Description

[0001] This application is a divisional application of the patent application with application number 202110317599.1 (the filing date of the original application is March 25, 2021, and the name of the invention is Cleaning vehicle body shell structure and cleaning robot). Technical Field

[0002] The invention relates to the technical field of cleaning tools, in particular to a cleaning robot. Background Art

[0003] In recent years, with the development of social economy and the improvement of family living standards, furniture cleaning has gradually entered the era of intelligence and mechanization. Cleaning robots that have emerged are becoming more and more popular among families because of their automatic cleaning and other effects. Cleaning robots can liberate people from furniture cleaning work, effectively reduce people’s workload in home cleaning, and alleviate people’s fatigue during furniture cleaning. Cleaning robots clean up the garbage on the ground through direct brushing, vacuum cleaning and other technologies.

[0004] Generally, most cleaning robots are equipped with a water tank, which is used to provide cleaning liquid so that the cleaning robot can clean the floor. In order to facilitate operation, the cover of the water tank needs to be opened and closed relative to the body of the robot at all times, so that the operator can replenish the cleaning liquid or detergent in the water tank and observe the situation in the water tank to ensure that there is no risk of leakage. However, most existing water tanks are directly hinged with ordinary hinges, which can easily cause the hinges to wear out after long-term use, resulting in the cover of the water tank not being able to close tightly. When the cleaning robot is moving, the water in the water tank is easy to shake out through the gap, which not only causes more water stains on the body of the robot, but also the residual water dripping on the ground affects the cleaning effect.

[0038] like Figure 1 As shown, an embodiment of the present invention provides a cleaning robot 1000, including a cleaning body shell structure, a body accessory structure disposed inside the cleaning body shell structure, and a cleaning structure connected to the body accessory structure, so as to realize the cleaning work of the cleaning robot 1000 relative to the ground. Among them, the cleaning body shell structure mainly plays a protective role.

[0039] The following is a specific description of the cleaning vehicle body shell structure.

[0040] like Figure 1-Figure 5 As shown, a cleaning vehicle body shell structure provided by an embodiment of the present invention includes a first hinge assembly 50, a vehicle frame 10 and a vehicle shell 20 covered on the outside of the vehicle frame 10; a water tank 31 is arranged in the vehicle shell 20, and a water tank cover is connected to the top of the water tank 31, and one end of the water tank cover is hinged to the vehicle frame 10 through the first hinge assembly 50; the first hinge assembly 50 includes a hinge 51, an articulated arm 52 and an articulated seat 53, one end of the hinge 51 is connected to the articulated arm 52, and the other end of the hinge 51 is connected to the articulated seat 53, the articulated arm 52 is used to connect to the water tank cover, the articulated seat 53 is used to connect to the vehicle frame 10, and the articulated seat 53 has an escape space 533; when the water tank cover is closed relative to the water tank 31, part of the articulated arm 52 can be accommodated in the escape space 533; when the water tank cover is opened relative to the water tank 31, part of the articulated arm 52 can be moved out of the escape space 533.

[0041] Specifically, the vehicle frame 10 mainly plays a supporting role so that the vehicle body accessory structure can be stably installed and operate normally. The vehicle shell 20 is wrapped around the outside of the vehicle frame 10, mainly playing a protective role, while ensuring that the vehicle body accessory structure can be accommodated in a relatively safe environment, reducing damage to the vehicle body accessory structure. The vehicle shell 20 forms a cavity, in which a water tank 31 or a control system structure can be installed. Among them, taking the cavity formed in the vehicle shell 20 for installing the water tank 31 as an example, the water tank 31 can be embedded in the cavity, or the vehicle shell 20 itself is surrounded by the water tank 31, and the top of the water tank 31 has a water tank cover, the water tank 31 is used to store cleaning liquid, and one side of the water tank cover is hinged to the vehicle frame 10, so that the water tank cover can be opened and closed relative to the water tank 31. Among them, the water tank cover is mainly hinged to the vehicle frame 10 through the first hinge assembly 50.

[0042] The first hinge assembly 50 includes a hinge 51, an articulated arm 52 and an articulated seat 53. The hinge 51 includes a first rotating leaf 511, a second rotating leaf 512 and a rotating shaft connected therebetween. The first rotating leaf 511 and the second rotating leaf 512 are both rotatably connected to the rotating shaft. The first rotating leaf 511 is fixedly connected to the articulated arm 52, and the second rotating leaf 512 is fixedly connected to the articulated seat 53. The articulated arm 52 is used to connect to the water tank cover, and the articulated seat 53 is used to connect to the vehicle frame 10. An avoidance space 533 is provided on the articulated seat 53 to accommodate part of the structure of the articulated arm 52.

