Description

Technical Field

[0001] This invention relates to the field of household appliance manufacturing technology, and in particular to a bridging component. Background Technology

[0002] In related technologies, robotic vacuum cleaners can be used to clean rooms in place of users. However, balconies and bathrooms often have thresholds that robotic vacuum cleaners cannot pass through. Installing a bridging component at the threshold can create a "bridge" connecting the floor and the threshold, allowing the robotic vacuum cleaner to pass through. In existing technologies, the bridging component covers the threshold under the weight of the robotic vacuum cleaner. After the robotic vacuum cleaner passes through the bridging component, it flips away from the threshold to allow the sliding door to open and close normally. However, the flipped-over bridging component occupies space above the threshold, causing inconvenience to the user and reducing the user experience. Summary of the Invention

[0005] The bridging assembly according to the present invention is provided with a flip plate so that when the sliding door assembly is opened, the bridging assembly is in the bridging position, the flip plate covers the threshold and does not occupy the space above the threshold, and when the sliding door assembly is closed, the flip plate moves away from the threshold so that the door can close normally. Such a bridging assembly is convenient to use and can improve the user experience.

[0006] According to some embodiments of the present invention, a movable door is provided on the threshold, the door moves in a first direction to realize the closing action, and the door contacts the triggering part during the closing process and triggers the flip plate to flip from the bridging position to the avoidance position.

[0007] According to some embodiments of the present invention, the flip plate is connected to the climbing frame via a pivot shaft extending in a first direction; wherein the trigger portion is formed on at least one side of the flip plate in the width direction, the trigger portion being configured as an inclined surface inclined toward the first direction in a radial direction away from the pivot shaft.

[0008] According to some embodiments of the present invention, the door body moves toward a second direction to realize the door opening action, a flange is formed on the trigger part, the flange extends toward the second direction, and the angle between the flange and the flip plate is a right angle or an obtuse angle.

[0009] According to some embodiments of the present invention, an arc-shaped transition section is formed between the flange and the flip plate.

[0010] According to some embodiments of the present invention, the bridging assembly further includes: a connecting portion disposed on the climbing frame; and a pivot shaft passing through the connecting portion to rotatably connect the flip plate to the climbing frame.

[0011] According to some embodiments of the present invention, the connecting portion is formed with a first mounting hole extending through the width direction of the climbing frame, the flip plate is formed with a mating portion on the edge facing the connecting portion, the mating portion is formed with a second mounting hole, and the pivot shaft passes through the first mounting hole and the second mounting hole in sequence to flip the flip plate and the connecting portion in a rotatable connection.

[0012] According to some embodiments of the present invention, the mating parts are disposed on both sides in the width direction of the flip plate, and the upper surface of the climbing frame is formed with a clearance groove for accommodating the mating parts.

[0013] According to some embodiments of the present invention, the bridging assembly further includes: a backstop, the backstop being disposed on the ramp and adapted to restrict the movement of the ramp when the ramp is flipped to the avoidance position.

[0014] According to some embodiments of the present invention, the upper surface of the ramp is formed with a clearance groove for accommodating the mating part, the clearance groove extending in the direction toward the threshold, and the sidewall of the clearance groove extending in the height direction is configured as the anti-reverse part.

[0019] In summary, the bridging assembly of the present invention, by setting a flip plate, ensures that the bridging assembly is in the bridging position when the sliding door assembly is open, at which time the flip plate covers the threshold and does not occupy the space above the threshold. When the sliding door assembly is closed, the flip plate moves away from the threshold so that the door can close normally. Such a bridging assembly is convenient to use and can improve the user experience. The edge of the flip plate is inclined and has a flange, which makes it easy for the force of the door to drive the flip plate away from the threshold.

