Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a collision reset structure and a sweeper. Background Technology

[0002] In recent years, with the development of technology, cleaning robots have become increasingly intelligent, capable of cleaning within designated areas and greatly freeing up people's hands. To prevent robot vacuums from colliding with obstacles in blind spots that intelligent obstacle avoidance sensors cannot detect, they are typically equipped with anti-collision plates at the front for mechanical obstacle avoidance. When the anti-collision plate is struck by an obstacle, it triggers a collision linkage on its back, generating an electrical signal, which is then reset to its initial position by a reset mechanism. However, existing reset mechanisms sometimes fail to reset completely or are not centered properly, affecting the sensitivity of mechanical obstacle avoidance. Utility Model Content

[0003] Therefore, it is necessary to provide a collision reset structure and a sweeping machine to address the problem that existing reset structures may fail to reset properly or be misaligned during actual use, thus affecting the sensitivity of mechanical obstacle avoidance.

[0004] The technical solution is as follows:

[0005] Firstly, a collision reset structure is provided, comprising:

[0006] A movable main body has a mounting part on its front side, and a first limiting part is provided on the mounting part;

[0007] The anti-collision plate is movable in multiple directions and installed on the front side of the moving body;

[0008] A first elastic element is located between the moving body and the anti-collision plate, and includes a sleeve portion, a second limiting portion and an elastic abutment portion disposed on the sleeve portion. The sleeve portion is sleeved on the mounting portion and is limited to cooperate with the mounting portion in an assembly direction perpendicular to the sleeve portion. The second limiting portion is configured to cooperate with the first limiting portion in the assembly direction when the sleeve portion is sleeved on the mounting portion. The elastic abutment portion abuts against the anti-collision plate.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, the number of the first limiting part and the number of the second limiting part are both at least one, and each of the second limiting parts is arranged at intervals along the circumference of the sleeve part and is correspondingly limited and cooperated with each of the first limiting parts.

[0011] In one embodiment, the first limiting part is configured as a limiting slot and is disposed on the outer side wall of the mounting part, and the second limiting part is configured as a limiting buckle. The limiting buckle is disposed at the end of the sleeve part away from the moving body and is at least partially located inside the sleeve part. The limiting buckle is configured to extend into the limiting slot when the sleeve part is fitted onto the mounting part and to engage with the inner side wall of the limiting buckle for limiting.

[0012] In one embodiment, the collision reset structure further includes a collision detection component, which is installed on the front side of the moving body and configured to correspond to the inner wall of the anti-collision plate when the anti-collision plate is in the initial state and there is no interaction force between them, and to abut against the inner wall of the anti-collision plate and generate a collision signal when the anti-collision plate is in a collision state.

[0013] In one embodiment, the collision detection component is configured to have a gap between itself and the inner wall of the crash barrier when the crash barrier is in its initial state, the gap being in the range of 0 mm to 2 mm.

[0014] In one embodiment, the front side of the moving body is provided with a mounting cavity, the mounting cavity having an opening extending to the front wall of the moving body. The collision detection component includes a collision linkage, a second elastic element and an optocoupler switch mounted in the mounting cavity. The second elastic element is connected to the collision linkage. The collision linkage includes a rotating shaft and a first end and a second end disposed on opposite sides of the rotating shaft. The rotating shaft is rotatably mounted in the mounting cavity. The first end passes through the opening and is disposed corresponding to the inner wall of the anti-collision plate. The second end is configured to extend into the optocoupler switch to block the light path when the anti-collision plate is in an initial state, and to move out of the optocoupler switch when the anti-collision plate is in a collision state, so that the light path of the optocoupler switch is opened and a collision signal is generated.

[0015] In one embodiment, when the crash barrier contacts the first end, the first end contacts the crash barrier perpendicularly in the horizontal direction.

[0016] In one embodiment, the collision detection assembly further includes a sealing ring, which is fitted onto the first end and seals the inner wall of the mounting cavity with the outer wall of the first end.

[0017] Secondly, a collision reset structure is provided, including:

[0018] Moving subject;

[0019] A crash barrier is movably installed on the front side of the moving body in multiple directions. The inner wall of the crash barrier is provided with a mounting part, and the mounting part is provided with a first limiting part.

[0020] A first elastic element is located between the moving body and the anti-collision plate, and includes a sleeve portion, a second limiting portion and an elastic abutment portion disposed on the sleeve portion. The sleeve portion is sleeved on the mounting portion and is limited to cooperate with the mounting portion in an assembly direction perpendicular to the sleeve portion. The second limiting portion is configured to cooperate with the first limiting portion in the assembly direction when the sleeve portion is sleeved on the mounting portion. The elastic abutment portion abuts against the moving body.

