[0002] The main function of a floor sweeping robot is to clean floors, etc., which includes actions such as brushing, sweeping, and washing to achieve multi-functionality, but its most basic and core function is the sweeping action. During the process of sweeping the floor by the floor sweeping robot, the mop at its bottom brushes the floor, and the dust, garbage, etc. after brushing can be collected inside the floor sweeping robot through a dust suction mechanism, thereby automatically completing the cleaning work of the floor.

[0003] Since the mop needs to be in contact with the ground for a long time for brushing, it is easy to get dirty and needs to be replaced and cleaned frequently. In the prior art, for the mop installed on the mop tray at the bottom of the floor sweeping robot, a simple treatment method is to adhesively set magic tapes on the mop tray and the mop respectively, and the fixing of the mop is achieved through the connection between the hook surface and the loop surface of the magic tape. However, due to the need for frequent pulling, it is easy to pull out the hook wires on the magic tape (on the hook surface), and the fixing effect on the mop will be poor due to multiple or long-term damage to the hook surface; in addition, when the magic tape adhesively set on the mop tray has a weakened adhesive effect between the two, the magic tape may also be separated from the mop tray due to external force. The above situations will affect the normal brushing of the mop. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a connection structure between a mop tray and a mop of a floor sweeping robot. The hard hook surface of the first magic tape with a hard structure has better strength, which can avoid phenomena such as hook wire pulling out and falling off due to long-term use or multiple pulling actions of separating from the loop surface on the second magic tape, so that the first magic tape has a longer service life, and the installation of the first magic tape on the mop tray is more stable and accurate.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a connection structure between a mop tray and a mop of a floor sweeping robot, including:

[0026] The following are specific embodiments of the present utility model and in conjunction with the drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0027] As Figures 1 to 5 shown, a connection structure between a tray and a mop cloth of a floor sweeping robot includes a tray 10, a first magic tape 20 and a mop cloth 30. The tray 10 is arranged at the lower end of the floor sweeping robot. A plurality of slots 100 are provided on the tray 10. An upper part of the side wall of the slot 100 is provided with a clamping groove 101. There are a plurality of first magic tapes 20, which are of a rigid structure. The first magic tape 20 includes a rigid plate 21 and a rigid hook surface 22 formed in an array on the lower end surface of the rigid plate 21. A plurality of card heads 23 protruding horizontally from the rigid plate 21 are provided at the upper end of the rigid plate 21. The rigid plate 21 is embedded in the slot 100 and the card heads 23 are clamped in the clamping grooves 101. A plurality of second magic tapes 40 are pasted on the mop cloth 30. The second magic tapes 40 are of a conventional soft structure and have a fluffy surface. The second magic tapes 40 are fixed to the first magic tapes 20 to fix the mop cloth 30 to the lower end surface of the tray 10.

[0028] To replace the conventional method of connecting the magic tape to the lower end surface of the tray 10 through an adhesive layer, in the present utility model, the first magic tape 20 is of a rigid structure formed by injection molding in one piece, for example, it can be a rigid plastic, which has good rigidity and certain deformation recovery characteristics. By clamping the first magic tape 20 into the clamping groove 101 in the slot 100 on the tray 10 through the card heads 23 it has, the first magic tape can be fixed on the tray 10. Then, by making the fluffy surface structure of the second magic tape 40 act on the rigid hook surface 22 of the first magic tape 20, the mop cloth 30 can be fixed to the lower end surface of the tray 10.

[0029] In the present utility model, the first Velcro 20 which is injection-molded and has a rigid structure is used as the fixing part of the mop 30. On the one hand, the rigid hook surface 22 interacting with the second Velcro 40 has better strength. It is not easy to cause phenomena such as snagging and falling off like ordinary Velcro due to long-term use or repeated pulling during separation from the fuzzy surface on the second Velcro, and it has a longer service life. On the other hand, also due to its rigid structure, the chuck 23 on the first Velcro 20 can be connected to the mop tray 10 in a snap-fit manner, with better fixing effect. And due to the limiting effect of the slot 100 on the mop tray 10, it can ensure that the position of the first Velcro 20 on the mop tray 10 is more accurate, and can avoid phenomena such as poor adhesion like ordinary Velcro (which may be torn off and separated from the mop tray when replacing the mop) or inaccurate adhesion position (requiring repositioning and adhesion after tearing off, so it may also cause unstable adhesion due to repeated tearing). Moreover, the supporting effect of the rigid hook surface 22 can better support the mop 30, so that the mop 30 can be in full contact with the ground.

[0030] Preferably, the lower end surface of the rigid plate 21 and the end surface of the opening of the slot 100 are in the same plane, that is, the rigid hook surface 22 protrudes downward from the bottom end of the mop tray 10, which can ensure the connection effect between the first Velcro 20 and the second Velcro 40.

[0031] Furthermore, the rigid plate 21 is in interference fit with the side wall of the slot 100. On the one hand, it can ensure the installation stability of the first Velcro 20 in the slot 100. On the other hand, it can avoid forming a large gap between the rigid plate 21 and the slot 100, and can prevent dust and debris from entering between the two, resulting in difficult cleaning.

[0032] In addition, a slot 210 is provided on one side of the rigid plate 21 away from the rigid hook surface 22. By providing the slot 210, the height of the rigid plate 21 can be increased on the premise of saving injection molding materials, that is, the side area of the rigid plate 21 is increased. On the one hand, it can ensure that the top end of the first magic tape 20 abuts against the top wall of the slot 100 to ensure the supporting effect on the first magic tape 20. On the other hand, increasing the area of the interference fit with the side wall of the slot 100 can also ensure the installation stability. In addition, it should be noted that the setting of the slot 210 is equivalent to forming a frame structure in which four straight plates 211 are connected end to end at the upper part of the rigid plate 21. The chuck 23 is formed at the upper end of the frame structure, that is, on the straight plate 211. Since the straight plate 211 has a certain height, when the chuck 23 abuts against the side wall of the slot 100 and enters the slot 100, it can be deformed and tilted to a certain extent better through the straight plate 211, which is convenient for the chuck 23 to enter the slot 100. And after reaching the corresponding position, due to the deformation recovery of the straight plate 211, it enters the card slot 101; the end-to-end connection of the four straight plates 211 is conducive to mutual support for deformation recovery and maintaining the stability of the entire frame structure.

[0033] More preferably, the number of the chucks 23 is four, and the four chucks 23 are symmetrically arranged on the opposite sides of the upper end of the rigid plate 21, that is, two chucks 23 are provided on one straight plate 211, and a connecting plate 231 is formed between a pair of chucks 23 on the same side of the rigid plate 21. The lower end of the connecting plate 231 is connected to the rigid plate 21. By increasing the connection between the chucks 23, the strength of the chucks 23 can be enhanced.

[0034] Based on the above settings, there are two card slots 101, and the two card slots 101 are symmetrically arranged on the opposite side walls of the slot 100, and the card slot 101 extends from one side of the slot 100 to the other side, which is convenient for machining and forming the card slot 101 in the slot 100.

[0035] Again Figure 5 As shown, a first guiding arc surface 230 is provided at the upper end of the chuck 23. This structure is easy for the chuck 23 to extend into the slot 100, and a second guiding arc surface 11 is provided at the connection between the lower end of the card slot 101 and the slot 100. After the first magic tape 20 is subjected to an outward acting force (for example, by inserting a tool such as a rocker into the gap formed between the slot 100 and the side of the rigid plate 21 without the chuck 23), it is also convenient for the chuck 23 to disengage from the card slot 101 and enter the slot 100 and then disengage from the slot 100.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
