Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of auxiliary equipment, in particular to an auxiliary obstacle-crossing device. BACKGROUND

[0002] In the process of cleaning a room by a sweeping robot, the sweeping robot cannot pass through the door sill of a balcony or a bathroom or other higher obstacles. By setting an auxiliary obstacle-crossing device at the door sill or other obstacles, a "bridge" can be provided for the sweeping robot to connect the ground and the door sill or other obstacles, thereby facilitating the sweeping robot to pass through. However, due to different sizes of door sills, the auxiliary obstacle-crossing device with a fixed size has a small applicable range and is highly targeted, and cannot be installed for door sills of various sizes. The universality of the auxiliary obstacle-crossing device is poor, and the user experience is poor. SUMMARY

[0003] In order to solve the above technical problems or at least partially solve the above technical problems, the present disclosure provides an auxiliary obstacle-crossing device.

[0004] The present disclosure provides an auxiliary obstacle-crossing device, comprising a climbing pad and a support arranged at the bottom of the climbing pad.

[0005] The climbing pad has an obstacle-crossing slope, which gradually rises in the direction from the side of the climbing pad away from the obstacle to the side of the climbing pad close to the obstacle.

[0006] The bottom of the climbing pad is provided with a plurality of mounting positions, and the support is switchably arranged in one of the mounting positions. When the support is arranged in different mounting positions, the inclination angle of the obstacle-crossing slope is different.

[0007] In some embodiments, when the support is arranged in at least part of the mounting positions, it can protrude from the bottom surface of the climbing pad and be supported on the placement surface on which the auxiliary obstacle-crossing device is placed.

[0008] In some embodiments, when the support is arranged in different mounting positions, the distance of protruding from the bottom surface of the climbing pad is different.

[0012] In some embodiments, the bottom of the ramp pad is provided with a plurality of support steps, each of the support steps is located at the side of the mounting positions close to the obstacle, the support steps are sequentially arranged in the direction from the side of the ramp pad away from the obstacle to the side of the ramp pad close to the obstacle, and the distance between the support steps and the bottom surface of the ramp pad gradually decreases.

[0013] In some embodiments, the support abuts against the corresponding support step as the support switches the mounting positions in sequence from the side of the ramp pad away from the obstacle to the side of the ramp pad close to the obstacle.

[0014] In some embodiments, the bottom of the ramp pad is provided with a receiving cavity recessed towards the obstacle climbing slope, the receiving cavity is located at the side of the support steps away from the obstacle; when the support is arranged at the first mounting position, the support can be located in the receiving cavity and does not protrude from the bottom surface of the ramp pad, and when the support is arranged at the remaining mounting positions, the support can abut against the corresponding support step and protrude from the bottom surface of the ramp pad.

[0016] In some embodiments, the first end of the support is provided with a mounting shaft, the mounting shaft extends along the width direction of the ramp pad.

[0017] In some embodiments, the bottom of the ramp pad is sequentially provided with a plurality of mounting grooves to form the mounting positions in the direction from the side of the ramp pad away from the obstacle to the side of the ramp pad close to the obstacle, the mounting shaft is rotatably arranged in the mounting groove, and the support can rotate around the mounting shaft to make the second end of the support abut against the support step.

[0018] In some embodiments, the second end of the support member has an abutment plane formed on one side surface facing the ramp pad, the abutment plane being adapted to abut against the support step;

[0019] The second end of the support member has a plurality of support ribs formed on the side surface facing away from the climbing pad. The plurality of support ribs are arranged sequentially at intervals along a direction parallel to the mounting axis. Each support rib has an arc-shaped support surface, which is adapted to support the placement surface.

[0020] In some embodiments, a connecting plate is connected between the plurality of supporting ribs. The connecting plate is connected to one end of the plurality of supporting ribs away from the mounting axis. The connecting plate includes an arc portion that smoothly transitions to the arc-shaped support surface of the supporting rib and a flat portion that smoothly connects to the arc portion. The flat portion is connected to the abutting plane and there is an included angle between the two. The flat portion is adapted to abut against the connecting surface connected between two adjacent supporting steps.

[0021] In some embodiments, the bottom of the climbing pad is provided with a vertical mounting rib, and the mounting rib extends along the direction from the side of the climbing pad away from the obstacle to the side of the climbing pad close to the obstacle, and a plurality of mounting grooves are sequentially spaced on the mounting rib.

