Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a collision avoidance plate assembly and a cleaning robot. Background Technology

[0002] Cleaning robots can replace manual labor in cleaning floors, greatly freeing people's hands and bringing convenience to family life.

[0003] In related technologies, a cleaning robot includes a main body, a movably mounted anti-collision plate on the main body, and a collision detection component located between the main body and the anti-collision plate. When the cleaning robot encounters an obstacle during operation, the anti-collision plate deforms upon collision with the obstacle, triggering the collision detection component to achieve obstacle avoidance. However, because the anti-collision plate only deforms under significant collision force with the obstacle, the triggering force for the cleaning robot is relatively large, affecting its sensitivity to obstacles. Utility Model Content

[0004] In view of this, the present invention provides a collision avoidance plate assembly and a cleaning robot to solve the problem in the related technology that the triggering force of the cleaning robot is too large, which affects the sensitivity of the cleaning robot to obstacles.

[0005] In a first aspect, this utility model provides a crash barrier assembly, comprising:

[0006] The main body of the crash barrier includes the crash barrier and a decorative strip. The decorative strip is detachably connected to the upper side of the crash barrier, and the thickness of the decorative strip is less than the thickness of the crash barrier.

[0007] The first limiting member is formed on the main body of the anti-collision plate and is used to cooperate with the second limiting member on the main body of the cleaning robot. The first limiting member is one of the limiting protrusion and the limiting groove, and the second limiting member is the other of the limiting protrusion and the limiting groove. The limiting protrusion can be disposed in the limiting groove and can move relative to the limiting groove in the front-back direction of the cleaning robot.

[0008] The first guide member is formed on the main body of the anti-collision plate. The first guide member can convert the lateral collision force received by the anti-collision plate into the movement of the anti-collision plate along the front-back direction of the robot body.

[0009] Beneficial effects: In the use of the anti-collision plate assembly of this utility model embodiment, the first limiting member can cooperate with the second limiting member to prevent the anti-collision plate assembly from moving outward or forward relative to the robot body in the initial state, and to ensure that the anti-collision plate assembly can accurately reset after colliding with an obstacle.

[0010] When the front of the cleaning robot collides with an obstacle, the anti-collision plate assembly can move backward relative to the main body of the cleaning robot and trigger the collision detection component of the cleaning robot to achieve obstacle avoidance.

[0011] When the cleaning robot collides with an obstacle on its left or right side, causing deformation of the side of the anti-collision plate, the guide can convert the left-right movement of the anti-collision plate assembly into movement toward the rear of the robot body, thereby triggering the collision detection component and thus achieving obstacle avoidance.

[0012] Because the limiting protrusion can move relative to the limiting groove along the front-back direction of the robot body, when the side wall of the anti-collision plate assembly collides with an obstacle, the anti-collision plate assembly can move flexibly relative to the robot body along the front-back direction under the action of the guide. The side wall of the anti-collision plate assembly can trigger the collision detection component without large deformation, thereby significantly reducing the triggering force of the cleaning robot to obstacles on the side and improving the sensitivity of the cleaning robot.

[0013] The thickness of the decorative strip is set to be less than that of the bumper plate, which helps to reduce the overall rigidity of the bumper plate body, thereby reducing the force required for the bumper plate assembly to deform and improving the sensitivity of the cleaning robot. In addition, the decorative strip also helps to enhance the aesthetics of the bumper plate assembly.

[0014] Therefore, the anti-collision component of this utility model can reduce the triggering force of the cleaning robot while ensuring the stability of the anti-collision plate component and preventing the anti-collision plate component from shaking, thereby improving the sensitivity of the cleaning robot to obstacles.

[0015] In addition, the above-mentioned anti-collision plate components are simple in structure, easy to assemble, safe and reliable in use, and easy to implement and promote.

[0016] In one alternative embodiment, a first limiting member is formed on the crash barrier and spaced apart along the inner circumference of the crash barrier, and the decorative strip further includes:

[0017] The main body is used for detachable connection with the crash barrier and extends from one end of the crash barrier to the other end;

[0018] A blocking edge is formed on the main body, and the blocking edge can block the first limiting member.