The ramp frame is provided with multiple first mounting holes. By adjusting the cooperation position between the pivot shaft and the first mounting holes, the cooperation position between the flip plate and the ramp frame can be adjusted, thereby adjusting the length of the flip plate extending out of the ramp frame to adapt to the threshold width. In addition, the bottom of the ramp frame is provided with a support foot. By rotating the support foot, the tilt angle of the ramp frame can be adjusted to adapt to the threshold height. Such a bridging assembly can adapt to thresholds of various sizes. The bridging assembly is also provided with a stop part to prevent the flip plate from over-flipping, so that the flip plate can automatically flip from the avoidance position to the bridging position.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0035] In related technologies, robotic vacuum cleaners can be used to clean rooms in place of users. However, balconies and bathrooms often have thresholds that robotic vacuum cleaners cannot pass through. Installing a bridging component at the threshold can create a "bridge" connecting the floor and the threshold, allowing the robotic vacuum cleaner to pass through. In existing technologies, the bridging component covers the threshold under the weight of the robotic vacuum cleaner. After the robotic vacuum cleaner passes through the bridging component, it flips away from the threshold to allow the sliding door to open and close normally. However, the flipped-over bridging component occupies space above the threshold, causing inconvenience to the user and reducing the user experience.

[0036] The following is for reference. Figures 1-4 A bridging assembly 1 according to an embodiment of the present invention is described.

[0037] like Figures 1-2As shown, the bridging assembly 1 according to the present invention includes: a ramp frame 10 and a flip plate 20. The ramp frame 10 is disposed on one side of the threshold 3, and a support surface 11 is formed on the upper surface of the ramp frame 10; the flip plate 20 is configured to have a clearance position and a bridging position, and the flip plate 20 is rotatably disposed on the support surface 11 to switch between the clearance position and the bridging position. A trigger portion is formed on the edge of the flip plate 20, and the trigger portion is adapted to flip from the bridging position to the clearance position after being triggered. Specifically, there is a height difference between the threshold 3 and the ground. The ramp frame 10 is disposed on one side of the threshold 3 to connect the ground and the top of the threshold 3, thereby forming a road from the ground on one side of the threshold 3 to the top of the threshold 3. The bridging assembly 1 enables the construction of a road from the ground to the top of the threshold 3. More specifically, the ramp 10 is set on the ground and located on one side of the threshold 3. The ramp 10 can be constructed as a structure that transitions from the ground to the threshold 3 in the height direction. A support surface 11 is formed on the upper surface of the ramp 10, and the support surface 11 is suitable for installing the flip plate 20. At least part of the flip plate 20 covers the top of the threshold 3 to build a road from the ramp 10 to the top of the threshold 3. At this time, the flip plate 20 is in a bridging position, and the robot vacuum cleaner can pass through the threshold 3 through the flip plate 20. When the door 2 moves to the threshold 3, the door 2 contacts the trigger part of the flip plate 20 to make the flip plate 20 flip. The flip plate 20 flips and leaves the top of the threshold 3. At this time, the flip plate 20 is in an avoidance position so that the door 2 and the threshold 3 can cooperate to achieve normal closing of the door 2.

[0038] In some embodiments, the door body 2 and the threshold 3 constitute a sliding door assembly, which has an open state and a closed state. The door body 2 is movably disposed on the threshold 3 and moves along the threshold 3 in a first direction or a second direction. When the sliding door assembly is in the open state, there is no contact between the door body 2 and the bridging assembly 1. The flip plate 20 is in the bridging position, and the flip plate 20 overlaps the top of the threshold 3 and together with the ramp frame 10, forms a road from the ground on one side of the threshold 3 to the top of the threshold 3. When the sliding door assembly switches from the open state to the closed state, the door body 2 moves along the threshold 3 in the first direction. At this time, the surface of the door body 2 in the first direction contacts the flip plate 20, thereby driving the flip plate 20 to flip, so that the flip plate 20 leaves the top of the threshold 3. At this time, the flip plate 20 flips from the bridging position to the avoidance position, and the road built by the bridging assembly 1 is broken, so that the door body 2 can pass smoothly and close. At this time, the flip plate 20 leans against the door body 2, and the sliding door assembly is in the closed state. When the sliding door assembly switches from the closed state to the open state, the door body 2 moves along the threshold 3 in the second direction. After the door body 2 moves, the flip plate 20 leaning against the surface of the door body 2 flips under its own weight and resets to overlap the top of the threshold 3. At this time, the sliding door assembly is in the open state, and the bridging assembly 1 rebuilds the road from the ground to the top of the threshold 3.

