In order to prevent the sweeper from colliding with obstacles in blind spots that cannot be identified by the intelligent obstacle avoidance sensor, the sweeper is generally equipped with an anti-collision plate assembly in the front as a mechanical obstacle avoidance. After being hit by an obstacle, the anti-collision plate will trigger the collision connecting rod on the back of it, generate an electrical signal, and then return to the initial position under the action of the reset structure. The reset structure in the prior art may not be reset in place or centered during actual use, affecting the sensitivity of the mechanical obstacle avoidance. Summary of the invention

[0032] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by 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 mobile body 100, an anti-collision plate 200 and a first elastic member 300. Among them, a mounting portion 110 is provided on the front side of the mobile body 100, and a first limiting portion 120 is provided on the mounting portion 110. The anti-collision plate 200 can be movably mounted on the front side of the mobile body 100. The first elastic member 300 is located between the mobile body 100 and the anti-collision plate 200, and includes a sleeve portion 310, a second limiting portion 320 and an elastic abutting portion 330 provided on the sleeve portion 310. The sleeve portion 310 is sleeved on the mounting portion 110, and is limitedly matched with the mounting portion 110 along the assembly direction perpendicular to the sleeve portion 310. The second limiting portion 320 is configured to be limitedly matched with the first limiting portion 120 along the assembly direction when the sleeve portion 310 is sleeved on the mounting portion 110. The elastic abutting portion 330 abuts against the anti-collision plate 200.

[0034] In the collision reset structure 10 in the above embodiment, when in use, the elastic abutment portion 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 walking of the mobile body 100, and can also provide a reset force for the anti-collision plate 200 when the anti-collision plate 200 is in a collision state, and after the anti-collision plate 200 is reset, the amplitude of vibration is reduced under the action of the pre-tightening force, thereby reducing noise, thereby ensuring that the anti-collision plate 200 can be accurately and reliably reset to the initial state, thereby improving the reliability of the collision reset structure 10. In addition, the present application sleeves the sleeve portion 310 on the mounting portion 110 by sleeve connection, and when the sleeve portion 310 is sleeved on the mounting portion 110, the first limiting portion 120 and the second limiting portion 320 also correspond to the limiting cooperation, so that the first elastic member 300 is stably and reliably fixed on the front side of the mobile body 100, the operation is simple and convenient, and the assembly convenience of the collision reset structure 10 is improved.

[0035] The mounting portion 110 may be configured as a mounting rib, a mounting seat, a mounting block or other mounting structures. The mounting portion 110 may be configured upward or downward. The assembly direction of the sleeve portion 310 refers to the assembly and disassembly direction of the sleeve portion 310. Specifically in this embodiment, the assembly direction of the sleeve portion 310 may be configured as an up-down direction (e.g., Figure 2 The mounting portion 110 is arranged upward, and the sleeve portion 310 is assembled on the mounting portion 110 from top to bottom. The assembly direction perpendicular to the sleeve portion 310 refers to the direction perpendicular to A. Specifically, when the direction indicated by A is the up-down direction, the assembly direction perpendicular to the sleeve portion 310 is the horizontal direction. In other embodiments, the assembly direction of the sleeve portion 310 can also be set to an inclined direction, a left-right direction, a front-back direction, etc.

[0036] The anti-collision plate 200 can be installed on the front side of the mobile body 100 by any connection method in the prior art that can be moved in multiple directions. The anti-collision plate 200 can be installed on the front side of the mobile body 100 in a way that can be moved in multiple directions, which means that the anti-collision plate 200 is connected to the front side of the mobile body 100 along the front-to-back direction (such as Figure 1 In addition to moving and cooperating with the front side of the mobile body 100 in the up-down direction, moving and cooperating with the front side of the mobile body 100 in the left-right direction, or moving and cooperating with the front side of the mobile body 100 in both the up-down direction and the left-right direction.

[0037] Among them, the sleeve part 310, the second limiting part 320 and the elastic abutment part 330 can be made by an integral molding method, for example, the first elastic member 300 can be set as a spring sheet. The sleeve part 310 can be set as a closed ring structure, or it can be set as a non-closed ring structure. Specifically in this embodiment, the sleeve part 310 includes a sleeve body, and two fixing hooks respectively arranged on the left and right sides of the sleeve body. Along the assembly direction of the sleeve part 310, the projection area of ​​the sleeve part 310 is C-shaped.

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

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

[0040] like Figure 1 and Figure 3As shown, in one embodiment, the first limiting portion 120 is configured as a limiting card slot 121 and is disposed on the outer side wall of the mounting portion 110. The second limiting portion 320 is configured as a limiting card buckle 321, which is disposed at one end of the sleeve portion 310 away from the mobile body 100 and is at least partially located inside the sleeve portion 310. The limiting card buckle 321 is configured to extend into the limiting card slot 121 when the sleeve portion 310 is sleeved on the mounting portion 110, and to be limitedly matched with the inner side wall of the limiting card buckle 321. In this way, when the sleeve portion 310 is sleeved on the mounting portion 110, the limiting card buckle 321 is also correspondingly engaged with the limiting card slot 121, thereby improving the assembly convenience of the collision reset structure 10.

