The cover assembly 1 can be disposed on the body 2 of the cleaning robot and move along with the body 2, the collision part is configured to collide with an obstacle first, and the sensing part 12 is disposed at a front side of the collision part in a forward direction of the body 2. In practical application, when the body 2 moves forward, when an obstacle appears, the collision surface 121 of the sensing part 12 located in front of the collision part of the cover body 11 first contacts and collides with the obstacle, the collided sensing part 12 can generate a sensing signal, and a control system of the body 2 can know that the obstacle exists in front of the body according to the sensing signal and make an obstacle avoidance.

Compared with the prior art, the damage to the cover body component 1 by a barrier can be avoided, so that the damage to the radar component is avoided, and the influence on the operation of a machine body is avoided; meanwhile, the arrangement of the induction part 12 improves the collision sensitivity of the cover body 11, so that the body 2 can judge the obstacle more reliably. In addition, the anti-collision can be realized only by arranging the induction part 12, the assembly is simple, the materials are fewer, the assembly efficiency is improved, and the production cost is reduced.

It should be noted that the winding angle of the sensing part 12 does not exceed 180 degrees, that is, the sensing part 12 only senses the obstacle located in the forward direction of the machine body 2. Therefore, the obstacle can be sensed in a certain range of the circumferential direction of the collision part, redundant elements can be reduced, and sensing cost is reduced.

In particular embodiments, the sensing portion is configured to extend lengthwise between a first end and a second end; a connecting line between the first end of the sensing part and the central axis along the radial direction is defined as a first connecting line, and a connecting line between the second end of the sensing part and the central axis along the radial direction is defined as a second connecting line; the plane where the first connecting line and the second connecting line are located is perpendicular to the central axis, and the included angle between the first connecting line and the second connecting line is the winding angle of the induction part. Namely, the winding angle of the sensing part is the included angle between the first connecting line and the second connecting line.

The first connection line and the second connection line may be equal or different.

The collision part of the cover body 11 is preferably a round end, which is helpful for realizing the obstacle sensing in all directions, and the first connection is equal to the second connection.

The winding angle of the sensing part 12 may be 165 degrees, 150 degrees, 135 degrees, 120 degrees, 90 degrees, etc.

In some embodiments, referring to fig. 2, the sensing portion 12 includes a strain gauge 122, and the strain gauge 122 is disposed around the circumferential sidewall 111 of the collision portion along the circumferential direction of the collision portion, and has the above-mentioned winding angle and the collision surface 121. When an obstacle appears, the obstacle collides with the collision surface 121 of the strain gauge 122, the strain gauge 122 generates a strain signal during collision, and a control system of the body 2 can know that the obstacle appears according to the strain signal, so as to control the body 2 to avoid.

In a specific embodiment, the number of the strain gauges 122 is 1, and the strain gauges 122 extend lengthwise between the first end and the second end in the circumferential direction of the collision portion. In this case, the strain gauge 122 has a long shape, and can continuously sense an obstacle within a winding angle range.

In other embodiments, the strain gauge 122 is block-shaped, the number of the strain gauges 122 is plural, the plurality of strain gauges 122 are arranged on the circumferential side wall 111 of the collision part at intervals along the circumferential direction of the collision part, and the plurality of strain gauges 122 form the sensing part 12 and extend lengthwise between the first end and the second end. At this time, each strain gauge 122 senses an obstacle, and when one strain gauge 122 generates a strain signal, it indicates that an obstacle is present in front of the machine body 2.

It is understood that the sensing portion 12 may further include a wire or the like electrically connected to the strain gauge 122.

In some embodiments, referring to fig. 3 and 4, the sensing portion 12 includes a plurality of tact switches 123, each tact switch 123 includes a fixed end 1231 and a handle end 1232, the fixed end 1231 of each tact switch 123 is connected to the circumferential sidewall 111 of the collision portion, the fixed ends 1231 of the plurality of tact switches 123 are arranged at the circumferential sidewall 111 along the axial direction of the collision portion, and a side surface of the handle end 1232 of all tact switches 123 facing away from the fixed end 1231 collectively forms the collision surface 121.

In practical use, when the collision surface 121 of the tact switch 123 touches the obstacle, the obstacle generates a pressing force to the push handle end 1232, the pressed push handle end 1232 triggers the tact switch 123 to generate an electric signal, and the control system of the body 2 learns that the obstacle exists in front of the body 2 according to the electric signal, so as to control the body 2 to avoid. By arranging the plurality of tact switches 123 on the circumferential side wall 111 at intervals in order along the circumferential direction of the collision portion within a certain surrounding angle, obstacle sensing within a certain range in the advancing direction of the body 2 is realized.

The tact switch 123 may be a commercially available component, and the specific structure is not described herein.

In some embodiments, referring to fig. 3, 4 and 6, the sensing portion 12 further includes an impact plate 124, the impact plate 124 is floatably connected to the circumferential side wall 111 in a direction intersecting the circumferential side wall 111, the stem ends 1232 are located between the impact plate 124 and the circumferential side wall 111, and a surface of each stem end 1232 constituting the impact surface 121 is in contact with the impact plate 124, and the impact plate 124 can impact the stem end 1232 when floating.

