roughly the horizontal and lateral extension direction of the box 110 .
每一门体120分别具有各自的关闭位置和打开位置。当门体120处于关闭位置时,门体120封闭箱体110的前向开口,当门体120从关闭位置向打开位置转动时,门体120打开箱体110的前向开口。值得说明的是,门体120可以具有预设的一个打开位置,例如该打开位置与关闭位置之间的枢转角度可以为135°。门体120也可以具有多个预设不同的打开位置,每一打开位置相对于关闭位置的枢转角度可以不同,并且在开门过程中可以根据开门信号的指示选择性地驱动门体120转动至任一打开位置。每一打开位置相对于关闭位置的枢转角度影响门体120的打开程度。将门体120的打开位置预设为多个,并根据开门信号的指示选择打开位置,可使冰箱10根据用户的使用需求调整门体120的打开程度,从而可以减少开门状态下的冷量散失。Each door body 120 has a respective closed position and an open position, respectively. When the door body 120 is in the closed position, the door body 120 closes the front opening of the box body 110 , and when the door body 120 is rotated from the closed position to the open position, the door body 120 opens the frontward opening of the box body 110 . It is worth noting that the door body 120 may have a preset opening position, for example, the pivoting angle between the opening position and the closing position may be 135°. The door body 120 can also have a plurality of preset different opening positions, the pivot angle of each opening position relative to the closed position can be different, and during the door opening process, the door body 120 can be selectively driven to rotate according to the indication of the door opening signal. either open position. The pivoting angle of each open position relative to the closed position affects the degree of opening of the door body 120 . Presetting the opening positions of the door body 120 to a plurality of positions and selecting the opening positions according to the instructions of the door opening signal enables the refrigerator 10 to adjust the opening degree of the door body 120 according to the user's usage requirements, thereby reducing the loss of cooling capacity in the open state.
翻转梁140可以可翻转地连接于冰箱10的门体120。例如翻转梁140可以可翻转地连接至封闭前向开口左半部分的第一门体120,翻转梁140的第一端可以固定连接至第一门体120的右侧边缘部位,翻转梁140的第二端与第一端相对,且以第一端为转轴进行转动,从而实现翻转梁140的翻转。The inversion beam 140 may be reversibly connected to the door body 120 of the refrigerator 10 . For example, the inversion beam 140 may be reversibly connected to the first door body 120 closing the left half of the front opening, the first end of the inversion beam 140 may be fixedly connected to the right edge of the first door body 120, and the The second end is opposite to the first end, and rotates with the first end as the rotation axis, so as to realize the inversion of the inversion beam 140 .
翻转梁140和门体120均可以大致呈板状。翻转梁140可以根据门体120的开闭状态相对于门体120翻转。翻转梁140的翻转过程是实现门体120开闭的必要环节。当门体120处于关闭位置时,翻转梁140所在板面与门体120所在板面之间的夹角可以大致为0°,在门体120从关闭位置向打开位置转动的过程中,翻转梁140可以相对于门体120转动,使得翻转梁140所在板面与门体120所在板面之间的夹角可以大致为90°,此时翻转梁140相对于门体120转动至翻折位置;在门体120从打开位置转动至关闭位置的过程中,翻转梁140可以相对于门体120再次转动,使得翻转梁140所在板面与门体120所在板面之间的夹角恢复至0°,此时翻转梁140相对于门体120转动至舒展位置。Both the turning beam 140 and the door body 120 may be substantially plate-shaped. The inversion beam 140 may invert relative to the door body 120 according to the opening and closing state of the door body 120 . The inversion process of the inversion beam 140 is a necessary link for realizing the opening and closing of the door body 120 . When the door body 120 is in the closed position, the angle between the board surface where the flip beam 140 is located and the board surface where the door body 120 is located may be approximately 0°. During the rotation of the door body 120 from the closed position to the open position, the flip beam 140 can be rotated relative to the door body 120, so that the angle between the board surface where the flip beam 140 is located and the board surface where the door body 120 is located can be approximately 90°, at this time the flip beam 140 is rotated relative to the door body 120 to the folded position; During the rotation of the door body 120 from the open position to the closed position, the flip beam 140 can be rotated relative to the door body 120 again, so that the included angle between the board surface where the flip beam 140 is located and the board surface where the door body 120 is located returns to 0° , at this time, the turning beam 140 rotates to the extended position relative to the door body 120 .

图3是根据本发明一个实施例的冰箱10的控制方法的示意图。该控制方法一般性地可包括:FIG. 3 is a schematic diagram of a control method of the refrigerator 10 according to an embodiment of the present invention. The control method may generally include:
步骤S302,确定门体120处于关闭位置。Step S302, it is determined that the door body 120 is in the closed position.

步骤S306,控制顶杆260伸出以顶开门体120,并检测门体120相对于关闭位置的枢转角度。In step S306, the ejector rod 260 is controlled to extend to push up the door body 120, and the pivot angle of the door body 120 relative to the closed position is detected.
步骤S308,判断门体120相对于关闭位置的枢转角度是否大于预设的第一角度阈值。Step S308, determining whether the pivot angle of the door body 120 relative to the closed position is greater than a preset first angle threshold.
步骤S310,在门体120相对于关闭位置的枢转角度大于预设的第一角度阈值的情况下,控制导杆活动以带动门体120向打开位置转动。Step S310 , when the pivot angle of the door body 120 relative to the closed position is greater than the preset first angle threshold, control the guide rod to move to drive the door body 120 to rotate to the open position.
使用上述方法,本实施例的冰箱10在确定门体120处于关闭位置且获取到冰箱10的开门信号的情况下,通过控制顶杆260伸出以顶开门体120,并在门体120相对于关闭位置的枢转角度大于预设的第一角度阈值的情况下控制导杆活动以带动门体120向打开位置转动,从而可以顺利地完成开门动作。本实施例将顶杆260和导杆集成于开闭机构200,通过对开闭机构200的顶杆260和导杆进行控制,改进了冰箱10的门体120开闭方法,利用集成化的开闭机构200改进冰箱10的门体120开闭方法,在简化开闭机构200的结构的前提下提高门体120开闭过程的自动化程度。Using the above method, the refrigerator 10 of this embodiment controls the ejector rod 260 to extend to push up the door body 120 when the door body 120 is determined to be in the closed position and the door opening signal of the refrigerator 10 is obtained, and the door body 120 is opposite to the door body 120. When the pivot angle of the closed position is greater than the preset first angle threshold, the guide rod is controlled to move to drive the door body 120 to rotate to the open position, so that the door opening action can be completed smoothly. In this embodiment, the ejector rod 260 and the guide rod are integrated into the opening and closing mechanism 200. By controlling the ejector rod 260 and the guide rod of the opening and closing mechanism 200, the method for opening and closing the door 120 of the refrigerator 10 is improved. The closing mechanism 200 improves the opening and closing method of the door body 120 of the refrigerator 10 , and improves the automation degree of the opening and closing process of the door body 120 under the premise of simplifying the structure of the opening and closing mechanism 200 .
