Description
TECHNICAL FIELD
[0001] The utility model relates to robot transmission field more particularly, relate to a kind of tensile track structure and swimming pool cleaning robot. BACKGROUND
[0002] Leaves, branches, sand, household garbage and other impurities will fall during the use of swimming pool, pollute the swimming pool and affect water quality. The traditional cleaning method of swimming pool is manual cleaning, but manual cleaning is time-consuming and laborious, and the cost is also relatively large. The current cleaning method is mainly intelligent underwater robot cleaning method. Underwater robot, also known as unmanned remote control submersible, is an extreme operation robot working underwater. Intelligent underwater robot mainly sucks pool water through the built-in filter assembly and water pump, filters garbage, and then discharges pool water, thereby achieving pool cleaning. After cleaning, the underwater robot can return to the ground from underwater by climbing or climbing the wall.
[0003] Swimming pool cleaning robots usually have wheeled walking mechanisms and tracked walking mechanisms. The tracked walking mechanism usually drives the track to walk by cooperating with the transmission wheel. Generally speaking, in order to reduce weight, the thickness of the track is usually thin, which leads to low tensile strength of the track. After a long time of use, the track will age, causing the track to become longer and fall off, which will affect the normal operation of the swimming pool robot, and the service life of the track is short, which will also increase the use cost of the user. SUMMARY
[0004] The utility model aims at overcoming at least one defect (shortcoming) of the prior art, providing a tensile track structure and swimming pool cleaning robot, and improving the tensile performance of the track structure.
[0005] The utility model takes the technical scheme that a tensile track structure is provided, which comprises a track body. The track body is driven by a transmission wheel. A synchronous belt is arranged around the inner side of the track body. The synchronous belt is provided with inner protruding teeth. The inner protruding teeth are used for meshing transmission with the recesses of the transmission wheel. The synchronous belt is embedded with a reinforcing structure.
[0006] In the technical solution, the transmission wheel drives the track main body to move, the transmission wheel is a wheel structure with a recess, and the transmission wheel is in meshing transmission with the inner protruding teeth through the recess. The reinforcing structure can be a material capable of enhancing the tensile resistance of the synchronous belt, including but not limited to a fiber strip, a cotton cloth strip, or a polyester mesh, and more specifically, the fiber strip can be a Kevlar fiber strip. The material of the synchronous belt includes but is not limited to rubber; the material of the track main body includes but is not limited to rubber (NBR). The synchronous belt is provided with the reinforcing structure, so that the tensile resistance of the synchronous belt is enhanced. The track main body is provided with the synchronous belt, so that the durability is improved, the transmission wheel is prevented from loosening due to easy aging and deformation of the track, and the service life of the track is prolonged. In addition, the reinforcing structure is arranged in the synchronous belt instead of the entire track main body, so that the material is saved and the production cost is saved on the premise of improving the tensile resistance of the track. Furthermore, the thickness of the synchronous belt can be set to locally thicken the track main body, so as to increase the tensile resistance of the track according to actual needs.
[0007] Further, the inner side of the track main body is provided with a groove, and the synchronous belt is connected in the groove.
[0008] In the technical solution, the groove is a structure arranged along the circumferential direction of the inner side of the track. Through the arrangement of the groove, the material of the track main body is reduced, the weight of the track main body is reduced, the track main body is more flexible and convenient to carry, the overall machine weight is reduced to improve fuel economy, and the production cost is saved. The synchronous belt is arranged in the groove, so that the overall structure is more compact, and the volume of the entire track structure is reduced.
[0009] Further, a side stop ring is arranged along the side edge of the track main body.
[0010] In the technical solution, the side stop ring is a structure protruding inward from the radial direction, which has a certain limiting effect on the transmission wheel, prevents the transmission wheel from being misaligned or even separated from the track main body during rotation, and ensures the normal operation of the transmission wheel.
[0011] Further, the side stop ring is provided with a side protruding tooth, and the protruding direction of the side protruding tooth is the same as the protruding direction of the inner protruding tooth.
[0012] In the technical solution, the protruding directions of the side protruding teeth and the inner protruding teeth are both radially inward. The side protruding teeth can be matched with the concave-convex structure on the transmission wheel for transmission, and on the basis of the matching of the inner protruding teeth with the concave part of the transmission wheel, the matching degree of the transmission wheel and the track is further improved, so as to improve the transmission efficiency. On the other hand, the setting of the side protruding teeth plays a role in preventing the transmission wheel from being detached, and further ensures the normal operation of the transmission wheel. Further, the side protruding teeth are also provided with inclined sides in the circumferential direction of the track body, and when the side protruding teeth are matched with the concave-convex structure of the transmission wheel, the inclined sides can play a guiding role. Preferably, the thickness of the side protruding teeth gradually increases from top to bottom, and the side pressing structure is formed by extending from the side protruding teeth to the lower side to press the edge of the synchronous belt. The gradual change of the thickness can also guide the transmission wheel, and facilitate the matching of the concave-convex structure on the transmission wheel with the side protruding teeth.
[0013] Further, at least part of the side retaining ring is pressed on the edge of the synchronous belt.
[0014] In the technical solution, the edge of the synchronous belt close to the side retaining ring is embedded in the side retaining ring. In this way, the connection between the synchronous belt and the track body is more firm, the structure is more compact, and the stability of the track structure during operation is further ensured. Specifically, one side wall of the groove is the side retaining ring, the side protruding teeth are integrally connected to the top of the side retaining ring, and the thickness of the side protruding teeth gradually increases from top to bottom, and the side pressing structure is formed by extending from the side protruding teeth to the lower side to press the edge of the synchronous belt.
[0015] Further, the inner protruding teeth are provided with two inclined surfaces in the circumferential direction of the track body, and the top surface area of the inner protruding teeth is smaller than the bottom surface area.
[0016] In the technical solution, the two inclined surfaces are oppositely arranged, the cross section of the inner protruding teeth is in the shape of a trapezoid, preferably an isosceles trapezoid, and the appearance is increased. The setting of the two inclined surfaces plays a guiding role on the concave part of the transmission wheel, facilitates the engagement of the transmission wheel and the track body, and ensures the smooth transmission.
[0017] Further, the track body is integrally formed by injection molding. The contact surface of the synchronous belt and the groove is a rough surface, and the synchronous belt and the track body are connected by an adhesive process.
[0018] In the technical solution, the integral forming of the track main body enhances the stability of the overall structure. The contact surface of the synchronous belt and the groove is rough, and the rough surface is combined with glue to greatly improve the firmness of the bonding, so that when the transmission wheel bears a large weight, the track main body and the synchronous belt on the track will not be loose, thereby ensuring the stability of the machine operation. The firm connection of the track main body and the synchronous belt can further enhance the tensile performance of the track structure and prolong the service life. For example, during production and processing, the outer surface of the synchronous belt is polished to form a rough surface, coated with glue, and then placed in the injection mold of the track main body for injection molding of the track main body.
[0019] Further, the outer surface of the track main body is also provided with spaced apart outer protrusions. The outer protrusions can increase the friction of the outer surface, improve the stability of the track main body, and increase the overall thickness of the track structure to enhance the support strength of the track.
[0020] Another object of the present application is to provide a pool cleaning robot, comprising a robot main body and a transmission wheel connected by rotation, and a tensile track structure of any of the above, wherein the groove of the transmission wheel is engaged with the inner protrusions.