[0022] The openings of the plurality of mounting grooves are all arranged facing the bottom surface of the climbing pad, and a connecting channel is formed on the side of the plurality of mounting grooves facing the bottom surface of the climbing pad, and the mounting shaft switches between the plurality of mounting grooves through the connecting channel.

[0023] In some embodiments, the mounting groove includes an arc-shaped bottom wall and a side wall connected to the bottom wall and located on the side of the bottom wall near the support step. The side wall is inclined relative to the bottom wall toward the support step. The side of the bottom wall away from the side wall extends arc-shaped toward the opening of the mounting groove to form an arc-shaped limiting surface. When the second end of the support member is supported on the support step, a portion of the outer peripheral surface of the mounting shaft abuts against the limiting surface to prevent the mounting shaft from dislodging from the mounting groove.

[0024] In some embodiments, a mounting shaft is provided at the first end of the support member, and the mounting shaft extends along the width direction of the climbing pad.

[0025] Along the direction from the side of the climbing pad away from the obstacle to the side of the climbing pad closer to the obstacle, the bottom of the climbing pad is provided with a plurality of mounting shaft holes at intervals to form a plurality of mounting positions.

[0026] In some embodiments, the bottom of the climbing pad is vertically provided with a mounting rib, and the mounting rib extends along the direction from the side of the climbing pad away from the obstacle to the side of the climbing pad close to the obstacle.

The bottom of the climbing pad has multiple mounting positions, and the support member can be switched to be disposed in one of the multiple mounting positions. When the support member is disposed in different mounting positions, the climbing pad can be raised using the support member, thereby increasing the tilt angle of the obstacle-crossing ramp.

[0046] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0047] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0048] When a robotic vacuum cleaner is cleaning a room, it may encounter obstacles such as thresholds on balconies or in bathrooms, or other high obstacles, which it may be unable to pass. Installing an obstacle-crossing device at the threshold or obstacle can create a "bridge" connecting the floor and the threshold, making it easier for the robot to pass. However, existing technologies have limitations. Fixed-size obstacle-crossing devices are only suitable for a limited range of threshold sizes and cannot be installed on thresholds of various sizes, resulting in poor versatility and a poor user experience.

[0049] Based on this, this embodiment provides an obstacle-crossing assist device that enables a mobile device (such as a robot vacuum cleaner) to smoothly cross obstacles of different heights (such as thresholds) during its movement, thus preventing the mobile device from being blocked by obstacles and unable to work.

[0050] The obstacle-crossing assist device will be described in detail below through specific embodiments:

[0051] Reference Figures 1 to 11 As shown, an embodiment of the present invention provides an obstacle-crossing auxiliary device, including a climbing pad 1 and a support member 2 disposed at the bottom of the climbing pad 1.

[0052] The climbing pad 1 has an obstacle-crossing ramp 11, which gradually increases in elevation along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle. (Refer to...) Figure 1 As shown, the relatively lower end of the obstacle-crossing ramp 11 can be set close to the ground, and the relatively higher end of the obstacle-crossing ramp 11 can abut against the obstacle. A mobile device (such as a robot vacuum cleaner) can climb up the ramp from the end away from the obstacle to the obstacle-crossing ramp, move towards the end closer to the obstacle, and gradually pass through the obstacle-crossing ramp 11 to cross the obstacle.

[0053] Specifically, refer to Figure 2 As shown, the bottom of the ramp plate 1 has multiple mounting positions, and the support member 2 can be switched to be installed in one of the multiple mounting positions. That is, the support member 2 can be installed on any of the multiple mounting positions and can be switched between multiple mounting positions. Moreover, the tilt angle of the obstacle crossing ramp 11 is different when the support member 2 is installed in different mounting positions. In other words, the tilt angle of the obstacle crossing ramp 11 can be adjusted by adjusting the installation position of the support member 2, so as to adapt to the obstacle crossing requirements of different heights, be applicable to different scenarios, and improve the user experience.

