Description

A cleaning machine fixing device and a cleaning machine docking station Technical Field

[0001] The present invention relates to the technical field of sweepers, and further to a sweeper fixing device and a sweeper docking station. Background Art

[0002] At present, with the increasing market demand for sweepers, after the sweeper completes its work, it needs to dock at a docking station for sleep or charging. During the docking period, it may encounter severe strong winds, which may blow the sweeper out of the docking station, causing damage to the sweeper and more likely to damage the components and brackets.

[0003] In summary, a cleaning machine fixing device is needed to solve the existing problems.

[0004] Summary of the Invention

[0005] In response to the above technical problems, the purpose of the present invention is to provide a sweeper fixing device and a sweeper docking station, which can effectively fix the sweeper to prevent the sweeper from being blown off in severe winds, and can also unlock the sweeper in time to ensure the normal use and life of the sweeper.

[0006] To achieve the above-mentioned object, the present invention provides a cleaning machine fixing device, which is arranged on a bracket for docking the cleaning machine, and comprises: a first limiting member and a second limiting member, wherein the first limiting member is fixed to the bracket, the cleaning machine is provided with a fixing ring, and the first limiting member passes over a portion of the fixing ring when the cleaning machine is docked on the bracket;

[0007] The second limiting member is rotatably connected to the bracket, one end of the second limiting member is provided with an adjustment portion arranged on the parking path of the sweeper, the other end of the second limiting member is a movable end and is close to the first limiting member, and the movable end can form an enclosed area with the first limiting member;

[0008] In the first state, when the sweeper is docked at the bracket or moving out of the bracket, the adjusting portion is pressed downward, thereby driving the movable end to move in a direction away from the first limiting member, and the enclosed area is opened;

[0009] In the second state, after the sweeper is docked at the bracket, the adjustment part is not pressed, and the movable end moves toward the first limit member through the rebound force of a reset structure, forming the enclosed area passing through part of the fixed ring, thereby locking the sweeper.

[0010] It should be noted that the first limit member and the second limit member can adjust the locking or opening state by the force applied to the adjustment part, making the fixation of the sweeper more convenient and flexible. There is no need to use electric drive to drive such a fixing device, which is more energy-saving and less susceptible to environmental factors.

[0011] In some embodiments, the reset structure is respectively connected to the bracket and the second limit member to provide a rebound force, and when the adjustment part is not compressed, the movable end moves toward the direction of the first limit member due to the action of the rebound force to form the enclosed area.

[0012] The role of the reset structure here is first to provide a rebound force, so that the relative movement of the adjustment part is faster under the drive of the rebound force. In addition, the second limit member is connected to the bracket through the reset structure, which can also make the structures more firm and more reliable.

[0013] In some embodiments, the reset structure includes a spring and a connecting plate, two free ends of the spring are respectively connected to the connecting plate and a side of the second limiting member close to the adjusting portion, and the connecting plate is fixedly connected to the bracket.

[0014] It should be noted that the spring has excellent ductility and resilience, and can adapt to most scenarios. In addition, the connecting plate can provide a connection space so that the relative connection position of the spring can be adjusted to adapt to the size and parameters of other related parts.

[0015] In some embodiments, a shaft sleeve is provided on the first limiting member, and the second limiting member is rotatably connected to the shaft sleeve via a rotating shaft, so that the second limiting member can rotate relative to the first limiting member to adjust the opening or closing of the enclosed area.

[0016] Among them, the sleeve and the rotating shaft can achieve a very good connection effect, so that the second limiter can be rotatably connected to the first limiter, so that the two are arranged adjacently and the structure is more compact, so that the fixing effect on the fixing ring is better.

[0017] In some embodiments, the first limiting member passes through the radial direction of the sleeve, and the sleeve partially wraps the outer periphery of the first limiting member; the second limiting member passes through the radial direction of the rotating shaft, so that the movable end and the adjusting portion provided on the second limiting member are distinguished on both sides of the rotating shaft.

[0018] In some embodiments, the first limit member and the second limit member are both configured as connecting rods having several bent sections, wherein when the sweeper is docked on the bracket, the openings formed by the several bent sections of the second limit member face the docking path of the sweeper; and at least one of the bent sections of the second limit member is located on the docking path of the sweeper.

[0019] It should be noted that the connecting rod with a bending section is a better implementation form. Through several clever bending sections, it is possible to simultaneously create an enclosed area between the first limit member and the second limit member, and it is also possible to adjust the corresponding state of the adjustment part. There is no need for multiple components to be used in combination, which reduces the number of parts and labor costs during assembly.