[0021] Thirdly, a sweeping machine is provided, including the aforementioned collision reset structure.

[0022] In the above embodiments, the collision reset structure and sweeper, during use, have an elastic abutment part that abuts against the inner wall of the anti-collision plate to apply a pre-tightening force to the anti-collision plate. This ensures that the anti-collision plate will not shake or make noise during the normal movement of the moving body. Simultaneously, it provides a reset force to the anti-collision plate when it is in a collision state, and reduces the amplitude of vibration under the pre-tightening force after the anti-collision plate resets, thereby reducing noise. This ensures that the anti-collision plate can accurately and reliably reset to its initial state, improving the reliability of the collision reset structure. Furthermore, this application uses a sleeve-type connection to mount the mounting part. Simultaneously, the first limiting part and the second limiting part also correspondingly limit and cooperate, achieving stable and reliable fixing of the first elastic element to the front side of the moving body. This simple and convenient operation improves the assembly convenience of the collision reset structure. Attached Figure Description

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] like Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, a collision reset structure 10 is provided, including a movable body 100, a crash barrier 200, and a first elastic member 300. The movable body 100 has a mounting portion 110 on its front side, and a first limiting portion 120 is provided on the mounting portion 110. The crash barrier 200 is movably mounted on the front side of the movable body 100. The first elastic member 300 is located between the movable body 100 and the crash barrier 200, and includes a sleeve portion 310, a second limiting portion 320 provided on the sleeve portion 310, and an elastic abutment portion 330. The sleeve portion 310 is sleeved on the mounting portion 110 and is limited in engagement with the mounting portion 110 along an assembly direction perpendicular to the sleeve portion 310. The second limiting portion 320 is configured to limit the engagement with the first limiting portion 120 along the assembly direction when the sleeve portion 310 is sleeved on the mounting portion 110. The elastic abutment portion 330 abuts against the crash barrier 200.

[0034] In the above embodiment, the collision reset structure 10, when in use, the elastic abutment part 330 abuts against the inner wall of the anti-collision plate 200 to apply a pre-tightening force to the anti-collision plate 200, ensuring that the anti-collision plate 200 will not shake and make noise during the normal movement of the moving body 100. At the same time, it can also provide a reset force to the anti-collision plate 200 when it is in a collision state, and reduce the amplitude of vibration under the action of the pre-tightening force after the anti-collision plate 200 is reset, thereby reducing noise. This ensures that the anti-collision plate 200 can be accurately and reliably reset to the initial state, improving the reliability of the collision reset structure 10. In addition, this application uses a sleeve to fit the sleeve part 310 onto the mounting part 110. At the same time as the sleeve part 310 is fitted onto the mounting part 110, the first limiting part 120 and the second limiting part 320 also cooperate to limit and match, so that the first elastic member 300 is stably and reliably fixed to the front side of the moving body 100. The operation is simple and convenient, improving the assembly convenience of the collision reset structure 10.

[0035] The mounting part 110 can be configured as a mounting rib, mounting base, mounting block, or other mounting structure. The mounting part 110 can be oriented upwards or downwards. The assembly direction of the socket part 310 refers to the direction in which the socket part 310 is installed and removed. Specifically, in this embodiment, the assembly direction of the socket part 310 can be set to the up-down direction (e.g., vertical direction). Figure 2 (The direction indicated by A in the diagram). The mounting part 110 is positioned upwards, and the socket part 310 is assembled onto the mounting part 110 from top to bottom. The assembly direction perpendicular to the socket part 310 refers to the direction perpendicular to A. Specifically, when the direction indicated by A is up and down, the assembly direction perpendicular to the socket part 310 is horizontal. In other embodiments, the assembly direction of the socket part 310 can also be set as an inclined direction, a left and right direction, or a front and back direction, etc.

[0036] The anti-collision plate 200 can be installed on the front side of the mobile body 100 using any of the existing technologies that allows for multi-directional movability. "The anti-collision plate 200 can be movably installed on the front side of the mobile body 100 in multiple directions" means that the anti-collision plate 200 and the front side of the mobile body 100 are connected in the front-rear direction (e.g., along the longitudinal direction). Figure 1 In addition to moving and cooperating in the direction shown in B, it can also move and cooperate with the front side of the moving body 100 in the up-down direction, move and cooperate with the front side of the moving body 100 in the left-right direction, or move and cooperate with the front side of the moving body 100 in both the up-down and left-right directions.

