随着生活水平的提高，冰箱等电器设备广泛深入到人们的生活中。为了保持上述电器设备的密封性能，通常在冰箱的箱体和门体之间设置吸附结构或者保持内外负压，以将门体稳定地固定在箱体上。这样做虽然提升了电器设备的相关性能，但是也一定程度上增加了开启门体的难度。通常需要较大的力量才能拉开冰箱的门体，使用多有不便。因此，为了提升操作的便捷性和安全性，可在门体和箱体之间设置自动开关门装置，通过驱动机构驱动开关门执行机构实现辅助开关门。但是相关技术的开关门装置结构相对复杂，体积规格较大，装配到电器设备上，空间占用需求较大，特别是在高度方向，导致电器设备对现场布置的高度条件要求较高，对于电器产品的现场安置造成一定的不便；同时过于高的自动开关门装置，也影响产品美观度。 With the improvement of living standards, refrigerators and other electrical equipment have become widely integrated into people's lives. In order to maintain the sealing performance of the above-mentioned electrical equipment, an adsorption structure is usually provided between the box and the door of the refrigerator or internal and external negative pressure is maintained to stably fix the door to the box. Although this improves the performance of electrical equipment, it also increases the difficulty of opening the door to a certain extent.

参见图5，在一些实施方式中，可将第一传动组件210设置成第一传动齿轮212，通过齿轮啮合传动的方式传递驱动力。考虑到齿轮绕其轴线转动的工作方式，可以将卡槽211设置在第一传动齿轮212的轴向端面上，便于建立连接端231与第一传动齿轮212的连接状态和解除连接状态，且降低对其转动和齿部啮合的工作状态的影响。Referring to FIG. 5 , in some embodiments, the first transmission component 210 can be configured as a first transmission gear 212 to transmit driving force through gear meshing transmission. Taking into account the working mode of the gear rotating around its axis, the slot 211 can be provided on the axial end surface of the first transmission gear 212 to facilitate the establishment and disconnection of the connecting end 231 and the first transmission gear 212, and reduce the Influence on the working state of its rotation and tooth meshing.

值得说明的是，为了配合的第一传动齿轮212的工作姿态，第二传动组件220的运动方式也可以是类似第一传动齿轮212的绕一轴转动的方式，从而实现同步转动传动。It is worth noting that, in order to match the working posture of the first transmission gear 212, the movement mode of the second transmission component 220 can also be similar to the rotation mode of the first transmission gear 212 around an axis, thereby achieving synchronous rotational transmission.

参见图6，在一些实施方式中，可以将第二传动组件220设置成第二传动齿轮222，并可将第一传动齿轮212与第二传动齿轮222设置成同轴转动的结构形式；连接端231可以设置在第二传动齿轮222上，通过推动顶推端232，以使得连接端231与第一传动齿轮212的连接，使得第一传动齿轮212和第二传动齿轮222连接并同步转动，建立连通的驱动力传递路径。Referring to Figure 6, in some embodiments, the second transmission assembly 220 can be configured as a second transmission gear 222, and the first transmission gear 212 and the second transmission gear 222 can be configured to coaxially rotate; the connection end 231 can be disposed on the second transmission gear 222, and by pushing the pushing end 232 to connect the connecting end 231 with the first transmission gear 212, so that the first transmission gear 212 and the second transmission gear 222 are connected and rotate synchronously to establish Connected driving force transmission paths.

参见图2、图3、图11和图12，在一些实施方式中，为了实现第一传动齿轮212和第二传动齿轮222的转动需求，可在底座900上设置转轴结构，以引导第一传动齿轮212和第二传动齿轮222装配和转动。在另一些实施方式中，可在底座900上设置共用转轴920，以将第一传动齿轮212和第二传动齿轮222的沿轴向套接在共用转轴920上，从而保证了齿轮转动的功能稳定。Referring to Figures 2, 3, 11 and 12, in some embodiments, in order to realize the rotation requirements of the first transmission gear 212 and the second transmission gear 222, a rotating shaft structure can be provided on the base 900 to guide the first transmission gear. Gear 212 and second transmission gear 222 assemble and rotate. In other embodiments, a common rotating shaft 920 can be provided on the base 900 to axially sleeve the first transmission gear 212 and the second transmission gear 222 on the common rotating shaft 920, thereby ensuring the functional stability of the gear rotation. .

在一些实施方式中，可将共用转轴920设置成变截面轴，自底座900向上依次布置的支撑柱921和转轴柱922，支撑柱921的直径可以大于第二传动齿轮222上开设的轴孔的孔径，转轴柱922的直径可以适配第二传动齿轮222的轴孔的孔径，从而第二传动齿轮222可搁置在支撑柱921上，并套接在转轴柱922上，使得第二传动齿轮222离底座900一定高度，并可稳定转动。第一传动齿轮212可叠置在第二传动齿轮222上，并套接在转 轴柱922上实现转动。In some embodiments, the common rotating shaft 920 can be set as a variable cross-section shaft, and the support column 921 and the rotating shaft column 922 are arranged in sequence from the base 900 upward. The diameter of the support column 921 can be larger than the aperture of the shaft hole opened on the second transmission gear 222, and the diameter of the rotating shaft column 922 can be adapted to the aperture of the shaft hole of the second transmission gear 222, so that the second transmission gear 222 can be placed on the support column 921 and sleeved on the rotating shaft column 922, so that the second transmission gear 222 is at a certain height from the base 900 and can rotate stably. The first transmission gear 212 can be stacked on the second transmission gear 222 and sleeved on the rotating shaft column 922. Rotation is achieved on the shaft column 922.

在一些实施方式中，连接端231可以固设于第二传动齿轮222的轴向端面上，通过推动顶推端232，实现将第二传动齿轮222整体推向或推离第一传动齿轮212，使得连接端231与卡槽211嵌合或者自卡槽211脱离。整体操作简单，且结构件的成型相对简洁，装配操作也简洁高效。In some embodiments, the connecting end 231 can be fixed on the axial end surface of the second transmission gear 222, and by pushing the pushing end 232, the second transmission gear 222 can be pushed to or away from the first transmission gear 212 as a whole. The connecting end 231 is fitted into the slot 211 or detached from the slot 211 . The overall operation is simple, the molding of structural parts is relatively simple, and the assembly operation is also simple and efficient.

