Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision floor sweeping robots, and particularly to an anti-collision floor sweeping robot. Background Art

[0002] In order to increase the suction force of the robot and the volume of the dust collection box, the size of the whole robot needs to be increased for traditional floor sweeping robots. Either the vertical dimension of the robot is increased, or the horizontal dimension of the robot is increased. The disadvantage of increasing the vertical dimension is that when entering low spaces such as under the bed, the passability of the robot becomes poor and it is difficult to adapt to low spaces. Similarly, the disadvantage of increasing the horizontal dimension is that it is difficult to adapt to spaces with a small horizontal dimension.

[0003] In the existing patented technology CN109381121B floor sweeping robot, it is recorded that it includes: a lower body and a rotating body rotatably connected to the lower body. The rotating body can rotate relative to the lower body between a folded position and an unfolded position. In the folded position, at least a part of the rotating body is located above the lower body to reduce the horizontal dimension of the floor sweeping robot. This floor sweeping robot can balance a larger volume and stronger space adaptability. It can not only adapt to areas with a small vertical space (low spaces), but also adapt to areas with a small horizontal space.

[0004] However, in actual use, the machine will still occasionally hit obstacles, and the precision parts of the floor sweeping robot are prone to looseness and damage after being impacted multiple times, which affects the use and reduces the service life of the robot. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an anti-collision floor sweeping robot, which solves the problem that in actual use, the machine will still occasionally hit obstacles, and the precision parts of the floor sweeping robot are prone to looseness and damage after being impacted multiple times, which affects the use and reduces the service life of the robot.

[0006] To achieve the above purpose, the utility model provides an anti-collision floor sweeping robot, which includes a body, a control device and an anti-collision component. The control device is installed above the body. The anti-collision component includes a mounting block, a telescopic rod, an anti-collision plate, a mounting ring and an elastic member. The mounting block is fixedly connected to the body and is located above the body. The telescopic rod is fixedly connected to the mounting block and is located on the side of the mounting block away from the body. The anti-collision plate is fixedly connected to the telescopic rod and is located at the end of the telescopic rod away from the mounting block. The mounting ring is fixedly connected to the body and is located on the side of the body away from the mounting block. The elastic member is installed on the mounting ring, and the elastic member drives the anti-collision plate to move.

[0007] Among them, the elastic member includes a mounting base, a support cylinder, and an elastic element. The mounting base is fixedly connected to the mounting ring and is located on the side of the mounting ring away from the main body; the support cylinder is fixedly connected to the mounting base and is located on the side of the mounting base away from the mounting ring; the elastic element is mounted on the support cylinder, and the elastic element drives the anti-collision plate to move.

[0008] Among them, the elastic element includes a protruding rod, a connecting block, and an elastic part. The protruding rod is slidably connected to the support cylinder and is located on the side of the support cylinder away from the mounting base; the connecting block is fixedly connected to the protruding rod and is located on the side of the protruding rod away from the support cylinder and is connected to the anti-collision plate; the elastic part is mounted in the support cylinder, and the elastic part drives the protruding rod to move.

[0009] Among them, the elastic part includes a connecting rod and a spring. The connecting rod is fixedly connected to the support cylinder and is located on the side of the support cylinder away from the protruding rod and is connected to the protruding rod; the spring is sleeved on the outside of the connecting rod, and both ends of the spring respectively abut against the protruding rod and the support cylinder.

[0010] Among them, the elastic element further includes a sliding strip. The sliding strip is fixedly connected to the protruding rod and is located on the side of the protruding rod close to the support cylinder and abuts against the support cylinder.

[0011] For an anti-collision sweeping robot of the present utility model, the mounting block is fixedly installed above the main body through bolts. One end of the telescopic rod is installed on the mounting block through bolts, and the anti-collision plate is fixedly installed at one end of the telescopic rod away from the mounting block, so that the anti-collision plate can move back and forth. The mounting ring is fixedly installed on the outside of the main body through bolts, and the elastic member is installed on the outside of the mounting ring. The elastic member drives the anti-collision plate to move to the side away from the main body, and at the same time absorbs the energy during collision when the anti-collision plate hits an obstacle, thereby preventing the sweeping robot from directly hitting the obstacle and preventing the precision parts of the sweeping robot from loosening, thus improving the service life of the robot.

The embodiments described by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0018] The first embodiment of this application is as follows:

[0019] Please refer to Figures 1 to 3 , Figure 1 It is a front view of a collision - proof sweeping robot according to the first embodiment of the present utility model, Figure 2 It is a schematic diagram of the overall structure of a collision - proof sweeping robot according to the first embodiment of the present utility model, Figure 3 It is a schematic diagram of the internal structure of the support cylinder according to the first embodiment of the present utility model.

[0020] The present utility model provides a collision - proof sweeping robot, which includes a main body 100, a control device and an anti - collision component. The anti - collision component includes a mounting block 101, a telescopic rod 102, an anti - collision plate 103, a mounting ring 104 and an elastic member. The elastic member includes a mounting base 105, a support cylinder 106 and an elastic element. The elastic element includes an extending rod 107, a connecting block 108, a slide bar 111 and an elastic part. The elastic part includes a connecting rod 109 and a spring 110. By this solution, the problem that in actual use, the machine still occasionally hits obstacles, and the precision parts of the sweeping robot are prone to looseness and damage after being impacted multiple times, affecting the use and reducing the service life of the robot is solved.

