Description

Technical Field

[0001] The utility model relates to the technical field of swimming pool cleaning, in particular to a walking structure of a swimming pool cleaning robot. Background Art

[0002] Swimming is a very good way of fitness exercise and is sought after by young people. For this reason, more and more swimming pools have been built. However, since the water storage capacity in the swimming pool is relatively large, the cost of replacing it frequently is too high. Therefore, people often use sedimentation to deal with impurities. This method causes impurities to form sediments and accumulate at the bottom of the swimming pool. Subsequently, the sediments at the bottom of the swimming pool need to be cleaned up manually or by machines. For this reason, swimming pool cleaning robots have been created. Traditional swimming pool cleaning robots greatly save labor costs. The debris and sediments where they pass are well cleaned up, and the swimming pool cleaning robots can perform continuous operations in the swimming pool.

[0003] In this regard, the Chinese patent announcement number is CN219974023U, which discloses a swimming pool robot that can automatically switch directions based on a Hall sensor, including a robot upper half assembly, a robot lower half assembly and a wheel assembly; the wheel assembly includes a wheel body, and the wheel body is connected to the robot lower half assembly through a fixing member; the inner side of the wheel body is also provided with multiple groups of magnets, and the multiple groups of magnets are distributed on the circular edge with the center of the circle as A. By providing a Hall sensor and a magnet, the magnet surrounds the outer side of the Hall sensor. When the magnet rotates around the Hall sensor, a pulse signal is generated between the magnet and the Hall sensor, and the pulse signal is received by the controller. When the swimming pool robot is blocked by steps or other obstacles, the magnet cannot rotate, the pulse signal disappears, and the controller cannot receive the pulse signal. At this time, the controller controls the swimming pool robot to turn around, which facilitates the normal operation of the robot at the bottom of the swimming pool. It can be seen that the above-mentioned Hall sensor and multiple groups of magnets are arranged on the axle. However, the wheels of the swimming pool robot need to be disassembled and replaced during use. For example, if hair or other debris is stuck on the axle, the above patent will also disassemble the sensor and magnet when replacing the wheel when encountering this situation. There are many parts to disassemble, which is troublesome and reassembly is also troublesome.

[0004] Based on this, the applicant proposed a walking structure of a swimming pool cleaning robot to solve the above technical problems. Utility Model Content

The above arrangement ensures that the wheel can be installed and assembled normally, and ensures the normal walking of the swimming pool cleaning robot.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] The utility model provides a walking structure of a swimming pool cleaning robot. Figure 1-8 As shown, it includes a main shell 1, a wheel 2, and the wheel 2 is rotatably connected to the main shell 1 through an axle 15, and also includes: a coupling cylinder 3, the coupling cylinder 3 is coaxially connected to the axle 15 and plug-fitted; a magnet group is arranged at an end of the coupling cylinder 3 away from the axle 15 and located in the main shell 1; wherein, when the coupling cylinder 3 is disengaged from the axle 15, the wheel 2 and the axle 15 are removed from the main shell 1; a sensor 14 is arranged in the main shell 1 near the wheel 2 and detects the rotation of the wheel 2.

[0037] The main housing 1 is detachably connected with a base and an upper shell.

[0038] The main housing 1 in the utility model is the appearance of a conventional swimming pool cleaning robot in the prior art. For details, please refer to the Chinese patent announcement number CN219974023U, which is a swimming pool robot that can automatically switch directions based on a Hall sensor 14. It generally uses four wheels 2, one wheel 2 is installed at the front and one wheel 2 is installed at the center of the front, and the two wheels 2 in the middle are installed at the rear and connected by an axle 15. The placement position of the sensor 14 is set at the two wheels 2 in the middle. The sensor 14 can preferably be a Hall sensor 14, which can generate a pulse signal between the Hall sensor 14 and the magnet 13, and the pulse signal is received by the controller in the main housing 1, so as to achieve certain effects, such as judging whether the swimming pool robot is blocked by an obstacle by the pulse signal.

[0039] In order to facilitate the disassembly of the axle 15, the utility model plugs the axle 15 into the coupling cylinder 3. The wheel 2 can be replaced by removing the axle 15 from the coupling cylinder 3, and the sensor 14 and the magnet group 13 are both arranged in the main shell 1. Since the magnet group 13 is coaxial with the wheel 2, it does not affect the detection data of the sensor 14.

[0040] Further optimized, the main shell 1 includes: an upper shell 101; a lower shell 102, the lower shell 102 includes a receiving chamber 16, and the receiving chamber 16 is arranged close to the axle 15; the lower shell 102 is also covered with a filter screen 17.

[0041] The main housing 1 is divided into an upper housing 101 and a lower housing 102 which are detachable from top to bottom. The lower housing 102 includes a receiving chamber 16, which can be used to provide installation space for core components of the swimming pool robot. In addition to the receiving chamber 16, a filter 17 is provided outside the receiving chamber 16 to filter impurities. Figure 2 , 3 As shown, the lower shell 102 is divided into three parts, the front part and the rear part, and the accommodating chamber 16 arranged in the middle, wherein the front part and the rear part are used to place the components of the swimming pool robot for absorbing and draining water. The accommodating chamber 16 is a chamber formed by the front part and the rear part, which is used to accommodate the control housing seat 18.

[0042] For further optimization, a fully sealed control housing seat 18 is provided in the accommodating cavity 16 , the sensor 14 is installed at a position of the control housing seat 18 close to the wheel 2 , and the magnet group extends into the accommodating cavity 16 and is arranged opposite to the sensor 14 .

