Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0038] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0039] Swimming pool vacuum cleaner is a kind of equipment used to clean the bottom and walls of swimming pools. Its steering is generally achieved through universal wheels. It should be noted that universal wheels have obvious advantages in large-angle steering and turning in circles. However, when the steering angle is very small and the steering angle needs to be controlled, the universal wheels cannot meet the requirements and cannot effectively control the steering angle.
[0040] In view of this, the utility model provides a steering mechanism, which includes a bottom shell 100 and a wheel assembly 200, wherein the wheel assembly 200 includes an eccentric wheel 210 and a wheel bracket 220; the eccentric wheel 210 and the wheel bracket 220 are rotatably matched; the wheel bracket 220 includes a rotating shaft 223, the rotating shaft 223 is arranged on the bottom shell 100, and can rotate around its own axis, and its axis extends along the radial direction of the eccentric wheel 210 and is perpendicular to the travel direction of the eccentric wheel 210; in the wheel bracket 220 and the bottom shell 100, one of the two is provided with a sliding groove 110, the sliding groove 110 extends around the axis of the rotating shaft 223, and the other is provided with a limit bolt 221, the limit bolt 221 is inserted into the sliding groove 110, and can slide from one end of the sliding groove 110 to the other end under steering conditions.
[0041] In the steering mechanism, the eccentric wheel 210 is rotatably connected to the wheel bracket 220, and the rotating shaft 223 of the wheel bracket 220 is rotatably connected to the bottom shell 100, and the axis of the rotating shaft 223 extends along the radial direction of the eccentric wheel 210 and is perpendicular to the traveling direction of the eccentric wheel 210. In this way, when the eccentric wheel 210 turns, the wheel bracket 220 is driven to rotate synchronously around the axis of the rotating shaft 223; in addition, since the wheel bracket 220 and the bottom shell 100 are respectively provided with a sliding groove 110 and a limiting bolt 221 that are plugged into each other, and the sliding groove 110 extends around the axis of the rotating shaft 223, when the wheel bracket 220 rotates, the limiting bolt 221 will rotate relative to the sliding groove 110 around the axis of the rotating shaft 223, and the rotation range depends on the length of the sliding groove 110, that is, the steering angle of the eccentric wheel 210 depends on the length of the sliding groove 110.
[0042] It can be seen that compared with the prior art, the steering mechanism realizes the control of the steering angle of the eccentric wheel 210 by separately providing the sliding groove 110 and the limit bolt 221 on the wheel bracket 220 and the bottom shell 100, and the length of the sliding groove 110 corresponds to the maximum steering angle, so that the wheel can achieve a small angle of steering.
[0043] The following combination Figures 1 to 5 The structure and shape of the steering mechanism provided in this embodiment are described in detail:
[0044] In one embodiment of the present application, reference Figure 5 The wheel bracket 220 includes a mounting seat 222 , and a top surface of the mounting seat 222 protrudes to form a limited position bolt 221 ; the eccentric wheel 210 is rotatably connected to the mounting seat 222 through a wheel shaft 230 .
[0045] Continue to refer Figure 5 , the rotating shaft 223 is vertically connected to the top surface of the mounting seat 222, and the limiting bolt 221 is spaced apart from the rotating shaft 223; Figures 1 to 4The sliding groove 110 is disposed on the bottom shell 100 , and the limiting bolt 221 passes through the sliding groove 110 .
[0046] by Figure 1 For example, when the eccentric wheel 210 turns, the rotating shaft 223 is driven to rotate, and the stop bolt 221 slides along the length direction of the sliding groove 110. Here, the sliding distance of the stop bolt 221 corresponds to the steering angle of the eccentric wheel 210, and the steering angle range of the eccentric wheel 210 can be controlled by designing the length of the sliding groove 110.
[0047] Preferably, reference Figures 1 to 4 The sliding groove 110 is arc-shaped; the stopper bolt 221 is matched with the sliding groove 110 and extends around the rotation axis of the wheel bracket 220. Such a design prevents the stopper bolt 221 from being separated from its sliding track when the eccentric wheel 210 vibrates, thereby ensuring smooth steering and steering stability.