[0039] According to the present invention, the bridging assembly 1 is provided with a flip plate 20 so that when the sliding door assembly is opened, the bridging assembly 1 is in the bridging position, the flip plate 20 covers the threshold 3 and does not occupy the space above the threshold 3, and when the sliding door assembly is closed, the flip plate 20 leaves the threshold 3 so that the door 2 can close normally. Such a bridging assembly 1 is convenient to use and can improve the user experience.

[0040] According to some embodiments of the present invention, such as Figure 1 As shown, a movable door 2 is provided on the threshold 3. The door 2 moves in the first direction to achieve a closing action. During the closing process, the door 2 contacts the triggering part and triggers the flip plate 20 to flip from the bridging position to the avoidance position. Specifically, as shown... Figure 1 As shown, the flip plate 20 has a length direction and a width direction, and the width direction of the flip plate 20 is consistent with the moving direction of the door body 2. When the door body 2 moves toward the first direction, it contacts the edge of the flip plate 20 in the width direction, i.e., the trigger part, so that the flip plate 20 flips from the bridging position to the avoidance position, thereby switching the sliding door assembly from the open state to the closed state, and the door body 2 realizes the closing action.

[0041] According to some embodiments of the present invention, the flip plate 20 is connected to the ramp 10 via a pivot 30 extending in a first direction; wherein at least one side of the flip plate 20 in the width direction is formed with a trigger portion, the trigger portion being configured as an inclined surface (not shown in the figure) arranged radially away from the pivot 30 and inclined toward the first direction. Specifically, the end of the flip plate 20 in the width direction is formed with a trigger portion. When the door 2 moves toward the first direction, the door 2 contacts the trigger portion, and the flip plate 20 flips about the side connected to the pivot 30 as an axis. The side of the flip plate 20 connected to the pivot 30 is configured as one side of the flip plate 20 in the length direction, and the flip plate 20 flips about the side connected to the pivot 30 in the length direction as an axis. More specifically, the trigger portion is configured as an inclined surface and is inclined radially away from the pivot 30 toward the first direction, so that when the door 2 moves in the first direction and contacts the trigger portion, a force is applied to the inclined surface. A component of this force perpendicular to the inclined surface drives the flip plate 20 to flip away from the threshold 3.

[0042] According to some embodiments of the present invention, such as Figure 1 As shown, the door 2 moves in the second direction to achieve the opening action. A flange 21 is formed on the trigger part, extending in the second direction. The angle between the flange 21 and the flip plate 20 is a right angle or an obtuse angle. Specifically, the flip plate 20 has a trigger part formed on at least one edge in the width direction, and a flange 21 suitable for contacting the door 2 is formed on the trigger part. The flange 21 can increase the contact area between the door 2 and the flip plate 20, such as... Figure 1As shown, the width direction of the flip plate 20 is consistent with the width direction of the climbing frame 10 and the direction of movement of the door 2. A flange 21 is provided on the edge of the flip plate 20 in the width direction so that the contact area between the door 2 and the flip plate 20 is larger. The flange 21 protrudes from the trigger part and is inclined in the second direction. After the door 2 contacts the flange 21, the component of the force applied to the flange 21 can drive the flip plate 20 to flip.

[0043] More specifically, when the angle between the flange 21 and the flip plate 20 is a right angle, the contact area between the door body 2 and the flange 21 is larger. When the angle between the flange 21 and the flip plate 20 is an obtuse angle, the flange 21 can protrude from the triggering part in the second direction so that the door body 2 can contact the flange 21 when moving in the first direction. After the flip plate 20 overlaps the top of the threshold 3, the flange 21 can be triggered by the closing action to flip the flip plate 20 to move away from the threshold 3, thereby flipping the flip plate 20 from the bridging position to the avoidance position. When the door closes, the door body 2 moves in the first direction. The angle between the flange 21 and the second direction is designed to be a right angle or an obtuse angle to decompose and utilize the force applied by the door body 2 to flip the rotating plate 20. The force applied by the door body 2 acts on the flange 21. Due to the inclined setting of the flange 21, the force applied to the flange 21 can be decomposed into multiple component forces in multiple directions. One of these component forces causes the rotating plate 20 to flip and rotate away from the threshold 3. The force applied by the door body 2 to the flange 21 can cause the rotating plate 20 to flip away from the threshold 3. The flange 21 is set at the edge of the rotating plate 20 to facilitate the door body 2 to drive the rotating plate 20 away from the threshold 3. The principle is simple and reliable, highly feasible, and requires little user operation, thus improving the user experience.