[0037] The socket portion 310, the second limiting portion 320, and the elastic abutment portion 330 can be integrally formed; for example, the first elastic element 300 can be a spring sheet. The socket portion 310 can be configured as a closed annular structure or as a non-closed annular structure. Specifically, in this embodiment, the socket portion 310 includes a socket body and two fixing hooks respectively disposed on the left and right sides of the socket body. Along the assembly direction of the socket portion 310, the projected area of ​​the socket portion 310 is C-shaped.

[0038] The second limiting part 320 can be configured as a limiting hook, a limiting protrusion, or other limiting structure. The first limiting part 120 can be configured as a limiting rib, a limiting groove, or other limiting structure. The number of first limiting parts 120 and the number of second limiting parts 320 can be flexibly adjusted according to actual usage needs. The elastic abutment part 330 includes an elastic arm, one end of which is connected to the sleeve part 310, and the other end protrudes from the moving body 100 and abuts against the anti-collision plate 200.

[0039] like Figure 3 As shown, optionally, the number of first limiting portions 120 and second limiting portions 320 is at least one. Each second limiting portion 320 is arranged at intervals along the circumference of the sleeve portion 310 and corresponds to and limits the engagement with each first limiting portion 120. In this way, by increasing the number of first limiting portions 120 and second limiting portions 320, the number of limiting surfaces and the limiting area between the first elastic member 300 and the mounting portion 110 are increased, ensuring that the first elastic member 300 will not detach from the mounting portion 110, and improving the reliability of the collision reset structure 10.

[0040] like Figure 1 and Figure 3As shown, in one embodiment, the first limiting part 120 is configured as a limiting groove 121 and is disposed on the outer side wall of the mounting part 110. The second limiting part 320 is configured as a limiting buckle 321, which is disposed at the end of the sleeve part 310 away from the moving body 100 and is at least partially located inside the sleeve part 310. The limiting buckle 321 is configured to extend into the limiting groove 121 when the sleeve part 310 is fitted onto the mounting part 110 and to engage with the inner side wall of the limiting buckle 321. In this way, while the sleeve part 310 is fitted onto the mounting part 110, the limiting buckle 321 also engages with the limiting groove 121, improving the assembly convenience of the collision reset structure 10.

[0041] Wherein, the limiting buckle 321 being at least partially located inside the socket 310 means that, along the assembly direction of the socket 310, the projection area of ​​the limiting buckle 321 is at least partially located inside the projection area of ​​the socket 310.

[0042] like Figure 1 and Figure 3 As shown, optionally, the end of the sleeve portion 310 away from the limiting buckle 321 is configured to engage with the moving body 100 when the sleeve portion 310 is fitted onto the mounting portion 110. In this way, the moving body 100 can engage with the inner wall of the limiting groove 121 on the side away from the moving body 100 to fix the first elastic member 300 onto the mounting portion 110, improving the reliability of the collision reset structure 10.

[0043] like Figure 2 and Figure 3 As shown, in one embodiment, the number of mounting portions 110 and first elastic members 300 is at least two. Each mounting portion 110 is positioned along the left-right direction (e.g., ...). Figure 2 The first elastic elements 300 are spaced apart in the direction shown in C) on the front side of the moving body 100 and are correspondingly arranged with each of the first elastic elements 300. In this way, the first elastic elements 300 are spaced apart in the left and right direction to ensure that the preload force on the anti-collision plate 200 is evenly distributed, thereby ensuring that the anti-collision plate 200 can be accurately and reliably reset to the initial state after the collision reset, and improving the reliability of the collision reset structure 10.

[0044] The number of mounting parts 110 and the number of first elastic elements 300 can be flexibly adjusted according to actual usage needs.

[0045] like Figure 2 As shown, optionally, there are two mounting portions 110 and two first elastic members 300. The mounting portions 110 are symmetrically arranged on the front side of the movable body. The two first elastic members 300 are correspondingly arranged with the two mounting portions 110 and are symmetrically fixed to the front side of the movable body 100.

[0046] like Figure 1 As shown, optionally, the movable body 100 includes a base 140 and a faceplate 150 mounted on the base 140. The mounting portion 110 may be disposed on the base 140 and / or the faceplate 150. Specifically, in this embodiment, two first elastic members 300 are symmetrically fixed to the front side of the faceplate 150. In other embodiments, the two first elastic members 300 may also be symmetrically fixed to the front side of the base 140, or symmetrically fixed to the front side of the connection point between the faceplate 150 and the base 140.