通过在顶杆260伸出以顶开门体120的过程中检测门体120相对于关闭位置的枢转角度,并根据枢转角度的大小控制导杆活动以带动门体120转动,使得本实施例的冰箱10能够利用顶杆260和导杆的有机配合,克服门封条吸力等多个作用力做功,实现门体120的自动开闭。By detecting the pivot angle of the door body 120 relative to the closed position when the ejector rod 260 is extended to push up the door body 120, and controlling the movement of the guide rod according to the pivot angle to drive the door body 120 to rotate, this embodiment makes The refrigerator 10 of the present invention can utilize the organic cooperation of the ejector rod 260 and the guide rod to overcome multiple forces such as the suction of the door seal and perform work, so as to realize the automatic opening and closing of the door body 120 .
上述步骤S302中,在确定门体120处于关闭位置的过程中,例如,可以获取冰箱10的开关门记录,开关门记录中依时间顺序记录有设定时间段内冰箱10每次执行的开门动作和关门动作,若开关门记录中此前最后一项记录对应于关门动作,则可以确定门体120处于关闭位置。In the above step S302, in the process of determining that the door body 120 is in the closed position, for example, the door opening and closing records of the refrigerator 10 can be obtained, and the door opening and closing records are recorded in chronological order with the door opening actions performed by the refrigerator 10 each time within the set time period. And the door closing action, if the previous last record in the door opening and closing record corresponds to the door closing action, it can be determined that the door body 120 is in the closed position.
在一些可选的实施例中,还可以针对确定门体120处于关闭位置的方法进行变换,例如箱体110内可以设置有用于提供照明光线的照明灯,通过检测照明灯的工作状态可以确定门体120处于关闭位置,但不限于此。照明灯的工作状态可以包括运行状态和关闭状态。门体120处于关闭位置时,照明灯可以处于关闭状态。门体120处于打开位置时,箱体110内的照明灯可以切换至运行状态,以向箱体110提供照明光线。In some optional embodiments, the method for determining that the door body 120 is in the closed position can also be changed. For example, an illumination lamp for providing illumination light can be provided in the box body 110, and the door can be determined by detecting the working state of the illumination lamp. The body 120 is in a closed position, but is not limited thereto. The working state of the lighting lamp can include a running state and an off state. When the door body 120 is in the closed position, the lighting lamp may be in an off state. When the door body 120 is in the open position, the lighting lamp in the box body 110 can be switched to a running state to provide lighting light to the box body 110 .
上述步骤S304中,开门信号用于指示冰箱10执行开门动作以打开门体120。开门信号的触发条件可以为冰箱10接收到用户发送的开门指令,该开门指令可以由用户通过语音发送到冰箱10的语音交互模块,冰箱10接收到开门指令后可以生成开门信号。开门信号中可以含有用于指示门体120转动至某一打开位置的信息。In the above step S304, the door opening signal is used to instruct the refrigerator 10 to perform the door opening action to open the door body 120. The trigger condition of the door opening signal may be that the refrigerator 10 receives the door opening command sent by the user, and the door opening command may be sent by the user to the voice interaction module of the refrigerator 10 by voice, and the refrigerator 10 may generate the door opening signal after receiving the door opening command. The door opening signal may contain information for instructing the door body 120 to rotate to a certain opening position.
上述步骤S306中,在控制顶杆260伸出以顶开门体120的步骤中,启动第二驱动电机216,以向顶杆260提供驱动力,从而驱动顶杆260伸出。第二驱动电机216可以通过第二传动组件连接至顶杆260。即,第二传动组件一方面可以连接至第二驱动电机216 的输出轴,另一方面可以连接至顶杆260。例如第二驱动电机216可以为步进电机,第二传动组件可以为齿轮组。In the above step S306 , in the step of controlling the ejector rod 260 to extend to push up the door body 120 , the second driving motor 216 is activated to provide driving force to the ejector rod 260 to drive the ejector rod 260 to extend. The second drive motor 216 may be connected to the jack 260 through a second transmission assembly. That is, the second transmission assembly can be connected to the output shaft of the second drive motor 216 on the one hand, and can be connected to the ejector rod 260 on the other hand. For example, the second driving motor 216 may be a stepper motor, and the second transmission component may be a gear set.
图4是图2所示开闭机构200的俯视图,为便于观察开闭机构200与门体120之间的相对位置,图4也示出了冰箱10的部分门体120以及部分箱体110。4 is a top view of the opening and closing mechanism 200 shown in FIG. 2 . In order to facilitate the observation of the relative position between the opening and closing mechanism 200 and the door body 120 , FIG. 4 also shows part of the door body 120 and part of the box body 110 of the refrigerator 10 .
本实施例的顶杆260可以大致呈长杆形状。在冰箱10箱体110的左右延伸方向上,顶杆260可以设置于导杆的右侧,且靠近门体120与翻转梁140相接的部位,以利用较小的作用力顶开门体120。The ejector rod 260 in this embodiment may be substantially in the shape of a long rod. In the left and right extension direction of the box 110 of the refrigerator 10 , the ejector rod 260 may be disposed on the right side of the guide rod, and close to the part where the door body 120 and the turning beam 140 are connected, so as to use a small force to eject the door body 120 .
顶杆260配置成沿其中心轴线方向受控地伸出或缩回,且顶杆260的中心轴线平行于冰箱10的前后延伸方向。图1箭头示出箱体110的前后延伸方向,其中“前”“后”等用于表示方位的词语,均是相对于冰箱10的实际使用状态而言的。The ejector bar 260 is configured to be controllably extended or retracted along the direction of its center axis, and the center axis of the ejector bar 260 is parallel to the front-rear extension direction of the refrigerator 10 . The arrows in FIG. 1 show the front and rear extension directions of the box body 110 , and words such as “front” and “rear” used to indicate orientation are all relative to the actual use state of the refrigerator 10 .
顶杆260上形成有沿其中心轴线方向排布的齿条261,用于与第二传动组件啮合连接,使得第二传动组件将第一驱动电机215的驱动力传递至顶杆260。A rack 261 is formed on the ejector rod 260 along the direction of its central axis for engaging with the second transmission assembly, so that the second transmission assembly transmits the driving force of the first driving motor 215 to the ejector rod 260 .
壳体230大致可以呈长方体形状,也可以为任意其他形状。壳体230的内部形成安装空间。开闭机构200设置于安装空间。开闭机构200集成设置于一壳体230。壳体230可以设置于箱体110上方,且与门体120的顶部靠近设置,以便于对门体120施加作用力。壳体230可以具有相对设置的前壁231和背壁232,前壁231上开设有供顶杆260插入其中且可伸缩活动的伸缩孔。The casing 230 can be roughly in the shape of a rectangular parallelepiped, and can also be in any other shape. The interior of the housing 230 forms an installation space. The opening and closing mechanism 200 is installed in the installation space. The opening and closing mechanism 200 is integrated in a casing 230 . The casing 230 may be disposed above the box body 110 and disposed close to the top of the door body 120 , so as to exert a force on the door body 120 . The housing 230 may have a front wall 231 and a back wall 232 disposed opposite to each other, and the front wall 231 is provided with a telescopic hole into which the ejector rod 260 can be inserted and telescopically movable.
图5是图4所示的开闭机构200的内部结构图。FIG. 5 is an internal configuration diagram of the opening and closing mechanism 200 shown in FIG. 4 .
