Description

Technical Field

[0001] The present application relates to the field of cleaning equipment, and in particular to a swimming pool cleaning machine and a driving system thereof. Background Art

[0002] Pool cleaning machines are automated equipment designed specifically to clean and maintain the hygiene of swimming pools. These machines remove dirt, debris and algae from the bottom and sides of the pool through efficient cleaning systems such as brushes, vacuums and filters.

[0003] In the prior art, pool cleaning machines usually rely on multiple rollers to achieve the movement of the machine. Each roller is equipped with an independent motor to drive it. This design means that for each additional roller, a motor and its related control and support structure are added accordingly. This configuration not only increases the weight and volume of the pool cleaning machine, but also increases energy consumption. More importantly, as the number of motors increases, the manufacturing cost and maintenance cost of the pool cleaning machine also increase accordingly. Utility Model Content

[0004] To this end, the present application provides a swimming pool cleaning machine and a driving system thereof to solve the problems of high energy consumption, heavy weight and large volume of swimming pool cleaning machines in the prior art.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A driving system of a swimming pool cleaning machine comprises a body, a plurality of driving components connected to the body and used to drive the body to move, the plurality of driving components are arranged at intervals along the length direction of the body, the driving component comprises a first driving shaft rotatably connected to one side of the width direction of the body and a second driving shaft rotatably connected to the other side of the width direction of the body, one end of the first driving shaft is connected to a first roller, and the other end is connected to a first bevel gear, one end of the first driving shaft is connected to a second roller, and the other end is connected to a second bevel gear, a third bevel gear is connected between the first bevel gear and the second bevel gear, one side of the third bevel gear is meshed with the first bevel gear, and the other side opposite to the third bevel gear is meshed with the second bevel gear, the first driving shaft and the second driving shaft are collinear, the first driving shaft is connected to a driving member for driving the first driving shaft to rotate, and the driving component also includes a locking member for controlling the self-rotation or self-rotation locking of the third bevel gear.

[0007] Optionally, the locking member includes a support rod connected to the second drive shaft and a rotating shaft connected to the third bevel gear, an end of the support rod away from the second drive shaft is provided with an axial hole for passing the rotating shaft, an end of the rotating shaft away from the third bevel gear is connected to a limiting plate, and an end of the support rod close to the limiting plate is connected to an electromagnet for magnetically cooperating with the limiting plate to control the rotation of the rotating shaft or limit the rotation of the rotating shaft.

[0008] Optionally, the rotating shaft is connected to the hole wall of the shaft hole through a bearing, and one end of the electromagnet is embedded in the receiving groove of the support rod, and the other end extends out of the receiving groove.

[0009] Optionally, the support rod includes a first section fixedly connected to the second drive shaft and a second section integrally connected to one end of the first section away from the second drive shaft, the second section is perpendicular to the first section, the axial hole is opened in the second section, and the electromagnet is connected to the second section.

[0010] Optionally, the driving member includes a first gear connected to the outer peripheral wall of the first driving shaft and a motor connected to the body, and the output shaft of the motor is connected to a second gear meshing with the first gear.

[0011] The present application also discloses a swimming pool cleaning machine, comprising the driving system of the swimming pool cleaning machine as described above.

[0012] Compared with the prior art, this application has at least the following beneficial effects:

[0013] When the locking member locks the rotation of the third bevel gear, the driving member drives the first driving shaft to rotate, and the rotation of the first driving shaft drives the first bevel gear to rotate. Since the third bevel gear is in a rotation locking state, the first bevel gear is connected to the second bevel gear through the third bevel gear, that is, the rotation of the first bevel gear drives the second bevel gear to rotate in the same direction, so that the first roller and the second roller rotate synchronously, thereby making the body move forward or backward; when the locking member is unlocked and the third bevel gear is in a rotation state, the first bevel gear rotates, the third bevel gear and the first bevel gear are meshed, and the third bevel gear and the second bevel gear are meshed, then the second bevel gear rotates in the opposite direction to the first bevel gear, that is, the rotation directions of the first roller and the second roller are opposite, so that the body can adjust the direction and realize steering. Compared with the swimming pool cleaning machine in the prior art, the present application realizes the rotation of the two rollers on both sides of the body in different ways through one driving member, reduces the number of driving members, and thereby reduces the weight and volume of the swimming pool cleaning machine, as well as reduces the energy consumption of the cleaning machine.

[0020] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] In the description of this application: unless otherwise specified, "plurality" means two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "include", "comprise", "have", etc. also mean "not limited to" (certain units, components, materials, steps, etc.). "Main body" refers to other main structures of the pool cleaning machine, which is prior art and is only partially shown in the schematic diagram.