[0035] The reinforcing structure can be a material capable of enhancing the tensile strength of the synchronous belt 200, including but not limited to a fiber strip, a cotton cloth strip, or a polyester mesh, and more specifically, the fiber strip can be a Kevlar fiber strip. The material of the synchronous belt 200 includes but is not limited to rubber; the material of the track body 100 includes but is not limited to rubber (NBR). The synchronous belt 200 is provided with a reinforcing structure, so that the tensile strength of the synchronous belt 200 is enhanced. The track body 100 is provided with the synchronous belt 200, so that the durability is improved, the track is less likely to be aged and deformed, the driving wheel is less likely to be loose, and the service life of the track is prolonged. In addition, the reinforcing structure is arranged in the synchronous belt 200 instead of the entire track body 100, so that the tensile strength of the track is improved while the weight of the track is reduced.
[0036] Specifically, the inner convex teeth 210 are arranged at intervals to provide a meshing space for the driving wheel.
[0037] In order to reduce the weight of the track, the inner side of the track body 100 is provided with a groove 110, and the synchronous belt 200 is connected in the groove 110. The groove 110 is a structure arranged along the circumference of the inner side of the track. By arranging the groove 110, the material of the track body 100 is reduced, the weight of the track body 100 is reduced, the track body 100 is more flexible and convenient to carry, the overall weight is reduced, the fuel economy is improved, and the production cost is saved. The synchronous belt 200 is arranged in the groove 110, so that the overall structure is more compact, and the volume of the entire track structure is reduced.
[0038] In order to prevent the driving wheel from falling off, a side stop ring 120 is arranged along the side of the track body 100. The side stop ring 120 is a structure protruding inward from the radial direction, which has a limiting effect on the driving wheel, prevents the driving wheel from being dislocated or even separated from the track body 100 during rotation, and ensures the normal operation of the driving wheel.

It can be understood that the protruding direction of the side protruding tooth 121 and the inner protruding tooth 210 is radially inward. The side protruding tooth 121 can match the concave-convex structure on the transmission wheel for transmission, and further improve the matching degree of the transmission wheel and the track on the basis of the cooperation between the inner protruding tooth 210 and the transmission wheel recess, so as to improve the transmission efficiency.

Specifically, one side wall of the groove 110 is the side stop ring 120, the side protruding tooth 121 is integrally connected to the top of the side stop ring 120, and the thickness of the side protruding tooth 121 gradually increases from top to bottom.

[0041] In order to facilitate the matching of the transmission wheel and the inner protruding tooth 210, the inner protruding tooth 210 is provided with two inclined surfaces 211 in the circumferential direction of the track body 100, and the top surface area of the inner protruding tooth 210 is smaller than the bottom surface area. Specifically, the two inclined surfaces 211 are oppositely arranged, and the cross section of the inner protruding tooth 210 is in the shape of a trapezoid, preferably an isosceles trapezoid, which increases the aesthetic appearance. The arrangement of the two inclined surfaces 211 plays a guiding role for the recess on the transmission wheel, facilitates the engagement of the transmission wheel and the track body 100, and ensures the smooth transmission.

The contact surface of the synchronous belt 200 and the groove 110 is rough, and the synchronous belt 200 and the track body 100 are connected by an adhesive process. The integrally formed track body 100 enhances the stability of the overall structure. The rough surface of the contact surface of the synchronous belt 200 and the groove 110, compared to the smooth surface, can greatly improve the firmness of the adhesive, so that when the transmission wheel bears a large weight, it will not loosen the track body 100 and the synchronous belt 200 on the track, thereby ensuring the stability of the machine operation; the firm connection of the track body 100 and the synchronous belt 200 can further enhance the tensile performance of the track structure and prolong its service life.