顶杆260可以全部位于安装空间内,其前端也可以部分露出于前壁231外侧。顶杆260可以穿过伸缩孔向前伸出以顶开门体120。复位弹性件270可以连接于壳体230的背壁232与顶杆260之间。即,复位弹性件270沿顶杆260的中心轴线方向设置于顶杆260的后侧,且复位弹性件270的一端与顶杆260固定连接,另一端与壳体230的后壁固定连接。复位弹性件270的伸缩方向与顶杆260的中心轴线方向共线。在顶杆260向前伸出以顶开门体120的过程中,复位弹性件270产生拉伸形变。The top rod 260 may be entirely located in the installation space, and its front end may also be partially exposed outside the front wall 231 . The ejector rod 260 can extend forward through the telescopic hole to eject the door body 120 . The restoring elastic member 270 may be connected between the back wall 232 of the housing 230 and the top rod 260 . That is, the reset elastic member 270 is disposed on the rear side of the top rod 260 along the central axis direction of the top rod 260 , and one end of the reset elastic member 270 is fixedly connected to the top rod 260 , and the other end is fixedly connected to the rear wall of the housing 230 . The telescopic direction of the restoring elastic member 270 is collinear with the central axis direction of the ejector rod 260 . During the process that the ejector rod 260 extends forward to push up the door body 120 , the restoring elastic member 270 is stretched and deformed.
在控制顶杆260伸出以顶开门体120的步骤之后,且在导杆开始驱动门体120向打开位置转动之后,控制方法还包括:控制第二驱动电机216停机,使得复位弹性件270带动顶杆260缩回。也就是说,复位弹性件270配置成在顶杆260伸出以顶开门体120之后带动顶杆260缩回,以防顶杆260对门体120的关闭过程造成干涉。该复位弹性件270可以为具备伸缩性能的任意弹性体,例如弹簧,但不限于此。After the step of controlling the ejector rod 260 to extend to push up the door body 120, and after the guide rod starts to drive the door body 120 to rotate to the open position, the control method further includes: controlling the second driving motor 216 to stop, so that the reset elastic member 270 drives the The jack 260 is retracted. That is, the restoring elastic member 270 is configured to drive the ejector bar 260 to retract after the ejector bar 260 extends to push the door body 120 to prevent the ejector bar 260 from interfering with the closing process of the door body 120 . The restoring elastic member 270 may be any elastic body with stretchability, such as a spring, but is not limited thereto.
在一些实施例中,开闭机构200还可以包括接近传感器280,设置于顶杆260的齿条261的前侧。顶杆260做伸出运动时,其齿条261会随之前移。当顶杆260的齿条261抵压于接近传感器280时,接近传感器280可以产生特定的电信号,第二驱动电机216在接收到接近传感器280的电信号之后可以切换至停机状态。In some embodiments, the opening and closing mechanism 200 may further include a proximity sensor 280 disposed on the front side of the rack 261 of the ejector rod 260 . When the ejector rod 260 is extended, the rack 261 thereof will move forward. When the rack 261 of the ejector rod 260 presses against the proximity sensor 280 , the proximity sensor 280 can generate a specific electrical signal, and the second driving motor 216 can switch to a stop state after receiving the electrical signal from the proximity sensor 280 .
在门体120转动过程中,角度测量装置用于检测门体120相对于关闭位置的枢转角度(以下可简称“门体120的枢转角度”)。其中,门体120相对于关闭位置的枢转角度是指门体120当前位置所在板面与关闭位置所在板面之间的夹角。且在上述步骤S306中,在控制顶杆260开始伸出的同时,启动角度测量装置,以执行检测门体120相对于关闭位置的枢转角度步骤。During the rotation of the door body 120, the angle measuring device is used to detect the pivot angle of the door body 120 relative to the closed position (hereinafter may be referred to as "the pivot angle of the door body 120"). The pivoting angle of the door body 120 relative to the closed position refers to the angle between the board surface where the door body 120 is currently located and the board surface where the closed position is located. And in the above-mentioned step S306, when the ejector rod 260 is controlled to start extending, the angle measuring device is activated to perform the step of detecting the pivot angle of the door body 120 relative to the closed position.
角度测量装置可以为角度传感器,且可以设置于导杆的第一导向部241的第一端。在一些可选的实施例中,角度测量装置还可以设置于门体120的枢转轴上。门体120在关闭位置与打开位置之间往复转动的过程中,角度测量装置可以每隔预设的时间间隔(例 如0.1~1s范围内的任意值)检测一次门体120的枢转角度。The angle measuring device may be an angle sensor, and may be disposed at the first end of the first guide portion 241 of the guide rod. In some optional embodiments, the angle measuring device may also be disposed on the pivot shaft of the door body 120 . During the reciprocating rotation of the door body 120 between the closed position and the open position, the angle measuring device can detect the pivoting angle of the door body 120 once every preset time interval (for example, any value in the range of 0.1-1 s).
上述步骤S308中,第一角度阈值可以为1~5°范围内的任意值,例如2°或者3°。通过判断门体120相对于关闭位置的枢转角度是否大于预设的第一角度阈值,可以确定顶杆260是否已将门体120顶开。在确定顶杆260已顶开门体120的情况下执行步骤S310,这可使导杆顺利地驱动门体120继续向打开位置转动,减少或避免门封条的吸力对门体120的继续转动产生不利影响。In the above step S308, the first angle threshold may be any value within the range of 1° to 5°, for example, 2° or 3°. By judging whether the pivot angle of the door body 120 relative to the closed position is greater than a preset first angle threshold, it can be determined whether the ejector rod 260 has ejected the door body 120 . Step S310 is executed when it is determined that the ejector rod 260 has pushed up the door body 120, which enables the guide rod to smoothly drive the door body 120 to continue to rotate to the open position, reducing or preventing the suction of the door seal from adversely affecting the continued rotation of the door body 120 .
导杆可以位于顶杆260的左侧,且靠近门体120的枢转轴设置,以便于向门体120的枢转轴施加作用力。导杆大致可以为连杆结构。导杆可以包括相互连接且可相对转动的第一导向部241和第二导向部242,还可以进一步地包括用于连接第一导向部241和第二导向部242的转轴部243。第一导向部241和第二导向部242可以分别呈杆状。每个导向部沿其长度方向均具有第一端和第二端。The guide rod may be located on the left side of the top rod 260 and disposed close to the pivot shaft of the door body 120 so as to apply a force to the pivot shaft of the door body 120 . The guide rod can be roughly a connecting rod structure. The guide rod may include a first guide portion 241 and a second guide portion 242 that are connected to each other and are relatively rotatable, and may further include a rotating shaft portion 243 for connecting the first guide portion 241 and the second guide portion 242 . The first guide portion 241 and the second guide portion 242 may be rod-shaped, respectively. Each guide has a first end and a second end along its length.
