DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, rear...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0033] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element present at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intermediate element present at the same time.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0035] The present utility model provides a water surface cleaning robot. Referring to Figures 1-3 , it includes:

[0036] A robot main body for cleaning the garbage on the water surface;

[0037] An anti-collision component, and the anti-collision component at least has a lateral part protruding from the robot main body;

[0038] An elastic connection assembly, which is connected between the anti-collision component and the robot main body so that the anti-collision component can telescopically move relative to the robot main body.

[0039] Among them, the robot main body generally includes structures such as a rotary brush, a driving mechanism, a collection tank, etc. to collect sundries and garbage on the water surface and complete the cleaning of the water surface. The anti-collision component can be a component with strong elasticity such as a rubber ball or a spring, so that when hitting an obstacle, the anti-collision component itself also has a certain role in reducing the impact; it can also be a rigid material such as metal or alloy to protect the robot main body from being hit. As an assembly disposed between the anti-collision component and the robot main body, the elastic connection assembly can achieve the telescoping of the anti-collision component through its own elasticity. For example, foam materials, rubber, sponge, etc. are used as the elastic connection assembly, or it can also be achieved through a more complex structural combination, such as a nested telescopic rod, the combination of a spring and a buckle, etc. This embodiment does not limit this. It can be understood that the anti-collision component can be welded, thread-connected, snap-connected or adhesively connected to the elastic connection assembly, and only needs to ensure that the anti-collision component will not easily fall off from the elastic connection assembly. The connection method between the elastic connection assembly and the robot main body is similar, and will not be elaborated here.

[0040] Specifically, when the robot body is cleaning the water surface and hits an obstacle, first, the anti-collision component is impacted. Subsequently, the elastic connection component connected to it drives the anti-collision component to contract under the action of the impact force to protect the robot body from damage. When the robot body moves away from the obstacle, the elastic connection component resets under the action of internal force or other driving devices, so that the anti-collision component continues to protrude outside the robot body to prevent the next collision.

[0041] In the present utility model, an elastic connection component and an anti-collision component connected to the elastic connection component are provided on the robot body of the water surface cleaning robot. By relying on the expansion and contraction of the anti-collision component and the elastic connection component, the impact force when the water surface cleaning robot hits an obstacle will not directly act on the robot body, and can be slowly released, reducing the probability of damage to the robot body and improving the service life of the water surface cleaning robot.

[0042] Such as Figure 3 and Figure 4 As shown in, in some embodiments, the elastic connection component includes:

[0043] A connecting arm having a first end and a second end disposed opposite to each other. The first end is rotatably connected to the robot body, and the second end is connected to the anti-collision component;

[0044] An elastic member, one end of the elastic member is connected to the robot body, the other end of the elastic member is connected to the connecting arm, and the part where the elastic member is connected to the connecting arm is located between the first end and the second end.

[0045] The connecting arm can be rotatably connected to the robot body through structures such as pins, bearings, hinges, hinges, etc., and the elastic member can be connected to the connecting arm and the robot body by welding, clamping, bonding, etc. The elastic member is a component that can be stretched and contracted, such as rubber, silica gel, bellows, etc.

[0046] During the specific use process, if the collision component hits an obstacle, the generated impact force will cause the connecting arm to rotate relative to the robot body and pull the elastic member arranged between the connecting arm and the robot body, thereby realizing the slow release of the impact force and avoiding damage to the robot body. And the deflected connecting arm drives the collision component to deflect as well, which can further minimize the subsequent impact with the obstacle, and at the same time guide the robot body to another movement direction to avoid the obstacle and improve the cleaning efficiency.

[0047] Such as Figure 4As shown, in some embodiments, the robot body is configured with a receiving groove having an opening at one end. At least a part of the connecting arm is received in the receiving groove, and the first end is rotatably mounted in the receiving groove. The elastic member is elastically connected between the inner side wall of the receiving groove and the side wall of the connecting arm;

[0048] At least a part of the anti-collision member can be telescoped in the receiving groove.

[0049] The receiving groove is used to protect the elastic member, the connecting arm, and the connection structure between the receiving groove and the connecting arm, preventing them from being easily damaged by the external environment. At the same time, the receiving groove also has the function of restricting the rotation stroke of the connecting arm. When the connecting arm rotates to a certain angle, the connecting arm abuts against the edge of the opening of the receiving groove and cannot rotate further, avoiding overstretching the elastic member and causing irreparable damage to the elastic member. It can be understood that the receiving groove should also have a certain width to provide enough space for the connecting arm to rotate. The setting of the width can be determined according to the size of the water surface cleaning robot and the types of possible obstacles. This embodiment does not limit this.

[0050] The elastic member connects the inner side wall of the receiving groove and the side wall of the connecting arm, thereby providing elastic force to buffer the impact force when the connecting arm rotates. The positions of both ends of the elastic member can be determined according to the material of the elastic member itself and the magnitude of the elastic force required. For example, when the acute angle formed between the elastic member and the connecting arm is small, the deformation amount of the elastic member during the rotation of the connecting arm is also small. At this time, the pulling force provided by the elastic member is also small, which is suitable for the situation where the elastic member cannot be overly stretched.

