Material collecting device, intelligent mower and self-moving equipment

Abstract

The invention provides a material collecting device, an intelligent mower and self-moving equipment. The material collecting device comprises a collecting box, moving wheels, a rolling brush assembly and a lifting adjusting structure. The rolling brush assembly is hung on the lifting part, and the operating part lifts the rolling brush assembly through the lifting part and can drive the rolling brush assembly to ascend and descend. Therefore, according to the concave-convex degree of the working ground and the difference of the sizes of obstacles on the working ground, the height of the rolling brush assembly can be adjusted through movement of the operating piece, and therefore the rolling brush assembly can move on the working ground more smoothly, and the possibility that the rolling brush assembly is hindered by the obstacles is reduced. Moreover, due to the fact that the shell and the collecting box are connected in a lifting mode, and the lifting piece is of a structure with certain flexibility such as a transmission rope or a transmission belt, when the rolling brush makes contact with the working ground or an obstacle on the working ground, the rolling brush assembly can adaptively float and adjust the height, and self-adaptive passive adjustment is achieved. Therefore, the material collecting device can better move on the working ground and collect the objects to be collected.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application and are not used to limit the present application. In the present application, unless otherwise stated, the directional words used, such as "up", "down", "left", and "right", generally refer to the up, down, left, and right of the device in actual use or working state, specifically the drawing direction in the accompanying drawings.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0022] The present application provides a material collection device, an intelligent lawn mower and a self-moving device, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0023] See also Figure 1 , an embodiment of the present application provides a material collecting device 20 , wherein the material collecting device 20 includes a collecting box 400 and a roller brush assembly 500 , and a moving wheel 420 is disposed on the collecting box 400 .

[0024] Here, the collection box 400 has a first receiving space, see Figure 2 , a first opening 411 is provided on the collection box 400, and the first opening 411 is connected to the first receiving space. Usually, the first opening 411 is located near the bottom of the collection box 400, so that the objects to be collected on the working ground can enter the first receiving space through the first opening 411. Exemplarily, here, a first direction X and a second direction Y perpendicular to each other are defined, the first direction X is parallel to the working ground, and the second direction Y points to a direction away from the working ground. Here, the first opening 411 is provided at a position near the bottom of the front side of the collection box 400 in the first direction X. Usually, when the material collecting device 20 moves, the first direction X is the forward direction of the material collecting device 20, and of course, this embodiment does not constitute an undue limitation thereto.

[0025] In addition, in some embodiments, the collection box 400 may also have a second opening (not shown), which is connected to the first receiving space. Here, the second opening is used to allow the objects to be collected in the first receiving space to leave the first receiving space. For example, the second opening can be directly or indirectly connected to a storage component such as a storage bag, that is, the first opening 411 is used as the entrance of the first receiving space, and the second opening is used as the exit of the first receiving space. In addition, the first receiving space can also be connected to a suction source such as a fan to suck the objects to be collected into the first receiving space and / or suck out the objects to be collected in the first receiving space. Of course, the examples in this embodiment do not constitute an undue limitation to the present application.

[0026] A moving wheel 420 is provided on the side of the collection box 400 close to the working ground, usually at the bottom of the collection box 400, so that the collection box 400 can be moved on the working ground by the moving wheel 420. Here, the number of the moving wheels 420 can be 1, 2, 3, etc. For example, in the example of this embodiment, with a straight line parallel to the first direction X as the central axis, two moving wheels 420 are provided at the bottom of the collection box 400 symmetrically about the central axis. Of course, the example in this embodiment does not constitute an improper limitation thereto.

[0027] Furthermore, it is understandable that the moving wheel 420 can be a driving wheel or a driven wheel. When the moving wheel 420 is a driving wheel with power, the material collecting device 20 can move by itself. When the moving wheel 420 is a driven wheel without power, the material collecting device 20 needs to be driven by the drive head 10. The drive head 10 can be a lawn mower or other drive body, etc., and this embodiment does not constitute an improper limitation to it.

[0028] Here, see Figure 2 The roller brush assembly 500 includes a shell 510 and a roller brush 520 rotatably connected to the shell 510. The shell 510 is rotatably connected or fixedly connected to the collection box 400. For example, the shell 510 is hinged to the collection box 400 through a hinge or a rotating shaft or a connecting rod, so that the shell 510 can rotate relative to the collection box 400. In addition, the roller brush 520 is rotatably arranged on the shell 510, that is, the roller brush 520 is rotatable relative to the collection box 400. Usually, the roller brush 520 is located at the first opening 411. Of course, the example in this embodiment does not constitute an improper limitation thereto. In other embodiments, the shell 510 can also be connected to the collection box 400 in other ways; or, the roller brush assembly 500 may not have the shell 510, and the roller brush 520 is directly rotatably arranged on the collection box 400.

