Description

Technical Field

[0001] This invention relates to the field of road cleaning equipment technology, specifically a small, multi-functional road cleaning vehicle. Background Technology

[0002] Unmanned sweeping vehicles are sweeping vehicles that can automatically avoid obstacles, drive autonomously, turn around automatically, pass through traffic lights automatically, and park automatically. With the rapid development of society and the continuous improvement of technology, intelligent devices have flourished in the application of the Internet. With the continuous development and progress of autonomous driving technology, unmanned sweeping vehicles have emerged.

[0003] In existing road cleaning equipment, such as the road cleaning vehicle with application number CN202322123037.0, a vehicle body is included, and the vehicle body is equipped with a dust collection box, a sweeping mechanism, and a lifting mechanism. The dust collection box is equipped with a dust suction mechanism and a ventilation mechanism. This utility model can utilize the operation of a first motor to drive two first rotating shafts to rotate together, thereby causing the first fan blade to deliver air into the dust collection box, creating negative pressure in the suction pipe, which can realize the extraction of dust from the ground at the bottom of the suction pipe. Then, the operation of a second motor drives two second rotating shafts to rotate together, thereby realizing the rotation of two second fan blades to extract air from the dust collection box, and retaining the dust in the dust collection box through the filter screen, thus ensuring the air circulation effect in the dust collection box. At the same time, the operation of a third motor drives a third rotating shaft to rotate, further driving the third fan blade and the sweeping plate to rotate, so that the sweeping plate sweeps the dust on the ground.

[0004] However, traditional road cleaning vehicles have relatively limited functions and rely on fixed power supply methods for energy, which not only has high operating costs but also lacks environmental friendliness. At the same time, the installation structure of solar power-related components on cleaning vehicles is generally not flexible enough, making it difficult to adjust the angle of solar panels according to actual sunlight conditions, resulting in low solar energy collection efficiency.

[0005] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0006] To address the aforementioned issues, an innovative design was implemented based on the existing road cleaning vehicle. Summary of the Invention

[0007] The purpose of this invention is to provide a small, multi-functional road cleaning vehicle to solve the problems mentioned in the background art, such as the relatively simple functions of traditional road cleaning vehicles, their reliance on fixed power supply, high operating costs, and lack of environmental friendliness; at the same time, the solar power supply components on the cleaning vehicle generally suffer from inflexible installation structures, making it difficult to adjust the angle of the solar panels according to actual sunlight conditions, resulting in low solar energy collection efficiency.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A small, multi-functional road cleaning vehicle includes a vehicle body and a control panel. The control panel is fixedly mounted on the outer side of the vehicle body. A receiving groove is formed on the upper surface of the vehicle body, and a first sliding groove is formed on the bottom surface of the receiving groove. An outer frame is rotatably connected to the middle of the receiving groove. An embedding groove is formed on the outer surface of the outer frame, and a frame is detachably connected to the inside of the embedding groove by bolts. A solar panel is embedded in the middle of the frame. A motor is installed inside the vehicle body. A lead screw is movably connected to the output end of the motor. A slider is threaded to the outer surface of the lead screw. A fifth mounting seat is fixed on the upper surface of the slider. A support rod is rotatably connected to the middle of the fifth mounting seat. A fixing block is fixed to the bottom of the outer frame. A sixth mounting seat is fixed to the bottom of the fixing block, and the other end of the support rod is rotatably connected to the middle of the sixth mounting seat.

[0009] Using the above technical solution, the motor drives the lead screw to rotate, causing the slider to move along the first slide groove. The slider drives the outer frame to rotate around one end of the receiving groove through the support rod, realizing the angle adjustment of the outer frame and the solar panel. The angle of the solar panel can be flexibly adjusted according to the sun's position at different times, so as to maximize the reception of sunlight, improve the solar energy utilization efficiency, and provide more power support for the cleaning vehicle.

[0010] Preferably, the front end of the vehicle body is rotatably connected to a rotating seat via a rotating shaft, a support rod is fixed to the outer side of the rotating seat, a first mounting seat is fixed to the front end face of the vehicle body, a first electric push rod is rotatably connected to the middle of the first mounting seat, a second mounting seat is fixed to the inner side of the support rod, and the output end of the first electric push rod is rotatably connected to the middle of the second mounting seat.