参见图6，在一些实施方式中，可在第二传动齿轮222上设置卡孔221，且连接端231可移动地嵌设在卡孔221内，从而推动顶推端232，使得连接端231相对于卡孔221移动，靠近第一传动齿轮212，进而卡入上述卡槽211，建立第一传动齿轮212和第二传动齿轮222的连接。在连接端231从卡槽211脱离时，连接端231也相对卡孔221移动；过程中，传动连接件的移动操作对第一传动齿轮212和第二传动齿轮222的位置和姿态的影响会较低，便于保持其转动的位置和姿态，有助于维持装置的工作状态和运行可靠性。Referring to Figure 6, in some embodiments, a clamping hole 221 can be provided on the second transmission gear 222, and the connecting end 231 is movably embedded in the clamping hole 221, thereby pushing the pushing end 232 so that the connecting end 231 faces each other. Move in the clamping hole 221, approach the first transmission gear 212, and then snap into the above-mentioned clamping slot 211 to establish the connection between the first transmission gear 212 and the second transmission gear 222. When the connecting end 231 is detached from the slot 211, the connecting end 231 also moves relative to the slot 221; during the process, the moving operation of the transmission connector will have a greater impact on the positions and postures of the first transmission gear 212 and the second transmission gear 222. Low, easy to maintain its rotating position and attitude, helping to maintain the working condition and operational reliability of the device.

在一些实施方式中，也可将卡槽211设置成轴向贯穿第一传动齿轮212的通孔，从而能够避免连接端231直接推顶卡槽211的槽底，造成不必要的扰动，能够保持第一传动齿轮212转动过程的稳定性。In some embodiments, the clamping slot 211 can also be provided as a through hole that axially penetrates the first transmission gear 212, thereby preventing the connecting end 231 from directly pushing the bottom of the clamping slot 211, causing unnecessary disturbance, and maintaining the The stability of the rotation process of the first transmission gear 212.

在一些实施方式中，考虑到第一传动齿轮212和第二传动齿轮222的转动的工作方式，为了增加连接端231卡入到卡槽211的效率，可将连接端231设置成多个连接臂2311，相应地，卡槽211的数量可与连接臂2311的数量相同，也可以是更多，以降低连接臂2311卡入卡槽211的难度。In some embodiments, considering the rotation working mode of the first transmission gear 212 and the second transmission gear 222, in order to increase the efficiency of the connecting end 231 being inserted into the slot 211, the connecting end 231 can be configured as a plurality of connecting arms 2311. Accordingly, the number of the slots 211 can be the same as the number of the connecting arms 2311, or can be more, so as to reduce the difficulty of the connecting arms 2311 being inserted into the slots 211.

值得说明的是，卡槽211的转动轨迹应当与连接臂2311的移动轨迹相交，从而使得连接臂2311可以嵌入卡槽211内。It is worth mentioning that the rotation trajectory of the card slot 211 should intersect with the movement trajectory of the connecting arm 2311, so that the connecting arm 2311 can be embedded in the card slot 211.

在一些实施方式中，连接臂2311到第二传动齿轮222的转轴轴线的距离与卡槽211到第一传动齿轮212的转轴轴线的距离应当一致，从而在轴线方向上，卡槽211与连接臂2311能够稳定卡合和脱离。从而使得对顶推端231的顶推力沿第二传动齿轮222的转轴轴线方向，其加工和装配时均可以转轴轴线为参考，便于离合顶推组件240的设置，装配和顶推操作。In some embodiments, the distance between the connecting arm 2311 and the axis of rotation of the second transmission gear 222 and the distance between the slot 211 and the axis of the rotation axis of the first transmission gear 212 should be consistent, so that in the axial direction, the distance between the slot 211 and the connecting arm 2311 can engage and disengage stably. Therefore, the pushing force on the pushing end 231 is along the axis of the rotation axis of the second transmission gear 222. The axis of the rotation axis can be used as a reference during processing and assembly, which facilitates the setting, assembly and pushing operation of the clutch pushing assembly 240.

值得说明的是，连接臂2311到第二传动齿轮222的转轴轴线的距离与卡槽211到第一传动齿轮212的转轴轴线的距离也可以不一致，仅需要保证卡槽211的转动轨迹应当与连接臂2311的移动轨迹相交，并且在连接臂2311和卡槽211均有多个的时候，合理设置多个连接臂2311的间隔和多个卡槽211间的间隔，以避免无法稳定嵌入。It is worth noting that the distance between the connecting arm 2311 and the axis of the rotation axis of the second transmission gear 222 and the distance between the slot 211 and the axis of the rotation axis of the first transmission gear 212 may also be inconsistent. It only needs to be ensured that the rotation trajectory of the slot 211 should be consistent with the connection. The movement trajectories of the arms 2311 intersect, and when there are multiple connecting arms 2311 and multiple card slots 211 , the intervals between the multiple connecting arms 2311 and the multiple card slots 211 should be set appropriately to avoid unstable embedding.

在一些实施方式中，可将多个连接臂2311等间隔布置在一个圆形轨迹上，相应地，多个卡槽211也可等间隔布置在上述圆形轨迹上，从而能够形成良好适配的位置和间隔布置模式，便于卡嵌。In some embodiments, multiple connecting arms 2311 may be arranged at equal intervals on a circular trajectory, and correspondingly, multiple card slots 211 may also be arranged at equal intervals on the above circular trajectory, thereby forming a well-fitting position and spacing arrangement pattern for easy insertion.

值得说明的是，为了增加连接臂2311与卡槽211适配嵌合的效率，可适当增加卡槽211的数量，可将卡槽211的数量设置成连接臂2311数量的整数倍，从而在等间隔布置卡槽211和连接臂的情况下，能够大幅增加连接臂2311与卡槽211适配嵌合的效率。It is worth noting that in order to increase the efficiency of the fitting between the connecting arm 2311 and the slot 211, the number of the slots 211 can be appropriately increased, and the number of the slots 211 can be set to an integer multiple of the number of the connecting arms 2311, so that when the slots 211 and the connecting arms are arranged at equal intervals, the efficiency of the fitting between the connecting arm 2311 and the slot 211 can be greatly increased.

在一些实施方式中，多个连接臂2311也可以设置在多个圆形轨迹上，相应地，在第一传动齿轮212应当参考圆形轨迹，设置适配数量的卡槽211，以保证能够稳定嵌合。In some embodiments, multiple connecting arms 2311 can also be arranged on multiple circular trajectories. Correspondingly, an appropriate number of slots 211 should be provided on the first transmission gear 212 with reference to the circular trajectory to ensure stability. chimeric.

在一些实施方式中，传动连接件的顶推端232直接与顶推套241连接，考虑到顶推方向与第二传动齿轮222和第一传动齿轮212的转动方向垂直，可将传动连接件设置成绕第二传动齿轮222的转轴转动的形式；顶推端232转动地设置在顶推套241上，从而可兼顾传动连接件的转动和轴向移动的工作状态。In some embodiments, the pushing end 232 of the transmission connection member is directly connected to the pushing sleeve 241. Considering that the pushing direction is perpendicular to the rotation direction of the second transmission gear 222 and the first transmission gear 212, the transmission connection member can be set as In the form of rotating around the rotation axis of the second transmission gear 222; the push end 232 is rotatably arranged on the push sleeve 241, so that the working state of the rotation and axial movement of the transmission connection can be taken into account.