[0029] For example, see Figure 3In the example of the embodiment of the present application, the roller brush assembly 500 further includes a connecting rod assembly 530, which is connected between the housing 510 and the collection box 400. The connecting rod assembly 530 is specifically a parallel four-link assembly. The housing 510 of the roller brush assembly 500 is provided with two parallel connecting rods on both the front and rear sides in a direction perpendicular to both the first direction X and the second direction Y. One end of each connecting rod is hinged to the collection box 400 and the other end is connected to the housing 510, so that the housing 510 is rotatably connected to the collection box 400. Here, when the collection box 400 moves on the working ground, based on the setting of the connecting rod assembly 530, the collection box 400 can adapt to the ups and downs and bumps of the working ground and float accordingly, and then can float to avoid obstacles.

[0030] Of course, it can be understood that in other embodiments, the connecting rod assembly 530 is not limited to a parallel four-bar linkage assembly, and the number and arrangement of the connecting rods can be different from the above examples. It only requires that the shell 510 is rotatably connected to the collection box 400 and can be rotated relative to the collection box 400 to change the relative position relationship between the roller brush assembly 500 and the collection box 400. The example in this embodiment does not constitute an undue limitation to the present application.

[0031] The roller brush 520 of the roller brush assembly 500 is rotatably connected to the housing 510, for example, connected to the housing 510 via a rotating shaft. It is understandable that the roller brush assembly 500 also includes a driving source such as a motor (not shown), and the roller brush 520 is connected to the driving source such as the motor, so that the roller brush 520 can rotate around its axis through the drive of the driving source such as the motor. Figure 2 The roller brush 520 is located near the first opening 411. For example, a portion of the roller brush 520 may extend from the first opening 411 into the first receiving space. Of course, the example in this embodiment does not constitute an improper limitation. When the roller brush 520 rotates, it can lift the objects to be collected and allow the objects to be collected to enter the first receiving space through the first opening 411.

[0032] Also, see Figure 2 and Figure 3 The roller brush assembly 500 may further include a scraper bar 540, which is disposed near the bottom of the housing 510. Generally, the scraper bar 540 may be located at the front side of the housing 510 in the first direction X, that is, the side of the housing 510 away from the collection box 400. By providing the scraper bar 540, the objects to be collected on the working floor may be scraped and collected better, so that the roller brush 520 may lift the objects to be collected and store them in the first storage space of the collection box 400. Of course, in other embodiments, the scraper bar 540 may not be provided, and the example in this embodiment does not constitute an improper limitation thereto.

[0033] Here, the material collecting device 20 can be used to collect leaves, grass leaves, etc. For example, in places such as sports fields, farms, parks, and garden green spaces, lawn mowers are required to be used regularly for trimming and tidying. The lawn mower has a cutting component, and the cutting component is used to cut grass leaves of a certain height. Here, please refer to Figure 1 The material collecting device 20 is assembled on the main body of the lawn mower to collect the grass leaves formed after the lawn mower cuts. The main body of the lawn mower is used as a driving head 10 to drive the material collecting device 20 to move.

[0034] For example, see Figure 2 and Figure 3 The material collecting device 20 further includes a connecting member 100, which is disposed on the collecting box 400, and the connecting member 100 and the housing 510 may be located on the same side of the collecting box 400. Exemplarily, the connecting member 100 and the housing 510 are both disposed on the front side of the collecting box 400 in the first direction X. Here, one end of the connecting member 100 is connected to the collecting box 400, and the other end may be used to connect to the driving head 10 such as the body of the lawn mower, thereby realizing the connection between the body of the lawn mower and the material collecting device 20.

[0035] Of course, it can be understood that in this embodiment, the material collecting device 20 is driven to move by using the main body of the lawn mower as the driving head 10. The main body of the lawn mower includes a main body, a walking device 11 and a cutting assembly. The walking device 11 is arranged on the main body to drive the main body to move, so that the main body of the lawn mower can move from one position to another. The cutting assembly is arranged on the main body to cut grass leaves, etc., which can be a cutting knife, etc. Among them, the walking device 11 can be a crawler structure, a wheel structure or a bionic structure, etc., and this embodiment does not limit it. Exemplarily, when the walking device 11 is a wheel structure, the walking device includes a wheel and a motor for driving the wheel to rotate, and the motor drives the wheel to rotate to drive the main body to move.