[0011] Using the above technical solution, when the first electric push rod extends or retracts, its output end drives the second mounting base, which is rotatably connected to it, to move. Since the second mounting base is fixed on the support rod, it pushes the support rod to rotate around the rotating shaft on the rotating seat, which can flexibly adjust the angle of the support rod. In this way, the working position and angle of the relevant cleaning components installed on the support rod can be adjusted according to the actual cleaning needs, thereby improving the cleaning effect.

[0012] Preferably, a connecting rod is rotatably connected to the front end of the support rod, a third mounting seat is fixed to the inner side of the support rod, a second electric push rod is rotatably connected to the middle of the third mounting seat, a fourth mounting seat is fixed to the inner side of the connecting rod, and the output end of the second electric push rod is rotatably connected to the middle of the fourth mounting seat.

[0013] Using the above technical solution, the second electric push rod extends and retracts, and its output end drives the fourth mounting base to move. Since the fourth mounting base is fixed on the connecting rod, the connecting rod rotates around the rotation connection point with the support rod. The angle and position of the connecting rod and the components connected to its front end can be flexibly adjusted to adapt to different road conditions and cleaning needs, thereby enhancing the targeting and effectiveness of cleaning.

[0014] Preferably, a main cleaning brush is installed at the front end of the connecting rod, and two sets of main cleaning brushes are symmetrically installed along the front end of the vehicle body, while two sets of auxiliary cleaning brushes are symmetrically installed at the bottom of the middle section of the vehicle body.

[0015] By adopting the above technical solution, the vehicle body moves along with the fixed installation structure of the front end of the connecting rod and the bottom of the middle section of the sweeping brush. The two main sweeping brushes move with the connecting rod, and the two auxiliary sweeping brushes move with the vehicle body. The sweeping action is achieved by the contact friction between the brush bristles and the road surface. The main sweeping brushes and auxiliary sweeping brushes work together to expand the sweeping range. The main sweeping brushes focus on cleaning the area in front of the vehicle body, while the auxiliary sweeping brushes clean the area below the middle section of the vehicle body, thereby improving the comprehensiveness and efficiency of road surface cleaning.

[0016] Preferably, the vehicle body has a water storage tank inside, and a water inlet connected to the water storage tank is provided at the rear end of the vehicle body. A water pump is provided at the bottom of the water storage tank, and a water delivery pipe is connected to the middle of the water pump. The other end of the water delivery pipe extends into the water storage tank, and a water collection pipe is connected to the other end of the water delivery pipe. Several nozzles are connected to the bottom of the water collection pipe.

[0017] Using the above technical solution, the water pump draws water from the water storage tank, delivers it to the water collection pipe through the water supply pipe, and then sprays the water out in a mist form from multiple nozzles at the bottom of the water collection pipe. This realizes the delivery and spraying of water from the water storage tank to the outside of the vehicle body. When cleaning the road, the water sprayed from the nozzles can moisten the road surface, suppress dust, and also assist the main sweeping brush and the auxiliary sweeping brush in washing away and collecting dust and debris, improving the cleaning effect and improving the working environment.

[0018] Preferably, the nozzles are arranged in seven groups horizontally along the bottom of the water collection pipe, and the spraying end of the nozzles faces the side of the two groups of auxiliary cleaning brushes.

[0019] Using the above technical solution, the water pump pumps water from the storage tank into the collection pipe through the water delivery pipe. Since the seven sets of nozzles are arranged horizontally at the bottom of the collection pipe and the spray ends are all facing the side of the auxiliary sweeping brush, the water will be sprayed from each nozzle at a certain angle and range into the working area of ​​the auxiliary sweeping brush under pressure. During the cleaning operation, the water sprayed from the nozzles can be accurately sprayed onto the working area of ​​the auxiliary sweeping brush, pre-wetting the road dust, enhancing the cleaning effect of the auxiliary sweeping brush, and effectively suppressing the dust generated during the cleaning process to avoid secondary pollution.

[0020] Preferably, the interior of the vehicle body has a placement slot, the bottom of the placement slot is fixedly installed with a slide rail, the placement slot contains a battery assembly, and the bottom of the battery assembly has a second slide groove that matches the slide rail.

[0021] By adopting the above technical solution, a slide rail is set at the bottom of the placement slot, and a second slide groove adapted to it is opened at the bottom of the battery pack. The sliding fit structure between the slide rail and the second slide groove allows the battery pack to slide smoothly along the slide rail in the placement slot, which facilitates the installation and removal of the battery pack in the vehicle body, and makes it easier to perform operations such as battery maintenance, replacement or charging. At the same time, the cooperation between the slide rail and the slide groove can also ensure the stability of the battery pack during vehicle operation.