[0020] In some embodiments, a movable pressure plate is further provided at the end of the adjusting portion, and one side of the movable pressure plate abuts against the bracket fixedly connected to the connecting plate; wherein the top wall of the movable pressure plate cooperates with the walking wheel of the sweeper, and when the walking wheel presses down the movable pressure plate, the adjusting portion is pressed down synchronously so that the movable end moves away from the first limiting member to open the enclosed area.

[0021] The movable pressure plate here increases the contact area between the adjustment part and the travel wheel of the sweeper, and makes it difficult for the adjustment part to be damaged by long-term pressure during work, making the device more reliable and more stable.

[0022] In some embodiments, the top wall of the movable pressure plate is provided with two inclined surfaces; the two inclined surfaces are divided into an entry surface and an exit surface, so that when the walking wheel of the sweeper presses down the entry surface or the exit surface, the enclosed area is opened to adjust the locking state of the fixed ring; wherein, the entry surface and the exit surface intersect and form an intersection line, and the horizontal position of the intersection line is higher than the horizontal position of the bracket to which the connecting plate is fixedly connected.

[0023] It should be noted that the setting of the two inclined surfaces is quite clever, which can increase the effective displacement length of the adjustment part to a certain extent, so that the opening degree of the enclosed area can be adjusted accordingly, and can avoid the situation where the opening of the enclosed area is too small to cooperate with the fixed ring after the walking wheel presses down the movable pressure plate.

[0024] In some embodiments, the end portion fixed to the bracket away from the first limiting member is configured as a fixed hook, and the end portion of the movable end of the second limiting member that cooperates with the fixed hook is set as a movable hook; the highest point of the fixed hook is horizontally positioned higher than the fixed ring; in the first state, the end spaces of the fixed hook and the movable hook abut against each other to form the enclosed area for locking the fixed ring, and in the second state, the movable hook moves in a direction away from the fixed hook, and the enclosed area opens, so that the fixed ring can pass through the opening created by the enclosed area.

[0025] Among them, both the fixed hook and the movable hook have a certain curvature, which can fit better with the edge of the fixed ring, and the outline is more rounded, which is not easy to bump into or scratch other parts.

[0026] Another aspect of the present invention also provides a sweeper docking station, comprising: a bracket for supporting and docking the sweeper; and at least one of the above-mentioned sweeper fixing devices, wherein the sweeper fixing device is correspondingly arranged on the bracket.

[0027] It should be noted that the sweeper fixing device can be set according to factors such as the size and structure of the sweeper, and the sweeper can be fixed in multiple places by utilizing the matching relationship between multiple sets of first limit members and second limit members, which can ensure that the sweeper will not be blown down or over in severe windy environments.

[0028] Compared with the prior art, the sweeper fixing device and sweeper docking station provided by the present invention have the following beneficial effects:

[0029] 1. The cleaning machine fixing device provided by the present invention does not require a driving device. A locking structure relative to the cleaning machine is formed by setting a first limit member and a second limit member. The opening and closing state of the locking structure is driven by the mechanical structure and the movement of the cleaning machine. It has excellent convenience and compatibility, is not prone to malfunction, and has low maintenance costs.

[0030] 2. The cleaning machine fixing device provided by the present invention is provided with a reset structure so that the second limit member can automatically reset under the action of the rebound force, making the fixing device more automated and ensuring the continuity of the closing process of the locking structure.

[0031] 3. The present invention provides a sweeper fixing device, in which the movable pressure plate can increase the contact surface, effectively preventing the second limit member from being crushed when the sweeper's travel wheel directly presses against it, thereby ensuring the reliability of the device and reducing the pressure of the sweeper on the fixing device as a whole. Moreover, the top wall of the movable pressure plate can be configured as an inclined surface, so that when the travel wheel presses over the inclined surface, the opening of the locking structure has a larger adjustable range.

[0032] 4. The present invention provides a sweeper docking station, which ensures overall stability when the sweeper is docked at the docking station by setting the above-mentioned sweeper fixing device, and is not affected by strong winds. In addition, the locking state of the fixing device can be adjusted according to the weight and movement of the sweeper, making it very convenient for the sweeper to enter and exit the docking station.

[0044] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0045] In one embodiment, referring to Figure 1 of the specification, a sweeper fixing device provided by the present invention is explained. The sweeper fixing device provided by the present invention can effectively fix the sweeper 4 to prevent the sweeper 4 from being blown off in severe wind conditions. At the same time, it can also unlock the sweeper 4 in time, ensuring the normal use and life of the sweeper 4.