[0036] It is understandable that in other embodiments, the specific application scenarios may be different, and the main body of the lawn mower may be replaced by other movable drive heads 10, etc. to drive the material collecting device 20 to move, or the material collecting device 20 may be independently operated, self-driven and movable, etc. The examples in this embodiment do not constitute an undue limitation to the present application.

[0037] Here, the working ground of the work site is usually not a flat ground, but an uneven ground, or there may be various obstacles such as stones on the working ground. If the material collecting device 20 cannot adjust the height distance between the roller brush assembly 500 and the ground according to the changes in the terrain, the material collecting device 20 will not be able to adapt to different working grounds, which will affect the effect of collecting the collected materials, such as being blocked by uneven terrain or obstacles and unable to move. In addition, in some scenes where the working ground is relatively uneven or there are large obstacles such as stones, the effect of the adaptive floating adjustment achieved by the rotation connection between the shell 510 and the collection box 400 will not be sufficient to adapt to the needs of the working ground.

[0038] To this end, further, in the embodiment of the present application, the connection between the aforementioned housing 510 and the collection box 400 is set to be a liftable connection. In this connection mode, when the housing 510 moves relative to the collection box 400, it can drive the roller brush 520 to produce a vertical displacement relative to the collection box 400. Here, illustratively, the housing 510 and the collection box 400 can adopt the aforementioned rotation connection mode. When the housing 510 rotates relative to the collection box 400, the housing 510 and the roller brush 520 can produce a vertical displacement relative to the collection box 400. Of course, in other embodiments, the housing 510 can also be connected to the collection box 400 in other ways, for example, the collection box 400 is provided with a guide rail or a guide rod, and the housing 510 cooperates with the guide rail or the guide rod and can move linearly or curvilinearly relative to the collection box 400, and can drive the roller brush 520 to produce a vertical displacement relative to the collection box 400 when moving.

[0039] In addition, while the housing 510 and the collection box 400 are connected in a liftable manner, please refer to Figure 4 The material collecting device 20 further includes a lifting and adjusting structure 300. The lifting and adjusting structure 300 includes a lifting member 310 and an operating member 320 connected to each other. Here, the roller brush assembly 500 is suspended on the lifting member 310. The operating member 320 lifts the roller brush assembly 500 through the lifting member 310 and can drive the roller brush assembly 500 to rise and fall. For example, please continue to refer to Figure 4 The lifting member 310 extends longitudinally, and the lifting member 310 is connected to the housing 510 of the roller brush assembly 500 to suspend the roller brush assembly 500.

[0040] Here, the operating member 320 can fix the lifting member 310 to apply a force to the lifting member 310. For example, a plurality of connection positions are provided between the aforementioned connecting member 100 and the operating member 320. The connection positions can be provided continuously or at intervals, and this embodiment does not constitute an undue limitation thereto. For example, please refer to Figure 6, a first matching portion 111 is provided on the connecting member 100, and the first matching portion 111 can be a protrusion or the like. Specifically, a connecting frame 110 is provided on the connecting member 100 here, and a bolt is threadedly matched on the connecting frame 110 as a protrusion, and the lower side of the connecting frame 110 in the second direction Y has a receiving gap for assembling the operating member 320. Of course, in other embodiments, the connecting frame 110 may not be provided, and it is only necessary that the first matching portion 111 can be used to be detachably connected to the lifting member 310 or the operating member 320, or the relative position relationship between the connecting frame 110 and the operating member 320 may also be different, and the examples in this embodiment do not constitute an improper limitation thereto.

[0041] Furthermore, corresponding to the first matching portion 111, a fixing portion 321 is also provided on the operating member 320, and the fixing portion 321 is arranged along the longitudinal extension direction of the lifting member 310. Here, the fixing portion 321 may include a plurality of recessed portions, and the recessed portions may be connecting grooves, connecting holes, etc., for example, please refer to Figure 5 Here, the fixing portion 321 may include four connection holes sequentially arranged along the first direction X to provide four spaced connection positions. Of course, it can be understood that in other embodiments, the fixing portion 321 may also be arranged on the lifting member 310, and the example in this embodiment does not constitute an improper limitation thereto.