[0019] Beneficial effects: In this embodiment, the shielding edge is formed on the decorative strip, and the decorative strip is detachably connected to the anti-collision plate. Therefore, during the manufacturing process of the anti-collision plate assembly, the operator can demold the anti-collision plate and the decorative strip separately, avoiding the increased demolding difficulty of the anti-collision plate caused by the shielding edge and the first limiting member being set on the same structure. The anti-collision plate assembly of this embodiment can overcome the problem of difficult demolding of anti-collision plates in related technologies.

[0020] In one alternative embodiment, one of the decorative strip and the bumper plate is provided with a buckle, and the other of the decorative strip and the bumper plate is provided with a slot, the buckle being able to engage with the slot; and / or,

[0021] The decorative strip is provided with a third limiting member, and the anti-collision plate is provided with a fourth limiting member. The third limiting member is one of the limiting protrusion and the limiting groove, and the fourth limiting member is the other of the limiting protrusion and the limiting groove.

[0022] In one alternative embodiment, a guide ramp is formed on the first guide member, which is inclined inward from front to back.

[0023] Beneficial effects: When the left or right side of the cleaning robot collides with an obstacle, causing deformation of the side of the anti-collision plate body, the guide ramp can convert the left-right movement of the anti-collision plate assembly into movement towards the rear of the robot body, thereby triggering the collision detection component and achieving obstacle avoidance. In an optional embodiment, the first guide member includes a guide block disposed on the side wall of the anti-collision plate body, and the guide block is provided with a guide ramp.

[0024] In one alternative implementation, the angle between the guide ramp and the front-back direction is θ, where 40°≤θ≤60°.

[0025] Beneficial effects: When the angle between the guide ramp and the front-back direction of the cleaning robot is within the above range, the guide ramp can effectively convert the left-right movement of the anti-collision plate assembly into the front-back movement, reduce the deformation of the left and right sidewalls of the anti-collision plate assembly, and reduce the triggering force of the cleaning robot.

[0026] In one alternative implementation, the bumper assembly includes:

[0027] The fixing strip is detachably provided on the lower side of the anti-collision plate body and is detachably connected to the anti-collision plate body. The fixing strip is provided with a fifth limiting member, which is used to cooperate with the sixth limiting member on the body of the cleaning robot. The fifth limiting member is one of the limiting protrusion and the limiting groove, and the sixth limiting member is the other of the limiting protrusion and the limiting groove.

[0028] Beneficial effects: The fixing strip can cooperate with the robot body to prevent the anti-collision plate assembly from moving outward or forward relative to the robot body in the initial state, and ensure that the anti-collision plate assembly can accurately reset after colliding with an obstacle.

[0029] In one alternative embodiment, the fixing strip is provided with a first connecting hole, the anti-collision plate body is provided with a second connecting hole, and the anti-collision plate assembly further includes a fastener that passes through the first connecting hole and connects to the second connecting hole.

[0030] In one alternative implementation, the crash barrier body includes:

[0031] Front wall;

[0032] A pair of sidewalls are located at both ends of the front wall and are set at an angle to the front wall;

[0033] Connecting wall, connecting the front wall and the side wall, with a rounded transition.

[0034] Beneficial effects: This design allows the anti-collision plate assembly to be used with both square and round cleaning robots. Square and round cleaning robots can better conform to corners and clean areas that round cleaning robots cannot reach, reducing the need for manual cleaning.

[0035] However, because the anti-collision plate component of the square-round cleaning robot has a straight section on the front, when the side of the cleaning robot is subjected to force, the direction of the force is parallel to the direction of the straight section, making it difficult for the left and right sides of the anti-collision plate component to deform. Therefore, it is not easy to trigger the collision detection component, and the sensitivity of the cleaning robot is poor.