[0046] Referring to Figures 1 to 3 of the specification, a sweeper fixing device provided by the present invention is arranged on a bracket 3 for docking a sweeper 4, and includes a first limit member 1 and a second limit member 2. The first limit member 1 is fixed on the bracket 3, and a fixing ring 41 is provided on the sweeper 4. The first limit member 1 passes over part of the fixing ring 41 during the process of the sweeper 4 docking on the bracket 3; the second limit member 2 is rotatably connected to the bracket 3, and one end of the second limit member 2 is provided with an adjustment part 21 provided on the docking path of the sweeper 4, and the other end of the second limit member 2 is a movable end and is close to the first limit member 1, and the movable end can form an enclosed area with the first limit member 1.

[0047] In the first state, when the sweeper 4 is docked at the bracket 3 or moving out of the bracket 3, the adjusting part 21 moves downward due to pressure, thereby driving the movable end to move in the direction away from the first limit member 1, and the enclosed area is opened; in the second state, after the sweeper 4 is docked at the bracket 3, the adjusting part 21 is not pressed, and the movable end moves toward the direction of the first limit member 1 through the rebound force of the reset structure, forming an enclosed area passing through part of the fixed ring 41, thereby locking the sweeper 4.

[0048] It should be noted that the first limit member 1 and the second limit member 2 can adjust the locking or opening state through the force of the adjustment part 21, making the fixation of the sweeper 4 more convenient and flexible, without the need to use electric drive to drive such a fixing device, more energy-saving and less susceptible to environmental factors.

[0049] The sweeper fixing device in this embodiment is very suitable for the photovoltaic market. Since photovoltaic sweepers generally work outdoors and are mostly used in large photovoltaic power stations, photovoltaic greenhouses or industrial parks, which are easily affected by strong winds, it is crucial to fix the photovoltaic sweeper. The sweeper fixing device in this embodiment does not require electric drive or terminal control, but uses the weight of the sweeper to achieve locking or unlocking, which reduces the interference of external factors to a certain extent and ensures the stable docking of the sweeper.

[0050] Specifically, in the initial state, the ends of the first limit member 1 and the second limit member 2 are interlocked to form the above-mentioned enclosed area, which can be used to lock the sweeper 4; when the sweeper 4 generates pressure on the adjustment part 21, the adjustment part 21 will move in the direction of pressure, and the second limit member 2 will also shift to one side at the same time, and rotate relative to the first limit member 1, so that the interlocked part is opened. It can also be understood that an opening is generated in the enclosed area, and the locking state of the sweeper 4 is released, and relative movement can be performed through the opening.

[0051] In one embodiment, the reset structure is respectively connected to the bracket 3 and the second limiter 2 to provide a rebound force, and when the adjustment portion 21 is not compressed, the movable end moves toward the first limiter 1 due to the rebound force to form an enclosed area.

[0052] The reset structure can provide a rebound force, so that the relative movement of the adjustment part 21 is faster under the drive of the rebound force, so that the movable end can synchronously approach the first limit member 1 to adjust the opening and closing of the enclosed area; in addition, the second limit member 2 is connected to the bracket 3 through the reset structure, which can also make the structures more firm and more reliable.

[0053] In addition, the reset structure can be set as a spring 5 and a spring receiving groove opened on the bracket 3. One end of the spring 5 is fixed in the spring receiving groove, and the other end is connected to the second limit member 2. Setting the spring 5 in the spring receiving groove can play a certain shielding role. At the same time, the spring 5 will be more stable and not prone to displacement.

[0054] In another embodiment, the reset structure includes a spring 5 and a connecting plate 51 , wherein the two free ends of the spring 5 are respectively connected to the connecting plate 51 and a side of the second limiting member 2 close to the adjustment portion 21 , and the connecting plate 51 is fixedly connected to the bracket 3 .

[0055] It should be noted that the spring 5 has excellent ductility and resilience, and can adapt to most scenarios, and the connecting plate 51 can provide a connection space so that the relative connection position of the spring 5 can be adjusted to adapt to the sizes and parameters of other related parts.

[0056] Among them, referring to Figure 3 of the specification, when the spring 5 is stretched under force, the second limit member 2 will be displaced synchronously. Since the second limit member 2 and the first limit member 1 are rotationally connected, the enclosed area between the two is opened to a corresponding angle; when the spring 5 is not under force, due to its own characteristics, the second limit member 2 rebounds and the enclosed area is closed again, thereby realizing the locking and unlocking of the sweeper 4 by the fixing device.

[0057] In another embodiment, referring to Figure 2 of the specification, a sleeve 101 is provided on the first limiting member 1, and the second limiting member 2 is rotatably connected to the sleeve 101 through a rotating shaft 102, so that the second limiting member 2 can rotate relative to the first limiting member 1 to adjust the opening or closing of the enclosed area.