可将传动连接组件230的顶推端232包括环形座，且环形座可转动地连接在顶推套241上，实现传动连接组件230的转动和轴向移动的工作状态。另一方面，顶推套241仅需要轴向顶推环形座即可，不必考虑其转动状态，极大地简化了离合顶推组件240的结构设置和安装配置。The pushing end 232 of the transmission connection component 230 may include an annular seat, and the annular seat is rotatably connected to the push sleeve 241 to realize the working state of rotation and axial movement of the transmission connection component 230 . On the other hand, the push sleeve 241 only needs to axially push the annular seat without considering its rotational state, which greatly simplifies the structural setting and installation configuration of the clutch push assembly 240 .

值得说明的是，为了降低传动连接组件230移动操作对第一传动齿轮212和第二传动齿轮222的干扰，可将环形座设置在第二传动齿轮222的远离第一传动齿轮212的一 侧，连接臂轴2311向穿过第二传动齿轮222，并可进一步移动卡入卡槽211内，使顶推环形座的操作不会在延伸到两个传动齿轮之间，能够保持二者的相对稳定。It is worth noting that in order to reduce the interference of the moving operation of the transmission connection assembly 230 on the first transmission gear 212 and the second transmission gear 222, the annular seat can be disposed on a side of the second transmission gear 222 away from the first transmission gear 212. side, the connecting arm shaft 2311 passes through the second transmission gear 222, and can be further moved and inserted into the slot 211, so that the operation of pushing the annular seat will not extend between the two transmission gears, and the two transmission gears can be maintained. relatively stable.

参见图8，在一些实施方式中，顶推套241作为顶推媒介，可在顶推套241上设置轴套部2412和推顶部2411，可将环形座套接在轴套部2412上，保持环形座可转动的状态；相应地，推顶部2411用于接受推杆242推顶力，使得顶推套241整体沿第一传动齿轮212的转轴轴线方向移动，从而实施传动连接件的顶推操作。Referring to Figure 8, in some embodiments, the push sleeve 241 serves as a push medium. A sleeve portion 2412 and a push top portion 2411 can be provided on the push sleeve 241, and an annular seat can be sleeved on the sleeve portion 2412 to maintain The annular seat is in a rotatable state; accordingly, the push top 2411 is used to receive the push force of the push rod 242, so that the push sleeve 241 as a whole moves along the axis of the rotation axis of the first transmission gear 212, thereby performing the push operation of the transmission connection. .

在一些实施方式中，顶推套241的移动方向可以为第二传动齿轮222的转轴轴向，为了便于描述将顶推套241移动的方向定为第一方向。为了降低装置的整体厚度，降低成型和装配难度，可采用变向顶推的方式推动顶推套241，也就是说，推杆242的推动方向并不在第一方向，而是存在一定的角度，从而降低在第一方向的空间占用需求。In some embodiments, the moving direction of the push sleeve 241 may be the axial direction of the rotation shaft of the second transmission gear 222. For convenience of description, the moving direction of the push sleeve 241 is defined as the first direction. In order to reduce the overall thickness of the device and reduce the difficulty of molding and assembly, the push sleeve 241 can be pushed in a direction-changing push manner. That is to say, the pushing direction of the push rod 242 is not in the first direction, but at a certain angle. Thereby reducing the space occupation requirement in the first direction.

参见图8、图9和图10，可以在推顶部2411设置第一顶推面2413，在推杆242上设置第二顶推面2421，第一顶推面2413和第二顶推面2421可接触并可相对滑动，并且将第一顶推面2413相对于第一方向设置成锐角，能够通过顶推第一顶推面2413实现沿第一方向的顶推顶推套241，进而推动传动连接件推向第一传动齿轮222。Referring to Figures 8, 9 and 10, a first push surface 2413 can be provided on the push top 2411, and a second push surface 2421 can be provided on the push rod 242. The first push surface 2413 and the second push surface 2421 can be Contact and can slide relatively, and the first pushing surface 2413 is set at an acute angle relative to the first direction, and the pushing sleeve 241 can be pushed along the first direction by pushing the first pushing surface 2413, thereby promoting the transmission connection. The component is pushed toward the first transmission gear 222.

在一些实施方式中，为了优化顶推操作的效率，可将第一顶推面2413与第一方向的夹角设置在30度～60度范围内，例如30度、45度或者60度等。In some embodiments, in order to optimize the efficiency of the pushing operation, the angle between the first pushing surface 2413 and the first direction can be set in the range of 30 degrees to 60 degrees, such as 30 degrees, 45 degrees or 60 degrees.

在一些实施方式中，可将推杆242的顶推方向与第一方向的夹角按照90度控制，尽量缩小推杆242与传动连接件的配合关系所需要的布置空间，降低装置整体体积规模。In some embodiments, the angle between the pushing direction of the push rod 242 and the first direction can be controlled at 90 degrees to minimize the layout space required for the matching relationship between the push rod 242 and the transmission connector, and reduce the overall volume of the device. .

参见图9和图10，在一些实施方式中，为了平衡顶推套241的受力，可将第一顶推面2413的数量设置成两个，相应的推杆242也设置有两个推臂2422，对应顶推两个第一顶推面2413；从而通过两点施力的方式保证顶推套的受力均匀性。并可将两个推臂2422连接在同一个连接部2423上，实现同步动作且保证施力的大小一致，保证顶推套241受力均匀。相应地，两个推臂2422上分别设置有第二顶推面2421。Referring to Figures 9 and 10, in some embodiments, in order to balance the force of the push sleeve 241, the number of the first push surfaces 2413 can be set to two, and the corresponding push rod 242 is also provided with two push arms. 2422, corresponding to the two first pushing surfaces 2413; thereby ensuring the force uniformity of the pushing sleeve through two points of force application. And the two push arms 2422 can be connected to the same connecting part 2423 to achieve synchronous action and ensure the force is consistent, ensuring that the push sleeve 241 is evenly stressed. Correspondingly, the two push arms 2422 are respectively provided with second push surfaces 2421.