[0036] The anti-collision plate assembly of this application is connected to the robot body through a first limiting member and a second limiting member, and can move along the front-back direction of the robot body. Furthermore, the left-right movement of the anti-collision plate assembly is converted into front-back movement by a guide block, thereby ensuring the sensitivity of the sweeping robot while facilitating cleaning of areas such as corners.

[0037] Secondly, this utility model also provides a cleaning robot, comprising:

[0038] Robot body;

[0039] The anti-collision plate assembly provided in the first aspect of this utility model is located on the front side of the robot body.

[0040] Beneficial effects: The cleaning robot of the second aspect of this utility model includes or uses the anti-collision plate assembly of the first aspect of this utility model, and therefore has the beneficial effects of the anti-collision plate assembly of the first aspect of this utility model, namely: it can ensure the stability of the anti-collision plate assembly, prevent the anti-collision plate assembly from shaking, reduce the triggering force of the cleaning robot, and improve the sensitivity of the cleaning robot to obstacles.

[0041] In one alternative implementation, a second guide member is formed on the robot body, the second guide member being disposed opposite to the first guide member of the anti-collision plate assembly, and the guide ramp is formed on the second guide member.

[0042] In one alternative implementation, the cleaning robot further includes:

[0043] Shock-absorbing pads are placed between the robot body and the anti-collision plate assembly. The shock-absorbing pads are installed in pairs and are respectively placed on both sides of the robot body.

[0044] Beneficial effects: The shock-absorbing pads can be used to limit the travel of the anti-collision plate components, preventing the anti-collision plate components from colliding with the robot body and making noise, which helps to improve the user experience.

[0045] In one alternative implementation, the cleaning robot is a square-shaped sweeping machine. Attached Figure Description

[0070] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0071] In related technologies, a cleaning robot includes a main body, a collision avoidance plate movably mounted on the main body, and a collision detection component located between the main body and the collision avoidance plate.

[0072] When the cleaning robot encounters an obstacle during operation, the anti-collision plate can collide with the external obstacle and trigger the collision detection component, thereby achieving obstacle avoidance.

[0073] To prevent noise caused by the anti-collision plate swaying relative to the main body during the operation of the cleaning robot, some cleaning robots have a limiting component between the anti-collision plate assembly and the main body. This restricts the anti-collision plate to move only in the forward and backward direction relative to the cleaning robot, thereby preventing abnormal noises during use.

[0074] However, this means that when the cleaning robot collides with an obstacle on its left or right side, the anti-collision plate cannot move in the left or right direction relative to the cleaning robot. As a result, the collision detection component can only be triggered when the collision force is large and causes the anti-collision plate to deform significantly. This results in the cleaning robot having a large trigger force when encountering obstacles on its side, and its sensitivity is poor.

[0075] The following is combined with Figures 1 to 10 The following describes embodiments of the present invention.

[0076] According to an embodiment of the present invention, a crash barrier assembly 1 is provided, including a crash barrier body 101, a first limiting member 102 and a first guide member 103.

[0077] The anti-collision plate body 101 includes an anti-collision plate 1011 and a decorative strip 1012. The decorative strip 1012 is detachably connected to the upper side of the anti-collision plate 1011, and the thickness of the decorative strip 1012 is less than the thickness of the anti-collision plate 1011. A first limiting member 102 is formed on the anti-collision plate body 101 for cooperating with a second limiting member 201 on the robot body 2 of the cleaning robot. The first limiting member 102 is one of a limiting protrusion and a limiting groove, and the second limiting member 201 is the other of a limiting protrusion and a limiting groove. The limiting protrusion can be disposed in the limiting groove and can move relative to the limiting groove in the front-rear direction of the cleaning robot. A first guide member 103 is formed on the anti-collision plate body 101, and the first guide member 103 can convert the lateral collision force received by the anti-collision plate 1011 into movement of the anti-collision plate 1011 in the front-rear direction of the robot body 2.

[0078] In use, the first limiting member 102 of the anti-collision plate assembly 1 of this utility model can cooperate with the second limiting member 201 to prevent the anti-collision plate assembly 1 from moving outward or forward relative to the robot body 2 in the initial state, and to ensure that the anti-collision plate assembly 1 can accurately reset after colliding with an obstacle.