[0044] In some embodiments, the door can move in a first direction to achieve a closing action, while moving in a second direction can achieve a opening action. The first direction and the second direction are opposite, and the door moves in either the first direction or the second direction. The width direction of the flip plate 20 is consistent with the direction of door movement. One side of the flip plate 20 in the length direction is connected to the ramp frame 10. The flip plate 20 and the ramp frame 10 are connected by a pivot shaft 30. At least one edge of the flip plate 20 in the width direction has a trigger portion. The trigger portion is constructed as an inclined surface that is inclined in the first direction in the radial direction away from the pivot shaft 30. A flange 21 extending in the second direction is formed on the trigger portion.

[0045] In other embodiments, both sides of the flip panel 20 in the width direction are formed with flanges 21, and such a bridging assembly 1 can be applied to a double-sided sliding door assembly with two door bodies 2.

[0046] According to some embodiments of the present invention, such as Figures 1-3As shown, an arc-shaped transition section 211 is formed between the flange 21 and the flip plate 20. Specifically, the flange 21 is formed on the edge of the flip plate 20 in the width direction, and an arc-shaped transition section 211 is formed between the flange 21 and the flip plate 20 to prevent the flange 21 from getting stuck in the door body 2 and to ensure that the door body 2 can open and close normally.

[0047] In some embodiments, such as Figure 3 As shown, the length of the portion of the flip plate 20 with the flange 21 is consistent with the thickness of the door body 2, so as to ensure that there is sufficient contact area between the door body 2 and the flange 21, so that the door body 2 can apply force to the flange 21, avoid the door body 2 from being stuck by the flange 21 when it moves, and ensure that the door closes smoothly.

[0048] In some embodiments, the flip plate 20 should be made of a material with high hardness to prevent deformation of the flip plate 20 caused by the force applied when the door 2 is closed. Deformation of the flip plate 20 would prevent it from flipping from the bridging position to the avoidance position. Simultaneously, the surface of the flip plate 20 should have high friction to ensure that the robot vacuum cleaner does not slip when passing through, ensuring the safety of the bridging assembly 1 during use and ensuring that the robot vacuum cleaner can operate more stably and reliably. The robot vacuum cleaner travels from the ground to the ramp 10. The flip plate 20 is located on one side of the ramp 10 in the length direction and overlaps the top of the threshold 3. The robot vacuum cleaner moves along the length direction of the ramp 10 to the flip plate 20, thereby passing through the threshold 3.

[0049] In some embodiments, the flip panel 20 uses a two-color injection molding process of plastic and rubber to ensure safety during use. For example, the flip panel 20 is made of TPE (Thermoplastic Elastomer) material. TPE has the characteristics of high strength, high resilience, injection molding, soft touch, wide range of applications, environmental protection, non-toxic and safe, excellent processing performance, and can be recycled to reduce costs.

[0050] According to some embodiments of the present invention, such as Figures 1-3 As shown, the bridging assembly 1 also includes a connecting part and a pivot shaft 30. The connecting part is disposed on the climbing frame 10; the pivot shaft 30 passes through the connecting part to rotatably connect the flip plate 20 to the climbing frame 10. Specifically, the flip plate 20 is rotatably disposed on the climbing frame 10 via the pivot shaft 30, wherein the climbing frame 10 is provided with a connecting part, and the pivot shaft 30 can pass through the connecting part to pivotally connect the climbing frame 10 and the flip plate 20.

[0051] According to some embodiments of the present invention, such as Figures 1-3As shown, the connecting portion has a first mounting hole 121 extending through the width of the ramp frame 10. A mating portion is formed on the edge of the flip plate 20 facing the connecting portion, and a second mounting hole is formed on the mating portion. The pivot shaft 30 passes through the first mounting hole 121 and the second mounting hole in sequence to rotatably connect the flip plate 20 to the connecting portion. Specifically, the connecting portion of the ramp frame 10 has a first mounting hole 121 formed in the width direction of the ramp frame 10, and the mating portion of the flip plate 20 has a second mounting hole formed in the width direction of the flip plate 20. The pivot shaft 30 passes through the first mounting hole 121 and the second mounting hole in sequence to rotatably connect the flip plate 20 to the connecting portion.