第一导向部241具有固定连接至第一传动组件的第一端、以及从安装空间向外伸出的第二端。第二导向部242具有可相对转动地连接至第一导向部241的第二端的第一端、以及用于固定连接至冰箱10的门体120的第二端。也就是说,第一导向部241的第一端位于安装空间内且用于与第一传动组件传动连接,第一导向部241的第二端延伸至安装空间外部且用于与第二导向部242的第一端可相对转动地连接。第二导向部242的第二端与冰箱10的门体120固定连接,例如可以通过一铰链固定连接至门体120的枢转轴。The first guide portion 241 has a first end fixedly connected to the first transmission assembly, and a second end extending outward from the installation space. The second guide portion 242 has a first end rotatably connected to the second end of the first guide portion 241 , and a second end for fixedly connecting to the door body 120 of the refrigerator 10 . That is to say, the first end of the first guide portion 241 is located in the installation space and is used for drivingly connecting with the first transmission assembly, and the second end of the first guide portion 241 extends to the outside of the installation space and is used for connecting with the second guide portion The first end of 242 is relatively rotatably connected. The second end of the second guide portion 242 is fixedly connected to the door body 120 of the refrigerator 10, for example, it can be fixedly connected to the pivot shaft of the door body 120 through a hinge.
第一导向部241和第二导向部242可以位于同一水平面内,且可以在该水平面内相对转动。第一导向部241与第二导向部242发生相对转动时,二者之间的夹角大小发生变化。第一导向部241的第二端开设有贯穿其厚度方向的第一装配孔,第二导向部242的第一端开设有贯穿其厚度方向的第二装配孔。此处的“厚度方向”可以指竖直方向。The first guide portion 241 and the second guide portion 242 can be located in the same horizontal plane, and can relatively rotate within the horizontal plane. When the first guide portion 241 and the second guide portion 242 rotate relative to each other, the size of the included angle between them changes. The second end of the first guide portion 241 is provided with a first assembly hole penetrating the thickness direction thereof, and the first end of the second guide portion 242 is provided with a second assembly hole penetrating the thickness direction thereof. The "thickness direction" here may refer to the vertical direction.
图6是图4所示的开闭机构200的导杆的部分结构图。FIG. 6 is a partial configuration diagram of a guide rod of the opening and closing mechanism 200 shown in FIG. 4 .
转轴部243具有旋转导向轴、上限位凸缘243a和下限位凸缘243b。旋转导向轴的中心轴线、上限位凸缘243a的中心轴线和下限位凸缘243b的中心轴线同轴,且沿竖直方向延伸。上限位凸缘243a和下限位凸缘243b大致可以呈圆柱状。其中旋转导向轴装配于第一装配孔和第二装配孔。第一装配孔与旋转导向轴可以固定连接,或者也可以活动连接。上限位凸缘243a和下限位凸缘243b,与旋转导向轴固定连接或与旋转导向轴为一体件,且分别从旋转导向轴的上部区段和下部区段沿径向向外延伸形成,从而使得第一导向部241和第二导向部242可相对转动地套设于旋转导向轴上。也就是说,第一导向部241和第二导向部242套设于旋转导向轴,上限位凸缘243a和下限位凸缘243b的横截面直径大于旋转导向轴的横截面直径,从而可以防止第一导向部241和第二导向部242与旋转导向轴脱离,这可以提高导杆各个部件之间连接的可靠性。The rotating shaft portion 243 has a rotation guide shaft, an upper limit flange 243a and a lower limit flange 243b. The center axis of the rotation guide shaft, the center axis of the upper limit flange 243a, and the center axis of the lower limit flange 243b are coaxial, and extend in the vertical direction. The upper limit flange 243a and the lower limit flange 243b may be substantially cylindrical. The rotation guide shaft is assembled in the first assembly hole and the second assembly hole. The first assembly hole and the rotating guide shaft can be fixedly connected, or can also be movably connected. The upper limit flange 243a and the lower limit flange 243b are fixedly connected with the rotary guide shaft or integrally formed with the rotary guide shaft, and are respectively formed to extend radially outward from the upper and lower sections of the rotary guide shaft, thereby The first guide portion 241 and the second guide portion 242 are sleeved on the rotation guide shaft so as to be relatively rotatable. That is to say, the first guide portion 241 and the second guide portion 242 are sleeved on the rotation guide shaft, and the cross-sectional diameter of the upper limit flange 243a and the lower limit flange 243b is larger than that of the rotation guide shaft, thereby preventing the first The first guide portion 241 and the second guide portion 242 are separated from the rotating guide shaft, which can improve the reliability of the connection between the various components of the guide rod.
第一传动组件和第二传动组件的结构可以相同,且均可以包括门体第一传动齿轮211、门体第二传动齿轮212和门体第三传动齿轮213。The structures of the first transmission assembly and the second transmission assembly may be the same, and each may include a door body first transmission gear 211 , a door body second transmission gear 212 and a door body third transmission gear 213 .
门体第一传动齿轮211连接至对应驱动电机的输出轴。门体第一传动齿轮211可以与第一驱动电机215或者第二驱动段集的输出轴啮合连接,每一驱动电机的输出轴可以形成有与门体第一传动齿轮211的齿啮合的齿形条。在一些可选的实施例中,每一驱动电机的输出轴可以连接至门体第一传动齿轮211的轴。The first transmission gear 211 of the door body is connected to the output shaft of the corresponding driving motor. The first transmission gear 211 of the door body may be engaged with the output shaft of the first drive motor 215 or the second drive segment set, and the output shaft of each drive motor may be formed with a tooth profile that meshes with the teeth of the first transmission gear 211 of the door body strip. In some optional embodiments, the output shaft of each driving motor may be connected to the shaft of the first transmission gear 211 of the door body.
门体第二传动齿轮212与门体第一传动齿轮211啮合。门体第三传动齿轮213与门体第二传动齿轮212同轴,并与顶杆260或者导杆传动连接。门体第三传动齿轮213的位置可以低于门体第二传动齿轮212的位置。且门体第三传动齿轮213的齿根圆直径大 于门体第二传动齿轮212的齿根圆直径。也就是说,门体第三传动齿轮213的整体外形尺寸大于门体第二传动齿轮212的整体外形尺寸,这可以对驱动电机的转动行程起到放大作用,利用小幅度的转动即可驱动顶杆260产生较大的伸缩量,或者驱动导杆产生较大的转动量。The door body second transmission gear 212 meshes with the door body first transmission gear 211 . The third transmission gear 213 of the door body is coaxial with the second transmission gear 212 of the door body, and is in driving connection with the top rod 260 or the guide rod. The position of the third transmission gear 213 of the door body may be lower than the position of the second transmission gear 212 of the door body. And the diameter of the root circle of the third transmission gear 213 of the door body is larger than the diameter of the root circle of the second transmission gear 212 of the door body. That is to say, the overall outer dimension of the third transmission gear 213 of the door body is larger than that of the second transmission gear 212 of the door body, which can amplify the rotation stroke of the driving motor, and the top can be driven by a small rotation. The rod 260 produces a larger amount of telescoping, or the drive guide rod produces a larger amount of rotation.