[0079] When the front of the cleaning robot collides with an obstacle, the anti-collision plate assembly 1 can move backward relative to the robot body 2 of the cleaning robot and trigger the collision detection assembly 205 of the cleaning robot to achieve obstacle avoidance.

[0080] When the left or right side of the cleaning robot collides with an obstacle, causing the side of the anti-collision plate body 101 to deform, the guide can convert the left and right movement of the anti-collision plate assembly 1 into movement toward the rear of the robot body 2, thereby triggering the collision detection assembly 205, thus achieving obstacle avoidance.

[0081] Since the limiting protrusion can move relative to the limiting groove in the front-back direction of the robot body 2, when the side wall 1016 of the anti-collision plate assembly 1 collides with an obstacle, the anti-collision plate assembly 1 can move flexibly relative to the robot body 2 in the front-back direction under the action of the guide. The side wall 1016 of the anti-collision plate assembly 1 can trigger the collision detection component 205 without undergoing large deformation, thereby significantly reducing the triggering force of the cleaning robot on the side obstacles and improving the sensitivity of the cleaning robot.

[0082] Based on this, the thickness of the decorative strip 1012 is set to be less than the thickness of the anti-collision plate 1011, which helps to reduce the overall rigidity of the anti-collision plate body 101, thereby reducing the force required for the anti-collision plate assembly 1 to deform and helping to improve the sensitivity of the cleaning robot. In addition, the decorative strip 1012 also helps to improve the aesthetics of the anti-collision plate assembly 1.

[0083] Therefore, the anti-collision component of this utility model embodiment can reduce the triggering force of the cleaning robot while ensuring the stability of the anti-collision plate component 1 and preventing the anti-collision plate component 1 from shaking, thereby improving the sensitivity of the cleaning robot to obstacles.

[0084] In addition, the above-mentioned anti-collision plate component 1 has a simple structure, is easy to assemble, and is safe and reliable to use, making it easy to implement and promote its application.

[0085] In one embodiment, the thickness of the anti-collision plate body 101 is d1, where 2.5mm≤d1≤3mm.

[0086] The thickness of the decorative part is d2, where 1.3mm ≤ d2 ≤ 2mm.

[0087] Exemplarily, in an optional embodiment, the first limiting member 102 is a limiting groove. The second limiting member 201 is a limiting protrusion. Figure 7 As shown, the second limiting member 201 can be a limiting rib.

[0088] In one embodiment, the second limiting members 201 are arranged in pairs, with each pair of second limiting members 201 symmetrically distributed along the centerline of the cleaning robot.

[0089] It should be noted that the number of second limiting members 201 is not limited in this embodiment. For example, as shown... Figure 7As shown, in an optional embodiment, there are four second limiting members 201, which are spaced apart on the anti-collision plate 1011. Preferably, the second limiting members 201 are arranged in a one-to-one correspondence with the first limiting members 102.

[0090] In related technologies, a connecting structure for connecting the robot body 2 needs to be provided on the inner circumference of the anti-collision plate 1011. To ensure aesthetics, a shielding edge 10122 needs to be provided on the inner circumference of the connecting structure to prevent the connecting structure from being exposed and compromising the aesthetics of the cleaning robot. However, when both the shielding edge 10122 and the connecting structure are provided on the inner circumference of the anti-collision plate 1011, it will be difficult to remove the mold material between the shielding edge 10122 and the connecting structure during the demolding process of the anti-collision plate 1011.

[0091] In one embodiment, a first limiting member 102 is formed on the crash barrier 1011 and is spaced apart along the inner circumference of the crash barrier 1011. For example... Figure 2 As shown, the decorative strip 1012 also includes a main body 10121 and a blocking edge 10122. The main body 10121 is detachably connected to the bumper 1011 and extends from one end of the bumper 1011 to the other. The blocking edge 10122 is formed on the main body 10121 and can block the first limiting member 102.