[0054] In a specific implementation, when the support member 2 is positioned at least partially at the mounting location, it protrudes from the bottom surface of the climbing pad 1 and is supported on the placement surface where the auxiliary obstacle-crossing device is placed. That is, when the support member 2 protrudes from the bottom surface of the climbing pad 1, it can support the bottom of the climbing pad 1 between the placement surface and the mounting surface, thereby raising the climbing pad 1 and increasing the tilt angle of the obstacle-crossing ramp 11 of the climbing pad 1.

[0055] Furthermore, when the support member 1 is installed in different mounting positions, the distance by which the support member 1 protrudes from the bottom surface of the climbing pad 1 is different, and the inclination of the obstacle-crossing ramp 11 changes. That is, when the distance by which the support member 1 protrudes from the bottom surface of the climbing pad 1 increases, the slope of the obstacle-crossing ramp 11 becomes steeper, and when the distance by which the support member 1 protrudes from the bottom surface of the climbing pad 1 decreases, the slope of the obstacle-crossing ramp 11 becomes gentler. Thus, by switching the mounting position of the support member 2 at the bottom of the climbing pad 1, the distance by which the support member 2 protrudes from the bottom surface of the climbing pad 1 can be adjusted, thereby adapting to obstacle-crossing requirements of different heights, applicable to different scenarios, and improving the user experience.

[0056] It should be noted that in the specific implementation, the relatively lower end of the climbing pad 1 (that is, the end of the climbing pad 1 away from the obstacle) is always set close to the ground. The support 2 is used to raise the end of the climbing pad 1 that is relatively close to the obstacle, thereby increasing the tilt angle of the obstacle-crossing slope of the climbing pad 1.

[0057] In practice, the ramp 11 gradually rises along the direction from the side of the ramp 1 away from the obstacle to the side of the ramp 1 closer to the obstacle, until it contacts the obstacle. In other words, the surface of the ramp 1 has a certain slope. At the same time, the tilt angle of the ramp 1 can change with the installation position of the support 2, so that the movable device can cross obstacles of different heights along the ramp 11.

[0058] In some embodiments, refer to Figure 2As shown, along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle—that is, along the climbing direction of the movable device—multiple mounting positions are sequentially arranged at the bottom of the climbing pad 1. When facing obstacles of different heights, the support member 2 can be switched between one of the multiple mounting positions. Simultaneously, as the support member 2 sequentially switches mounting positions along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle, the inclination angle of the obstacle-crossing ramp 11 gradually increases. That is, the inclination angle of the obstacle-crossing ramp 11 relative to the placement surface where the auxiliary obstacle-crossing device is placed gradually increases, and correspondingly, the height of the obstacle that the movable device can cross also gradually increases.

[0059] Specifically, as the support member 2 sequentially changes its installation position along the direction from the side of the climbing pad 1 furthest from the obstacle to the side of the climbing pad 1 closest to the obstacle, the distance by which the support member 2 protrudes from the bottom surface of the climbing pad 1 gradually increases, thereby making the slope of the obstacle-crossing ramp 11 gradually steeper, and the height of the obstacle that the movable device can cross also gradually increases. It can be understood that when the support member 2 protrudes from the bottom surface of the climbing pad 1, the climbing pad 1 is supported on the placement surface of the movable device by the support member 2, and the support member 2 protruding from the bottom surface of the climbing pad 1 supports the side of the climbing pad 1 closest to the obstacle. In the climbing direction of the movable device, as the support member 2 sequentially changes its installation position, the height by which the support member 2 protrudes from the bottom surface of the climbing pad 1 gradually increases. When the support member 2 is supported between the placement surface and the climbing pad 1, the slope of the obstacle-crossing ramp 11 becomes steeper, thus adapting to obstacles of different heights, suitable for different scenarios, and improving the user experience.

