Description
Technical Field
[0001] This utility model relates to the field of sweeper technology, and in particular to a sweeper with adjustable internal volume. Background Technology
[0002] Currently, the water tanks and garbage bins of most sweepers on the market have a fixed initial structure, which cannot be adjusted later. This makes the overall structure of the sweeper fixed, and it is impossible to flexibly adjust the volume of the water tank and garbage bin according to the actual working conditions during operation.
[0003] In actual cleaning operations, it often happens that the water runs out but the trash can still has a lot of space, or the trash can is full but there is still water left, resulting in resource waste and low operational efficiency. At the same time, the fixed structure also limits the adaptability of the sweeper to cleaning tasks of different scales and types, making it difficult to meet the increasingly diverse needs of sanitation operations. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a sweeper with adjustable internal volume, thereby solving the problem that the fixed internal structure of existing sweepers makes them unable to adapt to sweeping tasks of different scales and types.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sweeper with adjustable internal volume, comprising: The vehicle body has a mounting box that is mounted on the vehicle body and has an internal cavity for accommodating it. A flexible partition is disposed within the receiving cavity, dividing the receiving cavity into a first cavity and a second cavity that are independent of each other; An adjustment mechanism is located on the upper and lower sides of the flexible partition. The adjustment mechanism includes a sealing shell, a buffer assembly, and a telescopic assembly. Two sets of buffer assemblies are provided and located at both ends of the sealing shell. The buffer assembly includes a telescopic rod, a buffer spring, and a sliding plate. The two ends of the telescopic rod are connected to the side wall of the sealing shell and the sliding plate. The buffer spring is sleeved on the telescopic rod, and the sliding plate reciprocates along the sealing shell. The telescopic assembly is located between the sliding plates, and the driving end of the telescopic assembly is rotatably connected to the flexible partition. Under the action of the force transmitted by the flexible partition, the buffer assembly drives the overall displacement of the telescopic assembly, and the telescopic assembly actively drives one end of the flexible partition to reciprocate and extend.
[0006] In one embodiment, the telescopic assembly includes a support plate, an electric push rod, and a connecting rod. The support plate is disposed between sliding plates, the fixed end of the electric push rod is disposed on the support plate, the output end of the electric push rod is hinged to the connecting rod, and the connecting rod passes through an adjustment through hole on the support plate and is connected to a flexible spacer.
[0007] In one embodiment, a self-aligning bearing is sleeved on the connecting rod, and the self-aligning bearing is disposed in the adjustment through hole.
[0008] In one embodiment, the end of the connecting rod near the self-aligning bearing has a sliding section with a diameter smaller than that of the other parts. The sliding section is embedded in the self-aligning bearing and is slidably connected to the self-aligning bearing.
[0009] In one embodiment, the end of the connecting rod away from the electric push rod is hinged to the flexible spacer via a pin, which is embedded in the flexible spacer.
[0010] In one embodiment, the sealing housing has a movable opening, through which a flexible spacer extends into the sealing housing.
[0011] In one embodiment, an adjustment plate is provided on the side of the sliding plate near the movable opening. The adjustment plate slides together with the sliding plate along the sealing housing to block the movable opening.
[0012] In one embodiment, a barrier layer is provided on the side of the support plate near the movable opening.
[0013] In one embodiment, the flexible spacer is made of high-strength rubber or flexible plastic.
[0014] In one embodiment, a liquid level sensor is provided in the first cavity, and a distance sensor is provided on the top of the second cavity. The liquid level sensor and the distance sensor are electrically connected to the adjustment mechanism.
[0015] The beneficial effects of this utility model are as follows: The water tank and garbage bin of a conventional sweeper are fixed structures, and their specifications cannot be changed after production. Under different working conditions, one bin may be insufficient while the other is excessive. As a result, the sweeper has to be returned to the factory multiple times to replenish water or empty garbage, which seriously affects work efficiency.
[0016] Therefore, this utility model uses a flexible partition to divide the accommodating cavity of the mounting box into a first cavity and a second cavity. Through the elastic deformation of the flexible partition, the relative volume of the first cavity and the second cavity changes, thereby making the first cavity or the second cavity have a larger volume than the initial state.
[0017] However, if a flexible partition is used for passive adjustment, the impact force when filling with a large amount of water or absorbing waste may exert excessive force on the flexible partition, exceeding its elastic range and causing localized deformation. Therefore, this invention provides adjustment mechanisms at the top and bottom of the receiving cavity. The buffer components within these mechanisms adjust the overall position of the flexible partition within the cavity, thereby buffering some of the forces acting on the flexible partition and reducing its deformation.
[0018] Meanwhile, this utility model uses an actively controllable telescopic component to adjust the position of one or both sides of the flexible partition, thereby adjusting the angle and tension of the flexible partition. This allows the flexible partition to be actively adjusted during the cleaning process, thereby regulating the internal pressure of the first and second cavities. This facilitates the sweeper to spray water for cleaning or suck up garbage, further improving the overall adaptability to different working conditions. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0024] Please refer to Figures 1 to 5 A sweeper with adjustable internal volume, comprising: The vehicle body 1 has a mounting box 2, which is mounted on the vehicle body 1, and the mounting box 2 has an internal cavity 21. A flexible partition 22 is disposed in the receiving cavity 21, dividing the receiving cavity 21 into a first cavity 211 and a second cavity 212 that are independent of each other. Adjustment mechanism 3 is disposed on the upper and lower sides of flexible partition 22. Adjustment mechanism 3 includes sealing housing 31, buffer assembly 32 and telescopic assembly 33. Two sets of buffer assembly 32 are provided and located at both ends of sealing housing 31. Buffer assembly 32 includes telescopic rod 321, buffer spring 322 and sliding plate 323. The two ends of telescopic rod 321 are connected to the side wall of sealing housing 31 and sliding plate 323. Buffer spring 322 is sleeved on telescopic rod 321. Sliding plate 323 moves back and forth along sealing housing 31. Telescopic assembly 33 is disposed between sliding plates 323. The driving end of telescopic assembly 33 is rotatably connected to flexible partition 22. Under the action of the force transmitted by flexible partition 22, buffer assembly 32 drives telescopic assembly 33 to move as a whole. Telescopic assembly 33 actively drives one end of flexible partition 22 to reciprocate and extend.