[0092] In this embodiment, the shielding edge 10122 is formed on the decorative strip 1012, and the decorative strip 1012 is detachably connected to the anti-collision plate 1011. Therefore, during the manufacturing process of the anti-collision plate assembly 1, the operator can demold the anti-collision plate 1011 and the decorative strip 1012 separately, avoiding the increased demolding difficulty of the anti-collision plate 1011 caused by the shielding edge 10122 and the first limiting member 102 being set on the same structure. The anti-collision plate assembly 1 of this embodiment can overcome the problem of the anti-collision plate 1011 being difficult to demold in the related art.

[0093] In one embodiment, the robot body 2 includes a base 206 and a faceplate 207, and the first limiting member 102 includes a limiting groove provided on the anti-collision plate 1011. The second limiting member 201 includes a limiting protrusion provided on the faceplate 207.

[0094] In one embodiment, such as Figure 2 As shown, one of the decorative strip 1012 and the anti-collision plate 1011 is provided with a buckle 1013, and the other of the decorative strip 1012 and the anti-collision plate 1011 is provided with a slot, and the buckle 1013 can be engaged with the slot.

[0095] With this setup, the operator can easily and quickly press the decorative strip 1012 onto the top surface of the anti-collision plate 1011 when installing the cleaning robot.

[0096] As a possible implementation, in some embodiments not shown in the accompanying drawings, the decorative strip 1012 and the anti-collision plate 1011 may also be connected to each other by a riveting assembly, a magnetic assembly or a bolt connection assembly.

[0097] The decorative strip 1012 is provided with a third limiting member 1014, and the anti-collision plate 1011 is provided with a fourth limiting member. The third limiting member 1014 is one of the limiting protrusion and the limiting groove, and the fourth limiting member is the other of the limiting protrusion and the limiting groove.

[0098] In one embodiment, the third limiting members 1014 are arranged in pairs, with each pair of third limiting members 1014 symmetrically distributed along the centerline of the decorative strip 1012.

[0099] It should be noted that, in the embodiments of this application, as Figure 5 As shown, the number of third limiting members 1014 is not limited. Exemplarily, in an optional embodiment, there are four third limiting members 1014, which are spaced apart on the decorative strip 1012. In a preferred embodiment, fourth limiting members are provided in a one-to-one correspondence with the third limiting members 1014.

[0100] In one embodiment, the crash barrier assembly 1 includes a retaining strip 104.

[0101] In one embodiment, such as Figure 4 As shown, a guide slope 1032 is formed on the first guide member 103, and the guide slope 1032 is inclined inward from front to back.

[0102] When the cleaning robot collides with an obstacle on its left or right side, causing deformation of the side of the anti-collision plate body 101, the guide ramp 1032 can convert the left-right movement of the anti-collision plate assembly 1 into movement toward the rear of the robot body 2, thereby triggering the collision detection assembly 205 and achieving obstacle avoidance. In one embodiment, such as Figure 3 As shown, the first guide member 103 includes a guide block disposed on the side wall 1016 of the anti-collision plate body 101, and the guide block is provided with a guide slope 1032.

[0103] In one embodiment, the robot body 2 is provided with a guide groove at a position corresponding to the guide block, and a guide slope 1032 is formed on one side wall of the guide groove.

[0104] In one embodiment, such as Figure 4 As shown, the angle between the guide ramp 1032 and the front-back direction is θ, where 40°≤θ≤60°.

[0105] When the angle between the guide ramp 1032 and the front-back direction of the cleaning robot is within the above range, the guide ramp 1032 can effectively convert the left-right movement of the anti-collision plate assembly 1 into the front-back movement, reduce the deformation of the left and right sidewalls 1016 of the anti-collision plate assembly 1, and reduce the triggering force of the cleaning robot.

[0106] In a preferred embodiment, the guide ramp 1032 has an angle of 45° with the front-back direction.

