Description

Technical Field

[0001] This utility model relates to the field of sweeping robot technology, and in particular to a collision buffer structure for an intelligent sweeping robot. Background Technology

[0002] A smart robotic vacuum cleaner is an automated cleaning device that typically uses built-in sensors, artificial intelligence technology, and a navigation system to perform functions such as sweeping, vacuuming, and mopping. It can autonomously adjust its cleaning route according to changes in the environment and can be operated through programming or remote control.

[0003] A search revealed a Chinese patent, CN206576823U, which discloses a collision buffer structure for an intelligent robotic vacuum cleaner. This structure includes a fixed shell and a protective plate. A plurality of first elastic plates and a plurality of second elastic plates are fixed side-by-side between one surface of the fixed shell and one surface of the protective plate. The included angle between the first and second elastic plates is in the range of 1°-45°. A shock-absorbing layer is also fixed to one surface of the protective plate. This invention, by fixing this collision buffer structure around the periphery of the robotic vacuum cleaner, allows the robot to make certain collision contacts, thus enabling it to reach and clean surfaces without missing any areas. Furthermore, the collision buffer structure prevents damage to the robot after an impact, thereby extending its service life.

[0004] In existing technologies, when a smart robotic vacuum cleaner is working, it may still encounter other objects, which reduces the lifespan of the robot. Therefore, a collision buffer structure for smart robotic vacuum cleaners is needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the lifespan of a robotic vacuum cleaner is reduced when it encounters other objects during use, and to propose an intelligent collision buffer structure for robotic vacuum cleaners.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a collision buffer structure for an intelligent sweeping robot, comprising a first buffer mechanism, wherein two second buffer mechanisms are fixedly installed on the outer wall of the first buffer mechanism.

[0007] The first buffer mechanism includes a robot vacuum cleaner body. Four shock-absorbing springs are fixedly installed on the outer wall of the robot vacuum cleaner body. Four shock-absorbing dampers are fixedly installed on the outer wall of the robot vacuum cleaner body. The outer walls of the four shock-absorbing dampers are all connected to the interior of the four shock-absorbing springs. Two anti-collision plates are fixedly installed on one side of the outer wall of the four shock-absorbing springs. The outer walls of the two anti-collision plates are fixedly connected to the opposite side of the outer walls of the four shock-absorbing dampers. Three buffer shafts are fixedly installed on one side of the outer wall of each of the two anti-collision plates. Six buffer holes are opened on the outer wall of the robot vacuum cleaner body. The outer walls of the six buffer shafts are movably inserted into the interior of the six buffer holes.

[0008] Preferably, the outer wall of the robot vacuum cleaner body has four strip grooves, and two strip plates are fixedly installed on one side of the outer wall of each of the two anti-collision plates, and the outer walls of the four strip plates are movably inserted into the four strip grooves.

[0009] Preferably, four arc-shaped anti-collision pads are fixedly installed on the outer wall of the robot body.

[0010] Preferably, the second buffer mechanism includes a rectangular plate, and two side sleeves are fixedly installed on the outer wall of the rectangular plate.

[0011] Preferably, a strip-shaped hole is provided on one side of the outer wall of each of the two side sleeves, and a positioning block is movably inserted into the inner surface wall of each of the two strip-shaped holes.

[0012] Preferably, a rectangular anti-collision pad is fixedly installed on one side of the outer wall of the rectangular plate, and bolts are threadedly connected to one side of the outer wall of the two positioning blocks, and locking blocks are movably sleeved on the outer wall of the two bolts.

[0013] Preferably, one side of the outer wall of each of the four positioning blocks is fixedly connected to the outer wall of the robot body, and one side of the outer wall of each of the two rectangular plates is in contact with the outer wall of the robot body.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, when the intelligent sweeping robot collides, the four shock-absorbing springs and four shock-absorbing dampers, along with the movement of six buffer shafts within six buffer holes and four strip plates within four strip grooves, provide a shock-absorbing and buffering effect, thereby improving the service life of the intelligent sweeping robot.

[0016] In this invention, the two rectangular anti-collision pads and four arc-shaped anti-collision pads on the side can still provide a collision buffering effect for the intelligent sweeping robot. Furthermore, the two rectangular anti-collision pads are easy to disassemble and replace through the four positioning blocks, side sleeve blocks, four strip holes, four bolts, and four locking blocks, thus improving the subsequent collision buffering effect of the intelligent sweeping robot.

[0024] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: As Figures 1-4As shown, this utility model provides a collision buffer structure for an intelligent sweeping robot, including a first buffer mechanism 1, and two second buffer mechanisms 2 are fixedly installed on the outer wall of the first buffer mechanism 1.