在一些实施方式中，可将两个第一顶推面2413设置于顶推套241的相背两侧，两个推臂2422并列设置，第二顶推面2421可以设置在推臂2422上的远离连接部2423的端部，能够通过顶推连接部2423即可实现顶推操作。In some embodiments, two first pushing surfaces 2413 can be disposed on opposite sides of the pushing sleeve 241, two push arms 2422 are disposed side by side, and the second pushing surface 2421 can be disposed on the push arm 2422. The end far away from the connecting part 2423 can be pushed by pushing the connecting part 2423 to achieve the pushing operation.

在一些实施方式中，可以根据顶推套241的规格情况，将第一顶推面2413、第二顶推面2421以及推臂2422的数量设置成两个以上。In some embodiments, the number of the first pushing surface 2413 , the second pushing surface 2421 and the pushing arms 2422 can be set to more than two according to the specifications of the pushing sleeve 241 .

参见图2和图3，为了实施推杆242的顶推操作，可在推杆242上连接直线驱动器243，沿第二方向顶推推杆242或者复位，从而通过直线驱动器推动所述的顶推套241沿第一方向移动。在直线驱动器243复位时，推杆242释放顶推套241。Referring to Figures 2 and 3, in order to implement the pushing operation of the push rod 242, a linear driver 243 can be connected to the push rod 242, and the push rod 242 can be pushed in the second direction or reset, thereby pushing the push rod 242 through the linear driver. The sleeve 241 moves in the first direction. When the linear drive 243 is reset, the push rod 242 releases the push sleeve 241 .

在一些实施方式中，直线驱动器243可采用电磁推杆，滚珠丝杆等直线驱动组件。In some embodiments, the linear drive 243 may use an electromagnetic push rod, a ball screw, or other linear drive components.

参见图12，在一些实施方式中，为了降低推杆242与底座900以及底座900与顶推套241之间的冲击振动，可在底座900与推杆242之间，以及顶推套241与底座900之间设置减震垫244。Referring to FIG. 12 , in some embodiments, in order to reduce the impact vibration between the push rod 242 and the base 900 and the base 900 and the push sleeve 241 , the push rod 242 and the push rod 242 can be placed between the base 900 and the push sleeve 241 and the push sleeve 241 and the base. Shock absorbing pads 244 are provided between 900 and 900.

在一些实施方式中，由于顶推套241受到环形座的轴向摩擦作用，因此存在一定的周向转动的趋势，为此容易影响与离合顶推组件240的配合。可在底座900上设置防转机构930，沿第一方向卡嵌进顶推套241内，用于止挡顶推套241的周向转动。In some embodiments, the push sleeve 241 has a tendency to rotate in the circumferential direction due to the axial friction of the annular seat, which easily affects the cooperation with the clutch push assembly 240. An anti-rotation mechanism 930 can be provided on the base 900, which is embedded in the push sleeve 241 along the first direction to stop the push sleeve 241 from rotating in the circumferential direction.

参见图8、图12和图13，在一些实施方式中，防转机构930可包括防转筋条931，且防转筋条931可在第一方向上与顶推套241相对滑动，从而可兼顾防止顶推套241周向转动和第一方向滑动的效果。一般来说，可在顶推套241内开设防转卡槽2414，与防转筋条931适配，二者沿第一方向相对滑动。Referring to Figures 8, 12 and 13, in some embodiments, the anti-rotation mechanism 930 can include an anti-rotation rib 931, and the anti-rotation rib 931 can slide relative to the push sleeve 241 in the first direction, so that The effect of preventing the push sleeve 241 from circumferential rotation and sliding in the first direction is taken into account. Generally speaking, an anti-rotation slot 2414 can be provided in the push sleeve 241 to match the anti-rotation rib 931, and the two slide relatively along the first direction.

在一些实施方式中，防转筋条931和防转卡槽2414形成的组合结构的数量可以是多个，同时多个防转筋条931的间隔可设置成不等，从而使得顶推套241与防转筋条931的装配位置是唯一的，保证在装配时第一顶推面2413和第二顶推面2421的稳定可靠的对 位，避免出现装配错位的情况，实现有效的机械防呆效果。In some embodiments, the number of the combined structures formed by the anti-rotation ribs 931 and the anti-rotation slots 2414 may be multiple, and the spacing of the multiple anti-rotation ribs 931 may be set at unequal intervals, so that the push sleeve 241 The assembly position with the anti-rotation rib 931 is unique, ensuring stable and reliable alignment of the first pushing surface 2413 and the second pushing surface 2421 during assembly. position to avoid assembly misalignment and achieve effective mechanical anti-fooling effect.

在一些实施方式中，可以在底座900上设置凸起的筒型件，将防转筋条931设置在筒型件的外壁上，并可以将顶推套241套接在筒型件外，实现定位和导向。可具体将筒型件与共用转轴920同轴设置。In some embodiments, a raised cylindrical member can be provided on the base 900, the anti-rotation ribs 931 can be provided on the outer wall of the cylindrical member, and the push sleeve 241 can be sleeved outside the cylindrical member to achieve Positioning and Orientation.

参见图2、图3和图4，在一些实施方式中，为了在解除连接端231与第一传动组件210的连接状态时，达到即时高效的响应，可以设置分离组件250，向传动连接组件230施加脱离第一传动组件210的作用力，从而在推杆242复位，留出足够的移动空间之后，传动连接组件230在分离组件250的作用下实现与第一传动组件210分离。Referring to Figures 2, 3 and 4, in some embodiments, in order to achieve an immediate and efficient response when the connection state of the connecting end 231 and the first transmission component 210 is released, a separation component 250 can be provided to connect the transmission component 230 to the transmission component 230. A force is applied to disengage the first transmission component 210, so that after the push rod 242 is reset and enough movement space is left, the transmission connection component 230 is separated from the first transmission component 210 under the action of the separation component 250.

在一些实施方式中，分离组件250可分别与传动连接组件230和第二传动组件220连接，从而通过推动顶推端232相对于第二传动组件220移动，促使连接端231与第一传动组件210断开连接。In some embodiments, the separation component 250 can be connected to the transmission connection component 230 and the second transmission component 220 respectively, thereby urging the push end 232 to move relative to the second transmission component 220 to urge the connection end 231 to connect with the first transmission component 210 Disconnect.