[0041] The limiting buckle 321 is at least partially located inside the sleeve portion 310 , which means that along the assembly direction of the sleeve portion 310 , the projection area of ​​the limiting buckle 321 is at least partially located inside the projection area of ​​the sleeve portion 310 .

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

[0043] like Figure 2 and Figure 3 As shown, in one embodiment, the number of the mounting portion 110 and the number of the first elastic member 300 are at least two. Each mounting portion 110 is arranged along the left-right direction (such as Figure 2 In the direction shown by C in the figure, the first elastic members 300 are arranged at intervals on the front side of the mobile body 100 and are arranged corresponding to each first elastic member 300. In this way, the first elastic members 300 are arranged at intervals along the left and right directions 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 collision reset, thereby improving the reliability of the collision reset structure 10.

[0044] The number of the mounting portions 110 and the number of the first elastic members 300 can be flexibly adjusted according to actual use requirements.

[0045] like Figure 2 As shown, optionally, there are two mounting parts 110 and two first elastic members 300. The mounting part 110 is symmetrically arranged on the front side of the mobile body. The two first elastic members 300 are arranged corresponding to the two mounting parts 110 and fixed on the front side of the mobile body 100 symmetrically.

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

[0047] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, the collision reset structure 10 further includes a collision detection assembly 400. The collision detection assembly 400 is installed on the front side of the mobile body 100, and is configured to be arranged corresponding to the inner wall of the collision plate 200 when the 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 collision plate 200 when the collision plate 200 is in the collision state and generate a collision signal.

[0048] Among them, the collision detection component 400 can be set to any structure in the prior art that can convert the collision condition into a collision signal (such as an electrical signal). The number and installation position of the collision detection components 400 can be flexibly adjusted according to the needs of actual use. Specifically in this embodiment, the number of collision detection components 400 is two, and the two collision detection components 400 are symmetrically arranged on the front side of the mobile body 100. In this way, the anti-collision plate 200 maintains a spacing arrangement or only contacts with the two collision detection components 400 when in the initial state, preventing the collision from one side from causing the detection component on the other side to be triggered due to the overall rotation of the anti-collision plate 200, reducing the possibility of false triggering of the collision detection component 400, and improving the reliability of the collision reset structure 10.

[0049] Optionally, the collision detection assembly 400 is configured to have a gap between the collision plate 200 and the inner wall of the collision plate 200 when the collision plate 200 is in the initial state, and the gap ranges from 0 mm to 2 mm. For example, when the collision plate 200 is in the initial state, the gap between the collision plate 200 and the collision detection assembly 400 may 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 mobile body 100, and the mounting cavity 130 has an opening 131 extending along the front wall of the mobile body 100. The collision detection assembly 400 includes a collision link 410, and a second elastic member 420 and an optical coupler switch 430 installed in the mounting cavity 130. The second elastic member 420 is connected to the collision link 410. The second elastic member 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 rotating shaft 411 and a first end 412 and a second end 413 arranged on opposite sides of the rotating shaft 411. The rotating shaft 411 is rotatably installed in the mounting cavity 130. The first end 412 passes through the opening 131 and is arranged corresponding to the inner wall of the anti-collision plate 200. The second end 413 is configured to extend into the optical coupler switch 430 to block the light path when the anti-collision plate 200 is in the initial state, and to move out of the optical coupler switch 430 when the anti-collision plate 200 is in the collision state, so as to open the light path of the optical coupler switch 430 and generate a collision signal.

[0051] When the anti-collision plate 200 is in the initial state, the second elastic member 420 provides a rotational pre-tightening force for the collision link 410, so that the second end 413 of the collision link 410 extends into the optical coupler switch 430 to block its optical path, and the optical coupler switch 430 does not generate a collision signal at this time. When the anti-collision plate 200 collides, the collision link 410 rotates after being hit by the inner wall of the anti-collision plate 200, and the second end 413 of the collision link 410 moves out of the optical coupler switch 430, so that the optical path of the optical coupler switch 430 is turned on and a collision signal is generated, and then the collision link 410 is reset under the action of the second elastic member 420. In this way, when the anti-collision plate 200 needs to be reset, the first elastic member 300 and the second elastic member 420 can both provide a reset force to ensure that the anti-collision plate 200 can be accurately and reliably reset to the initial state, thereby improving the reliability of the collision reset structure 10.