[0043] like Figure 3 As shown, most of the space of the accommodating cavity 16 is used to place the control housing seat 18, and a very small part of the space is used to ensure that the magnet group extends into the accommodating cavity 16 to ensure that the sensor 14 and the magnet group are arranged relative to each other for detection.

[0044] The sealing setting of the control housing seat 18 ensures that the electronic components in the control housing seat 18 will not be affected by external water, and the sensor 14 is arranged in the control housing seat 18 to ensure that the circuit board of the sensor 14 is not exposed to the water, eliminating the gluing and sealing process in the prior art, greatly improving production efficiency and reducing the risk of water leakage.

[0045] Further optimization also includes: a wheel bracket 5, one end of which is fixedly arranged on the outside of the main shell 1; there are two wheel brackets 5, and a space for accommodating the wheel 2 is formed between the two wheel brackets 5; a through hole is arranged on the wheel bracket 5 and penetrated by the axle 15.

[0046] The wheel support 5 is a vertical frame 501, which is an ear plate, such as Figure 4As shown, there are two wheel brackets 5, which are fixedly connected to the upper plate 502. The upper plate 502 can be connected to the main housing 1 in a detachable connection manner. A mounting member 503 is provided on the upper plate 502. The top of the mounting member 503 is provided with a stepped platform with a smaller diameter. A snap-on plate 6 is provided in the main housing 1. The snap-on plate 6 cooperates with the top of the mounting member 503 to achieve the rapid installation of the wheel bracket 2. In addition, a through hole is provided on the ear plate for the axle 15 to pass through. The size of the through hole is adapted to the axle 15. One end of the axle 15 also includes a stopper 7. The stopper 7 is abutted against the surface of the ear plate to achieve the purpose of installing the axle 15. The wheel 2 is installed on the axle 15 so that the swimming pool cleaning robot moves under the action of the wheel 2. The above arrangement ensures that the wheel 2 can be installed and assembled normally, and ensures the normal walking of the swimming pool cleaning robot.

[0047] Further optimized, the axle 15 includes a joint portion 8 protruding at one end, and a clamping portion 9 cooperating with the joint portion 8 is provided in the coupling cylinder 3. After the joint portion 8 cooperates with the clamping portion 9, the coupling cylinder 3 is coaxially connected to the axle 15.

[0048] In order to ensure that the axle 15 and the coupling cylinder 3 can be smoothly plugged in, a joint portion 8 is provided at one end of the axle 15, and a corresponding clamping portion 9 is provided in the coupling cylinder 3. The joint portion 8 cooperates with the clamping portion 9 to achieve a coaxial connection between the coupling cylinder 3 and the axle 15.

[0049] Further optimized, the joint portion 8 includes a joint 801 arranged at one end of the axle 15, a gap is provided between the axle 15 and the joint 801, the engaging portion 9 includes a protrusion 901 extending along the side wall of the coupling cylinder 3, and the gap cooperates with the protrusion 901 to realize the cooperation between the axle 15 and the coupling cylinder 3.

[0050] like Figure 4 As described, a stepped shaft 10 is formed at one end of the axle 15, and the stepped shaft 10 is connected to the joint 801, and the diameter of the stepped shaft 10 is much smaller than the diameter of the joint 801, so that a gap is formed between the axle 15 and the joint 801, and the protrusion 901 enters into the gap to achieve the cooperation between the axle 15 and the coupling cylinder 3.

[0051] Further optimized, the joint 801 includes a cutting plane 802, and a plane block matching with the cutting plane 802 is arranged in the coupling cylinder 3. When the cutting plane 802 is in contact with the plane block, the axle 15 and the coupling cylinder 3 are matched and plugged.

[0052] By setting the cutting plane 802 so that the cutting plane 802 and the plane block on the inner wall of the coupling cylinder 3 fit together, the axle 15 is not a perfect cylinder, but a cylinder with a small part cut off, which makes disassembly more convenient.

[0053] In a further optimization, a plurality of grooves 11 are radially arranged at one end of the coupling cylinder 3 close to the axle 15 .

[0054] The provision of the groove 11 allows the worker to reach into the inner wall of the coupling cylinder 3 with an external tool to touch the protrusion 901 on the inner wall of the coupling cylinder 3 during disassembly, thereby achieving the purpose of rapid disassembly.

[0055] Further optimized, one end of the coupling cylinder 3 away from the axle 15 is connected to the rotating disk 12, and the magnet 13 group includes magnets 13 embedded along the circumference of the rotating disk 12.

[0056] The magnet 13 originally installed on the axle 15 in the prior art is installed on the rotating disk 12 through the coaxially connected coupling cylinder 3. Since the rotating disk 12 is coaxially arranged, the rotation speed of the rotating disk 12 is consistent with the rotation speed of the wheel 2. Under the premise of not affecting the measurement of the sensor 14, it provides convenience for the disassembly of the coupling cylinder 3 and the axle 15.

[0057] In further optimization, the projection of the sensor 14 along a direction perpendicular to the forward direction of the wheel 2 is located on the circular surface of the wheel 2 .

[0058] In this way, the sensor 14 can detect the number of rotations and the rotation speed of the wheel 2 through the magnet 13, and then feedback to the control system in the main housing 1 to realize the corresponding function drive. For example, the control system in patent announcement numbers CN217735012U, CN219974023U, and CN219387382U can be referred to to realize the corresponding function.

[0059] Further optimization is performed, the diameter of the coupling cylinder 3 is larger than the diameter of the axle 15 , and the coupling cylinder 3 is hollow so as to be plugged in with the axle 15 .

[0060] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