为了提升响应时效，可将分离组件设置成一弹性复位件253，持续施加促使传动连接组件230脱离第一传动组件210的作用力。在推杆242推动顶推套241和传动连接组件230与第一传动组件210连接并保持连接状态的过程中，弹性复位件253的作用力仍然存在，但是受限于推杆242、顶推套241和传动连接组件210的机械移动的强力作用，分离作用力被抵消。当推杆242改变推动顶推套241的状态，复位后移，将逐步降低推顶力，弹性复位件253的作用力将推顶传动连接组件230的连接端231脱离与第一传动组件210的连接，从而具备良好的响应时效。In order to improve the response time, the separation component can be configured as an elastic return component 253 to continuously apply force to urge the transmission connection component 230 to separate from the first transmission component 210 . When the push rod 242 pushes the push sleeve 241 and the transmission connection assembly 230 to connect and maintain the connection state with the first transmission assembly 210, the force of the elastic return member 253 still exists, but is limited by the push rod 242 and the push sleeve. 241 and the mechanical movement of the transmission connection assembly 210, the separation force is offset. When the push rod 242 changes the state of pushing the push sleeve 241 and moves backward after reset, the push force will be gradually reduced, and the force of the elastic return member 253 will separate the connecting end 231 of the push transmission connection component 230 from the first transmission component 210 connection for good response time.

在一些实施方式中，弹性复位件253可设置成弹簧，弹簧设置在顶推端232和第二传动组件220之间，持续施加使传动连接组件230脱离第一传动组件210的弹性作用力。In some embodiments, the elastic return member 253 may be configured as a spring, which is disposed between the pushing end 232 and the second transmission component 220 to continuously apply an elastic force to disengage the transmission connection component 230 from the first transmission component 210 .

The connection relationship of components 210.

A locking piece 262 can be provided at the other end of the fastening through hole to lock the headed bolt. The locking member 262 can be a pin or a nut.

在一些实施方式中，可以将连接件261设置成连接轴，连接轴一端固定于底座900上，第一传动组件210、第二传动组件220和顶推套241套设于连接轴上限制沿连接轴的 径向的脱离；止挡件263设置成挡板，挡板固设于连接轴的另一端，从而实现沿连接轴的轴向限位，止挡第一传动组件210、第二传动组件220和顶推套241沿轴向脱离。In some embodiments, the connecting member 261 can be configured as a connecting shaft.

在执行离合控制时，通过直线驱动器243动作，推动推杆242朝向顶推套241移动，推杆242头端开设的第二顶推面2421顶推第一顶推面2413，实现顶推套241沿第一方向移动，推顶连接端231向第一传动齿轮212移动，直至连接端231嵌入卡槽211内，使得第一传动齿轮212和第二传动齿轮222连接为一体，此时，直线驱动器243停留在当前位置，通过推杆242于底部900支撑顶推套241，进而支撑传动连接件，从而保持传动连接状态。当需要断开连接时，直线驱动器243复位，传动连接件的连接端231在分离组件250的作用下逐步脱离卡槽211，直至断开第一传动齿轮212与第二传动齿轮222的连接，中断动力传递路径。When executing the clutch control, the linear driver 243 acts to push the push rod 242 to move toward the push sleeve 241. The second push surface 2421 opened at the head end of the push rod 242 pushes the first push surface 2413, thereby realizing the push sleeve 241. Move along the first direction, push up the connecting end 231 and move toward the first transmission gear 212 until the connecting end 231 is embedded in the slot 211, so that the first transmission gear 212 and the second transmission gear 222 are connected as one. At this time, the linear driver 243 stays at the current position, and supports the push sleeve 241 at the bottom 900 through the push rod 242, thereby supporting the transmission connection member, thereby maintaining the transmission connection state. When the connection needs to be disconnected, the linear driver 243 is reset, and the connecting end 231 of the transmission connector gradually separates from the slot 211 under the action of the separation assembly 250, until the connection between the first transmission gear 212 and the second transmission gear 222 is disconnected. Power transmission path.

参见图1和图13，在一些实施方式中，当门体13转动到预设的开度位置时，联动齿轮300将不再驱动转门机构400动作，并停止向联动齿轮300施加驱动力以维持其转动位置，从而关闭门体13与上游驱动器件的驱动关系，避免与人工操作门体13相干涉，方便人工操作门体13。但由于冰箱等电器设备门体13上储物，或者冰箱放置偏斜等因素造成门体重心偏移，导致门体13自主偏转，从而无法维持门体13的开度，不便于使用，甚至会造成碰撞操作人员的安全风险。Referring to Figures 1 and 13, in some embodiments, when the door body 13 rotates to the preset opening position, the linkage gear 300 will no longer drive the swing door mechanism 400 and stop applying driving force to the linkage gear 300. Its rotational position is maintained, thereby closing the driving relationship between the door 13 and the upstream driving device, avoiding interference with the manual operation of the door 13, and facilitating manual operation of the door 13. However, due to factors such as storing items on the door 13 of refrigerators and other electrical equipment, or the refrigerator being placed skewed, the center of gravity of the door deviates, causing the door 13 to deflect autonomously, making it impossible to maintain the opening of the door 13, making it inconvenient to use, and even causing the door 13 to deflect. Causing safety risks to collision operators.

参见图13和图14，为了解决开关门装置停机时门体13无法维持开度的问题，可以在联动齿轮300上开设限位结构320，并在底座900上设置悬停机构600，在联动齿轮300转动到某一位置使得限位结构320与悬停机构600处于相对的状态时，悬停机构600移动而后顶抵在限位结构320上，将联动齿轮300锁定在底座900上，以制动转门机构400转动门体，能够实现门体悬停，保持预设开度位置。Referring to Figures 13 and 14, in order to solve the problem that the door body 13 cannot maintain the opening when the door opening and closing device is stopped, a limiting structure 320 can be provided on the linkage gear 300, and a hovering mechanism 600 can be provided on the base 900. When 300 rotates to a certain position so that the limiting structure 320 and the hovering mechanism 600 are in a relative state, the hovering mechanism 600 moves and then presses against the limiting structure 320, locking the linkage gear 300 on the base 900 to brake. The revolving door mechanism 400 rotates the door body, enabling the door body to hover and maintain the preset opening position.

也就是说，限位结构320跟随联动齿轮300转动，悬停机构600可相对于底座900移动，并能够响应联动齿轮300的转动改变其移动的状态，当限位结构320转到与悬停机构600匹配相对的位置时，悬停机构600可以顶抵卡紧限位结构320，锁止联动齿轮300，限制其转动，从而制动转门机构，以阻挡门体13偏转，能够保持门体13悬停在预设位置。That is to say, the limiting structure 320 follows the rotation of the linkage gear 300, and the hovering mechanism 600 can move relative to the base 900, and can change its moving state in response to the rotation of the linkage gear 300. When the limiting structure 320 rotates with the hovering mechanism When 600 matches the relative position, the hovering mechanism 600 can resist the clamping limit structure 320, lock the linkage gear 300, and limit its rotation, thereby braking the rotating door mechanism to prevent the door body 13 from deflecting, and can keep the door body 13 Hover over the preset location.