本实施例的第一传动组件和第二传动组件还可以分别进一步地包括门体第四传动齿轮214,用于将门体第三传动齿轮213传动连接至顶杆260或者导杆。也就是说,门体第三传动齿轮213可以通过一门体第四传动齿轮214与顶杆260或者导杆传动连接。例如门体第四传动齿轮214一方面可以与门体第三传动齿轮213啮合连接,另一方面可以与顶杆260的齿条261啮合连接。又如门体第四传动齿轮214一方面可以与门体第三传动齿轮213啮合连接,另一方面门体第四传动齿轮214的轴可以与导杆的第一导向部241的第一端固定连接。The first transmission assembly and the second transmission assembly of the present embodiment may further include a fourth transmission gear 214 of the door body for drivingly connecting the third transmission gear 213 of the door body to the ejector rod 260 or the guide rod. That is to say, the third transmission gear 213 of the door body may be connected to the ejector rod 260 or the guide rod in a driving manner through a fourth transmission gear 214 of the door body. For example, the fourth transmission gear 214 of the door body may be engaged with the third transmission gear 213 of the door body on the one hand, and may be engaged with the rack 261 of the ejector rod 260 on the other hand. For another example, the fourth transmission gear 214 of the door body can be meshed with the third transmission gear 213 of the door body on the one hand, and the shaft of the fourth transmission gear 214 of the door body can be fixed to the first end of the first guide portion 241 of the guide rod on the other hand. connect.
通过对传动组件的多个传动齿轮进行有机连接,使得本实施例的自动开关门装置能够利用较小的驱动力和较小的电机转动行程实现门体120的开闭,这有利于降低自动开关门装置开闭门体120的难度。By organically connecting a plurality of transmission gears of the transmission assembly, the automatic door opening and closing device of this embodiment can realize the opening and closing of the door body 120 by using a small driving force and a small rotation stroke of the motor, which is beneficial to reduce the automatic opening and closing of the door. The difficulty of opening and closing the door body 120 by the door device.
在控制导杆活动以带动门体120向打开位置转动的步骤中,启动第一驱动电机215,以向导杆提供驱动力,从而使得导杆带动门体120转动。本实施例的导杆的活动方式可以为两种,即,导杆既能带动门体120从关闭位置向打开位置转动,也能带动门体120从打开位置向关闭位置反向转动。第一驱动电机215可以调节导杆的活动方式。导杆的活动方式可以根据开关门信号的类型确定。第一驱动电机215可以具有两种转动方向,即正向转动方向和反向转动方向。在控制导杆活动以带动门体120向打开位置转动的过程中,第一驱动电机215的转动方向为正向转动方向。In the step of controlling the movement of the guide rod to drive the door body 120 to rotate to the open position, the first driving motor 215 is activated to provide driving force to the guide rod, so that the guide rod drives the door body 120 to rotate. The guide rod in this embodiment can move in two ways, that is, the guide rod can drive the door body 120 to rotate from the closed position to the open position, and can also drive the door body 120 to rotate reversely from the open position to the closed position. The first driving motor 215 can adjust the movement mode of the guide rod. The movement mode of the guide rod can be determined according to the type of door switch signal. The first driving motor 215 may have two rotation directions, ie, a forward rotation direction and a reverse rotation direction. In the process of controlling the movement of the guide rod to drive the door body 120 to rotate to the open position, the rotation direction of the first driving motor 215 is the forward rotation direction.
在控制导杆活动以带动门体120向打开位置转动的过程中,控制方法还包括:在门体120相对于关闭位置的枢转角度小于预设的第二角度阈值的情况下,检测门体120的转动速度,第二角度阈值大于第一角度阈值,根据门体120的转动速度对导杆进行控制,使得翻转弹性组件在门体120转动过程中产生压缩形变。第二角度阈值可以根据翻转弹性组件开始产生压缩形变时所需的门体120转动角度大小进行设置,可以为5~15°范围内的任意值,例如可以为8°。门体120的转动速度是指门体120在单位时间内转动的角度,可以根据角度测量装置的检测结果进行计算。In the process of controlling the movement of the guide rod to drive the door body 120 to rotate to the open position, the control method further includes: when the pivot angle of the door body 120 relative to the closed position is smaller than a preset second angle threshold, detecting the door body The rotation speed of the door 120, the second angle threshold is greater than the first angle threshold, and the guide rod is controlled according to the rotation speed of the door body 120, so that the overturning elastic assembly produces compression deformation during the rotation of the door body 120. The second angle threshold can be set according to the rotation angle of the door body 120 required when the flip elastic component starts to produce compression deformation, and can be any value within the range of 5° to 15°, for example, it can be 8°. The rotation speed of the door body 120 refers to the rotation angle of the door body 120 per unit time, which can be calculated according to the detection result of the angle measuring device.
由于导杆在带动门体120向打开位置转动的过程中,翻转弹性组件通过绕轴转动产生压缩形变,这使得导杆在向门体120施加驱动力时不仅需要带动门体120转动,还需使翻转弹性组件产生压缩形变。也就是说,翻转弹性组件在门体120打开过程中可以通过产生压缩形变而“积蓄能量”,在门体120关闭过程中可以通过恢复压缩形变而“释放能量”,从而为门体120关闭提供又一驱动力,使得门体120可以在开闭机构200和翻转机构500的双重作用下朝向关闭位置转动,这可以间接地为翻转梁140提供翻转动力。Since the guide rod is in the process of driving the door body 120 to rotate to the open position, the overturning elastic component is compressed and deformed by rotating around the axis, which makes the guide rod not only need to drive the door body 120 to rotate when applying a driving force to the door body 120, but also need to rotate the door body 120. Compression deformation of the flip elastic component. That is to say, the inversion elastic assembly can “accumulate energy” by generating compressive deformation during the opening process of the door body 120 , and can “release energy” by recovering the compressive deformation during the closing process of the door body 120 , so as to provide the door 120 for closing. Another driving force enables the door body 120 to rotate toward the closed position under the dual action of the opening and closing mechanism 200 and the turning mechanism 500 , which can indirectly provide turning power for the turning beam 140 .

The turning elastic assembly includes an elastic assembly assembling box 530 and a turning elastic member 550 disposed in the elastic assembly assembling box 530 .
图10是图8所示的翻转机构500中翻转弹性组件的示意图,图中虚线示出相邻装配区段之间的分界线。FIG. 10 is a schematic diagram of the inversion elastic component in the inversion mechanism 500 shown in FIG. 8 , and the dotted line in the figure shows the dividing line between adjacent assembly sections.
弹性组件装配盒530具有多个装配区段,多个装配区段包括沿水平方向依次排列的第一装配区段531、第二装配区段532以及第三装配区段533。在门体120处于关闭位置的情况下,第一装配区段531、第二装配区段532以及第三装配区段533可以由左至右依次排布。每一装配区段均具有相对设置的顶壁和底壁。The elastic component assembling box 530 has a plurality of assembling sections, and the plurality of assembling sections includes a first assembling section 531 , a second assembling section 532 and a third assembling section 533 which are arranged in sequence along the horizontal direction. When the door body 120 is in the closed position, the first assembly section 531 , the second assembly section 532 and the third assembly section 533 may be sequentially arranged from left to right. Each assembly section has opposing top and bottom walls.