[0060] Furthermore, the bottom of the climbing pad 1 is provided with multiple support steps 13, all of which are located on the side of the multiple installation positions closest to the obstacle. The support member 2 can be supported on the support steps 13. It can be understood that the support member 2 protruding from the bottom surface of the climbing pad 1 is supported on the side of the climbing pad 1 closest to the obstacle, that is, the support member 2 protruding from the bottom surface of the climbing pad 1 is supported on the side of the climbing pad 1 where the support steps 13 are provided. Specifically, refer to... Figure 11 As shown, in the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle, i.e. Figure 11From left to right, multiple support steps 13 are sequentially arranged, and the distance between the multiple support steps 13 and the bottom surface of the climbing pad 1 gradually decreases, that is, the distance between the multiple support steps 13 and the placement surface of the climbing pad 1 gradually decreases. When the support member 2 is sequentially switched in installation position along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle, the support member 2 can abut against the corresponding support step 13. To ensure that the support member 2 protrudes from the bottom surface of the climbing pad 1, a support step 13 is provided on the bottom surface of the climbing pad 1. The support member 2 is placed against the support step 13. When the support member 2 is placed against different support steps 13, the support member 2 protrudes from the bottom surface of the climbing pad 1 at different heights. Furthermore, as the support member 2 is installed in different positions along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle, the distance by which the support member 2 protrudes from the bottom surface of the climbing pad 1 gradually increases. As a result, the inclination angle of the obstacle-crossing ramp 11 of the climbing pad 1 gradually becomes steeper when the support member 2 is installed in different positions.

[0061] Of course, it should be understood that in specific implementations, when the support member 1 is installed in different mounting positions, the distance by which the support member 1 protrudes from the bottom surface of the ramp pad 1 can also be the same. For example, multiple mounting positions are sequentially arranged at the bottom of the ramp pad 1 along the direction from the side of the ramp pad 1 closest to the obstacle to the side of the ramp pad 1 furthest from the obstacle; when the support member 2 sequentially switches mounting positions along the direction from the side of the ramp pad 1 closest to the obstacle to the side of the ramp pad 1 furthest from the obstacle, the distance by which the support member 2 protrudes from the bottom surface of the ramp pad 1 is the same. Since the support member 2 gradually moves towards the side furthest from the obstacle when switching mounting positions, that is, the distance from the end of the ramp pad 1 furthest from the obstacle becomes smaller and smaller, and the end of the ramp pad 1 furthest from the obstacle is supported on the placement surface, the closer movement of the support member 2 causes an increase in the tilt angle of the obstacle-crossing ramp 11 even if the distance by which the support member 2 protrudes from the bottom surface of the ramp pad 1 does not change, thereby achieving the purpose of adjusting the tilt angle of the obstacle-crossing ramp 11.

[0062] In some embodiments, refer to Figure 2 As shown, the bottom of the climbing pad 1 is provided with a recessed cavity forming a slope 11 for overcoming obstacles. The cavity is located on the side of the multiple supporting steps 13 away from the obstacle. Along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle, when the support member 2 is installed in the first mounting position (i.e., the leftmost mounting position), the support member 2 can be located within the cavity and does not extend beyond the bottom surface of the climbing pad 1. This auxiliary obstacle-crossing device is supported on the placement surface by the climbing pad 1. In other words, referring to… Figure 5As shown, when the support member 2 is located in the accommodating cavity, the support member 2 will not affect the tilt angle of the obstacle-crossing ramp 11 of the climbing pad 1, so that the obstacle-crossing ramp 11 has an initial tilt angle; refer to Figure 6 and Figure 7 As shown, when the support member 2 is installed in other installation positions, the support member 2 can abut against the corresponding support step 13 and protrude from the bottom surface of the climbing pad 1, and can be supported on the support surface.

[0063] For example, refer to Figure 11 As shown, the bottom of the ramp pad 1 has five mounting positions for installing the support member 2, and correspondingly, there are four support steps 13. It can be understood that when the support member 2 is installed in the leftmost mounting position, the support member 2 can be located in the receiving cavity formed at the bottom of the ramp pad 1, and when the support member 2 is installed in the other four mounting positions, the support member 2 can abut against the step surface 131 of the four support steps 13.

[0064] It should be noted that, in specific implementations, to facilitate switching of the mounting positions of the support member 2, the mounting state of the support member 2 in each mounting position is not limited to fixed, but can also be movable. For example, the support member 2 can be rotatably mounted in the mounting position. When it is not necessary to change the tilt angle of the obstacle-crossing ramp 11, the support member 2 can be mounted in the first mounting position, i.e. Figure 2 The leftmost installation position is used to house the support member 2 within the cavity formed at the bottom of the ramp pad 1, ensuring that the support member 2 does not protrude beyond the bottom surface of the ramp pad 1. When it is necessary to adjust the tilt angle of the obstacle-crossing ramp 11, the support member 2 can be rotated to move it out of the cavity. Then, the support member 2 can be moved and switched to the installation position located to the right of the first installation position. The support member 2 can then be rotated to support itself on the corresponding support step 13, causing it to protrude beyond the bottom surface of the ramp pad 1 and be supported on the placement surface, thereby achieving the purpose of increasing the tilt angle of the obstacle-crossing ramp 11.