[0022] refer to Figure 1-3The present application discloses a driving system of a swimming pool cleaning machine, comprising a main body 1, a plurality of driving components 2 connected to the main body 1 and used to drive the main body 1 to move. Figure 1 Only one driving assembly 2 is shown in the figure, and multiple driving assemblies 2 are arranged at intervals along the length direction of the body 1. The driving assembly 2 includes a first driving shaft 21 rotatably connected to one side of the width direction of the body 1 and a second driving shaft 22 rotatably connected to the other side of the width direction of the body 1. One end of the first driving shaft 21 is connected to a first roller 211, and the other end is connected to a first bevel gear 212. One end of the first driving shaft 21 is connected to a second roller 221, and the other end is connected to a second bevel gear 222. A third bevel gear 23 is connected between the first bevel gear 212 and the second bevel gear 222. One side of the third bevel gear 23 is meshed with the first bevel gear 212, and the other side of the third bevel gear 23 is meshed with the second bevel gear 222. The first driving shaft 21 and the second driving shaft 22 are colinear, and the first driving shaft 21 is connected to a driving member 25 for driving the first driving shaft 21 to rotate. The driving assembly 2 also includes a locking member 24 for controlling the self-rotation or self-rotation locking of the third bevel gear 23.

[0023] When the locking member 24 locks the rotation of the third bevel gear 23, the driving member 25 drives the first driving shaft 21 to rotate, and the rotation of the first driving shaft 21 drives the first bevel gear 212 to rotate. Since the third bevel gear 23 is in a rotation locking state, the first bevel gear 212 is connected to the second bevel gear 222 through the third bevel gear 23, that is, the rotation of the first bevel gear 212 drives the second bevel gear 222 to rotate in the same direction, so that the first roller 211 and the second roller 221 rotate synchronously, thereby making the body 1 move forward or backward; when the locking member 24 is unlocked and the third bevel gear 23 is in a rotation state, the first bevel gear 212 is connected to the second bevel gear 222 through the third bevel gear 23. When the wheel 212 rotates, the third bevel gear 23 is meshed with the first bevel gear 212, and the third bevel gear 23 is meshed with the second bevel gear 222. The second bevel gear 222 rotates in the opposite direction to the first bevel gear 212, that is, the first roller 211 and the second roller 221 rotate in opposite directions, so that the main body 1 can adjust the direction and realize steering. Compared with the swimming pool cleaning machine in the prior art, the present application realizes the rotation of the two rollers on both sides of the main body 1 in different modes through a driving member 25, reduces the number of driving members 25, and thus can reduce the weight and volume of the swimming pool cleaning machine, and reduce the energy consumption of the cleaning machine.

[0024] The other components and connection relationships of the swimming pool cleaning machine are prior art and will not be described in detail in this application.

[0025] The locking member 24 includes a support rod 241 connected to the second drive shaft 22 and a rotating shaft 242 connected to the third bevel gear 23. The support rod 241 is provided with an axial hole for passing the rotating shaft 242 at one end away from the second drive shaft 22. The rotating shaft 242 is connected with a limiting plate 243 at one end away from the third bevel gear 23. The support rod 241 is connected with an electromagnet 244 at one end close to the limiting plate 243 for magnetically cooperating with the limiting plate 243 to control the rotation of the rotating shaft 242 or limit the rotation of the rotating shaft 242.

[0026] The support rod 241 rotates synchronously with the second drive shaft 22, and the third bevel gear 23 is rotatably connected to the support rod 241 through the rotating shaft 242, so that the third bevel gear 23 rotates synchronously with the support rod 241 and the second drive shaft 22. When the electromagnet 244 is energized, it generates magnetic force, adsorbs with the limit plate 243, limits the rotation of the rotating shaft 242, and locks the third bevel gear 23 for self-rotation. After power is off, the lock can be released, so that the third bevel gear 23 is in a self-rotation state.

[0027] In some embodiments, the rotating shaft 242 is connected to the hole wall of the shaft hole through a bearing (not shown in the figure), and one end of the electromagnet 244 is embedded in the receiving groove of the support rod 241, and the other end extends out of the receiving groove (not shown in the figure). After the electromagnet 244 is energized, a magnetic force is generated, and the electromagnet 244 extends out of the receiving groove under the adsorption of the magnetic force and adsorbs on the limit plate 243. At this time, one end of the electromagnet 244 is adsorbed on the limit plate 243, and the other end is in the receiving groove, realizing the limitation of the rotation of the limit plate 243.

[0028] The support rod 241 includes a first section 2411 fixedly connected to the second drive shaft 22 and a second section 2412 integrally connected to one end of the first section 2411 away from the second drive shaft 22, the second section 2412 is perpendicular to the first section 2411, the shaft hole is opened in the second section 2412, and the electromagnet 244 is connected to the second section 2412. The first section 2411 and the second section 2412 form an "L" shape to avoid the third bevel gear 23 and the second bevel gear 222.

[0029] The driving member 25 includes a first gear 251 connected to the outer peripheral wall of the first driving shaft 21 and a motor 252 connected to the body 1 . The output shaft of the motor 252 is connected to a second gear 253 meshing with the first gear 251 .

[0030] The present application also discloses a swimming pool cleaning machine, comprising the driving system of the swimming pool cleaning machine as described above.

[0031] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0032] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