其中第一装配区段531可转动地套设于轴上区段521和轴下区段523,以使翻转弹性组件绕翻转固定轴520往复转动。第一装配区段531的顶壁上可以形成有贯穿其厚度方向的第三装配孔536,第一装配区段531的底壁上可以形成有贯穿其厚度方向且位于第一装配孔下方的第四装配孔537。第三装配孔536可转动地套设于轴上区段521。第四装配孔537可转动地套设于轴下区段523。The first assembly section 531 is rotatably sleeved on the shaft upper section 521 and the shaft lower section 523 , so that the inversion elastic assembly reciprocates around the inversion fixed shaft 520 . The top wall of the first assembly section 531 may be formed with a third assembly hole 536 penetrating the thickness direction thereof, and the bottom wall of the first assembly section 531 may be formed with a third assembly hole 536 passing through the thickness direction and below the first assembly hole. Four mounting holes 537. The third assembly hole 536 is rotatably sleeved on the shaft upper section 521 . The fourth assembly hole 537 is rotatably sleeved on the shaft lower section 523 .
第二装配区段532内设置有沿多个装配区段的排列方向可往复移动的导引轴535。第三装配区段533形成伸缩空间。第二装配区段532的顶壁上可以形成有贯穿其厚度方向的第一线性孔。第二装配区段532的底壁上可以形成有贯穿其厚度方向且位于第一伸缩孔下方的第二线性孔。导引轴535可以穿设于第一线性孔和第二线性孔内,且在第一线性孔和第二线性孔内沿翻转弹性件550的伸缩方向往复移动。The second assembly section 532 is provided with a guide shaft 535 reciprocatingly movable along the arrangement direction of the plurality of assembly sections. The third assembly section 533 forms a telescopic space. A first linear hole may be formed on the top wall of the second fitting section 532 through the thickness direction thereof. A second linear hole may be formed on the bottom wall of the second assembly section 532 in the thickness direction of the second assembly section 532 and located below the first telescopic hole. The guide shaft 535 can pass through the first linear hole and the second linear hole, and reciprocate in the first linear hole and the second linear hole along the telescopic direction of the inversion elastic member 550 .
翻转弹性件550可以为具备伸缩性能的任意弹性体,例如弹簧,但不限于此。翻转弹性件550沿多个装配区段的排列方向可伸缩地设置于伸缩空间,且与导引轴535固定连接。多个装配区段的排列方向即为翻转弹性件550的伸缩方向。导引轴535上形成有与轮窝部522a的外形相适配的凸出部535a,该凸出部535a从导引轴535的中部区段沿径向向外延伸形成,位于第一线性孔下方以及第二线性孔上方。凸出部535a配置成在冰箱10的门体120打开过程中离开轮窝部522a,转动至轮面部522b,从而使得翻转弹性件550产生压缩形变,还配置成在冰箱10的门体120关闭过程中进入轮窝部522a,从而使得翻转弹性件550恢复压缩形变而释放弹力。也就是说,门体120在转动过程中会带动翻转弹性组件绕翻转固定轴520转动,而在翻转弹性组件转动过程中,凸出部535a会沿转轮的周面移动,从而可以进出轮窝部522a。The inversion elastic member 550 may be any elastic body with stretchability, such as a spring, but is not limited thereto. The inversion elastic member 550 is telescopically disposed in the telescopic space along the arrangement direction of the plurality of assembling sections, and is fixedly connected with the guide shaft 535 . The arrangement direction of the plurality of assembly sections is the extension and contraction direction of the flip elastic member 550 . The guide shaft 535 is formed with a protruding portion 535a which is adapted to the outer shape of the wheel socket portion 522a. The protruding portion 535a extends radially outward from the middle section of the guide shaft 535 and is located in the first linear hole. below and above the second linear hole. The protruding portion 535a is configured to leave the wheel socket portion 522a during the opening process of the door body 120 of the refrigerator 10 and rotate to the wheel surface portion 522b, so as to cause the inversion elastic member 550 to produce compression deformation, and is also configured to close the door body 120 of the refrigerator 10. into the wheel well portion 522a, so that the overturning elastic member 550 recovers the compressive deformation and releases the elastic force. That is to say, during the rotation of the door body 120, the inverting elastic assembly will be driven to rotate around the inverting fixed shaft 520, and during the rotating process of the inverting elastic assembly, the protruding portion 535a will move along the peripheral surface of the runner, so as to enter and exit the wheel well part 522a.
将翻转弹性组件配置成在门体120转动过程中绕翻转固定轴520转动,并将翻转弹性件550连接至可往复移动的导引轴535,且使导引轴535的凸出部535a与转轮的轮窝部522a进行配合,从而可以在不直接向翻转弹性件550提供驱动力的情况下巧妙地实现 翻转弹性件550的压缩和拉伸,使得翻转弹性件550可以通过压缩和拉伸提供梁体翻转的动力。The inversion elastic assembly is configured to rotate around the inversion fixed shaft 520 during the rotation of the door body 120, and the inversion elastic member 550 is connected to the reciprocating guide shaft 535, and the protruding portion 535a of the guiding shaft 535 is connected to the rotary shaft 535. The wheel socket portion 522a of the wheel is matched, so that the compression and stretching of the inversion elastic member 550 can be realized ingeniously without directly providing a driving force to the inversion elastic member 550, so that the inversion elastic member 550 can be provided by compression and tension. The driving force for the overturning of the beam body.
门体120的转动速度可以反映第一驱动电机215的输出转速。在门体120向打开位置转动的过程中,由于第一驱动电机215既需要间接地驱动门体120转动,又需要间接地驱动翻转弹性组件绕轴转动,使得翻转弹性组件的导引轴535的凸出部535a离开轮窝部522a进入轮面部522b从而产生压缩形变。通过对门体120的转动速度大小进行检测,并将门体120的转动速度与预设的转速阈值进行比较,可以确定在第一驱动电机215的输出转速为当前转速的情况下是否能顺利地驱动翻转弹性组件从轮窝部522a进入轮面部522b。The rotational speed of the door body 120 may reflect the output rotational speed of the first driving motor 215 . During the rotation of the door body 120 to the open position, since the first driving motor 215 not only needs to drive the door body 120 to rotate indirectly, but also needs to indirectly drive the inversion elastic assembly to rotate around the axis, so that the guide shaft 535 of the inversion elastic assembly needs to rotate. The protruding portion 535a leaves the wheel well portion 522a and enters the wheel surface portion 522b to cause compression deformation. By detecting the rotational speed of the door body 120 and comparing the rotational speed of the door body 120 with a preset rotational speed threshold, it can be determined whether the rotation can be smoothly driven when the output rotational speed of the first drive motor 215 is the current rotational speed The elastic member enters the wheel surface portion 522b from the wheel well portion 522a.