值得说明的是，悬停机构600和限位结构320的顶抵锁止状态为可逆的状态，当联动齿轮300受到的外部驱动力的作用大于悬停机构600与限位结构320之间的制动力时，联动齿轮突破顶抵限位作用，继续转动，联动齿轮300解除制动状态，可驱动转门机构400转动门体13关闭，或者也可进一步扩大门体开度。It is worth noting that the collision and locking state between the hovering mechanism 600 and the limiting structure 320 is a reversible state. When the external driving force on the linkage gear 300 is greater than the restriction between the hovering mechanism 600 and the limiting structure 320 , the locking state is reversible. When power is applied, the linkage gear breaks through the limiting effect and continues to rotate. The linkage gear 300 releases the braking state and can drive the swing door mechanism 400 to rotate the door body 13 to close, or can further expand the door opening.

参见图14和图16，在一些实施方式中，悬停机构600可包括悬停件610和推顶件620；悬停件610可移动地设置底座900上，并持续顶抵在联动齿轮300上，并且能够匹配顶抵卡紧限位结构320，在联动齿轮300使得限位结构320与悬停件610相对的状态时，悬停件610可以向联动齿轮300移动并顶抵在限位结构320上，从而将联动齿轮300锁定在底座900上，实现联动齿轮300的制动。推顶件620作为悬停件610的驱动元件，持续向悬停件610提供推顶力，将悬停件610向联动齿轮300向联动齿轮300推顶，从而可推顶悬停件610与限位结构320的实现联动齿轮300的顶抵制动。Referring to Figures 14 and 16, in some embodiments, the hovering mechanism 600 may include a hovering member 610 and a pushing member 620; the hovering member 610 is movably disposed on the base 900 and continues to press against the linkage gear 300. , and can be matched against the clamping limiting structure 320. When the linkage gear 300 makes the limiting structure 320 and the hovering member 610 face each other, the hovering member 610 can move toward the linkage gear 300 and press against the limiting structure 320. , thereby locking the linkage gear 300 on the base 900 to realize braking of the linkage gear 300 . As the driving element of the hovering component 610, the ejection component 620 continuously provides ejection force to the hovering component 610, pushing the hovering component 610 towards the linkage gear 300, thereby ejecting the hovering component 610 and the limiter. The bit structure 320 realizes the resistance resistance of the linkage gear 300 .

需要说明的是，悬停件610在持续推顶力的作用下，始终保持与联动齿轮300的顶抵状态，在联动齿轮300转动过程中，悬停件610可以在联动齿轮300上滑动；仅在联动齿轮300转动到使限位结构320与悬停机构600相对的状态的情况下，在推顶力的作用下悬停件610移动并顶抵于限位结构320内，制动联动齿轮300。通过持续的推顶力使得悬停件610能够跟踪联动齿轮300的转动位置，高时效响应限位结构320的到位状态，即限位结构320与悬停机构600对位后，悬停件610即刻顶抵卡紧限位结构320。在悬停件 610上可设置顶抵部611，用于接触顶抵限位结构320，并可具体通过顶抵进限位结构320的内部，实现接触顶抵制动。It should be noted that the hovering member 610 always maintains a state of pushing against the linkage gear 300 under the action of the continuous pushing force. During the rotation of the linkage gear 300, the hovering member 610 can slide on the linkage gear 300; only When the linkage gear 300 rotates to a state where the limiting structure 320 is opposite to the hovering mechanism 600, the hovering member 610 moves and presses against the limiting structure 320 under the action of the pushing force, and the linkage gear 300 is braked. . Through the continuous pushing force, the hovering part 610 can track the rotation position of the linkage gear 300 and respond to the positioning state of the limiting structure 320 with high efficiency. That is, after the limiting structure 320 and the hovering mechanism 600 are aligned, the hovering part 610 immediately Push against the clamping limiting structure 320. on hover A resisting portion 611 can be provided on the 610 for contacting against the limiting structure 320, and specifically by pushing against the inside of the limiting structure 320 to achieve contact resisting.

参见图15，在一些实施方式中，限位结构320可设置成位于联动齿轮300周面上的凹槽，相配合的，悬停件610的顶抵部611可设置成与凹槽的槽型匹配的形态，且保证顶抵部611可卡嵌进入和脱离凹槽，以便于顶抵部611顺利卡紧制动和脱离解除制动。Referring to FIG. 15 , in some embodiments, the limiting structure 320 can be configured as a groove on the peripheral surface of the linkage gear 300 , and accordingly, the abutment portion 611 of the hovering member 610 can be configured to match the shape of the groove. The matching shape ensures that the abutting part 611 can be inserted into and disengaged from the groove, so that the abutting part 611 can smoothly clamp and brake and disengage and release the brake.

值得说明的是，凹槽的槽口可设置用于平滑衔接联动齿轮300的周面的衔接面，便于顶抵部611相对于联动齿轮300的周面顺畅滑动进入凹槽和自凹槽顺畅脱离，从而在实施制动和解除制动时，均能够舒畅稳定达成。It is worth noting that the notch of the groove can be provided with a connecting surface for smoothly connecting the peripheral surface of the linkage gear 300, so that the abutment portion 611 can smoothly slide into the groove relative to the peripheral surface of the linkage gear 300 and smoothly escape from the groove. , so that it can be achieved comfortably and stably when braking and releasing the brake.

在一些实施方式中，凹槽的槽型可设置成C型或者V型，相应地，顶抵部611也设置成可嵌入的圆弧形或者尖塔形结构。In some embodiments, the groove shape of the groove can be set in a C-shape or a V-shape, and accordingly, the abutment portion 611 is also set in an embeddable arc-shaped or spire-shaped structure.

为了便于顶抵部611顺利脱离凹槽，顶抵部611可以与凹槽之间留有一定的间隙，即，当顶抵部611卡嵌入凹槽内时，顶抵部611的部分区域顶抵在凹槽内壁上，另一部分区域与槽壁之间形成间隙，在保证卡紧的前提下，也便于受到略大于推顶力时，顶抵部611可以顺利脱离。In order to facilitate the resisting portion 611 to escape from the groove smoothly, a certain gap can be left between the resisting portion 611 and the groove. That is, when the resisting portion 611 is inserted into the groove, a part of the resisting portion 611 resists the groove. On the inner wall of the groove, a gap is formed between another part of the area and the groove wall. Under the premise of ensuring the clamping, it is also convenient for the resisting portion 611 to be detached smoothly when the pushing force is slightly greater than the pushing force.