[0065] In some embodiments, refer to Figure 3As shown, the support member 2 has a first end and a second end that are arranged opposite to each other. Specifically, the support member 2 can be integrally plate-shaped, with the two opposite ends of the plate-shaped structure forming the first end and the second end, respectively. Multiple reinforcing ribs can be provided on the side surface of the plate-shaped structure facing away from the ramp pad 1, and the multiple reinforcing ribs are connected between the first end and the second end. The first end of the support member 2 can be switched to one of the multiple mounting positions, thereby changing the slope of the obstacle-crossing ramp 11 to adapt to obstacles of different heights. When the first end of the support member 2 is located in one of the multiple mounting positions, it can abut against the corresponding support step 13 or against the bottom surface of the receiving cavity formed at the bottom of the ramp pad 1. When the second end of the support member 2 abuts against the support step 13, the second end can protrude from the bottom surface of the ramp pad 1 and be supported on the placement surface on which the auxiliary obstacle-crossing device is placed.

[0066] It should be noted that, in the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 close to the obstacle, as the support member 2 switches the installation position in sequence, the distance by which the second end protrudes from the bottom surface of the climbing pad 1 gradually increases. When the second end is supported on the placement surface, it can match obstacles of different heights, so that the movable device can pass through the obstacle-crossing ramp 11.

[0067] Specifically, the first end of the support member 2 is provided with a mounting shaft 22, which extends along the width direction of the climbing pad 1. For example... Figure 2 The double-headed arrows indicate the width direction of the ramp pad 1. Specifically, the mounting shaft 22 is rotatably mounted in different mounting positions, which facilitates the removal of the support member 2 from the receiving cavity. After switching between different mounting positions, the support member 2 can fit against the support step 13.

[0068] Specifically, along the direction from the side of the ramp pad 1 away from the obstacle to the side of the ramp pad 1 closer to the obstacle, a plurality of mounting grooves 121 are sequentially provided on the bottom of the ramp pad 1 to form a plurality of mounting positions, so that the support member 2 can switch mounting positions along the direction from the side of the ramp pad 1 away from the obstacle to the side of the ramp pad 1 closer to the obstacle. Specifically, the mounting shaft 22 is rotatably disposed in different mounting grooves 121, and the support member 2 can rotate about the mounting shaft 22 as an axis so that the second end of the support member 2 abuts against the support step 13, thereby allowing the slope of the ramp pad 1 to change as the support member 2 rotates.

[0069] Reference Figure 9 and Figure 11As shown, the second end of the support member 2 has an abutment plane 21 formed on the side facing the ramp pad 1. The abutment plane 21 is adapted to abut against the support step 13. It can be understood that, in order for the support member 2 to have high support performance, the step surface 131 of the support step 13 is adapted to the inclination design of the support member 2, allowing the support member 2 to abut against the step surface 131 of the support step 13, achieving surface-to-surface contact. Specifically, the plane on the support member 2 that abuts against the step surface 131 of the support step 13 is formed as the abutment plane 21. When the support member 2 is located... Figure 11 When the support member 2 is in the leftmost mounting groove 121, the abutting plane 21 abuts against the bottom surface of the receiving cavity formed at the bottom of the climbing pad 1. Figure 11 When the other mounting grooves 121 are in the mounting grooves, the abutting plane 21 abuts against the step surface 131 of the supporting step 13, and all of them are in surface-to-surface contact.

[0070] Specifically, refer to Figure 3 As shown, the second end of the support member 2 has multiple supporting ribs 24 formed on the side facing away from the ramp pad 1. These supporting ribs 24 are spaced apart sequentially along a direction parallel to the mounting shaft 22. Each supporting rib 24 has an arc-shaped supporting surface 241, which is suitable for support on the placement surface. When the mounting shaft 22 is positioned in different mounting grooves 121, the contact point between the second end of the support member 2 and the placement surface changes. The arc-shaped supporting surface 241 allows the support member 2 to be stably supported on the placement surface. In a specific implementation, the multiple supporting ribs 24 can be an integral structure formed on the support member 2.

