[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] Please refer to Figures 1 to 6 As shown, in an embodiment of the present invention, a front collision assembly is provided, which is applied to a cleaning robot. The front collision assembly includes a front collision body 100 and an elastic member 200. The elastic member 200 is provided with two rear ends which are respectively arranged on both sides of the front collision body 100. The elastic member 200 is an integrally formed structure, and has a first rebound portion 250 and a second rebound portion 260 which abut against the front collision body 100. The first rebound portion 250 is used to receive the first pressure transmitted by the front collision body 100, and can apply a first reaction force F1 in the opposite direction of the first pressure to the front collision body 100. The second rebound portion 260 is used to receive the second pressure transmitted by the front collision body 100, and can apply a second reaction force F2 in the opposite direction of the second pressure to the front collision body 100. The first pressure is the pressure in the direction of travel of the cleaning robot, and the second pressure is the lateral pressure set perpendicular to the direction of travel or at an acute angle. Specifically, the first pressure is the force received by the front collision body 100 in the front and rear directions, and the second pressure is the force received by the front collision body 100 in the left and right directions.

[0044] It should be noted that in this embodiment and the following embodiments, according to Figure 3 The XYZ rectangular coordinate system established in the definition is: the side located in the positive direction of the X axis is defined as the front, and the side located in the negative direction of the X axis is defined as the back; the side located in the positive direction of the Y axis is defined as the left, and the side located in the negative direction of the Y axis is defined as the right; the side located in the positive direction of the Z axis is defined as the top, and the side located in the negative direction of the Z axis is defined as the bottom.

[0045] The rebound principle of the front collision assembly provided in this embodiment is as follows:

[0046] When in use, the front collision body 100 and the elastic member 200 in the front collision assembly are respectively installed on the main body of the cleaning robot, so that the front collision body 100 has the freedom to move forward and backward and left and right relative to the cleaning robot main body 500, and the elastic member 200 is fixedly installed on the cleaning robot main body 500, and abuts against the inner wall of the front collision body 100 through the first rebound part 250 and the second rebound part 260.

[0047] When the cleaning robot encounters an obstacle during operation, since the front collision component is located at the front end of the cleaning robot body 500, it will first contact the obstacle and, under the push of the obstacle, move closer to the cleaning robot body 500 to trigger the collision detection mechanism located on the cleaning robot body 500.

[0048] In the above process, if the area between the obstacle and the front collision body 100 is the front surface of the front collision body 100, the direction of the thrust received by the front collision body 100 is in the moving direction of the cleaning robot. At this time, the first rebound part 250 in the elastic part 200 receives the first pressure corresponding to the above thrust, and then deforms, and applies a first reaction force F1 to the front collision body 100 that is opposite to the direction of the first pressure.

[0049] If the area between the obstacle and the front collision body 100 is on the left side of the front collision body 100, the direction of the thrust received by the front collision body 100 is perpendicular to the moving direction of the cleaning robot or is set at an acute angle, and the second rebound part 260 in the elastic part 200 located on the left side of the front collision body 100 receives a second pressure corresponding to the above-mentioned thrust, and then deforms, and applies a second reaction force F2 toward the left side to the front collision body 100.

[0050] If the area between the obstacle and the front collision body 100 is on the right side of the front collision body 100, the direction of the thrust received by the front collision body 100 is perpendicular to the moving direction of the cleaning robot or is set at an acute angle, and the second rebound part 260 in the elastic part 200 located on the right side of the front collision body 100 receives a second pressure corresponding to the above-mentioned thrust, and then deforms, and applies a second reaction force F2 toward the right side to the front collision body 100.

[0051] The first reaction force F1 and the second reaction force F2 are respectively used to keep the front collision body 100 and the cleaning robot body 500 within a preset distance when the front collision body 100 does not receive an external thrust, and are also used to push the front collision body 100 back to its original position when the external wall thrust is withdrawn.

[0052] It should be noted that in the above steps, in the initial state, the first rebound portion 250 and the second rebound portion 260 in the elastic member 200 may only contact the front collision body 100 but not apply any force to it; or the first rebound portion 250 and the second rebound portion 260 may be in a pre-stressed state in the initial state, and apply the first reaction force F1 and the second reaction force F2 to the front collision body 100, so as to maintain a preset distance between the front collision body 100 and the cleaning robot body 500.