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

[0053] Optionally, when the anti-collision plate 200 contacts the first end 412, the first end 412 contacts the anti-collision plate 200 vertically in the horizontal direction (eg, Figure 4 In this way, the accidental touch is reduced and the reliability of the collision reset structure 10 is improved. Figure 4 and Figure 5 As shown, further, the second elastic member 420 is configured as a torsion spring. The torsion spring is sleeved on the rotating shaft 411, one end of the torsion spring abuts against the inner wall of the installation cavity 130, and the other end is connected to the second end 413. In this way, one end of the torsion spring abuts against the inner wall of the installation cavity 130 to limit the position, and no separate fixed limiting structure is required, thereby improving the assembly convenience of the collision reset structure 10.

[0054] Specifically in this embodiment, the rotating shaft 411 is provided with a center hole. The torsion spring is located between the bottom wall of the installation cavity 130 and the rotating shaft 411. The torsion spring is respectively limitedly matched with the bottom wall of the installation cavity 130 and the end face of the rotating shaft 411 on two opposite sides along its own axial direction. The collision detection assembly 400 also includes a pan head screw 450, which passes through the center hole and the torsion spring and is connected to the bottom wall of the installation cavity 130, so that the collision link 410 can be rotatably installed on the mobile 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 portion 132. The third limiting portion 132 is configured to cooperate with the second end 413 when the anti-collision plate 200 is in the initial state. In this way, when the anti-collision plate 200 is in the initial state, the torsion spring provides a rotational preload force for the collision link 410, and the collision link 410 is in a stationary state under the limitation of the third limiting portion 132, and can stably and reliably block the optical path of the optical coupling 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 installation cavity 130 with the outer wall of the first end 412. In this way, the sealing ring 440 can prevent foreign matter from entering the side of the installation cavity 130 where the optical coupler switch 430 is installed, thereby preventing the optical coupler switch 430 from being interfered by foreign matter and improving the reliability of the collision reset structure 10.

[0057] like Figure 4 and Figure 5As shown, optionally, the mobile body 100 includes a base 140 having a first mounting groove 141 on the top wall, and a face shell 150 having a second mounting groove on the bottom wall. The face shell 150 is mounted on the base 140 so that the first mounting groove 141 cooperates with the second mounting groove to form a mounting cavity 130. The first mounting groove 141 has a first clamping portion 142 on the inner wall. The second mounting groove has a second clamping portion on the inner wall. The outer wall of the sealing ring 440 has an annular clamping groove 441, and the opposite sides of the annular clamping groove 441 are respectively clamped and matched with the first clamping portion 142 and the second clamping portion. In this way, when the sealing ring 440 is assembled, the sealing ring 440 is first sleeved on the first end 412 of the collision link 410, and then one side of the annular groove 441 of the sealing ring 440 is correspondingly clamped on the first clamping portion 142 in the first installation groove 141, and finally the surface shell 150 is correspondingly installed on the base 140, so that the second clamping portion in the second installation groove is correspondingly clamped with the other side of the annular groove 441 of the sealing ring 440 to perform secondary fixation on 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, comprising a mobile body 100, an anti-collision plate 200 and a first elastic member 300. The anti-collision plate 200 is mounted on the front side of the mobile body 100 in a movable manner in multiple directions. The inner wall of the anti-collision plate 200 is provided with a mounting portion 110, and the mounting portion 110 is provided with a first limiting portion 120. The first elastic member 300 is located between the mobile body 100 and the anti-collision plate 200, and comprises a sleeve portion 310, a second limiting portion 320 and an elastic abutting portion 330 provided on the sleeve portion 310. The sleeve portion 310 is sleeved on the mounting portion 110, and is limitedly matched with the mounting portion 110 along the assembly direction perpendicular to the sleeve portion 310. The second limiting portion 320 is configured to be limitedly matched with the first limiting portion 120 along the assembly direction when the sleeve portion 310 is sleeved on the mounting portion 110. The elastic abutting portion 330 abuts against the mobile body 100.

[0059] The working principle of the collision reset structure 10 in this embodiment is the same or similar to that of the collision reset structure 10 in the above embodiment. In addition, the collision reset structure 10 in this embodiment can also adopt the technical solution in any of the above embodiments and achieve the corresponding technical effect, which will not be repeated here.

[0060] In one embodiment, a sweeping machine is provided, comprising the collision reset structure 10 in any of the above embodiments. Thus, the sweeping machine comprises the technical solution of the collision reset structure 10 and can achieve corresponding technical effects, thereby improving the reliability and assembly convenience of the sweeping machine.

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

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0065] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0066] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, 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 implementation method.

[0067] It should also be understood that when explaining the connection relationship or positional relationship of elements, although not explicitly described, the connection relationship and positional relationship are interpreted as including an error range, which should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" may mean within one or more standard deviations, which are not limited here.

[0068] The technical features of the above embodiments may be combined arbitrarily.