[0071] In some embodiments, refer to Figure 3 As shown, connecting ribs 23 connect multiple supporting ribs 24. The connecting ribs 23 are connected to the ends of the multiple supporting ribs 24 away from the mounting shaft 22. The connecting ribs 23 are fixedly mounted on the multiple supporting ribs 24. The connecting ribs 23 and the supporting ribs 24 together form the second end of the support member 2. The second end is arc-shaped, ensuring that the arc-shaped support surface 241 is always in contact with the placement surface when the second end is supported on the placement surface. Specifically, refer to... Figure 9As shown, the connecting rib 23 includes an arcuate portion 232 that smoothly transitions to the arcuate support surface 241 of the supporting rib 24, and a flat portion 231 that smoothly connects to the arcuate portion 232. The flat portion 231 is connected to the abutting surface 21 and the two have an included angle. The flat portion 231 is adapted to abut against the connecting surface 132 connecting two adjacent supporting steps 13. Of course, it should be noted that the included angle between the flat portion 231 and the abutting surface 21 is equal to the included angle between the step surface 131 and the connecting surface 132 of the supporting step 13. When the support member 2 switches between different mounting grooves 121, the abutting surface 21 can always contact the step surface 131, and the flat portion 231 can always contact the connecting surface 132. That is to say, the support member 2 is limited between the connecting surface 132, the placement surface, and the mounting groove 121.

[0072] It is understandable that, in order to ensure that the flat part 231 is always in contact with the connecting surface 132, the connecting surface 132 located between the step surfaces 131 also has a certain tilt angle. The size of the tilt angle depends on the size of the climbing pad 1 and the support member 2, as well as the height at which the climbing pad 1 changes. This disclosure does not limit this, as long as the flat part 231 is always in contact with the connecting surface 132, ensuring the stability of the support, and enabling the movable device to smoothly cross obstacles of various heights.

[0073] In some embodiments, refer to Figures 2 to 4 As shown, a mounting rib 12 is vertically arranged at the bottom of the climbing pad 1, and the mounting rib 12 extends along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle. Multiple mounting grooves 121 are arranged sequentially and at intervals on the mounting rib 12. It can be understood that one mounting shaft 22 corresponds to one pair of mounting ribs 12, that is, two mounting ribs 12. The mounting shaft 22 is rotatably mounted on the mounting rib 12. Mounting grooves 121 are provided at different positions on the mounting rib 12, and the mounting grooves 121 are arranged on the mounting rib 12 along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle, so that the support member 2 can switch the installation position along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle. Of course, it should be noted that the number of mounting ribs 12 can also be 3, 4 or more, as long as the mounting shaft 22 can be fixed to the bottom of the climbing pad 1 and the mounting shaft 22 can rotate. This disclosure does not limit this.

[0074] Specifically, refer to Figure 3As shown, the openings of multiple mounting grooves 121 are all oriented towards the bottom surface of the ramp pad 1, and a connecting channel 122 is formed on the side of the mounting grooves 121 facing the bottom surface of the ramp pad 1. The connecting channel 122 connects the multiple mounting grooves 121, and the mounting shaft 22 switches between the multiple mounting grooves 121 through the connecting channel 122. Specifically, the width of the connecting channel 122 and the width of the opening of the mounting groove 121 are slightly larger than the diameter of the mounting shaft 22, so that the mounting shaft 22 can switch to different mounting grooves 121 through the connecting channel 122 to adjust the height of the ramp pad 1. Of course, it should be noted that the openings of the multiple mounting grooves 121 can also be oriented towards the bottom of the ramp pad 1, with the connecting channel 122 located on the side of the mounting grooves 121 facing the bottom of the ramp pad 1. As long as the support member 2 can switch between the multiple mounting grooves 121, the height of the ramp pad 1 can be adjusted and it can be used for obstacles of different heights.