[0043] In actual use, the water tank cover rotates toward the side close to the water tank 31 by using the setting of the hinge 51 under the action of external force, and the water tank cover can drive the hinged arm 52 to rotate synchronously toward the side close to the hinge seat 53, so that part of the hinged arm 52 can be accommodated in the avoidance space 533, thereby tightly fastening the water tank cover relative to the water tank 31, and the avoidance space 533 has a limiting direction along the vertical direction for the hinged arm 52, thereby further improving the tightness of the water tank cover relative to the water tank 31. At the same time, the water tank cover can also rotate toward the side away from the water tank 31 by using the setting of the hinge 51 under the action of external force, and the water tank cover drives the hinged arm 52 to rotate synchronously toward the side away from the hinge seat 53, so that the part of the hinged arm 52 extending into the avoidance space 533 moves out, thereby realizing the opening of the water tank cover relative to the water tank 31. During the entire opening and closing process, the setting of the avoidance space 533 can greatly increase the contact space of the articulated arm 52 relative to the articulated seat 53, thereby increasing the opening space and closing space of the water tank cover relative to the water tank 31. Compared with the prior art in which the water tank cover is easily worn during the opening and closing process, the cleaning vehicle body shell structure provided in this embodiment uses the cooperation of the articulated arm 52 and the articulated seat 53 relative to the hinge 51 to reduce the contact space between the water tank cover and the vehicle frame 10. At the same time, the setting of the avoidance space 533 on the articulated seat 53 increases the rotation space for the articulated arm 52 to rotate relative to the articulated seat 53, thereby further reducing the wear of the water tank cover relative to the water tank 31 during the opening and closing process, thereby ensuring that the water tank cover has sufficient tightness relative to the water tank 31.

[0044] like Figure 2-Figure 5 As shown, in some embodiments, the hinged arm 52 includes a first bending portion 521 bent along a first direction and a second bending portion 522 bent along a second direction, and the two are arranged at an angle, and one end of the first bending portion 521 away from the second bending portion 522 is connected to the water tank cover, and one end of the second bending portion 522 away from the first bending portion 521 is connected to the hinge 51.

[0045] Specifically, the first bending portion 521 and the second bending portion 522 are bent in two different directions, respectively, so that a large space can be reserved between the first bending portion 521 and the second bending portion 522, so that when the end of the first bending portion 521 away from the second bending portion 522 is connected to the water tank cover, and the end of the second bending portion 522 away from the first bending portion 521 is connected to the first rotating leaf 511 of the hinge 51, the distance between the water tank cover and the hinge 51 is increased, that is, the water tank cover does not need to be directly connected to the hinge 51. At the same time, the second rotating leaf 512 of the hinge 51 is connected to the vehicle frame 10 through the hinge seat 53, so that not only does the hinge 51 and the vehicle frame 10 not need to be directly connected, but also the distance between the water tank cover and the vehicle frame 10 is increased by the arrangement of the hinge 51, the hinge arm 52 and the hinge seat 53. At this time, when the water tank cover is opened and closed relative to the water tank 31, there is no direct contact between the water tank cover and the vehicle frame 10, and between the water tank cover and the hinge 51, so no wear will occur. Moreover, it is precisely because the articulated arm 52 is provided with the first bending portion 521 and the second bending portion 522 arranged in two different directions that not only the rotation space of the water tank cover during opening and closing is increased, but also the wear of the water tank cover can be avoided.

[0046] The first direction is horizontally to the left, and the second direction is vertically upward, that is, the first bending portion 521 is bent and extended horizontally to the left, and the second bending portion 522 is bent and extended vertically upward.

[0047] like Figure 2-Figure 5 As shown, in some embodiments, the first bending portion 521 includes a first upper section 5211, a first middle section 5212 and a first lower section 5213 which are connected in sequence, and the three form a "Z" shape structure, the first middle section 5212 is inclined downward from the first upper section 5211 toward the first lower section 5213, the first upper section 5211 is used to connect to the water tank cover, and the first lower section 5213 is used to connect to the second bending portion 522; the second bending portion 522 includes a second upper section 5221, a second middle section 5222 and a second lower section 5223 which are connected in sequence, and the three form a "Z" shape structure, the second upper section 5221 is connected to the hinge 51, and the second lower section 5223 is connected to the first bending portion 521.