[0047] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, the collision reset structure 10 further includes a collision detection component 400. The collision detection component 400 is mounted on the front side of the moving body 100 and is configured to correspond to the inner wall of the anti-collision plate 200 when the anti-collision plate 200 is in the initial state and there is no interaction force between the two, and to abut against the inner wall of the anti-collision plate 200 and generate a collision signal when the anti-collision plate 200 is in a collision state.

[0048] The collision detection component 400 can be configured as any existing structure capable of converting a collision condition into a collision signal (e.g., an electrical signal). The number and installation position of the collision detection components 400 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, there are two collision detection components 400, which are symmetrically arranged on the front side of the moving body 100. In this way, the anti-collision plate 200 maintains a distance from or only contacts the two collision detection components 400 in the initial state, preventing the detection components on the other side from being triggered due to the overall rotation of the anti-collision plate 200 after a collision from one side, reducing the possibility of false triggering of the collision detection components 400, and improving the reliability of the collision reset structure 10.

[0049] Optionally, the collision detection component 400 is configured to have a gap between itself and the inner wall of the bumper 200 when the bumper 200 is in its initial state, the gap ranging from 0 mm to 2 mm. For example, when the bumper 200 is in its initial state, the gap between the bumper 200 and the collision detection component 400 can be 0 mm, 0.5 mm, 1 mm, 1.5 mm, or 2 mm, etc.

[0050] like Figure 1 , Figure 4 and Figure 5As shown, in one embodiment, a mounting cavity 130 is provided on the front side of the movable body 100, and the mounting cavity 130 has an opening 131 extending to the front wall of the movable body 100. The collision detection assembly 400 includes a collision link 410, a second elastic element 420 and an optocoupler switch 430 mounted in the mounting cavity 130. The second elastic element 420 is connected to the collision link 410. The second elastic element 420 is configured to apply a reset force to the collision link 410 to reset the collision link 410 when the anti-collision plate 200 is in a collision state. The collision link 410 includes a pivot 411 and a first end 412 and a second end 413 disposed on opposite sides of the pivot 411. The pivot 411 is rotatably mounted in the mounting cavity 130. The first end 412 passes through the opening 131 and is disposed corresponding to the inner wall of the anti-collision plate 200. The second end 413 is configured to extend into the optocoupler switch 430 to block the light path when the anti-collision plate 200 is in the initial state, and to move out of the optocoupler switch 430 when the anti-collision plate 200 is in the collision state, so that the light path of the optocoupler switch 430 is turned on and a collision signal is generated.

[0051] When the anti-collision plate 200 is in its initial state, the second elastic element 420 provides a rotational preload to the collision link 410, causing the second end 413 of the collision link 410 to extend into the optocoupler switch 430 to block its optical path. At this time, the optocoupler switch 430 does not generate a collision signal. When the anti-collision plate 200 collides, the collision link 410 rotates after being impacted by the inner wall of the anti-collision plate 200. The second end 413 of the collision link 410 moves out of the optocoupler switch 430, so that the optical path of the optocoupler switch 430 is opened and a collision signal is generated. Subsequently, the collision link 410 resets under the force of the second elastic element 420. Thus, when the anti-collision plate 200 needs to reset, both the first elastic element 300 and the second elastic element 420 can provide a reset force, ensuring that the anti-collision plate 200 can accurately and reliably reset to its initial state, improving the reliability of the collision reset structure 10.

[0052] It should be noted that the shape and size of the first end 412 and the second end 413 can be flexibly designed according to the actual needs of use.

[0053] Optionally, when the crash barrier 200 contacts the first end 412, the first end 412 contacts the crash barrier 200 perpendicularly in the horizontal direction (e.g., Figure 4 (As shown by the dashed line). This reduces accidental activation and improves the reliability of the collision reset structure 10. For example... Figure 4 and Figure 5 As shown, the second elastic element 420 is further configured as a torsion spring. The torsion spring is sleeved on the rotating shaft 411, with one end of the torsion spring abutting against the inner wall of the mounting cavity 130 and the other end connected to the second end 413. In this way, one end of the torsion spring abuts against the inner wall of the mounting cavity 130 for limiting, eliminating the need for a separate fixing and limiting structure, thus improving the assembly convenience of the collision reset structure 10.