[0048] For further information, please refer to Figures 1 to 4 A limiting groove 120 is also provided on the bottom shell 100, and the limiting groove 120 is used to be plugged and matched with the limiting bolt 221 to limit the rotation of the limiting bolt 221; in the moving direction of the bottom shell 100, the limiting groove 120 and the sliding groove 110 are respectively arranged on both sides of the rotation axis of the wheel bracket 220, and either of them is plugged and matched with the limiting bolt 221.
[0049] Specifically, the limiting groove 120 is matched with the limiting bolt 221. When the limiting bolt 221 is inserted into the limiting groove 120, the wheel bracket 220 cannot rotate. Figures 2 to 4 As shown, at the left and right ends of the bottom shell 100, namely the rear end and the front end, the limiting groove 120 and the sliding groove 110 are matched with each other; wherein, at the front end, an A-type sliding groove 110 and a limiting groove 120, or a B-type sliding groove 110 and a limiting groove 120 are arranged, and similarly, an A-type sliding groove 110 and a limiting groove 120, or a B-type sliding groove 110 and a limiting groove 120 are also arranged at the rear end, and here, the curvature of the A-type sliding groove 110 and the B-type sliding groove 110 are different.
[0050] When used, the limiting bolt 221 on the wheel bracket 220 at the front end is inserted into the A-type sliding groove 110, and the limiting bolt 221 on the wheel bracket 220 at the rear end is inserted into the limiting groove 120, or the limiting bolt 221 on the wheel bracket 220 at the front end is inserted into the B-type sliding groove 110, and the limiting bolt 221 on the wheel bracket 220 at the rear end is inserted into the limiting groove 120, or the limiting bolt 221 on the wheel bracket 220 at the front end is inserted into the A-type sliding groove 110, and the limiting bolt 221 on the wheel bracket 220 at the rear end is inserted into the B-type sliding groove 110. In this way, different combinations are formed to achieve control of different steering angles.

In order to prevent the wheel bracket 220 from being separated from the bottom shell 100, refer to Figure 1 and Figure 5 The rotating shaft 223 is provided with a groove 2231 extending around the circumference thereof; the bottom shell 100 is provided with a limiting member, which is plugged into and matched with the groove 2231.
[0052] In one embodiment of the present application, reference Figure 5 The limiter includes an elastic buckle 130, which has a tendency to move in a direction perpendicular to the axis of the rotating shaft 223 and toward the rotating shaft 223. Specifically, the elastic buckle 130 is engaged with the groove 2231 to prevent the rotating shaft 223 from being separated from the mounting hole; furthermore, the elastic buckle 130 can rotate relative to the rotating shaft 223 along the groove 2231, ensuring smooth steering.
[0053] In other embodiments, the limiting member includes a bolt, which is threadedly connected to the bottom shell 100. The bolt can be screwed into or out of the groove 2231 by rotation, thereby facilitating the installation of the wheel bracket 220; similarly, when the bolt is inserted into the groove 2231, it can also rotate relative to the rotating shaft 223 to ensure smooth steering.
[0054] For further reference, Figure 1 and Figure 5 The eccentric wheel 210 includes a wheel body 211, which is cylindrical; a flange 212 is formed on the side of the wheel body 211 around the circumference of the wheel body 211, and the flange 212 is close to one end surface of the wheel body 211. With such a design, the force point of the eccentric wheel 210 deviates from the axis of the rotating shaft 223, so that the steering mechanism can control the rotation direction on the basis of controlling the steering angle.

[0056] In the steering mechanism, the eccentric wheel 210 is designed to be easy to steer; the cooperation of the sliding groove 110 and the limit bolt 221 realizes the control of the steering angle of the eccentric wheel 210, and the length of the sliding groove 110 corresponds to the maximum steering angle, so that the wheel can achieve a small angle of steering.
[0057] The present embodiment further provides a swimming pool vacuum cleaner, including a steering mechanism.