[0058] It is worth mentioning that, through the cooperation of the sleeve 101 and the rotating shaft 102, the interval between the first limit member 1 and the second limit member 2 is smaller, the overall fixed structure is tighter, and the occupied space is smaller, which can greatly improve the space utilization rate of the bracket.

[0059] On the basis of the above embodiment, referring to Figure 4 of the specification, the first limiting member 1 passes through the radial direction of the sleeve 101, and the sleeve 101 forms a partial wrap relative to the first limiting member 1; and the second limiting member 2 passes through the radial direction of the rotating shaft 102, and the movable end and the adjustment part 21 set on the second limiting member 2 are distinguished on both sides of the rotating shaft 102.

[0060] It can be understood that the sleeve 101 is provided with an assembly hole, so that part of the rotating shaft 102 can be inserted into the assembly hole to realize the rotation of the rotating shaft 102. In this embodiment, the rotating shaft 102 is configured as a stepped shaft, and the small diameter portion of the stepped shaft is inserted into the assembly hole to realize rotation, and the large diameter portion is penetrated by the second limit member 2, thereby realizing the fixation of the second limit member 2.

[0061] More preferably, the diameters of the large diameter portion and the sleeve 101 are the same, forming a smooth and continuous rotor structure, which improves the aesthetics to a certain extent. However, in some cases, the rotating shaft 102 may not be configured as a stepped shaft. In this case, rotation can also be achieved and should also be included in the scope of protection of the present invention.

[0062] In addition, an elastic snap ring can be installed on the outer periphery of the sleeve 101 and the rotating shaft 102 to ensure the tightness of the connection between the two. At the same time, the elastic snap ring can also use waterproof material to prevent water or dust and other substances from entering the joint between the sleeve 101 and the rotating shaft 102, thereby playing a protective role.

[0063] Specifically, annular grooves can be set on the outer periphery of the sleeve 101 and the rotating shaft 102, and two corresponding guide belts can be set on the inner periphery of the elastic retaining ring, so that the guide belts and the annular grooves correspond to each other, which not only provides a guiding function to make the rotation smoother, but also prevents the sleeve 101 and the rotating shaft 102 from offsetting.

[0064] In one embodiment, the first limit member 1 and the second limit member 2 are both configured as connecting rods having several bent sections, wherein when the sweeper 4 is docked on the bracket 3, the opening direction formed by the several bent sections of the second limit member 2 is toward the sweeper 4; and at least one bent section of the second limit member 2 is located on the docking path of the sweeper 4.

[0065] It should be noted that the connecting rod with a bending section is a better implementation form. Through several clever bending sections, it is possible to simultaneously achieve the generation of an enclosed area between the first limit member 1 and the second limit member 2, and it is also possible to adjust the corresponding state of the adjustment part 21. There is no need for multiple components to be used in combination, which reduces the number of parts and the labor cost during assembly.

[0066] In addition to the form of the bending segment in the accompanying drawings, the contour shapes of the first limiting member 1 and the second limiting member 2 can also be set to smooth arcs, which are not listed here one by one. In this embodiment, due to the difficulty of production and the ease of installation, the contour shapes of the limiting members are basically continuous bends composed of multiple straight lines.

[0067] In addition, the bending section of the second limit member 2 located on the parking path of the sweeper 4 also corresponds to the adjustment part 21. When the sweeper 4 is passing through this bending section, the adjustment part 21 can be displaced, thereby creating an opening between the first limit member 1 and the second limit member 2, and the fixing ring 41 enters between the two limit members through the opening. After the sweeper 4 passes through this bending section, the opening is transformed into a closed state so that the fixing ring 41 is locked.

[0068] In one embodiment, referring to Figures 2 and 3 of the specification, a movable pressure plate 6 is further provided at the end of the adjusting portion 21, and one side of the movable pressure plate 6 abuts against the bracket 3 fixedly connected to the connecting plate 51, wherein the top wall of the movable pressure plate 6 cooperates with the walking wheel 42 of the sweeper 4, so that when the walking wheel 42 presses down the movable pressure plate 6, the adjusting portion 21 is pressed down synchronously to make the movable end of the second limiting member 2 move away from the first limiting member, so that an opening is generated in the enclosed area.

[0069] The movable pressure plate 6 here increases the contact area between the adjustment part 21 and the travel wheel 42 of the sweeper 4, and makes it difficult for the adjustment part 21 to be damaged by long-term pressure during operation, making the device more reliable and more stable.