[0053] The front collision assembly provided by the embodiment of the present invention has elastic members 200 installed only at the rear ends of both sides of the front collision body 100, and the rebound structure installed on the front side of the front collision body 100 is cancelled. The elastic member 200 is integrally formed and has a first rebound portion 250 and a second rebound portion 260. Through the elastic member 200, only two are needed to realize the rebound of the front collision body 100 in the front-to-back direction and the rebound of the front collision body 100 in the left-to-right direction. Therefore, on the basis of ensuring its normal function, the number of elastic members 200 can be effectively reduced, the assembly is simplified, and the manufacturing cost of the front collision assembly and the cleaning robot is effectively reduced. In addition, the elastic member 200 in this embodiment is small in size and only occupies a little space at the left and right positions of the rear end of the front collision body 100. When applied to the cleaning robot, it can make full use of the structural space of the cleaning robot body 500 and is easy to assemble.

[0054] Please refer to Figure 5 As shown, in an optional embodiment, the elastic member 200 is formed by bending a strip, including a first bending portion 210, a spring portion 220 and a second bending portion 230 connected in sequence. The first bending portion 210 is used to connect with the main body of the cleaning robot. The second bending portion 230 extends from the end of the spring portion 220 to the side of the spring portion 220 to form a second rebound portion 260. The spring portion 220 is the first rebound portion 250. Specifically, the second bending portion 230 is suspended away from one end of the spring portion 220. In this way, when the second bending portion 230 receives the lateral pressure perpendicular to the direction of travel or arranged at an acute angle transmitted by the front collision body 100, it can bend, store energy and apply a second reaction force F2 to the front collision body 100. The elastic member 200 adopts the structure provided in this embodiment, which is simple, compact and stable in structure, easy to install, and has low manufacturing cost, achieving multiple goals at one stroke.

[0055] Please refer to Figure 6 As shown, in an optional embodiment, the elastic member 200 is formed by bending a sheet, and includes a first bending portion 210 and a second bending portion 230 connected to each other, the first bending portion 210 is used to connect to the main body of the cleaning robot, and the second bending portion 230 is a V-shaped structure with an opening toward the side where the first bending portion 210 is located, the V-shaped structure is a first rebound portion 250, and the free end of the V-shaped structure is a second rebound portion 260.

[0056] Specifically, the V-shaped structure body has the deformation ability to expand and contract along the first direction, and also has the deformation ability to rotate within a preset angle around the connection point between itself and the connection part. When in use, the top corner and the free end of the V-shaped structure are in contact with the front collision body 100 respectively. When the front collision body 100 receives a top thrust in the direction of travel, the top thrust is transmitted to the top corner of the V-shaped structure, pushing the entire V-shaped structure to bend inward around the connection point between itself and the connection part. The V-shaped structure stores energy through deformation and applies a first reaction force F1 to the front collision body 100. When the elastic member 200 receives a top thrust perpendicular to the direction of travel or set at an acute angle to the direction of travel, that is, lateral pressure, the free end of the V-shaped structure contracts inward and stores energy, while applying a second reaction force F2 to the front collision body 100.

[0057] The elastic member 200 adopts the structure provided by this embodiment, which is simple, compact and stable, easy to install and has low manufacturing cost, thus achieving multiple goals at one stroke.

[0058] Furthermore, in an optional embodiment, the sheet used for the elastic member 200 in the above embodiment is an irregular sheet, and the width of the area corresponding to the first bending portion 210 is greater than the width of the area corresponding to the second bending portion 230, so that there is a sufficiently large contact area between the first bending portion 210 and the cleaning robot body 500, thereby allowing the elastic member 200 to be stably connected to the cleaning robot. At the same time, the sheet size of the area corresponding to the first rebound portion 250 and the second rebound portion 260 is small, which is convenient for bending and rebounding, and meets the use requirements.

[0059] In an optional embodiment, the first bending portion 210 in the above embodiments is a sleeve portion, which is used to be sleeved on the main body of the cleaning robot. The first bending portion 210 adopts the structure provided by this embodiment, which is convenient for connection with the main body of the cleaning robot, and the connection structure is stable, which can effectively improve the assembly efficiency when the elastic member 200 and the main body of the cleaning robot are assembled.

[0060] Please refer to Figure 7 and Figure 8 As shown, in an optional embodiment, the front collision body 100 includes a transverse portion 110 and a longitudinal portion 120 respectively connected to the two ends of the transverse portion 110, and a first limiting structure 300 is formed on the free end of the longitudinal portion 120. The first limiting structure 300 includes a first limiting portion 310 and a second limiting portion 320. The first limiting portion 310 is protruded on the inner side wall of the longitudinal portion 120 for abutting against the first rebound portion 250, and the second limiting portion 320 is protruded on the end face of the longitudinal portion 120 along the length direction of the longitudinal portion 120 for abutting against the second rebound portion 260.