[0048] That is to say, the first bending portion 521 and the second bending portion 522 are both bent in a "Z" shape. The first lower section 5213 in the first bending portion 521 is connected to the second lower section 5223 in the second bending portion 522, and the two are at an angle of 90 degrees. The first bending portion 521 extends horizontally to the left, so the first lower section 5213 extends horizontally to the left and transitions to the first middle section 5212, the first middle section 5212 tilts upward and continues to extend to the left, and transitions to the first upper section 5211, there is a height difference between the first upper section 5211 and the first lower section 5213, and the first upper section 5211 continues to extend horizontally to the left, thereby forming the first bending portion 521. Therefore, in the first bending portion 521, the extended end of the first upper section 5211 is used to connect the water tank cover, the first middle section 5212 is used for transition, and the first lower section 5213 is used to connect the hinge 51 through the second bending portion 522.

[0049] Similarly, the second bending portion 522 extends vertically upward, so the second lower section 5223 extends vertically upward from the connection with the first lower section 5213 and transitions to the second middle section 5222. The second middle section 5222 extends horizontally to the left for a certain distance and then transitions to the second upper section 5221. The second upper section 5221 extends vertically upward, thereby forming the second bending portion 522. In the second bending portion 522, the second upper section 5221 is used to connect with the first hinge 511 of the hinge 51. As for the entire hinge arm 52, the first lower section 5213, the second lower section 5223 and the second middle section 5222 form a U shape for insertion into the avoidance space 533 of the hinge seat 53.

[0050] like Figure 2-Figure 5 As shown, in some embodiments, ribs are provided on both sides of the first lower section 5213 along its own width, on both sides of the second lower section 5223 along its own width, on both sides of the second middle section 5222 along its own width, and on both sides of the second upper section 5221 along its own width. The ribs on the first lower section 5213 extend toward the inside of the reserved space between the first bending portion 521 and the second bending portion 522, and the ribs on the second lower section 5223, the second middle section 5222, and the second upper section 5221 all extend in a direction away from the inside of the reserved space between the first bending portion 521 and the second bending portion 522.

[0051] like Figure 2-Figure 5As shown, in some embodiments, the first hinge assembly 50 further includes a connecting plate 54, which is fixedly arranged at one end of the first bending portion 521 away from the second bending portion 522, and the connecting plate 54 is used to connect the water tank cover. In other words, the end of the articulated arm 52 away from the articulated seat 53 is fixed to the water tank cover through the connecting plate 54. The edge of the water tank cover is provided with a vertically extending cover edge, and the connecting plate 54 is arranged in an L shape. The horizontal side of the connecting plate 54 is fixedly arranged at the first upper section 5211 in the first bending portion 521 by bolts, and the vertical side of the connecting plate 54 is fixed to the cover edge by screws, thereby realizing the installation of the articulated arm 52 and the water tank cover. Among them, a triangular rib is also arranged between the horizontal side and the vertical side to play a role in structural reinforcement.

[0052] like Figure 2-Figure 5 As shown, in some embodiments, the hinge seat 53 includes an L-shaped mounting plate 531 and a reinforcing plate 532 connected to the mounting plate 531 , and the mounting plate 531 has an avoidance opening 5313 , and the avoidance opening 5313 and the reinforcing plate 532 together form an avoidance space 533 .

[0053] Specifically, the "L"-shaped mounting plate 531 includes a first vertical plate section 5311 and a first horizontal plate section 5312, and the first vertical plate section 5311 and the first horizontal plate section 5312 are both arranged in a U-shape, and the U-shaped opening of the first vertical plate section 5311 is connected to the U-shaped opening of the first horizontal plate section 5312, so that the avoidance opening 5313 on the mounting plate 531 is formed by the cooperation of the two U-shaped openings. The reinforcing plate 532 is arranged in a right triangle shape and is connected between the first vertical plate section 5311 and the first horizontal plate section 5312. There are two reinforcing plates 532, and the two reinforcing plates 532 are respectively arranged on both sides of the U-shaped opening. The first vertical plate section 5311 in the mounting plate 531 is fixedly connected to the second rotating page 512 of the hinge 51 on the side facing the water tank cover, and the reinforcing plate 532 is fixedly arranged on the side of the mounting plate 531 away from the second rotating page 512. Thus, the two reinforcing plates 532 and the avoidance opening 5313 on the mounting plate 531 together form an avoidance space 533 , so that a portion of the first lower section 5213 , a portion of the second lower section 5223 and a portion of the second middle section 5222 on the hinged arm 52 can extend into the avoidance space 533 .