[0042] Here, the first matching portion 111 can be snap-fitted into any fixing portion 321 in a detachable manner, that is, the operating member 320 can be switched between various connection positions. For example, when the protrusion of the first matching portion 111 is a bolt threadedly fitted on the connecting member 100, the bolt can be turned to withdraw the bolt from the connection hole of the fixing portion 321. At this time, the operating member 320 can be moved to a position corresponding to another connection hole and the bolt, and then the bolt can be turned again to fit the bolt into the connection hole, thereby realizing the position change and fixation of the operating member 320. Here, Figure 5 In the embodiment, the raised portion is matched with the third recessed portion arranged in sequence along the forward direction. When the connection position of the operating member 320 needs to be changed, the operating member 320 can be moved to move any of the other three recessed portions to a position matched with the raised portion. Of course, it can be understood that in other embodiments, the number of recessed portions is not limited to 4, and can be set to other numbers greater than or equal to 2 as needed, so as to achieve the switching of different gear positions of the operating member 320, and the example in this embodiment does not constitute an improper limitation thereto.

[0043] Thus, when each fixing portion 321 fixes the lifting member 310 and the operating member 320, the bottom end of the lifting member 310 has different heights, and the lifting member 310 can drive the rotating assembly 500 connected thereto to move to different heights.

[0044] Here, several recessed parts can be connected by a groove extending along the first direction X, so that when the operating member 320 moves, the protrusion moves along the groove relative to the operating member 320 and matches to the position of any recessed part. The setting of the groove helps to guide and limit the movement of the operating member 320. Of course, in other embodiments, several recessed parts can be set on the connecting member 100 to form several connection positions, and correspondingly, a protrusion is set on the operating member 320 to match with the recessed parts, that is, the first matching part 111 includes several recessed parts, and the fixing part 321 includes a protrusion; or, in other embodiments, the connection position can also be formed by other structures, for example, a part of the connecting member 100 is constructed as a magnetic attraction part as the first matching part 111, and the magnetic attraction part forms several connection positions, and a magnetic element is set on the operating member 320 as the fixing part 321, and the magnetic element can be matched with the magnetic attraction part through magnetism, so that it can switch between several connection positions. The examples in the embodiments of the present application do not constitute an improper limitation to the present application.

[0045] Furthermore, it is understandable that in the embodiments of the present application, the example of setting the connection position on the connecting member 100 is used for illustration. Since the connecting member 100 is connected to the collection box 400, that is, the embodiment of the present application is described by taking the connection position indirectly set on the collection box 400. However, it is understandable that in other embodiments, the connection position may also be directly set on the collection box 400, and the example in this embodiment does not constitute an undue limitation thereto.

[0046] As mentioned above, the operating member 320 can be connected at any connection position, that is, the operating member 320 can be moved and switched between several connection positions, thereby, the operating member 320 can move relative to the collection box 400, and then can drive the lifting member 310 connected to the operating member 320 to move. The lifting member 310 is connected to the shell 510, and then when the lifting member 310 moves, it can drive the shell 510 to rise and fall relative to the collection box 400. In other words, by switching the connection position to which the operating member 320 is connected, the lifting member 310 can be driven to drive the shell 510 to rise and fall relative to the collection box 400. In this way, the height adjustment of the roller brush assembly 500 can be achieved. Among them, the movement of the operating member 320 can be adjusted by manual operation, and can also be achieved by the drive of a driving device such as a motor, and the examples in this embodiment do not constitute an undue limitation to it.

[0047] Exemplarily, here, the lifting member 310 has a free end and a connection end, the free end is connected to the housing 510, and the connection end is connected to the operating member 320, thereby realizing the connection between the housing 510 and the operating member 320. Specifically, here, the lifting member 310 can be a transmission belt. Of course, in other embodiments, the lifting member 310 can also be other structures made of flexible materials such as transmission ropes, etc., and the examples in this embodiment do not constitute an improper limitation thereto.