[0061] The front collision body 100 adopts the structure provided in this embodiment, which has a simple structure and can achieve fixation of the relative position with the first rebound part 250 and the second rebound part 260, thereby avoiding a large deviation of the contact point between the first rebound part 250 and / or the second rebound part 260 and the front collision body 100 during use, thereby affecting the rebound effect, thereby ensuring the stability of the working performance of the front collision component.

[0062] Please refer to Figure 7 and Figure 8 As shown, in an optional embodiment, the first limiting structure 300 also includes a support portion 330 formed between the first limiting portion 310 and the second limiting portion 320, and the support portion 330 is used to support the elastic member 200. Specifically, the support portion 330 can be a plate, a block, a rod, etc. connecting the first limiting portion 310 and the second limiting portion 320, as long as the elastic member 200 can be supported, and no sole limitation is made here. The provision of the support portion 330 avoids the relative position of the elastic member 200 and the front collision body 100 in the up and down directions from shifting during transportation or use, and further improves the stability of the working performance of the front collision assembly.

[0063] In a specific embodiment, the first limit portion 310, the second limit portion 320 and the support portion 330 are three mutually perpendicular plates. The first rebound portion 250 and the second rebound portion 260 in the elastic member 200 are both located in the space surrounded by the three plates. In this way, the first rebound portion 250 and the second rebound portion 260 have a large contact area with the corresponding limit portions, thereby ensuring the stability of the working performance of the front collision assembly. At the same time, the support portion 330 also has a large contact area with the elastic member 200, which can achieve stable support for the elastic member 200.

[0064] Furthermore, the support portion 330 connects the middle portion of the first limiting portion 310 and the middle portion of the second limiting portion 320 to limit the action portion of the elastic member 200 and the first limiting portion 310 and the second limiting portion 320 to the middle and upper portions of the first limiting portion 310 and the second limiting portion 320.

[0065] Please refer to Fig. 9 As shown, in another embodiment of the present invention, a cleaning robot is provided, comprising a cleaning robot body 500, a collision detection mechanism installed on the cleaning robot body 500, and a front collision assembly provided in the above embodiments. The cleaning robot in this embodiment can be a D-shaped cleaning robot or a cleaning robot of other models, as long as the front collision assembly provided in the corresponding embodiment can be applied, and no limitation is made here.

[0066] For details, please refer to Figure 7As shown, a fourth protrusion 140 for contacting the collision detection mechanism is convexly provided on the inner side wall of the front collision body 100. When the front collision body 100 is subjected to an external top thrust, it moves toward the cleaning robot body 500. During this period, the fourth protrusion 140 contacts and presses the collision detection mechanism to trigger the collision detection mechanism.

[0067] The cleaning robot provided by the embodiment of the present invention adopts the front collision assembly provided by the above-mentioned embodiments, and can realize the rebound of the front collision body 100 in the front-to-back direction and the rebound of the front collision body 100 in the left-to-right direction by using fewer elastic members 200, thereby effectively reducing the number of elastic members 200 on the basis of ensuring its normal function, simplifying the assembly, and effectively reducing the manufacturing cost of the front collision assembly and the cleaning robot. In addition, the elastic member 200 in this embodiment is small in size and only occupies a little space at the left and right positions of the rear end of the front collision body 100, making full use of the structural space of the cleaning robot body 500 and easy to assemble.

[0068] Please refer to Fig.10 As shown, in an optional embodiment, the cleaning robot body 500 includes a base 510 and an upper shell 520 mounted on the base 510, and an installation space 530 is formed between the upper shell 520 and the base 510, and a portion of the front collision body 100 is located in the installation space 530, and the other portion protrudes from the installation space 530. Generally, the front collision body 100 protrudes from the front surface of the upper shell 520 by more than 3mm. And the front collision body 100 can move relative to the upper shell 520 and the base 510 within a preset range. The collision detection mechanism and the elastic member 200 are both fixedly mounted on the base 510 and / or the upper shell 520.

[0069] Specifically, the front impact body 100 is movably installed between the upper shell 520 and the base 510, and can move within a certain range in the up-down direction, front-back direction, and left-right direction relative to the upper shell 520 and the base 510, that is, within the above-mentioned preset range. The preset range mentioned here can be set according to specific usage requirements and is not limited here.

[0070] The front collision body 100, the collision detection mechanism and the elastic member 200 can be connected to one of the base 510 and the upper shell 520, or to both of them. The specific selection can be flexibly made according to the installation and use requirements, and is not limited here. The front collision body 100 is installed on the cleaning robot body 500 using the structure provided in this embodiment, and can move within a preset range to reduce the risk of being damaged when it is hit and ensure the stability of its working performance.