[0054] The mounting plate 531 is fixed to the second rotating leaf 512 by rivets or screws, and the corresponding second upper section 5221 of the articulated arm 52 is fixed to the first rotating leaf 511 by rivets or screws. At the same time, the first horizontal plate section 5312 in the mounting plate 531 is used to connect with the vehicle frame 10 to achieve the installation of the articulated seat 53 relative to the vehicle frame 10. A connecting ear 5314 is provided at one end of the first vertical plate section 5311 in the mounting plate 531 away from the first horizontal plate section 5312, and the connecting ear 5314 can be fixed to the vehicle frame 10, thereby further improving the connection reliability of the articulated seat 53 relative to the vehicle frame 10.

[0055] like Figure 2-Figure 5 As shown, in some embodiments, the hinge seat 53 further includes a fixing plate 534, the mounting plate 531 is fixedly arranged on the fixing plate 534, and the fixing plate 534 is used to be fixedly arranged on the vehicle frame 10; a waist-shaped hole 5315 is arranged on one side of the mounting plate 531 for connecting with the fixing plate 534. That is, the fixing plate 534 is fixedly connected to the side of the first horizontal plate section 5312 away from the first vertical plate section 5311, and the fixing plate 534 is in direct contact with the vehicle frame 10 and is fixedly connected to the vehicle frame 10. At the same time, waist-shaped holes 5315 are arranged on the first horizontal plate section 5312, and the number of waist-shaped holes 5315 is four, two waist-shaped holes 5315 form a group, and the two groups of waist-shaped holes 5315 are respectively arranged on both sides of the width direction of the U-shaped first horizontal plate section 5312. The waist-shaped hole 5315 can be fixed to the fixing plate 534 by bolts passing through the waist-shaped hole 5315. At the same time, the structure of the waist-shaped hole 5315 can make the mounting plate 531 slightly displaced relative to the fixing plate 534, thereby achieving fine adjustment of the position of the mounting plate 531 relative to the fixing plate 534. Such a setting not only facilitates the flexible installation of the mounting plate 531 relative to the fixing plate 534, but also further improves the installation flexibility by finely adjusting the mounting plate 531 to adapt to the position of the articulated arm 52.

[0056] like Figure 2-Figure 5 As shown, in some embodiments, a slot 5344 is provided on a side of the fixing plate 534 facing away from the mounting plate 531 , and the fixing plate 534 is fixed to the vehicle frame 10 through the slot 5344 .

[0057] Specifically, the fixing plate 534 is arranged in a T-shape rotated 90 degrees, and includes a second horizontal plate section 5341 and a second vertical plate section 5342. One end of the second vertical plate section 5342 is bent toward a side close to the mounting plate 531, and one end of the second horizontal plate section 5341 away from the second vertical plate section 5342 is bent vertically downward to form a bending flange 53411, and the bending flange 53411 and a part of the second horizontal plate section 5341 together form a clamping groove 5344. The vehicle frame 10 includes two parallel and spaced square tubes 11, and the fixing plate 534 is clamped on the outside of the two square tubes 11 through the clamping groove 5344. At the same time, a plurality of mounting long holes spaced along the length direction of the square tube 11 are provided in the second horizontal plate section 5341, and the fasteners of screws are passed through the mounting long holes to be fixed to the square tube 11. Moreover, it is precisely because of the setting of the long installation hole that the position of the fixing plate 534 relative to the square tube 11 can be easily adjusted, thereby facilitating the adjustment of the position of the hinge seat 53 relative to the vehicle frame 10, so as to better adapt to the water tank cover.

[0058] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, in some embodiments, the cleaning vehicle body shell structure further includes a second hinge assembly 60 ; a control box is disposed in the vehicle shell 20 , and the control box has a control box cover 41 , and the control box cover 41 is movably connected to the vehicle frame 10 via the second hinge assembly 60 .

[0059] Specifically, the control box and the water tank 31 are arranged at intervals along the forward direction of the cleaning robot 1000, and a steering wheel cover 70 is provided between the two, and the steering wheel is convenient for the operator to operate. The control box is used to install the control system and the control panel, etc., so the control box has a control box cover 41 to protect the control system and the control panel. The control box cover 41 is rotatably connected to the vehicle frame 10 through the second hinge assembly 60, so that the control box cover 41 can be opened and closed relative to the control box body.