[0021] For this specific embodiment, the main body 100 is the sweeping robot described in the existing patent technology CN109381121B. The main body 100 can balance a relatively large volume and strong space adaptability. It can adapt to both areas with a small vertical space (low - lying space) and areas with a small horizontal space. By this solution, the sweeping robot is prevented from directly hitting obstacles, and the precision parts of the sweeping robot are prevented from loosening, thereby improving the service life of the robot.

[0022] Among them, the mounting block 101 is fixedly connected to the body 100 and is located above the body 100. The telescopic rod 102 is fixedly connected to the mounting block 101 and is located on the side of the mounting block 101 away from the body 100. The anti-collision plate 103 is fixedly connected to the telescopic rod 102 and is located at one end of the telescopic rod 102 away from the mounting block 101. The mounting ring 104 is fixedly connected to the body 100 and is located on the side of the body 100 away from the mounting block 101. The elastic member is installed on the mounting ring 104, and the elastic member drives the anti-collision plate 103 to move. The mounting block 101 is fixedly installed above the body 100 by bolts. One end of the telescopic rod 102 is installed on the mounting block 101 by bolts. The anti-collision plate 103 is fixed to one end of the telescopic rod 102 away from the mounting block 101, so that the anti-collision plate 103 can move back and forth. The mounting ring 104 is fixed to the outside of the body 100 by bolts. The elastic member is installed on the outside of the mounting ring 104. The elastic member drives the anti-collision plate 103 to move to the side away from the body 100. At the same time, when the anti-collision plate 103 hits an obstacle, it absorbs the energy during the collision, thus preventing the sweeping robot from directly hitting the obstacle and preventing the precision parts of the sweeping robot from becoming loose, thereby improving the service life of the robot.

[0023] Secondly, the mounting base 105 is fixedly connected to the mounting ring 104 and is located on the side of the mounting ring 104 away from the body 100; the support cylinder 106 is fixedly connected to the mounting base 105 and is located on the side of the mounting base 105 away from the mounting ring 104; the elastic element is installed on the support cylinder 106, and the elastic element drives the anti-collision plate 103 to move. The mounting base 105 is fixed to the side of the mounting ring 104 away from the body 100 by bolts. The support cylinder 106 is installed on the mounting base 105 by bolts. Through the mounting base 105, the support cylinder 106 is stably installed on the mounting ring 104. The elastic element is installed in the support cylinder 106, and the elastic element drives the anti-collision plate 103 to move to the side away from the body 100.

[0024] Meanwhile, the extending rod 107 is slidably connected to the support cylinder 106 and is located on the side of the support cylinder 106 away from the mounting base 105; the connecting block 108 is fixedly connected to the extending rod 107, is located on the side of the extending rod 107 away from the support cylinder 106, and is connected to the anti-collision plate 103; the elastic member is installed in the support cylinder 106, the elastic member drives the extending rod 107 to move, the extending rod 107 is slidably installed inside the support cylinder 106, so that the extending rod 107 can move in the support cylinder 106, the connecting block 108 is installed at one end of the extending rod 107 extending out of the support cylinder 106 by bolts, and the side of the connecting block 108 away from the extending rod 107 is connected to the anti-collision plate 103, so that the extending rod 107 can drive the anti-collision plate 103 to move. The elastic member is installed inside the support cylinder 106, and the elastic member drives the extending rod 107 to move in the support cylinder 106. At the same time, in cooperation with the extending rod 107, the anti-collision plate 103 can move more stably.

[0025] In addition, the connecting rod 109 is fixedly connected to the support cylinder 106, is located on the side of the support cylinder 106 away from the extending rod 107, and is connected to the extending rod 107; the spring 110 is sleeved outside the connecting rod 109, and both ends of the spring 110 respectively abut against the extending rod 107 and the support cylinder 106. The connecting rod 109 is a telescopic short rod. One end of the connecting rod 109 is installed inside the support cylinder 106 by bolts, and the other end of the connecting rod 109 is connected to the extending rod 107 by bolts. The spring 110 is sleeved outside the connecting rod 109. By means of the connecting rod 109, the phenomenon that the spring 110 is bent is avoided. Both ends of the spring 110 respectively abut against the support cylinder 106 and the extending rod 107. By the elastic force of the spring 110, the extending rod 107 is driven to move away from the main body 100, and the energy during collision is absorbed by the spring 110.

[0026] Finally, the sliding strip 111 is fixedly connected to the extending rod 107, is located on the side of the extending rod 107 close to the support cylinder 106, and abuts against the support cylinder 106. The sliding strip 111 is installed on the extending rod 107 by bolts. The support cylinder 106 has a chute cooperating with the sliding strip 111. By abutting the sliding strip 111 against the support cylinder 106, the extending rod 107 is prevented from rotating in the support cylinder 106, so that the extending rod 107 stably drives the anti-collision plate 103 to move.

[0027] When using an anti-collision sweeping robot according to this embodiment, when the sweeping robot collides, the anti-collision plate 103 abuts against an obstacle. At the same time, the telescopic rod 102 retracts to slow down the moving speed of the robot. Meanwhile, the anti-collision plate 103 compresses the spring 110 through the extending rod 107, so that the spring 110 absorbs the energy during the collision, thereby preventing the sweeping robot from directly hitting the obstacle and avoiding the loosening of the precision parts of the sweeping robot, thus improving the service life of the robot.