[0054] Specifically, in this embodiment, the rotating shaft 411 has a central hole. A torsion spring is located between the bottom wall of the mounting cavity 130 and the rotating shaft 411. The opposite sides of the torsion spring along its own axis are respectively fitted with the bottom wall of the mounting cavity 130 and the end face of the rotating shaft 411. The collision detection assembly 400 also includes a pan head screw 450, which passes through the central hole and the torsion spring and connects to the bottom wall of the mounting cavity 130, so as to rotatably mount the collision linkage 410 onto the moving body 100.

[0055] like Figure 4 and Figure 5 As shown, optionally, the inner wall of the mounting cavity 130 is provided with a third limiting part 132. The third limiting part 132 is configured to limit the engagement with the second end 413 when the anti-collision plate 200 is in the initial state. Thus, when the anti-collision plate 200 is in the initial state, the torsion spring provides rotational preload to the collision link 410, and the collision link 410 is stationary under the limitation of the third limiting part 132, and can stably and reliably block the optical path of the optocoupler switch 430, ensuring that the collision detection component 400 does not generate a collision signal when the anti-collision plate 200 is in a non-collision state (i.e., the initial state), thereby improving the reliability of the collision reset structure 10.

[0056] like Figure 4 and Figure 5 As shown, in one embodiment, the collision detection assembly 400 further includes a sealing ring 440. The sealing ring 440 is sleeved on the first end 412 and seals the inner wall of the mounting cavity 130 with the outer wall of the first end 412. Thus, the sealing ring 440 can prevent foreign objects from entering the side of the mounting cavity 130 where the optocoupler switch 430 is mounted, avoiding interference from foreign objects on the optocoupler switch 430 and improving the reliability of the collision reset structure 10.

[0057] like Figure 4 and Figure 5As shown, optionally, the movable body 100 includes a base 140 with a first mounting groove 141 on its top wall and a face shell 150 with a second mounting groove on its bottom wall. The face shell 150 is mounted on the base 140, such that the first mounting groove 141 and the second mounting groove cooperate to form a mounting cavity 130. The inner wall of the first mounting groove 141 has a first snap-fit ​​portion 142. The inner wall of the second mounting groove has a second snap-fit ​​portion. The outer wall of the sealing ring 440 has an annular groove 441, and the opposite sides of the annular groove 441 respectively engage with the first snap-fit ​​portion 142 and the second snap-fit ​​portion. Thus, during assembly, the sealing ring 440 is first fitted onto the first end 412 of the collision connecting rod 410, then one side of the annular groove 441 of the sealing ring 440 is correspondingly engaged with the first engaging part 142 in the first mounting groove 141, and finally the face shell 150 is correspondingly mounted on the base 140, so that the second engaging part in the second mounting groove is correspondingly engaged with the other side of the annular groove 441 of the sealing ring 440 to perform secondary fixation of the sealing ring 440, thereby improving the assembly convenience of the collision reset structure 10.

[0058] In one embodiment, another collision reset structure 10 is provided, including a movable body 100, a crash barrier 200, and a first elastic member 300. The crash barrier 200 is movably mounted on the front side of the movable body 100 in multiple directions. The inner wall of the crash barrier 200 has a mounting portion 110, and the mounting portion 110 has a first limiting portion 120. The first elastic member 300 is located between the movable body 100 and the crash barrier 200, and includes a sleeve portion 310, a second limiting portion 320, and an elastic abutment portion 330 disposed on the sleeve portion 310. The sleeve portion 310 is sleeved on the mounting portion 110 and is limited in engagement with the mounting portion 110 along an assembly direction perpendicular to the sleeve portion 310. The second limiting portion 320 is configured to limit the engagement with the first limiting portion 120 along the assembly direction when the sleeve portion 310 is sleeved on the mounting portion 110. The elastic abutment portion 330 abuts against the movable body 100.

[0059] The working principle of the collision reset structure 10 in this embodiment is the same as or similar to that of the collision reset structure 10 in the above embodiments. Furthermore, the collision reset structure 10 in this embodiment can also adopt the technical solutions of any of the above embodiments and achieve the corresponding technical effects, which will not be elaborated further here.

[0060] In one embodiment, a sweeping machine is provided, including the collision reset structure 10 of any of the above embodiments. Thus, the sweeping machine including the collision reset structure 10 achieves the corresponding technical effect, improving the reliability and ease of assembly of the sweeping machine.

[0061] In other embodiments, the collision reset structure 10 can also be applied to other mobile devices such as transport robots.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0064] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0065] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0066] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0067] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