[0107] The fixing strip 104 is detachably disposed on the lower side of the anti-collision plate body 101 and detachably connected to the anti-collision plate body 101. The fixing strip 104 is provided with a fifth limiting member 1041, which is used to cooperate with the sixth limiting member 203 on the body of the cleaning robot (see...). Figure 8 The fifth limiting member 1041 is one of the limiting protrusion and the limiting groove, and the sixth limiting member 203 is the other of the limiting protrusion and the limiting groove.

[0108] The fixing strip 104 can cooperate with the robot body 2 to prevent the anti-collision plate assembly 1 from moving outward or forward relative to the robot body 2 in the initial state, and to ensure that the anti-collision plate assembly 1 can accurately reset after colliding with an obstacle.

[0109] In one embodiment, the robot body 2 includes a base 206 and a faceplate 207. The sixth limiting member 203 includes a limiting groove provided on the base 206. The fifth limiting member 1041 includes a limiting protrusion provided on the fixing strip 104.

[0110] It should be noted that the number of the sixth limiting member 203 is not limited in this embodiment. For example, in an optional embodiment, there are four sixth limiting members 203, spaced apart on the decorative strip 1012. In a preferred embodiment, the fifth limiting member 1041 is provided in a one-to-one correspondence with the sixth limiting member 203.

[0111] In one embodiment, such as Figure 6 As shown, the anti-collision plate 1011 also includes anti-collision rubber 1042.

[0112] The anti-collision rubber 1042 is provided on the outer periphery of the fixing strip 104.

[0113] The 1042 anti-collision rubber can act as a buffer when the cleaning robot collides with obstacles, reducing the impact force on the robot body and thus protecting it from damage.

[0114] In one embodiment, the anti-collision rubber 1042 and the fixing strip 104 are integrally injection molded.

[0115] As an alternative implementation, in some embodiments, the anti-collision rubber 1042 may also be connected to the fixing strip 104 by means of adhesive bonding or other methods.

[0116] In one embodiment, the fixing strip 104 is provided with a first connecting hole 1043, the anti-collision plate body 101 is provided with a second connecting hole 10111, and the anti-collision plate assembly 1 further includes a fastener, which passes through the first connecting hole 1043 and connects to the second connecting hole 10111.

[0117] With this configuration, the fasteners can reliably secure the fixing strip 104 to the crash barrier assembly 1.

[0118] As an alternative implementation, the fixing strip 104 may also be detachably connected to the anti-collision plate assembly 1 via a snap-fit ​​assembly or a magnetic assembly.

[0119] In one embodiment, such as Figure 3 As shown, the main body 101 of the crash barrier includes a front wall 1015, a pair of side walls 1016 and a connecting wall 1017.

[0120] A pair of sidewalls 1016 are respectively located at both ends of the front wall 1015 and are set at an angle to the front wall 1015. A connecting wall 1017 connects the front wall 1015 and the sidewalls 1016, and the connecting wall 1017 has a rounded transition.

[0121] With this design, the anti-collision plate assembly 1 can be used with both square and round cleaning robots. The square and round cleaning robots can better fit against the corners of walls and clean areas that round cleaning robots cannot reach, reducing the need for manual cleaning.

[0122] However, because the front of the anti-collision plate assembly 1 of the square-shaped cleaning robot has a straight section, when the side of the cleaning robot is subjected to force, the direction of the force is parallel to the direction of the straight section, making it difficult for the left and right sides of the anti-collision plate assembly 1 to deform. Therefore, it is not easy to trigger the collision detection component 205, and the sensitivity of the sweeping robot is poor.

[0123] The anti-collision plate assembly 1 of this application is connected to the robot body 2 via a first limiting member 102 and a second limiting member 201, and can move along the front-back direction of the robot body 2. Furthermore, the left-right movement of the anti-collision plate assembly 1 is converted into front-back movement via a guide block, thereby ensuring the sensitivity of the sweeping robot while facilitating cleaning of areas such as corners.

[0124] According to an embodiment of the present invention, another aspect provides a cleaning robot, including a robot body 2 and a collision avoidance plate assembly 1.