根据门体120的转动速度对导杆进行控制的步骤可以包括:判断门体120的转动速度是否小于预设的转速阈值,若是,则提高第一驱动电机215的输出转速,若否,则不调整第一驱动电机215的输出转速。例如,第一驱动电机215可以预设有第一预设转速、第二预设转速、第三预设转速等输出转速依次增大的多个转速等级,在启动第一驱动电机215时,可以按照第一预设转速控制第一驱动电机215启动运行。在需要提高第一驱动电机215的输出转速的情况下,可将第一驱动电机215的输出转速调整为第二预设转速或者第三预设转速。The step of controlling the guide rod according to the rotational speed of the door body 120 may include: judging whether the rotational speed of the door body 120 is less than a preset rotational speed threshold, if so, increasing the output rotational speed of the first drive motor 215, if not, not Adjust the output rotational speed of the first drive motor 215 . For example, the first driving motor 215 may be preset with a plurality of rotation speed levels in which the output rotation speed increases sequentially, such as a first preset rotation speed, a second preset rotation speed, and a third preset rotation speed. The first driving motor 215 is controlled to start running according to the first preset rotational speed. When the output speed of the first drive motor 215 needs to be increased, the output speed of the first drive motor 215 can be adjusted to the second preset speed or the third preset speed.
在门体120的转动速度小于预设的转速阈值的情况下,第一驱动电机215可能无法驱动翻转弹性组件产生压缩形变,通过提高第一驱动电机215的输出转速,可以提高门体120的转动速度,从而保证翻转弹性组件在门体120转动过程中顺利地产生压缩形变。转速阈值可以根据翻转弹性组件产生压缩形变时所需的门体120转速的最小值进行设置,例如可以为0.5~5°/s范围内的任意值。When the rotational speed of the door body 120 is less than the preset rotational speed threshold, the first driving motor 215 may not be able to drive the flip elastic component to produce compression deformation. By increasing the output rotational speed of the first driving motor 215, the rotation of the door body 120 can be increased. speed, so as to ensure that the inversion elastic assembly smoothly produces compression deformation during the rotation process of the door body 120 . The rotational speed threshold may be set according to the minimum rotational speed of the door body 120 required when the elastic assembly is flipped to produce compression deformation, and may be any value within the range of 0.5°/s to 5°/s, for example.
在控制导杆活动以带动门体120向打开位置转动的过程中,控制方法还可以包括:在门体120相对于关闭位置的枢转角度大于等于第二角度阈值的情况下,检测门体120的转动速度变化率,根据门体120的转动速度变化率调整第一驱动电机215的输出转速。转动速度变化率是指门体120的转动速度的变化快慢,可以根据角度测量装置的检测结果进行计算。在门体120的枢转角度大于等于第二角度阈值的情况下,翻转弹性组件已产生压缩形变,门体120在导杆的带动下继续向打开位置转动,通过检测门体120的转动速度变化率,可以判断门体120在继续转动的过程中是否因遇到障碍物(例如冰箱10的使用者,或者桌椅等物品)而产生“急停”或者“骤停”现象,还可以判断门体120是否已到达打开位置。In the process of controlling the movement of the guide rod to drive the door body 120 to rotate to the open position, the control method may further include: when the pivot angle of the door body 120 relative to the closed position is greater than or equal to a second angle threshold, detecting the door body 120 According to the rotation speed change rate of the door body 120, the output speed of the first drive motor 215 is adjusted. The rate of change of the rotation speed refers to the speed of change of the rotation speed of the door body 120 , and can be calculated according to the detection result of the angle measuring device. When the pivot angle of the door body 120 is greater than or equal to the second angle threshold, the overturning elastic component has produced compression deformation, and the door body 120 continues to rotate to the open position under the driving of the guide rod. By detecting the change of the rotation speed of the door body 120 rate, it can be judged whether the door 120 encounters an obstacle (such as the user of the refrigerator 10, or items such as tables and chairs) and the phenomenon of “emergency stop” or “sudden stop” occurs during the continuous rotation of the door body 120. It can also be judged that the door Whether the body 120 has reached the open position.
其中,根据门体120的转动速度变化率调整第一驱动电机215的输出转速的步骤可以包括:判断门体120的转动速度变化率是否大于预设的变化率阈值,若是,则将第一驱动电机215的输出转速调整为预设的最低输出转速。Wherein, the step of adjusting the output speed of the first driving motor 215 according to the rate of change of the rotational speed of the door body 120 may include: judging whether the rate of change of the rotational speed of the door body 120 is greater than a preset rate of change threshold, and if so, the first driving The output speed of the motor 215 is adjusted to a preset minimum output speed.
变化率阈值可以为多个,且可以根据第一驱动电机215的输出转速进行选择。第一驱动电机215的每一输出转速对应有一变化率阈值。通过对第一驱动电机215的输出转速进行检测,可以选择对应的变化率阈值。变化率阈值可以为1~10°范围内的任意值。There may be multiple thresholds for the rate of change, and may be selected according to the output rotational speed of the first driving motor 215 . Each output speed of the first driving motor 215 corresponds to a rate of change threshold. By detecting the output rotational speed of the first driving motor 215, a corresponding change rate threshold can be selected. The rate of change threshold can be any value within the range of 1 to 10°.
本实施例中,第一驱动电机215还可以配置有预设的最低输出转速,预设的最低输出转速可以为0。当第一驱动电机215的输出转速为0时,第一驱动电机215为待机状态。在门体120的转动速度变化率大于预设的变化率阈值的情况下,若门体120的枢转角度小于与打开位置相对应的枢转角度,则门体120可能产生“急停”或者“骤停”现象,此时通过将第一驱动电机215的输出转速调整为最低输出转速,可防止第一驱动电机215 烧坏,避免导杆产生机械损伤,提高开闭机构200运行的可靠性。In this embodiment, the first drive motor 215 may also be configured with a preset minimum output speed, and the preset minimum output speed may be zero. When the output rotational speed of the first drive motor 215 is 0, the first drive motor 215 is in a standby state. Under the condition that the rate of change of the rotation speed of the door body 120 is greater than the preset rate of change threshold, if the pivot angle of the door body 120 is smaller than the pivot angle corresponding to the opening position, the door body 120 may generate an “emergency stop” or "Sudden stop" phenomenon, at this time, by adjusting the output speed of the first drive motor 215 to the minimum output speed, the first drive motor 215 can be prevented from burning out, the guide rod can be prevented from mechanical damage, and the operation reliability of the opening and closing mechanism 200 can be improved. .
在门体120的枢转角度达到与打开位置相对应的门体120枢转角度时,可以控制第一驱动电机215切换为待机状态。在门体120的转动速度变化率大于预设的变化率阈值的情况下,若门体120的枢转角度等于与打开位置相对应的枢转角度,则门体120可能未发生“急停”或者“骤停”现象,而是已到达开门信号所指示的打开位置,此时通过将第一驱动电机215调整为待机状态,可防止门体120因过度打开而散失较多冷量。在门体120已到达打开位置的情况下,若检测到门体120继续朝向远离关闭位置的方向转动(例如用户可能会向门体120施加作用力使得门体120继续转动),且继续转动的角度超出1~5°,则可以重新启动第一驱动电机215,使得第一驱动电机215驱动导杆活动以带动门体120向下一打开位置转动。When the pivoting angle of the door body 120 reaches the pivoting angle of the door body 120 corresponding to the open position, the first driving motor 215 may be controlled to switch to the standby state. Under the condition that the rate of change of the rotation speed of the door body 120 is greater than the preset rate of change threshold, if the pivot angle of the door body 120 is equal to the pivot angle corresponding to the opening position, the door body 120 may not have an “emergency stop” Or "sudden stop" phenomenon, but has reached the opening position indicated by the door opening signal, at this time, by adjusting the first drive motor 215 to the standby state, the door body 120 can be prevented from being excessively opened and lose more cooling capacity. When the door body 120 has reached the open position, if it is detected that the door body 120 continues to rotate in a direction away from the closed position (for example, the user may apply force to the door body 120 to make the door body 120 continue to rotate), and the door body 120 continues to rotate. If the angle exceeds 1-5°, the first driving motor 215 can be restarted, so that the first driving motor 215 drives the guide rod to move so as to drive the door body 120 to rotate to the next open position.