In actual operation, the obstacle directly collides and contacts with the collision sheet 124, and the collision sheet 124 can press down the push handle end 1232 when being collided by the obstacle, so that the tact switch 123 generates an electric signal, and the control system of the machine body 2 learns that the obstacle exists in front of the machine body 2 according to the electric signal, and further controls the machine body 2 to avoid. Meanwhile, when an obstacle appears near the tact switch 123, it can collide with the collision sheet 124 contacting the push-handle end 1232 of the tact switch 123, thereby expanding the sensing range of the tact switch 123.

Further, the collision sheet 124 extends lengthwise along the circumferential direction of the collision wall between the first end and the second end, and the collision surface 121 is formed by all the push-shank ends 1232 to be in contact with the collision sheet 124. At this moment, through setting up the collision piece 124 of rectangular shape, utilize the collision piece 124 of rectangular shape to contact simultaneously all surfaces of formation collision face 121 of all push handle ends 1232, be located the barrier in the region between two adjacent push handle ends 1232, can bump with collision piece 124, so can reduce the quantity of dabbing switch 123 through the setting of collision piece 124, compare and only set up dabbing switch 123, enlarge perception scope greatly, simultaneously can also perceive the barrier in all directions around establishing the within range in succession, reach and improve perception accuracy.

Of course, the collision sheet 124 may also be in a block shape, and one collision sheet 124 is disposed corresponding to each push handle end 1232, or one collision sheet 124 is disposed corresponding to N push handle ends 1232.

In some embodiments, referring to fig. 3, 4 and 10, the sensing portion 12 further includes a compression member, one end of which is connected to the circumferential sidewall 111, and the other end of which is fixedly connected to the collision sheet 124, and the compression member is configured to provide a biasing force to the collision sheet 124 away from the push handle end 1232 when the collision sheet 124 presses the push handle end 1232.

In actual operation, when the collision sheet 124 collides with an obstacle, the obstacle applies a pressure, and the collision sheet 124 moves toward the circumferential side wall 111 under the pressure, so that the collision push handle end 1232 retracts to enable the tact switch 123 to generate an electric signal. At the same time, the striker 124 exerts a compressive force on the compression member, and the compressed compression member provides a biasing force to the striker 124 away from the push-handle end 1232, thereby urging the striker 124 to return to the initial position when the body 2 clears the obstacle.

It will be appreciated that when striker 124 is in the initial position, it just contacts impact surface 121 of push handle end 1232 and no pressure is applied. At this time, the compression member is in a free state.

Wherein, the compression piece can be a spring or a flexible piece such as sponge, silica gel, rubber and the like.

At this time, the collision sheet 124 is connected to the flexible sheet 125, and when the collision sheet 124 receives an obstacle collision, pressure can be provided to the flexible sheet 125, so that the flexible sheet 125 is compressed, and the flexible sheet 125 compresses to drive the collision sheet 124 to press down the push handle end 1232, so that the tact switch 123 generates an electric signal to inform that the obstacle is present in front of the machine body 2. When the body 2 avoids the obstacle, the flexible sheet 125 returns to the initial state when the pressure applied to the flexible sheet 125 by the collision sheet 124 is small, and the collision sheet 124 returns to the initial state along with the flexible sheet 125, thereby resetting the collision sheet 124. Meanwhile, the collision sheet 124 and the circumferential side wall 111 are connected by a flexible sheet 125, so that the installation is facilitated, and the installation stability of the collision sheet 124 can also be improved.

Wherein the outer extension surface of flexible sheet 125 compresses toward the inner extension surface thereof when flexible sheet 125 receives the pressure applied by collision sheet 124.

It is understood that the relief hole 1252 penetrates through the inner and outer extending surfaces of the flexible sheet 125 for the insertion of the pushing stem end 1232.

Further, the inner extending surface of the flexible sheet 125 is bonded to the circumferential side wall 111, and the outer extending surface of the flexible sheet 125 is bonded to the collision sheet 124. Thus saving time and labor.

When assembling the flexible piece 125 and the collision piece 124, the position relationship between the flexible piece 125 and the collision piece 124 is first positioned by the engagement of the positioning rib 1241 and the positioning groove 1251. Thus, the installation is accelerated.

Wherein the positioning rib 1241 protrudes from the flexible sheet 125 or the collision sheet 124.

In some embodiments, referring to fig. 5, the circumferential sidewall 111 has a switch hole 112 therethrough, the fixed end 1231 of each tact switch 123 is located inside the cover body 11 and connected to the circumferential sidewall 111, and the push-handle end 1232 of each tact switch 123 extends out of the switch hole 112.

Thus, the fixed end 1231 of the tact switch 123 is accommodated inside the cover body 11, so that the risk of damage to the tact switch 123 can be reduced, and the cover assembly 1 is more beautiful.

The pressing sheet 126 may be fixed to the cover body 11 by fastening means such as screws.

Further, the fixed end 1231 abuts against the top wall of the collision portion. At this time, the fixing end 1231 is fixed by restricting the movement of the fixing end 1231 by the pressing piece 126, the top wall, and the circumferential side wall 111.

In some embodiments, referring to fig. 3 and 5, the circumferential sidewall 111 has a concave receiving groove 113, the receiving groove 113 extends lengthwise along the circumference of the collision part, the sensing part 12 is located in the receiving groove 113, and partially protrudes out of the receiving groove 113 to form the collision surface 121.

In a specific embodiment, when the sensing part 12 includes the tact switch 123, the fixed end 1231 of the tact switch 123 is connected to the circumferential sidewall 111 at a position opposite to the receiving groove 113. At this time, the switch hole 112 penetrates the groove bottom of the accommodation groove 113.