[0075] In some embodiments, refer to Figure 9 and Figure 11As shown, the mounting groove 121 includes an arc-shaped bottom wall 1211 and a side wall 1212 connected to the bottom wall 1211 and located on the side of the bottom wall 1211 near the support step 13. The mounting shaft 22 abuts against the arc-shaped bottom wall 1211. The side wall 1212 is located on the side of the bottom wall 1211 near the support step 13 and is tangential to the bottom wall 1211. The side wall 1212 is inclined relative to the bottom wall 1211 toward the support step 13. Understandably, the inclined design of the groove sidewall 1212 can widen the groove opening, making it easier for the mounting shaft 22 to be removed from the mounting groove 121, and also facilitating the sliding of the mounting shaft 22 into the mounting groove 121, thus enabling the support member 2 to change its position at the bottom of the climbing pad 1. Simultaneously, the side of the groove bottom wall 1211 away from the groove sidewall 1212 extends in an arc towards the groove opening of the mounting groove 121, forming an arc-shaped limiting surface 1213. The limiting surface 1213 forms a semi-enclosed structure, surrounding at least part of the mounting shaft 22. When the second end of the support member 2 is supported on the support step 13, the first end is located in the mounting groove 121 and supports and abuts against the bottom wall 1211 of the mounting groove 121. That is, the mounting shaft 22 is supported and abuts against the bottom wall 1211 of the groove. Part of the outer peripheral surface of the mounting shaft 22 abuts and cooperates with the limiting surface 1213. The limiting surface 1213 applies a certain limiting effect to the mounting shaft 22, so that the mounting shaft 22 is limited in the mounting groove 121 to prevent the mounting shaft 22 from coming out of the mounting groove 121. It should be noted that the width of the groove opening of the mounting groove 121 can also be slightly smaller than the diameter of the mounting shaft 22. By limiting the size of the groove opening of the mounting groove 121, the mounting shaft 22 is prevented from coming out of the mounting groove 121. This disclosure does not limit this, as long as the support member 2 can be limited in the mounting groove 121. Specifically, when the groove opening of the mounting groove 121 is set facing the bottom of the climbing pad 1, the mounting shaft 22 can completely abut against the bottom wall 1211 of the mounting groove 121, and the support member 2 will not come out. As long as the corresponding tilt angle and size are set so that the support member 2 can abut against the support step 13, the movable device can pass through.

[0076] In other embodiments, the first end of the support member 2 is provided with a mounting shaft 22, which extends along the width direction of the ramp pad 1. Along the direction from the side of the ramp pad 1 away from the obstacle to the side of the ramp pad 1 near the obstacle, the bottom of the ramp pad 1 is provided with a plurality of mounting shaft holes spaced apart to form a plurality of mounting positions, allowing the support member 2 to switch mounting positions along the direction from the side of the ramp pad 1 away from the obstacle to the side of the ramp pad 1 near the obstacle. Specifically, the mounting shaft 22 is rotatably disposed in different mounting shaft holes, and the mounting shaft 22 is detachably connected to the mounting shaft holes. When the mounting shaft 22 is detachably installed in different mounting shaft holes, the support member 2 can protrude from the bottom surface of the ramp pad 1 by different distances. Specifically, as the support member 2 sequentially switches mounting positions along the direction from the side of the ramp pad 1 away from the obstacle to the side of the ramp pad 1 near the obstacle, the distance by which the support member 2 protrudes from the bottom surface of the ramp pad 1 gradually increases.

[0077] In some embodiments, a mounting rib 12 is vertically provided at the bottom of the climbing pad 1, and the mounting rib 12 extends along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle. Multiple mounting shaft holes are sequentially spaced on the mounting rib 12. It can be understood that one mounting shaft 22 corresponds to a pair of mounting ribs 12, i.e., two mounting ribs 12. The mounting shaft 22 is rotatably mounted on the mounting rib 12. Mounting shaft holes are provided at different positions on the mounting rib 12, and these mounting shaft holes are arranged along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle, allowing the support member 2 to switch its mounting position along the direction from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle. Of course, it should be noted that the number of mounting ribs 12 can also be three, four, or more, as long as the mounting shaft 22 can be fixed to the bottom of the climbing pad 1 and the mounting shaft 22 can rotate. This disclosure does not limit this.