[0052] In some embodiments, since the pivot shaft 30 needs to pass through the first mounting hole 121 and the second mounting hole in sequence, at least a portion of the connecting portion having the first mounting hole 121 should avoid each other with at least a portion of the mating portion having the second mounting hole.

[0053] According to some embodiments of the present invention, such as Figure 4 As shown, mating parts are provided on both sides of the flip plate 20 in the width direction, and the upper surface of the climbing frame 10 has a clearance groove 13 for accommodating the mating parts. Specifically, the mating parts are provided on both sides of the flip plate 20 in the width direction. When the climbing frame 10 mates with the flip plate 20, the connecting part should be located between the two mating parts so that the pivot shaft 30 passes through the first mounting hole 121 and the second mounting hole in sequence. More specifically, the connecting part is provided on at least a portion of the climbing frame 10 in the width direction, and a clearance groove 13 is also formed on the surface of the climbing frame 10 where the connecting part is provided. The clearance groove 13 is adapted to accommodate the mating parts so that the flip plate 20 can flip.

[0054] According to some embodiments of the present invention, such as Figure 4 As shown, the bridging assembly 1 also includes a stop part 14, which is disposed on the ramp frame 10 and is adapted to restrict the movement of the flip plate 20 when the flip plate 20 is flipped to the avoidance position. Specifically, in order to prevent the flip plate 20 from over-flipping during the process of the sliding door assembly switching from the open state to the closed state, so that it cannot be flipped back to its original position due to its own gravity, the stop part 14 should be provided to limit the flip angle of the flip plate 20.

[0055] According to some embodiments of the present invention, such as Figure 4 As shown, the upper surface of the ramp frame 10 has a clearance groove 13 for accommodating the mating part. The clearance groove 13 extends through the sill 3, and a stop part 14 is disposed on the side wall of the clearance groove 13 extending in the height direction. Specifically, the stop part 14 is provided in the clearance groove 13. When the flip plate 20 flips, the mating part flips along with the flip plate 20. Since the mating part is accommodated in the clearance groove 13, when the mating part flips to contact the stop part 14, it can restrict the flip plate 20 from continuing to flip, thereby limiting the angle of flipping of the flip plate 20.

[0056] According to some embodiments of the present invention, such as Figure 4 As shown, the sidewall of the clearance groove 13 extending in the height direction is arc-shaped, and the angle between the sidewall and the bottom wall of the clearance groove 13 is α, where α satisfies: 0°<α≤90°. Specifically, the anti-reverse part 14 is provided in the clearance groove 13 and is constructed as the sidewall of the clearance groove 13 extending in the height direction. The angle between the sidewall and the bottom wall of the clearance groove 13 should not be greater than 90° to avoid excessive flipping of the flipping plate 20.

[0057] According to some embodiments of the present invention, such as Figure 3 As shown, the first mounting holes 121 are configured as a plurality of holes arranged parallel to each other along the length of the connecting portion. Specifically, the threshold 3 has a height direction, a thickness direction, and a width direction that are orthogonal to each other. The thickness direction of the threshold 3 is consistent with the length direction of the ramp 10. The direction of movement of the door body 2 is consistent with the width direction of the threshold 3 and the width direction of the ramp 10. The ramp 10 is configured as a structure that transitions from the ground to the threshold 3 in the height direction. The support surface 11 of the ramp 10 has an angle with the ground. The length direction of the connecting part is consistent with the length direction of the ramp 10, that is, the length direction of the connecting part is orthogonal to the moving direction of the door 2. Since the first mounting holes 121 are constructed to be multiple and arranged parallel to each other in the length direction of the connecting part, the pivot shaft 30 can be selectively matched with any one of the first mounting holes 121 to adjust the position of the flip plate 20. Therefore, when the angle between the support surface 11 and the ground remains unchanged, in order to adapt to different thicknesses of the threshold 3, the position of the first mounting hole 121 through which the pivot shaft 30 passes can be adjusted, thereby adjusting the length of the flip plate 20 extending out of the ramp 10, so that the bridging assembly 1 can adapt to the thickness of the threshold 3, thereby improving the versatility of the bridging assembly 1.