[0060] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, the second hinge assembly 60 includes a connecting seat 61, a fixed seat 62 and a first connecting rod 63; the connecting seat 61 is connected to the control box cover 41, the fixed seat 62 is connected to the vehicle frame 10, one end of the first connecting rod 63 is rotatably connected to the connecting seat 61, and the other end of the first connecting rod 63 is rotatably connected to the fixed seat 62.

[0061] Specifically, the connecting seat 61 is used to connect with the control box cover 41, and the fixing seat 62 is used to connect with the vehicle frame 10. Among them, four connecting holes 6121 are provided on the connecting seat 61, and bolts or screws can pass through the connecting holes 6121 to be fixedly connected with the control box cover 41. Two fixed long holes 6221 are provided on the fixing seat 62, and bolts or screws can pass through the fixed long holes 6221 to be fixed with the vehicle frame 10. Moreover, due to the setting of the fixed long holes 6221, the position of the fixing seat 62 relative to the vehicle frame 10 can be fine-tuned to improve the connection flexibility. The fixing seat 62 and the connecting seat 61 are connected by a first connecting rod 63, that is, one end of the first connecting rod 63 is rotatably connected to the connecting seat 61 by a rivet, and the other end of the first connecting rod 63 is rotatably connected to the fixing seat 62 by another rivet. When the control box cover 41 is opened or closed relative to the control box, the first connecting rod 63 rotates at the point where the first connecting rod 63 is connected to the fixing seat 62, and the rotation connection between the first connecting rod 63 and the connecting seat 61 ensures that the control box cover 41 has a certain degree of freedom of movement. Among them, one end of the first connecting rod 63 connected to the fixing seat 62 is tilted upward to form a tilting portion.

[0062] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, in some embodiments, the second hinge assembly 60 also includes a second connecting rod 64; one end of the second connecting rod 64 is hinged to the connecting seat 61, and the other end is hinged to the fixed seat 62; the first connecting rod 63 is provided with an avoidance groove, which is used to avoid the hinge axis of the second connecting rod 64 and the fixed seat 62.

[0063] Specifically, the connecting seat 61 and the fixing seat 62 are both arranged in an L shape, that is, both have a vertical plate and a flat plate. Take the example that the connecting seat 61 includes a first vertical plate 611 and a first flat plate 612, and the fixing seat 62 includes a second vertical plate 621 and a second flat plate 622. The connecting hole 6121 is arranged on the first flat plate 612 so as to be pressed tightly against the control box cover 41. The fixed long hole 6221 is arranged on the second flat plate 622 so as to be pressed tightly against the vehicle frame 10. The two ends of the first connecting rod 63 are rotatably connected to the first vertical plate 611 and the second vertical plate 621 respectively, and the two ends of the second connecting rod 64 are also rotatably connected to the first vertical plate 611 and the second vertical plate 621 respectively. Among them, the first connecting rod 63 is arranged on the same side of the first vertical plate 611 and the second vertical plate 621, and the second connecting rod 64 is arranged on the other same side of the first vertical plate 611 and the second vertical plate 621.

[0064] One end of the second connecting rod 64 is rotatably connected to the first vertical plate 611 through a rivet, and the other end is rotatably connected to the second vertical plate 621 through another rivet. Moreover, a first avoidance groove 631 is provided in the middle of the first connecting rod 63, and when the first connecting rod 63 is retracted relative to the second vertical plate 621, a rivet connected to the second connecting rod 64 can be accommodated in the first avoidance groove 631. Correspondingly, a second avoidance groove 641 is provided in the middle of the second connecting rod 64, and the second avoidance groove 641 is used to avoid the rivet connecting the first connecting rod 63 and the first vertical plate 611.

[0065] At the same time, the first connecting rod 63 is provided with two first rivet holes 632 at one end for connecting the first vertical plate 611, so that one of the first rivet holes 632 can be selected to be rotatably connected to the first vertical plate 611. The second connecting rod 64 is provided with two second rivet holes at one end for connecting the first vertical plate 611, so that one of the second rivet holes can be selected to be rotatably connected to the first vertical plate 611. Moreover, four third rivet holes 6111 are provided on the first vertical plate 611, so that the first connecting rod 63 and the second connecting rod 64 can select the third rivet holes 6111 at appropriate positions according to needs. Such a setting can facilitate the adjustment of the distance between the connecting seat 61 and the fixing seat 62, thereby adjusting the angle and distance between the control box cover 41 and the control box body, and improving the tightness of the connection between the two.