[0078] In practice, a deformation force is applied to the mounting shaft 22 or the mounting stiffener 12 to disengage the mounting shaft 22 from the mounting shaft 22 hole. It is understood that by applying a deformation force to the mounting shaft 22 or the mounting stiffener 12 to detachably connect the mounting shaft 22 to the mounting shaft hole, the mounting shaft 22 can be switched between different positions in the mounting shaft hole. It should be noted that the "detachable" connection method is not limited to applying a deformation force to the mounting shaft 22 or the mounting stiffener 12; other means, such as snap-fit, can also be used to detachably mount the mounting shaft 22 onto the ramp pad 1, as long as it facilitates changing the mounting position of the support member 2 and adjusting the height of the ramp pad 1. This disclosure does not limit this.

[0079] In some embodiments, the second end of the support member 2 has a protruding buckle 25 on the side facing the ramp pad 1, and the support step 13 has a corresponding locking hole 15, in which the buckle 25 is detachably engaged. Specifically, refer to Figure 10 and Figure 11 As shown, a protruding buckle 25 is provided on the contact plane 21 where the support member 2 abuts against the step surface 131. A corresponding locking hole 15 is provided on the step surface 131 of the supporting step 13 at a corresponding position. By engaging the buckle 25, the support member 2 can be fixed in the current installation position. It can be understood that when it is necessary to adjust the installation position of the support member 2, the ramp pad 1 needs to be lifted from the placement surface, the mounting shaft 22 is placed in the installation groove 121 to be adjusted, and the bottom surface of the ramp pad 1 is placed facing the placement surface. Engaging the buckle 25 prevents the support member 2 from coming out of the installation groove 121 during placement. Specifically, under the combined action of the buckle 25 and the limiting surface 1213, the support member 2 is limited to the current position.

[0080] Of course, it should be noted that in Figure 8 and Figure 10 In the illustrated embodiment, the bottom of the ramp pad 1 is provided with five mounting positions. The abutment plane 21 can abut against the bottom of the support pad or the step surface 131. That is, the bottom of the support pad and the four step surfaces 131 are provided with locking holes 15. When the support member 2 is located in different mounting positions, the buckles 25 on the support member 2 can be fixedly engaged in the locking holes 15 at different positions to prevent the support member 2 from falling out. The shape, size, position and number of the buckles 25 and the locking holes 15 only need to correspond one-to-one, as long as the support member 2 can be fixed. This disclosure does not limit this.

[0081] In some embodiments, refer to Figure 3 and Figure 4As shown, there are two support members 2, which are sequentially arranged at the bottom of the climbing pad 1 along its width. Correspondingly, there are four mounting ribs 12, which are arranged at the bottom of the climbing pad 1 along its width. Each mounting rib 12 has multiple mounting grooves 121, which are arranged from the side of the climbing pad 1 away from the obstacle to the side of the climbing pad 1 closer to the obstacle. The mounting grooves 121 on the four mounting ribs 12 are positioned correspondingly to each other. When two support members 2 are placed in any mounting groove 121, the two support members 2 protrude from the bottom surface of the climbing pad 1 at the same height, jointly supporting the climbing pad 1 and changing the height of the climbing pad 1. Of course, it should be noted that the number of support members 2 can also be three, four, or more, as long as the support members 2 can be reasonably arranged at the bottom of the climbing pad 1 and the height of the support members 2 protruding from the bottom surface of the climbing pad 1 can be guaranteed to be the same. This disclosure does not limit this.

[0082] In some embodiments, refer to Figure 1 As shown, a recessed platform is provided on the side of the obstacle-crossing slope 11 of the climbing pad 1 near the placement surface. A QR code can be placed on the vertical surface of the recessed platform. The position and height of the QR code are consistent with the scanning and recognition height of the sweeping robot, so that the robot can make a climbing command when it reaches the designated area of ​​the obstacle to pass through the obstacle.

[0083] Continue to refer to Figure 1 As shown, an anti-slip structure is provided on the obstacle-crossing ramp 11 of the climbing pad 1. By providing an anti-slip structure on the obstacle-crossing ramp 11, the movable device can be prevented from sliding or slipping on the ramp 11 to a certain extent. Specifically, the anti-slip structure can be, for example, anti-slip stripes, etc. For instance, there can be multiple anti-slip stripes, which are spaced apart along the climbing direction of the movable device. Of course, the anti-slip structure can also be spaced anti-slip protrusions. The anti-slip structure can be integrally formed with the climbing pad 1. Specifically, the anti-slip structure can have a certain degree of elasticity.