[0027] The first buffer mechanism 1 includes a robot vacuum cleaner body 101. Four shock-absorbing springs 102 are fixedly installed on the outer wall of the robot vacuum cleaner body 101. Four shock-absorbing dampers 103 are fixedly installed on the outer wall of the robot vacuum cleaner body 101, and the outer walls of the four shock-absorbing dampers 103 are all connected to the interior of the four shock-absorbing springs 102. Two anti-collision plates 104 are fixedly installed on one side of the outer wall of the four shock-absorbing springs 102, and one side of the outer wall of the two anti-collision plates 104 is fixedly connected to the opposite side of the outer wall of the four shock-absorbing dampers 103. Three buffer shafts 105 are fixedly installed on each side. The outer wall of the robot body 101 has six buffer holes 106, and the outer walls of the six buffer shafts 105 are movably inserted into the six buffer holes 106. The outer wall of the robot body 101 has four strip grooves 107. Two strip plates 108 are fixedly installed on one side of the outer wall of the two anti-collision plates 104, and the outer walls of the four strip plates 108 are movably inserted into the four strip grooves 107. Four arc-shaped anti-collision pads 109 are fixedly installed on the outer wall of the robot body 101.

[0028] The overall effect of Embodiment 1 is that when the sweeping robot collides with other objects, the two anti-collision plates 104 will come into contact with the objects. Since two shock-absorbing springs 102 and two shock-absorbing dampers 103 are installed between the two anti-collision plates 104 and the sweeping robot, and three buffer holes 106 and two strip grooves 107 are opened on both sides of the sweeping robot, and the three buffer shafts 105 installed on one side of the outer wall of the two anti-collision plates 104 are movably inserted into the six buffer holes 106, and the two strip plates 108 installed on one side of the outer wall of the two anti-collision plates 104 are movably inserted into the four strip grooves 107, the force of the collision between the two anti-collision plates 104 and the objects can be offset, and a collision buffering effect is achieved, thereby improving the service life of the intelligent sweeping robot.

[0029] Example 2: As Figures 2-4As shown, the second buffer mechanism 2 includes a rectangular plate 201. Two side sleeves 202 are fixedly installed on the outer wall of the rectangular plate 201. A strip hole 203 is opened on one side of the outer wall of each of the two side sleeves 202. A positioning block 204 is movably inserted into the inner wall of each of the two strip holes 203. A rectangular anti-collision pad 205 is fixedly installed on one side of the outer wall of the rectangular plate 201. Bolts 206 are threadedly connected to one side of the outer wall of each of the two positioning blocks 204. Locking blocks 207 are movably sleeved on the outer wall of each of the two bolts 206. One side of the outer wall of each of the four positioning blocks 204 is fixedly connected to the outer wall of the robot body 101. One side of the outer wall of each of the two rectangular plates 201 is in contact with the outer wall of the robot body 101.

[0030] The overall effect of Embodiment 2 is that the arc-shaped anti-collision pads 109 installed at the four corners of the robot vacuum body 101 further improve the anti-collision and buffering effect. Secondly, two positioning blocks 204 are installed on both sides of the robot vacuum body 101. The two rectangular plates 201 are fitted onto the four positioning blocks 204 through the strip holes 203 opened on the four side sleeve blocks 202. Then, under the action of four bolts 206 and four locking blocks 207, the bolts 206 are threaded into the inside of the positioning blocks 204, and at the same time, the four locking blocks 207 are locked between the nuts on the four positioning blocks 204 and the four bolts 206. Thus, the installation of the two rectangular plates 201 and the two rectangular anti-collision pads 205 with the robot vacuum is completed, and it is easy to disassemble and replace, further improving the subsequent anti-collision and buffering effect of the robot vacuum.

[0031] Working principle: First, when the anti-collision plates 104 on both sides of the sweeping robot are impacted, the four strip plates 108 move within the four strip grooves 107, the six buffer shafts 105 move within the six buffer holes 106, and the four shock-absorbing springs 102 and four shock-absorbing dampers 103 installed between the two anti-collision plates 104 and the sweeping robot effectively offset the impact force received from the outside, achieving an anti-collision buffering effect. Secondly, the four arc-shaped anti-collision pads 109 and the two rectangular anti-collision pads 205 provide anti-collision and shock-absorbing buffering for other directions of the sweeping robot. The two rectangular anti-collision pads 205 and the two rectangular plates 201 are fitted onto the four positioning blocks 204 through the four side sleeves 202 and the four strip holes 203, and then installed by the four bolts 206 and the four locking blocks 207. The installation is convenient and easy to disassemble and replace, improving the subsequent anti-collision buffering effect. In general, the first buffering mechanism 1 and the second buffering mechanism 2 improve the service life of the intelligent sweeping robot.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