[0058] According to some embodiments of the present invention, such as Figure 3 As shown, the bridging assembly 1 also includes a support leg 40, which is disposed at the bottom of the ramp frame 10. The support leg 40 can be selectively moved relative to the ramp frame 10 to adjust the inclination angle of the support surface 11 relative to the horizontal plane. Specifically, the bottom of the ramp plate has a height-adjustable or movable support leg 40. The ramp plate is disposed on the ground and has a certain inclination angle. The support leg 40 is disposed at the bottom of the ramp plate. By adjusting or moving the support leg 40, the inclination of the ramp plate can be changed, thereby changing the height of the bridging assembly 1 so that the bridging assembly 1 can be erected on thresholds 3 of different heights. The bridging assembly 1 with the support leg 40 has an adjustable height to adapt to thresholds 3 of various sizes, making the bridging assembly 1 more versatile.

[0059] In some embodiments, when the thickness of the threshold 3 to which the bridging assembly 1 overlaps changes, the position of the first mounting hole 121 through which the pivot shaft 30 passes is first changed so that the flip plate 20 can overlap the top of the threshold 3 when in the bridging position, thereby achieving adaptive adjustment of the bridging assembly 1 to thresholds 3 of different thicknesses; when the height of the threshold 3 to which the bridging assembly 1 overlaps changes, the support leg 40 can be adjusted first to tilt the ramp plate, thereby changing the overall height of the bridging assembly 1 until the ramp plate transitions from the ground to the threshold 3 in the height direction, and then the position of the first mounting hole 121 through which the pivot shaft 30 passes is adjusted. By adjusting the support leg 40 and adjusting the position of the first mounting hole 121 through which the pivot shaft 30 passes, the bridging assembly 1 can adapt to different threshold thicknesses and / or heights.

[0060] According to some embodiments of the present invention, such as Figure 3 As shown, the bottom of the ramp frame 10 has a threaded hole, and the support leg 40 engages with the threaded hole. Rotating the support leg 40 adjusts the length of the support leg 40 extending out of the threaded hole, thereby changing the inclination angle of the ramp frame 10 relative to the horizontal plane. Specifically, the ramp plate is constructed such that it transitions from the ground to the threshold 3 in the height direction. The support surface 11 of the ramp plate is inclined in the horizontal direction. The support leg 40 is rotatably mounted on the bottom surface of the ramp plate near the threshold 3 via the threaded hole. By rotating the support leg 40, the length of the support leg 40 extending out of the threaded hole can be adjusted, thereby changing the inclination angle of the ramp plate relative to the horizontal plane, and thus adjusting the overall height of the bridging assembly 1.

[0061] In some embodiments, an anti-slip rubber pad is provided between the support leg 40 and the ground to ensure the stability of the sweeping robot when it uses the bridging component 1 to cross the threshold 3.

[0062] In some embodiments, the ramp 10 is constructed as two and is disposed on both sides of the threshold 3. Each ramp 10 is provided with a flip plate 20. The flip plates 20 extend toward each other and overlap the top of the threshold 3. The bridging assembly 1 connects the ground on both sides of the threshold 3, forming a passage from the ground on one side of the threshold 3 to the ramp 10 on that side, the flip plate 20, and then to the ramp 10 on the other side of the threshold 3 and finally to the ground on the other side of the threshold 3. This achieves the construction of a road, allowing the robot vacuum cleaner to pass smoothly through the threshold 3 and travel from the room on one side of the threshold 3 to the room on the other side of the threshold 3.