参见图14和图18，在一些实施方式中，考虑到推顶力及其作用效果的稳定性对顶抵部611的制动性能有着积极效果，可在悬停件610上开设推顶限位槽612，将推顶件620设置在推顶限位槽612内从而使得推顶件620和悬停件610之间保持相对稳定的连接状态，一定程度上能够降低两者相对摆动的幅度，从而保持顶抵部611的受力方向、移动方向以及顶抵部611与限位结构320的接触区域的稳定，保证制动效果。Referring to Figures 14 and 18, in some embodiments, considering that the stability of the pushing force and its effect has a positive effect on the braking performance of the pushing portion 611, a pushing limit can be provided on the hovering member 610 Groove 612, the ejection part 620 is arranged in the ejection limiting groove 612, so that the ejection part 620 and the hovering part 610 can maintain a relatively stable connection state, and the relative swing amplitude of the two can be reduced to a certain extent, thereby Maintain the stability of the direction of force and movement of the resisting portion 611 and the contact area between the resisting portion 611 and the limiting structure 320 to ensure the braking effect.

在一些实施方式中，推顶件620也可与顶推部611直接连接，将推顶力的作用点集中在推顶部611上，从而降低由于悬停件610自身的姿态变化导致的顶推力的方向偏移和顶抵效果不稳定的风险。In some embodiments, the ejection part 620 can also be directly connected to the ejection part 611 to concentrate the action point of the ejection force on the ejection part 611, thereby reducing the ejection force caused by the attitude change of the hovering part 610 itself. Risk of directional deviation and unstable resistance effect.

值得说明的是，推顶限位槽612与推顶件620的大小规格可进行匹配设计，使得推顶限位槽612的规格可略大于推顶件620的宽度，缩小相对摆动的空间，保持推顶力的方向的稳定。It is worth noting that the size specifications of the ejection limit groove 612 and the ejection member 620 can be designed to match, so that the size of the ejection limit groove 612 can be slightly larger than the width of the ejection member 620, thereby reducing the relative swing space and maintaining Stability in the direction of the ejection force.

在一些实施方式中，推顶限位槽612可以设置成沿推顶力方向且可容纳推顶件620的盲孔，孔底设置在推顶部611上，形成对推顶件620的周向限位，从而能够限制周向摆动幅度，降低悬停件610受力弹起的风险，保证顶推位置和姿态的稳定。In some embodiments, the ejection limiting groove 612 can be provided as a blind hole along the direction of the ejection force and capable of accommodating the ejection member 620 . The bottom of the hole is provided on the ejection top portion 611 to form a circumferential limit to the ejection member 620 . position, thereby limiting the circumferential swing range, reducing the risk of the hovering component 610 springing up due to force, and ensuring the stability of the pushing position and attitude.

在一些实施方式中，悬停件610的一端可以设置顶抵部611，用于接触顶抵限位结构320，悬停件610的另一端还可设置连接部，用于连接推顶件620，从而便于悬停件的成型加工，简化工艺流程。In some embodiments, one end of the hovering member 610 may be provided with a resisting portion 611 for contacting the limiting structure 320, and the other end of the hovering member 610 may be provided with a connecting portion for connecting to the ejection member 620. This facilitates the forming and processing of hovering parts and simplifies the process flow.

在一些实施方式中，推顶件620可以设置成弹性件，从而通过弹性件的弹性形变施加持续且连续的推顶力，保证悬停件610以简洁的结构高时效响应联动齿轮300的转动位置变化，能够在限位结构320到位时，迅速顶抵入限位结构320内。同时，弹性件的弹性形变的稳定性使得其施加到悬停件610上的顶推力也能够保持稳定状态，一方面能够保持悬停状态的稳定，另一方面，还能够使联动齿轮300在一个相对稳定且可控的驱动力的作用下转动并解除制动状态，从而实现开关门装置的悬停功能的稳定性、可靠性以及可平滑顺畅地实现的性能。In some embodiments, the ejection member 620 can be configured as an elastic member, thereby exerting a continuous and continuous ejection force through the elastic deformation of the elastic member, ensuring that the hovering member 610 responds to the rotational position of the linkage gear 300 with a simple structure and high efficiency. Change, when the limiting structure 320 is in place, it can quickly push into the limiting structure 320. At the same time, the stability of the elastic deformation of the elastic member enables the pushing force exerted on the hovering member 610 to remain stable. On the one hand, it can maintain the stability of the hovering state, and on the other hand, it can also make the linkage gear 300 move in a stable state. It rotates and releases the braking state under the action of relatively stable and controllable driving force, thereby achieving stability, reliability and smooth performance of the hovering function of the door opening and closing device.

鉴于弹性件的形变可分为压缩形变和拉伸形变，弹性件应当以相对稳定且线性的形变状态为原则设置装配方式。Since the deformation of elastic parts can be divided into compression deformation and tensile deformation, the assembly method of elastic parts should be set based on the principle of relatively stable and linear deformation state.

在弹性件为压缩态提供弹性的推顶力时，悬停件610可以设置在弹性件和联动齿轮300的周面之间，将弹性件压缩布置在底座900和悬停件610之间，并保持形变复位方向与推顶力方向一致，从而将弹性件的弹性推力转化为稳定的弹性推顶力输出。When the elastic member provides elastic pushing force for the compressed state, the hovering member 610 can be disposed between the elastic member and the peripheral surface of the linkage gear 300, and the elastic member is compressed and arranged between the base 900 and the hovering member 610, and Keep the deformation reset direction consistent with the direction of the ejection force, thereby converting the elastic thrust of the elastic member into a stable elastic ejection force output.

在弹性件为拉伸态提供弹性的推顶力时，可将弹性件拉伸设置在底座900和悬停件610之间，并保持形变复位方向与推顶力方向一致，从而将弹性件的弹性拉力转化为稳定的弹性推顶力输出。When the elastic member provides elastic ejection force in the stretched state, the elastic member can be stretched and arranged between the base 900 and the hovering member 610, and the deformation reset direction can be kept consistent with the direction of the ejection force, so that the elastic member can be stretched. The elastic pulling force is converted into a stable elastic pushing force output.

在一些实施方式中，弹性件为弹簧，并可具体设置成压簧或者拉簧，从而通过压 缩形变或者拉伸形变提供稳定的推顶力。具体可将压簧压缩在悬停件610和底座900之间，或者可将拉簧拉伸连接在悬停件610和底座900之间。In some embodiments, the elastic member is a spring, and can be specifically configured as a compression spring or a tension spring, so that by compression Contraction deformation or tensile deformation provides stable ejection force. Specifically, a compression spring can be compressed between the hovering component 610 and the base 900 , or a tension spring can be stretched and connected between the hovering component 610 and the base 900 .