[0025] In this embodiment, the telescopic component 33 includes a support plate 331, an electric push rod 332, and a connecting rod 333. The support plate 331 is disposed between sliding plates 323. The fixed end of the electric push rod 332 is disposed on the support plate 331, and the output end of the electric push rod 332 is hinged to the connecting rod 333. The connecting rod 333 passes through an adjustment through hole on the support plate 331 and connects to the flexible spacer 22. After the support plate 331 is set, the telescopic component 33 is clamped between two sets of buffer components 32 with a fixed overall width. The force on the flexible spacer 22 is transmitted to the buffer components 32 through the telescopic component 33. The buffer components 32 on both sides push and pull the telescopic component 33, thereby providing sufficient buffering.
[0026] Preferably, the electric push rod 332 is electrically connected to the control module of the sweeper. Those skilled in the art can set the corresponding wiring according to the actual situation, without making specific limitations. Furthermore, each side of the adjustment mechanism 3 has two sets of electric push rods 332.
[0027] After the connecting rod 333 is installed, the operation of the electric push rod 332 will cause the connecting rod 333 to tilt and shift. With prolonged use, wear may occur between the connecting rod 333 and the adjusting through hole, potentially leading to problems such as the connecting rod 333 jamming. Therefore, a self-aligning bearing 334 is fitted onto the connecting rod 333, and the self-aligning bearing 334 is located within the adjusting through hole. This arrangement allows the connecting rod 333 to smoothly change angles, thereby improving the overall service life of the structure.
[0028] In this embodiment, the end of the connecting rod 333 near the self-aligning bearing 334 has a sliding section 3331. The diameter of the sliding section 3331 is smaller than the diameter of the other parts. The sliding section 3331 is embedded in the self-aligning bearing 334 and slidably connected to the self-aligning bearing 334. That is, the part of the connecting rod 333 located in the self-aligning bearing 334 is a contraction section, which allows the connecting rod 333 to slide on the self-aligning bearing 334, avoiding jamming, and adapting to the action of the electric push rod 332 to tighten or loosen the flexible spacer 22, further improving the overall adjustability of the mechanism.
[0029] In this embodiment, the end of the connecting rod 333 furthest from the electric push rod 332 is hinged to the flexible partition plate 22 via a pin 335, which is embedded within the flexible partition plate 22. This embedded pin 335 structure allows the connecting rod 333 to connect more effectively to the flexible partition plate 22, preventing problems such as excessive local stress on the flexible partition plate 22 leading to localized breakage, thereby ensuring the overall stability and safety of the structure.
[0030] More preferably, the flexible partition 22 has a structure with a chain plate embedded in the center and covered with a high-strength rubber layer or a flexible plastic layer on the outside, and the pin 335 is connected to the chain plate. This ensures the overall strength of the flexible partition 22 while providing barrier and deformation capabilities, preventing the flexible partition 22 from being punctured by garbage or other external objects, and ensuring the independence of the first cavity 211 and the second cavity 212. In this embodiment, the sealing shell 31 has a movable opening, through which the flexible partition 22 extends into the sealing shell 31.
[0031] In this embodiment, an adjustment plate 324 is provided on the side of the sliding plate 323 near the movable opening. The adjustment plate 324 slides along the sealing housing 31 with the sliding plate 323 to block the movable opening. After the adjustment plate 324 is connected to the sliding plate 323, the whole is L-shaped. The adjustment plate 324 abuts against the sealing housing 31 with the movable opening and slides along the sealing housing 31. This arrangement allows the adjustment plates 324 on both sides to move with the movement of the buffer assembly 32, blocking part of the movable opening and preventing the movable opening from being too large, thereby improving the stability and service life of the structure.
[0032] Furthermore, a plastic film is provided on the movable opening. The plastic film seals and blocks the movable opening without interfering with the rotation of the connecting rod 333, thus ensuring the sealing of the adjustment mechanism 3.
[0033] In this embodiment, a barrier layer 34 is provided on the side of the support plate 331 near the movable opening. Specifically, the barrier layer 34 is made of sponge or airbag. The barrier layer 34 is sleeved on the connecting rod 333 and clamps the flexible spacer 22. When the connecting rod 333 moves, it causes the barrier layer 34 to deform, thereby blocking the garbage without interfering with the movement of the connecting rod 333, and preventing the garbage from entering the adjustment mechanism 3 and interfering with the operation of the adjustment mechanism 3.
[0034] In this embodiment, the flexible spacer 22 is made of high-strength rubber or flexible plastic.
[0035] In this embodiment, a liquid level sensor is installed inside the first cavity 211, and a distance sensor is installed on the top of the second cavity 212. The liquid level sensor and the distance sensor are electrically connected to the adjustment mechanism 3. The liquid level sensor is used to detect the liquid level in the first cavity 211, and the distance sensor is used to detect the height of the waste in the second cavity 212, enabling operators to monitor the water and waste volume in real time, thereby enabling proactive control and improving overall adjustability.

These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