[0022] Preferably, the rear end of the battery assembly is detachably connected to a heat dissipation fin by bolts, and a cooling fan is fixedly installed on the outer side of the vehicle body and on one side of the heat dissipation fin.

[0023] Using the above technical solution, the battery module generates heat during operation, which is conducted to the heat dissipation fins connected to it. The heat dissipation fins increase the heat dissipation area and accelerate heat dissipation. At the same time, the cooling fan runs to create airflow, which quickly blows away the hot air around the heat dissipation fins, promotes the exchange of hot and cold air, effectively reduces the temperature of the battery module during operation, prevents the battery performance from being affected by excessive temperature, shortens the battery life, or even causes safety hazards, and ensures the stable and reliable operation of the battery module.

[0024] Preferably, an inspection door is rotatably connected to the outer side of the vehicle body and on the other side of the placement slot via a hinge, and the inspection door is electrically connected to the vehicle body via an electromagnetic lock.

[0025] The above technical solution utilizes a hinge to achieve a rotating connection between the maintenance door and the vehicle body, allowing for flexible opening and closing. When the electromagnetic lock is energized, it generates magnetic force to firmly lock the maintenance door to the vehicle body. When the power is off, the magnetic force disappears, and the maintenance door can be opened. The maintenance door facilitates the inspection, maintenance, and replacement of components such as battery packs stored in slots inside the vehicle body. The electromagnetic lock also enhances the safety of the vehicle body, preventing the maintenance door from being accidentally opened while the vehicle is in motion, thus ensuring the safety of equipment and personnel.

[0026] Compared with the prior art, the beneficial effects of the present invention are: this small multi-functional road cleaning vehicle, 1. The motor drives the lead screw to rotate, causing the slider to move along the first slide groove. This, in turn, drives the outer frame to rotate via the support rod. This allows for flexible adjustment of the angle of the solar panels on the outer frame, maximizing their ability to receive sunlight based on the sun's position at different times. This improves solar energy conversion efficiency, providing more power and extending the range of the cleaning vehicle. At the same time, the embedded slot of the outer frame is detachably connected to the frame via bolts, facilitating the installation, replacement, and maintenance of the solar panels. This enhances the practicality and environmental friendliness of the cleaning vehicle, while reducing operating costs and maintenance difficulty. 2. Through the cooperation of the rotating seat at the front of the vehicle body, the support rod and the first electric push rod, as well as the linkage of the support rod, the connecting rod and the second electric push rod, the height and angle of the main sweeping brush can be flexibly and precisely adjusted so that it closely fits the road surface in different conditions, effectively improving the sweeping effect; two sets of main sweeping brushes are symmetrically arranged at the front of the vehicle body, and together with two sets of auxiliary sweeping brushes symmetrically arranged at the bottom of the middle section of the vehicle body, the cleaning range can be expanded to achieve all-round and dead-angle sweeping of the road surface, meeting diverse road cleaning needs, and is especially suitable for cleaning roads with complex terrain and different levels of pollution. 3. A water storage tank with a rear water inlet is installed inside the vehicle body to facilitate the replenishment of cleaning water at any time and ensure the continuous operation of cleaning. A water pump is installed at the bottom of the water storage tank, and water is delivered to the collection pipe through the water supply pipe. Then, seven sets of nozzles arranged horizontally at the bottom of the collection pipe spray water towards the auxiliary sweeping brush. This can effectively wet the road surface before sweeping, enhance the adhesion of dust, and make the auxiliary sweeping brush more efficient in cleaning dust and debris. At the same time, it suppresses the dust generated during sweeping, avoids secondary pollution, greatly improves the quality and effect of road cleaning, and improves the working environment. 4. The vehicle body features placement slots and sliding rails, which, together with the second sliding groove at the bottom of the battery pack, facilitate quick installation and removal of the battery pack, making daily maintenance and replacement easier. The removable heat dissipation fins at the rear of the battery pack increase the heat dissipation area, and combined with the cooling fan on one side of the vehicle body, effectively improve the heat dissipation efficiency of the battery pack and extend its service life. The maintenance door on the other side of the vehicle body, connected by a hinge and controlled by an electromagnetic lock, ensures internal safety during equipment operation and allows for easy opening when maintenance is needed, providing convenience for the inspection and maintenance of internal components such as the battery pack and improving the overall user experience.