参见图17和图18，可具体将压簧的第一端顶抵在推顶部611上，在底座900上设置与弹簧大致等高的凸台部909，并将弹簧的第二端顶抵在凸台部909上，保持压簧在其轴向上的平直姿态，以形成稳定可靠的推顶力。Referring to Figures 17 and 18, the first end of the compression spring can be pressed against the push top 611, a boss portion 909 approximately the same height as the spring can be provided on the base 900, and the second end of the spring can be pressed against the push top 611. On the boss portion 909, the compression spring is maintained in a straight posture in its axial direction to form a stable and reliable ejection force.

可具体将拉簧的第一端固定在推顶件610的主体上，或者直接固定在推顶部611上，并将拉簧的第二端固定在底座900上设置的凸台部909上，并尽量拉簧与底座900的板面持平并保持平直姿态，以形成稳定可靠的推顶力。Specifically, the first end of the tension spring can be fixed on the main body of the ejection member 610, or directly fixed on the ejection portion 611, and the second end of the tension spring can be fixed on the boss portion 909 provided on the base 900, and the tension spring should be kept flush with the plate surface of the base 900 and in a straight posture as much as possible to form a stable and reliable ejection force.

在一些实施方式中，还可在凸台部909的下方设置支撑槽908用于限位支撑上述弹簧，从而保证其顶抵位置的稳定，避免晃动。In some embodiments, a support groove 908 can also be provided below the boss portion 909 to limit and support the spring, thereby ensuring the stability of its pressing position and avoiding shaking.

在一些实施方式中，也可采用如扭簧，簧片等类型的弹性件，满足弹力方相与悬停件610的移动方向大致吻合即可，此处不再赘述。In some embodiments, elastic members such as torsion springs and reeds may also be used, as long as the elastic force phase is roughly consistent with the moving direction of the hovering member 610, which will not be described again here.

在一些实施方式中，为了维持悬停件610的移动方向的稳定，限制过度摆动和振动，可在底座900上设置悬停限位滑槽906，并将悬停件设置在悬停限位滑槽906内，通过悬停限位滑槽906的侧壁的导向和约束作用，保持悬停件610的移动方向的稳定，进而保证制动性能的可靠性。In some embodiments, in order to maintain the stability of the moving direction of the hovering member 610 and limit excessive swing and vibration, a hovering limit chute 906 may be provided on the base 900 and the hovering member may be disposed on the hovering limit slide. In the groove 906, the moving direction of the hovering member 610 is kept stable through the guiding and constraining functions of the side walls of the hovering limit chute 906, thereby ensuring the reliability of the braking performance.

参见图17，在一些实施方式中，悬停限位滑槽906可以为两个相对的限位凸台907之间的间隙，且限位凸台907在悬停件610移动方向上具备一定的长度，满足滑动行程内的限位即可。还可以在两个限位凸台907的顶部连接上限位结构，一定程度上可以限制其脱离底座900；还可在底座900的上盖上设置相应的上限位结构，与悬停限位滑槽906相对，从而实现上限位的目的，使得悬停件610能够始终以稳定的方向移动，保证制动性能的可靠性。Referring to Figure 17, in some embodiments, the hovering limiting chute 906 can be a gap between two opposing limiting bosses 907, and the limiting boss 907 has a certain gap in the moving direction of the hovering member 610. The length is sufficient to meet the limit within the sliding stroke. An upper limit structure can also be connected to the top of the two limit bosses 907, which can limit their separation from the base 900 to a certain extent; a corresponding upper limit structure can also be set on the upper cover of the base 900, in conjunction with the hovering limit chute. 906 relative to each other, thereby achieving the purpose of upper limit, so that the hovering member 610 can always move in a stable direction, ensuring the reliability of braking performance.

在一些实施方式中，为了保持悬停件610的移动方向的稳定，限制不稳定摆动，可以将悬停件610设置成杆状，顶抵部611设置在其靠近联动齿轮300的一端；即具备一定长度的长条形结构件，配合悬停限位滑槽906实现稳定滑动，利用其长度特征和悬停限位滑槽906的对长条形结构件径向限位效果，一定程度上降低摆动幅度。悬停限位滑槽906和杆状的悬停件610在推顶力方向上的长度越长，限制摆动幅度的性能越好，悬停件610的移动方向越稳定。In some embodiments, in order to maintain the stability of the moving direction of the hovering member 610 and limit unstable swings, the hovering member 610 can be configured in a rod shape, and the resisting portion 611 is provided at one end thereof close to the linkage gear 300; that is, having A long strip structural member of a certain length cooperates with the hovering limit chute 906 to achieve stable sliding. By utilizing its length characteristics and the radial limiting effect of the hovering limit chute 906 on the long strip structural member, it reduces the risk to a certain extent. swing amplitude. The longer the length of the hovering limit chute 906 and the rod-shaped hovering member 610 in the direction of the ejection force, the better the performance of limiting the swing amplitude, and the more stable the moving direction of the hovering member 610 is.

参见图21，在一些实施方式中，悬停机构600还可设置成悬停连接件630和悬停限位槽640相配合的卡合制动结构，悬停连接件630连接在联动齿轮300上，悬停限位槽640设置在底座900上，联动齿轮300转动以带动悬停连接件630与悬停限位槽640卡合，以制动转门机构400转动门体13。Referring to Figure 21, in some embodiments, the hovering mechanism 600 can also be configured as an engaging braking structure in which the hovering connector 630 and the hovering limiting groove 640 cooperate. The hovering connector 630 is connected to the linkage gear 300. , the hovering limit groove 640 is provided on the base 900 , and the linkage gear 300 rotates to drive the hovering connector 630 to engage with the hovering limit groove 640 to brake the swing door mechanism 400 to rotate the door body 13 .

容易理解的是，联动齿轮300逆时针转动为悬停卡合方向，在联动齿轮300转动时，悬停连接件630可顺利的卡嵌进悬停限位槽640，将联动齿轮300与底座900连接一体，从而实现联动齿轮300以及与之相连的转门机构400的制动。It is easy to understand that the linkage gear 300 rotates counterclockwise to the hovering engaging direction. When the linkage gear 300 rotates, the hovering connector 630 can be smoothly inserted into the hovering limit groove 640 to connect the linkage gear 300 to the base 900 Integrated connection enables braking of the linkage gear 300 and the rotating door mechanism 400 connected thereto.

值得说明的是，悬停限位槽640可以与悬停连接件630进行位置匹配设置，使得其能够逆时针方向卡入但相对难以逆时针脱出，而是容易顺时针脱出，从而实现稳定可靠的卡入和脱出。It is worth mentioning that the hovering limit groove 640 can be positioned to match the hovering connector 630, so that it can be inserted in the counterclockwise direction but relatively difficult to come out counterclockwise, but is easy to come out clockwise, thereby achieving stable and reliable operation.