[0071] Please refer to Figures 10 to 13As shown, in an optional embodiment, a second limiting structure and a third limiting structure 800 are formed between the base 510 and the upper shell 520, the second limiting structure is used to limit the movement range of the front collision body 100 in the vertical direction (i.e., the up and down direction), and the third limiting structure 800 is used to limit the movement range of the front collision body 100 in the horizontal plane.

[0072] Specifically, the third limiting structure 800 can be used to limit the movement range of the front impact body 100 in the front and rear directions and the left and right directions. Through the structure provided in this embodiment, the movement range of the front impact body 100 in the vertical direction and the horizontal plane can be limited respectively, which is easy to process and design.

[0073] In an optional embodiment, if Fig.11 As shown, the second limiting structure includes a first protrusion 700 protruding from the lower surface of the upper shell 520, the bottom surface of the first protrusion 700 is lower than the bottom surface of the upper shell 520, and the bottom surface of the first protrusion 700 abuts against the upper surface of the base 510;

[0074] Or, if Fig.12 As shown, the second limiting structure includes a first protrusion 700 protruding from the upper surface of the base 510 , the top surface of the first protrusion 700 is higher than the top surface of the base 510 , and the top surface of the first protrusion 700 abuts against the lower surface of the upper shell 520 .

[0075] Specifically, the first protrusion 700 can be a column, a block, a cone, etc., which can be set according to the use requirements, and is not limited here. After assembly, under the support of the first protrusion 700, the above-mentioned installation space 530 is formed between the upper shell 520 and the base 510. The overall structure is simple and easy to assemble.

[0076] Please refer to Figures 1 to 4 ,as well as Figure 7 As shown, in an optional embodiment, the front collision body 100 is provided with an avoidance hole 130 for the first protrusion 700 to pass through. During installation, the first protrusion 700 passes through the avoidance hole 130 and abuts against the upper shell 520 or the base 510 on the opposite side. In this way, the front collision body 100 can be limited between the upper shell 520 and the base 510 by the first protrusion 700, without the need for other structures, so that the overall structure of the cleaning robot is simple and easy to assemble.

[0077] Please refer to Figures 1 to 4 ,as well as Fig.13As shown, in an optional embodiment, the third limiting structure 800 includes a limiting plate 810 and a second protrusion 830. The limiting plate 810 is located on the inner side of the front collision body 100 and connected to the front collision body 100, and a through hole 820 is opened in the middle of the limiting plate 810. Specifically, the plate surface of the limiting plate 810 is parallel to the horizontal plane, or is set at an acute angle to the horizontal plane. The size of the through hole 820 is relatively large.

[0078] The second protrusion 830 is protruded from the lower surface of the upper shell 520 or the upper surface of the base 510, and at least part of the second protrusion 830 is located in the through hole 820. The cross-sectional area of ​​the through hole 820 is larger than the cross-sectional area of ​​the part of the second protrusion 830 located in the through hole 820.

[0079] When the front collision body 100 is subjected to an external force, the limiting plate 810 can be driven to move relative to the second protrusion 830, so that the position of the second protrusion 830 in the through hole 820 moves, and the movement can be forward and backward or left and right. When the inner wall of the through hole 820 abuts against the second protrusion 830, the front collision body 100 cannot continue to move inward under the obstruction of the second protrusion 830, thereby preventing the front collision body 100 from being damaged by the base 510 or the upper shell 520 when the external thrust force is large, thereby effectively improving the stability of the overall structure of the cleaning robot.

[0080] In a specific embodiment, the front ends of the upper shell 520 and the base 510 are connected by bolts, and the first protrusion 700 and the second protrusion 830 are bolt columns. In this way, the first protrusion 700 and the second protrusion 830 can have multiple functions, thereby reducing the number of protrusions on the upper shell 520 and the base 510, thereby reducing their production costs.

[0081] To reduce the friction between the front collision body 100 and the base 510 when the front collision body 100 moves relative to the base 510, please refer to Fig.14 As shown, in an optional embodiment, the upper surface of the base 510 is formed with a third protrusion 540 for supporting the front collision body 100. Specifically, the third protrusion 540 can be a convex ridge, a convex point, etc., which can be selected according to design requirements and is not limited here. The cleaning robot provided by this embodiment can effectively reduce the contact area of ​​the front collision body 100 with the base 510, reduce the friction of the front collision body 100 moving relative to the base 510, and improve the rebound flexibility of the front collision body 100.