[0070] Specifically, when the walking wheel 42 of the sweeper 4 passes through the movable pressure plate 6, the movable pressure plate 6 moves downward, causing the second limit member 2 to move synchronously, and the fixed ring 41 also synchronously enters the opening between the first limit member 1 and the second limit member 2. After the walking wheel 42 passes through the movable pressure plate 6, the opening is closed and the fixed ring 41 is locked.

[0071] In another embodiment, based on the above embodiment, the movable pressure plate 6 is provided with two inclined surfaces, which are divided into an entry surface 61 and an exit surface 62. When the running wheel 42 presses down on the entry surface 61 or the exit surface 62, the enclosed area formed by the movable end and the first stop member 1 is opened, and the sweeper 4 can subsequently dock or exit the docking position. In addition, the entry surface 61 and the exit surface 62 intersect, and the horizontal position of the intersection line is higher than the horizontal position of the bracket 3 to which the connecting plate 51 is fixedly connected.

[0072] The entry surface 61 and the exit surface 62 here are two inclined surfaces distinguished according to the docking path of the sweeper 4. The surface that is first pressed down when the sweeper 4 enters the docking station is the entry surface 61, and the surface that is first pressed down when the sweeper 4 exits the docking station is the exit surface 62.

[0073] It should be noted that the top wall of the movable pressure plate 6 is set in the form of an inclined surface, which can increase the effective displacement length of the adjustment part 21 to a certain extent, so that the opening degree of the enclosed area can be adjusted accordingly. It can be understood that the larger the inclination angle of the inclined surface, the higher the horizontal position of the intersection line. When the walking wheel 42 passes over the movable pressure plate 6, the displacement of the movable pressure plate 6 in the vertical direction will be greater. During this process, the adjustment part 21 will synchronously drive the second limit member 2 to move, thereby affecting the opening degree of the enclosed area.

[0074] It is also worth mentioning that setting it as an inclined surface can also facilitate the travel of the sweeper 4. If the movable pressure plate 6 is only set on a flat surface, the sweeper 4 will easily cause bumps without the guidance of the slope, resulting in poor subsequent fixing effect.

[0075] In other embodiments, the distance between the corresponding components can also be set, such as the length of the two limit members, the setting position of the movable pressure plate 6 and the size of the fixing ring 41, etc. This setting avoids the situation where the opening is closed when the walking wheel 42 is not in place or the opening is not opened when the walking wheel 42 is in place.

[0076] In addition, when the sweeper 4 has multiple rows of running wheels 42, the purpose of adjusting the opening can also be achieved by using the front wheel trigger, the middle wheel trigger or the rear wheel trigger.

[0077] In one embodiment, based on the above embodiment, the end portion away from the first limit member 1 and fixed to the bracket 3 is configured as a fixed hook 12, and the movable end of the second limit member 2 and the end portion cooperating with the fixed hook 12 are set as a movable hook 22; the highest point of the fixed hook 12 is horizontally positioned higher than the fixed ring 41; in the first state, the end spaces of the fixed hook 12 and the movable hook 22 abut against each other to form an enclosed area for locking the fixed ring 41, and in the second state, the movable hook 22 moves in a direction away from the fixed hook 12, and the enclosed area opens so that the fixed ring 41 can pass through the opening created by the enclosed area.

[0078] Among them, the fixed hook 12 and the movable hook 22 both have a certain curvature, which can better fit the edge of the fixed ring 41, and the outline is more rounded, and it is not easy to bump or scratch other parts.

[0079] It should be noted that the horizontal position of the fixed hook 12 is higher than the fixed ring 41, so that when the sweeper 4 moves, the fixed hook 12 will not block the fixed ring 41. Therefore, the fixed hook 12 does not need to be moved, and only the movable hook 22 needs to be moved to adjust the opening.

[0080] In one embodiment, referring to FIG1 of the specification, according to another aspect of the present invention, the present invention further provides a sweeper docking station, comprising a bracket 3 for supporting and docking a sweeper 4; and at least one of the above-mentioned sweeper fixing devices, which is correspondingly arranged on the bracket 3.

[0081] It should be noted that the sweeper fixing device can be set according to factors such as the size and structure of the sweeper 4, and the sweeper 4 can be fixed in multiple places by utilizing the matching relationship between multiple sets of first limit members 1 and second limit members 2, which can ensure that the sweeper 4 will not be blown down or over in severe windy environments.

[0082] In one embodiment, the sweeper docking station is provided with a barrier frame 7, which is composed of several steel frames to match the semi-enclosed area of ​​the sweeper 4, so that the sweeper 4 is located in the semi-enclosed area when docked, thereby improving safety and reliability.

[0083] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