[0048] It can be seen that in the material collection device 20 provided in the embodiment of the present application, according to the different degrees of unevenness of the working ground and the size of the obstacles on the working ground, the height of the roller brush assembly 500 can be adjusted by moving the operating member 320, so that the roller brush assembly 500 can be better matched with the working ground, so as to move more smoothly on the working ground and reduce the possibility of being blocked by obstacles. In addition, after the height of the roller brush assembly 500 is actively adjusted by the operating member 320, the housing 510 and the collection box 400 can be connected in a lifting manner due to the connecting rod assembly 530 or other structures, and the lifting member 310 adopts a structure with a certain flexibility such as a transmission rope or a transmission belt. When the roller brush 520 contacts the working ground or the obstacles on the working ground, the roller brush assembly 500 can be adaptively floated and raised to achieve adaptive passive adjustment of the height. Thus, the material collection device 20 can better move on the working ground and collect the collected materials.

[0049] Also, see Figure 4 In some embodiments, the lifting and lowering adjustment mechanism further includes a steering member 330, and the lifting member 310 extends downward from the operating member 320 through the steering member 330 to form the aforementioned free end, and the roller brush assembly 500 is connected to the free end. The steering member 330 is located between the roller brush assembly 500 and the operating member 320. Exemplarily, the steering member 330 can be set on the connecting member 100 or directly on the collection box 400. The steering member 330 is used to convert the movement direction of the lifting member 310, and at least a portion of the lifting member 310 located between the free end and the connecting end is matched on the steering member 330, so that when the lifting member 310 moves, the movement directions of the free end and the connecting end are different.

[0050] Here, the steering member 330 is a fixed pulley assembly, for example, see Figure 5The fixed pulley assembly includes a transmission belt disk 331, and a first connecting shaft 332 is provided on the connecting member 100. The transmission belt disk 331 is rotatably connected to the connecting member 100 through the first connecting shaft 332, that is, the transmission belt disk 331 can rotate relative to the connecting member 100 around the axis where the first connecting shaft 332 is located, and the axis of the first connecting shaft 332 is perpendicular to the first direction X and the second direction Y. A part of the lifting member 310 is arranged around the transmission belt disk 331. For example, when the operating member 320 switches between the connection positions, the operating member 320 will be displaced along the first direction X, thereby driving the connection end of the lifting member 310 to move along the first direction X. At this time, the lifting member 310 will drive the transmission belt disk 331 to rotate around the axis of the first connecting shaft, and through the steering effect of the transmission belt disk 331, the free end of the lifting member 310 will move along the second direction Y. Since the free end of the lifting member 310 is connected to the housing 510 of the roller brush assembly 500, the housing 510 and the roller brush 520 on the housing 510 will be lifted and lowered relative to the collection box 400 under the drive of the lifting member 310. Here, in the embodiment where the housing 510 is rotatably connected to the collection box 400, the housing 510 will rotate relative to the collection box 400 and achieve lifting and lowering.

[0051] Here, due to the setting of the steering member 330, the movement direction of the lifting member 310 can be converted, and the movement direction of the free end of the lifting member 310 is different from the movement direction of the connecting end, so that the operating member 320 can achieve the height adjustment of the roller brush assembly 500 without moving in the vertical direction. That is, the movement direction of the operating member 320 can be adjusted according to the needs of structure and convenience of operation, thereby achieving a compact structure and convenient operation.

[0052] Of course, it can be understood that in the examples of the aforementioned embodiments, the movement direction of the free ends of the operating member 320 and the lifting member 310 is horizontal, and the movement direction of the connecting end of the lifting member 310 is vertical, and the angle between the movement direction of the free ends of the operating member 320 and the lifting member 310 and the movement direction of the connecting end of the lifting member 310 is a right angle. However, in other embodiments, it is not limited to the above examples. The movement direction of the free ends of the operating member 320 and the lifting member 310 and the movement direction of the connecting end of the lifting member 310 may be the same, or they may be different and may not be a right angle but may be an angle of other angles, such as 30°, 45°, 60°, 70°, etc. The examples in this embodiment do not constitute an improper limitation to the present application.

[0061] In some embodiments, the lawn mower includes the material collecting device 20 in the aforementioned material collecting device 20 embodiment. The body of the lawn mower in this embodiment can be the drive head 10 in the aforementioned material collecting device 20. The corresponding specific structure can refer to the aforementioned material collecting device 20 embodiment, and this embodiment will not be repeated.

[0062] Accordingly, in order to better achieve the technical effects in the embodiments of the present application, the embodiments of the present application also provide a self-moving device, which includes a drive head 10 and the aforementioned material collecting device 20, the drive head 10 has a walking device, and the drive head 10 is connected to the collection box 400 through the connecting piece 100 of the material collecting device 20.