[0063] In some embodiments of the present invention, the bridging assembly 1 includes a ramp frame 10, a flip plate 20, a pivot shaft 30, and a support leg 40. The ramp frame 10 is disposed on both sides of the threshold 3, and has a support surface 11. The flip plate 20 is disposed on the support surface 11. The flip plate 20 has mating portions formed on both sides in the width direction, and second mounting holes are formed on the mating portions. The ramp frame 10 has connecting portions, and a plurality of first mounting holes 121 are arranged parallel to each other in the length direction of the connecting portions. The pivot shaft 30 can selectively engage the mating portion with one of the plurality of first mounting holes 121 to pivotally connect the ramp frame 10 and the flip plate 20. The flip plate 20 has trigger portions formed on both sides in the width direction. A threaded hole is formed at the bottom of the ramp frame 10, and the support leg 40 is rotatably disposed on the bottom surface of the ramp frame 10 near the threshold 3 through the threaded hole. The length of the support leg 40 extending beyond the threaded hole can be adjusted by rotating the support leg 40.

[0064] When installing the bridging assembly 1 onto the sill 3, it is necessary to first adjust the bridging assembly 1 to accommodate the thickness or height. Rotate the support leg 40 to tilt the ramp 10, thereby changing the overall height of the bridging assembly 1 until the ramp 10 transitions from the ground to the sill 3 in the height direction. Then, adjust the engagement position of the pivot 30 and the first mounting hole 121 so that the flip plate 20 can just overlap the top of the sill 3, thus completing the installation of the bridging assembly 1.

[0065] Door 2 and threshold 3 constitute a sliding door assembly. When the sliding door assembly is in the open state, there is no contact between door 2 and bridging assembly 1. The flip plate 20 is in the bridging position and overlaps the top of threshold 3. Bridging assembly 1 creates a path from the ground on one side of threshold 3 to the ground on the other side of threshold 3. The robot vacuum cleaner can travel from the room on one side of threshold 3 to the room on the other side of threshold 3 through bridging assembly 1. When it is necessary to close the door, the sliding door assembly switches from the open state to the closed state. Door 2 moves along threshold 3 in the first direction. At this time, the surface of door 2 in the first direction contacts the flange 21, thereby driving the flip plate 20 to flip, so that the flip plate 20 is separated from the threshold 3. When the top of the threshold 3 is opened, the road built by the bridging component 1 is disconnected, so that the door 2 can pass through and close smoothly. At this time, the flip plate 20 flips from the bridging position to the avoidance position and leans against the door 2, and the sliding door component is in the closed state. When the door needs to be opened, the sliding door component switches from the closed state to the open state, and the door 2 moves along the threshold 3 in the second direction. After the door 2 moves, the flip plate 20 leaning against the surface of the door 2 flips and resets under its own gravity and leans against the top of the threshold 3. The flip plate 20 flips from the avoidance position to the bridging position. At this time, the sliding door component is in the open state, and the bridging component 1 builds the road from the ground to the top of the threshold 3 again.

[0066] In summary, the bridging assembly 1 according to the present invention, by setting a flip plate 20, ensures that the bridging assembly 1 is in the bridging position when the sliding door assembly is open. At this time, the flip plate 20 covers the threshold 3 and does not occupy the space above the threshold 3. When the sliding door assembly is closed, the flip plate 20 moves away from the threshold 3 so that the door 2 can close normally. Such a bridging assembly 1 is convenient to use and can improve the user experience. The edge of the flip plate 20 is inclined with a flange 21, which makes it easy for the force of the door 2 to drive the flip plate 20 away from the threshold 3. The principle is simple and reliable, highly feasible, and requires little user operation, thus improving the user experience. The bridging assembly 1 has good versatility and can be used for climbing. The ramp 10 is provided with multiple first mounting holes 121. By adjusting the engagement position of the pivot shaft 30 with the first mounting holes 121, the engagement position of the flip plate 20 and the ramp 10 can be adjusted, thereby adjusting the length of the flip plate 20 extending out of the ramp 10 to adapt to the width of the threshold 3. The bottom of the ramp 10 is provided with a support leg 40. By rotating the support leg 40, the tilt angle of the ramp 10 can be adjusted to adapt to the height of the threshold 3. Such a bridging assembly 1 can adapt to thresholds 3 of various sizes. The bridging assembly 1 is also provided with a backstop part 14 to prevent the flip plate 20 from over-flipping, so that the flip plate 20 can automatically flip from the avoidance position to the bridging position.