在门体120向打开位置转动的过程中,翻转梁140翻转至翻折位置。在门体120转动至打开位置之后,控制方法还可以包括:获取冰箱10的关门信号,控制导杆活动以带动门体120向关闭位置转动,且在门体120向关闭位置转动的过程中驱使翻转梁140翻转至舒展位置,即,促使翻转弹性组件通过绕轴反向转动恢复压缩形变而释放弹力。在控制导杆活动以带动门体120向关闭位置转动的过程中,第一驱动电机215的转动方向为反向转动方向。During the rotation of the door body 120 to the open position, the turning beam 140 is turned over to the folded position. After the door body 120 is rotated to the open position, the control method may further include: acquiring a door closing signal of the refrigerator 10, controlling the movement of the guide rod to drive the door body 120 to rotate to the closed position, and driving the door body 120 to rotate to the closed position during the process of rotating the door body 120 to the closed position. The inversion beam 140 is inverted to the stretched position, ie, the inversion elastic component is urged to recover the compression deformation by reverse rotation about the axis to release the elastic force. In the process of controlling the movement of the guide rod to drive the door body 120 to rotate to the closed position, the rotation direction of the first driving motor 215 is the reverse rotation direction.
其中获取冰箱10的关门信号的步骤可以包括:检测门体120处于打开位置的开门时长,判断开门时长是否超出预设的时长阈值,若是,则生成关门信号。时长阈值可以根据用户的使用习惯进行预先设置,例如可以为1~5min范围内的任意值,但不限于此。使用上述方法,可以在用户忘记关门的情况下自动地关门门体,有利于提高冰箱10的自动化程度。The step of acquiring the door closing signal of the refrigerator 10 may include: detecting the door opening duration when the door body 120 is in the open position, judging whether the door opening duration exceeds a preset duration threshold, and if so, generating a door closing signal. The duration threshold may be preset according to the user's usage habits, for example, may be any value within the range of 1 to 5 minutes, but is not limited thereto. Using the above method, the door body can be automatically closed when the user forgets to close the door, which is beneficial to improve the automation degree of the refrigerator 10 .
在一些可选的实施例中,还可以针对获取冰箱10的关门信号的方法进行变换。例如冰箱10可以接收用户发送的关门指令,该关门指令可以由用户通过语音发送到冰箱10的语音交互模块,冰箱10接收到关门指令后可以生成关门信号。In some optional embodiments, the method for acquiring the door closing signal of the refrigerator 10 may also be changed. For example, the refrigerator 10 may receive a door closing instruction sent by the user, and the door closing instruction may be sent by the user to the voice interaction module of the refrigerator 10 through voice, and the refrigerator 10 may generate a door closing signal after receiving the door closing instruction.
在另一些可选的实施例中,还可以针对获取冰箱10的关门信号的方法进行另一变换。例如在确定门体120处于打开位置之后,若角度测量装置检测到当前门体120的枢转角度相对于与打开位置相对应的枢转角度有所减小(例如减小1~5°),也可以触发关门信号。In some other optional embodiments, another transformation may be performed on the method for acquiring the door closing signal of the refrigerator 10 . For example, after it is determined that the door body 120 is in the open position, if the angle measuring device detects that the current pivot angle of the door body 120 has decreased relative to the pivot angle corresponding to the open position (for example, decreased by 1-5°), The door closing signal can also be triggered.
在控制导杆活动以带动门体120向关闭位置转动的同时,控制方法还可以包括:检测门体120相对于关闭位置的枢转角度,判断枢转角度是否小于预设的第三角度阈值,第三角度阈值大于第二角度阈值,若是,则对导杆进行控制以提高门体120的转动速度,使得翻转弹性组件在门体120转动过程中恢复压缩形变。第三角度阈值与第二角度阈值之间的差值可以为1~10°范围内的任意值。While controlling the movement of the guide rod to drive the door body 120 to rotate to the closed position, the control method may further include: detecting the pivot angle of the door body 120 relative to the closed position, and judging whether the pivot angle is smaller than a preset third angle threshold, The third angle threshold is greater than the second angle threshold, and if so, the guide rod is controlled to increase the rotation speed of the door body 120 , so that the overturning elastic assembly restores the compression deformation during the rotation process of the door body 120 . The difference between the third angle threshold and the second angle threshold may be any value in the range of 1-10°.
在门体120从打开位置向关闭位置转动的过程中,由于第一驱动电机215既需要间接地驱动门体120转动,又需要间接地驱动翻转弹性组件绕轴转动,使得翻转弹性组件的导引轴535的凸出部535a离开轮面部522b进入轮窝部522a从而恢复压缩形变。通过提前提高门体120的转动速度,可以顺利地驱动翻转弹性组件从轮面部522b进入轮窝部522a。During the rotation of the door body 120 from the open position to the closed position, since the first drive motor 215 not only needs to drive the door body 120 to rotate indirectly, but also needs to indirectly drive the inversion elastic assembly to rotate around the axis, so that the guiding of the inversion elastic assembly The protruding portion 535a of the shaft 535 leaves the wheel surface portion 522b and enters the wheel well portion 522a to restore the compression deformation. By increasing the rotational speed of the door body 120 in advance, the turning elastic assembly can be smoothly driven from the wheel surface portion 522b into the wheel well portion 522a.
门体120的转动速度由第一驱动电机215进行调节。在控制导杆活动以带动门体120向关闭位置转动时,可以按照第一预设转速控制第一驱动电机215启动运行。在需要提高第一驱动电机215的输出转速的情况下,可将第一驱动电机215的输出转速调整为第 二预设转速或者第三预设转速。The rotation speed of the door body 120 is adjusted by the first driving motor 215 . When the control guide rod moves to drive the door body 120 to rotate to the closed position, the first driving motor 215 can be controlled to start running according to the first preset rotational speed. When the output speed of the first drive motor 215 needs to be increased, the output speed of the first drive motor 215 can be adjusted to the second preset speed or the third preset speed.
在门体120的枢转角度小于第三角度阈值的情况下,通过及时调整第一驱动电机215的输出转速,可以提高门体120的转动速度,从而保证翻转弹性组件在门体120转动过程中顺利地恢复压缩形变,有利于提高翻转过程的可靠性,减少或避免卡死现象。When the pivot angle of the door body 120 is smaller than the third angle threshold, by adjusting the output speed of the first drive motor 215 in time, the rotation speed of the door body 120 can be increased, thereby ensuring that the flip elastic assembly is rotated during the door body 120 . The smooth recovery of the compression deformation is beneficial to improve the reliability of the turning process and reduce or avoid the stuck phenomenon.