[0051] It can be understood that if the connecting arm is made of an elastic material, it itself also has a certain degree of scalability. The rotation of the connecting arm will also cause the anti-collision member to contract towards the direction of the robot body. Therefore, at least a part of the anti-collision member can enter the receiving groove. When hitting an obstacle, the telescopic range of the anti-collision member is larger, the buffering effect is better, and it can also prevent the anti-collision member from colliding with the opening of the receiving groove.

[0052] As Figure 4 shown, in some embodiments, a connecting shaft is provided in the receiving groove, a connecting hole is provided at the first end, and the first end is rotatably connected to the connecting shaft through the connecting hole.

[0053] The first end of the connecting arm is sleeved on the connecting shaft in the receiving groove through the connecting hole to achieve rotational connection. Since there is a certain gap between the connecting hole and the connecting shaft, the connecting arm can rotate freely around the connecting shaft. The rotation range of the connecting arm is determined by actual needs. If it is necessary to control the rotation angle of the connecting arm, a part of the connecting shaft can be set as a groove, and a convexity with a smaller size is provided at the position corresponding to the groove in the connecting hole, so that the convexity can only rotate in the groove, thereby achieving the function of restricting the connecting arm.

[0054] In this embodiment, through the cooperation between the connecting hole and the connecting shaft, the rotational connection between the connecting arm and the receiving groove is realized, with stable connection, simple structure, easy manufacturing and installation, reducing production costs and maintenance difficulties.

[0055] As Figure 4 shown, in some embodiments, the receiving groove has a first groove side wall and a second groove side wall that are oppositely spaced apart, and the elastic member is connected between the connecting arm and the first groove side wall;

[0056] When the anti-collision component is stressed and the robot body shrinks, the connecting arm swings towards the second groove side wall;

[0057] When the stress on the anti-collision component is removed, the connecting arm swings towards the first groove side wall under the action of the elastic member;

[0058] The first groove side wall is provided with a limiting member, and the connecting arm is correspondingly provided with a limiting groove for the limiting member to cooperate with to limit the stroke of the elastic member pulling the connecting arm to swing towards the first groove side wall.

[0059] Since when hitting an obstacle, the connecting arm will swing left and right under the action of the impact force and the elastic force of the elastic member, in order to prevent the connecting arm from hitting the receiving groove during the reset process, a limiting member is provided in the receiving groove, and a limiting groove is provided at the position of the connecting arm corresponding to the limiting member, so that after the connecting arm swings to a certain position, the limiting member abuts in the limiting groove, thereby restricting the connecting arm from continuing to swing and avoiding damage to the receiving groove caused by impact.

[0060] As Figure 3 and Figure 4 shown, in some embodiments, the connecting arm extends from the first end to the second end in a curved manner; and / or,

[0061] The connecting arm is made of at least one of polyamide, carbon fiber, rubber, and silicone.

[0062] Making the connecting arm present a certain curvature can absorb more energy through the bending and deformation of the connecting arm itself during the collision process, reducing the impact force transmitted to other components, thereby protecting the connecting arm itself and other components. The connecting arm can be made of polyamide, carbon fiber, rubber, or silicone, with good elasticity and can extend the service life of the connecting arm.

[0063] As Figure 4 shown, in some embodiments, the elastic member is a spring. It has a low cost and is easy to install. Exemplarily, hook locking parts are provided at both ends of the spring, and interfaces that can be latched with the hook locking parts are provided in the connecting arm and the receiving groove, so that the spring can be installed between the two, which is very convenient to use.

[0064] As shown Figures 1-4 In some embodiments, the anti-collision component is a roller or a bearing rotatably connected to one end of the elastic connection component. During the impact, the roller or the bearing rolls on the contact surface instead of sliding, thus greatly reducing the frictional force, reducing the wear between the contact surfaces, and at the same time, the impact force can be absorbed and dispersed through rolling and rotation, reducing the direct impact of the collision on the component and improving the protection effect.

[0065] As shown Figure 1 In some embodiments, the robot body is divided into a front end and a rear end along the forward direction, and at least part of the anti-collision component protrudes from the front end of the robot body. Since the water surface cleaning robot usually moves forward at a faster speed and the impact force when hitting an obstacle is also greater, the anti-collision component is arranged at the front end of the robot body so that the anti-collision component can give full play to its role.

[0066] As shown Figure 1 In some embodiments, there are at least two of the anti-collision components and the elastic connection components respectively. At least one anti-collision component and one elastic connection component are arranged on each side of the water surface cleaning robot in the forward direction. An anti-collision component and an elastic connection component are arranged on both sides of the robot body, so that both the left and right sides of the robot body can be protected, reducing the probability of damage to the robot body.

[0067] The above are only partial or preferred embodiments of the present utility model. Whether in terms of words or drawings, the scope of protection of the present utility model cannot be limited thereby. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the concept of a whole of the present utility model, or any direct / indirect application in other related technical fields is included in the scope of protection of the present utility model.
