Description

Technical Field

[0001] This invention relates to the field of multi-purpose vehicle technology, specifically a multi-functional mobile commercial vehicle. Background Technology

[0002] In the business activities and outdoor services sector, mobile commercial vehicles are widely used in outdoor exhibitions, temporary service stations, and emergency support scenarios due to their advantages of flexible mobility and integrated functions. However, existing mobile commercial vehicles still have many technical shortcomings in actual use, making it difficult to meet the needs of efficient, stable, and multifunctional use.

[0003] Firstly, the booth construction is inefficient and lacks stability. Existing mobile commercial vehicles, when needing to expand their operating space to build booths, mostly rely on detachable support components. Operators must assemble the supports and fix the panels one by one, which is not only cumbersome and time-consuming but also requires carrying additional tools, making it difficult to quickly respond to temporary construction needs. Some commercial vehicles with extended side panels only use simple bolts or pins to fix the panels to the ground, achieving only unidirectional anchoring. In soft soil or light wind conditions, the side panels are prone to swaying and tipping, failing to guarantee booth safety and limiting their application in complex outdoor scenarios.

[0004] Secondly, the cleaning of photovoltaic panels is energy-intensive and has limited effectiveness. To improve range, some mobile commercial vehicles are equipped with photovoltaic panels, but existing methods for cleaning these panels have significant drawbacks: manual cleaning requires stopping the vehicle, which is time-consuming, labor-intensive, and affects work efficiency; while electric cleaning devices can clean automatically, they consume onboard energy, increasing energy loss, and most can only perform simple scraping cleaning, which is ineffective at cleaning stubborn pollutants such as dried stains and bird droppings. Long-term use can lead to a decrease in the power generation efficiency of the photovoltaic panels, making it difficult to guarantee a stable supply of additional energy. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-functional mobile commercial vehicle that solves the problems of low booth construction efficiency, poor structural flexibility, and difficulty in balancing functionality and practicality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional mobile commercial vehicle, comprising:

[0007] The vehicle body, as the basic component of the overall device, is used to support the photovoltaic panels and assemble various processing mechanisms and their subordinate structural components;

[0008] The carriage, located on the top of the vehicle body, consists of fixed panels and movable panels. The three fixed panels are fixedly connected to the vehicle body, and the two movable panels are rotatably connected to the vehicle body via a pivot.

[0009] A quick-fixing structure is provided on the outer wall of one side of the movable panel, which is used to quickly connect the movable panel and the ground to form an extended exhibition stand;

[0010] A photovoltaic panel assembly, located on the top wall of one side of the fixed panel, provides additional energy to the vehicle body;

[0011] The follow-up cleaning structure is located on the outside of the photovoltaic panel assembly and cleans the photovoltaic panel assembly as the vehicle moves.

[0012] The follow-up cleaning structure, which is connected to the follow-up cleaning structure, sprays additional cleaning agent on the surface of the photovoltaic panel assembly.

[0013] Preferably, the quick-fixing structure includes a fixed shaft, which is installed on the outer wall of a movable side panel. An external screw is installed inside the fixed shaft, and an internal screw is threaded into the external screw. One end of the internal screw is fixedly connected to a grounding rod. The grounding rod has a storage cavity inside, which communicates with a slide rail on the outer wall of the grounding rod. An L-shaped rod is slidably connected inside the slide rail. One end of the L-shaped rod is fixedly connected to an adjusting ring, and the other end is fixedly connected to a top cone. When the top cone moves downward, it compresses an extension rod connected to the storage cavity by a tension spring.

[0014] Preferably, the follow-up cleaning structure includes a fixed rod, which is disposed on the top wall of a fixed side panel. A wind baffle plate is slidably connected to the outside of the fixed rod and a spring is provided thereon. The two ends of the spring are respectively connected to the fixed side panel of the wind baffle plate. A cleaning brush is fixedly connected to one side of the outer wall of the wind baffle plate.

[0015] Preferably, the follow-up cleaning structure includes a vehicle-mounted water tank, which is installed on the top of the fixed panel on one side. One side of the outer wall of the vehicle-mounted water tank is connected to a spray box via a delivery pipe. One side of the outer wall of the spray box is connected to a flow channel. A pressure plate is slidably connected inside the flow channel. One side of the outer wall of the pressure plate is connected to a wind baffle via a long rod. The outlet of the flow channel is provided with a diaphragm. The other side of the outer wall of the spray box is connected to a spray channel.

[0016] Preferably, the spray channel has an S-shaped cross-section, and the diaphragm is a composite material formed from semi-molten PVC and fiber mesh under high temperature and high pressure.

[0017] Preferably, the outer wall of one side of the movable panel is connected to an outer shell via a short shaft, and a chamfer is applied to one corner of the outer wall of the outer shell.

[0018] Preferably, the tension spring has a retraction rod inside, with its two ends connected to the storage cavity and the extension rod, respectively.

[0019] Preferably, one end of the L-shaped rod has a ramp, and the other end is a sharp spike.

[0020] Working Principle: This multi-functional mobile commercial vehicle uses the vehicle body as its basic load-bearing frame, with the cargo box located on top of the vehicle body. It consists of fixed and movable panels, with three fixed panels fixedly connected to the vehicle body and two movable panels rotatably connected to the vehicle body via pivots. Its working principle revolves around two core functions: booth construction and photovoltaic panel cleaning. When an extended booth needs to be constructed, the operator first rotates one movable panel around the pivot to unfold it, and then uses a quick-fixing structure to achieve stable fixation. A rotating adjustment ring moves an L-shaped rod down along the track of the ground-embedded rod. The sharp end of the L-shaped rod penetrates the ground to complete initial anchoring, while its pointed end enters the storage cavity of the ground-embedded rod, squeezing the extension rod and overcoming the tension spring force to push the extension rod outwards and wed it into the soil, achieving both vertical and horizontal anchoring. Furthermore, the outer wall of the movable panel is... The short-shaft connected outer shell provides auxiliary protection. When the vehicle is in motion, the follow-up cleaning structure and the follow-up cleaning structure work together to clean the photovoltaic panels. The airflow impacts the wind baffle, causing it to overcome the spring force and slide backward along the fixed rod, driving the cleaning brush to scrape the surface of the photovoltaic panels in one direction to remove debris. At the same time, the wind baffle, through the long rod, drives the pressure plate to move backward within the flow channel of the follow-up cleaning structure, squeezing the cleaning liquid in the flow channel. The liquid is squeezed into the S-shaped spray channel and atomized before being sprayed onto the surface of the photovoltaic panels, achieving deep cleaning through the synergy of scraping and spraying. When the vehicle speed decreases or stops, the spring drives the wind baffle to reset, the cleaning brush returns to its initial position, and the pressure plate returns to its original position to store energy for the next cleaning. The entire system achieves follow-up cleaning without the need for additional energy, and all structures can be compactly stored when retracted, ensuring the functionality and practicality of the commercial vehicle.

[0021] This invention provides a multi-functional mobile business vehicle. It has the following beneficial effects:

[0022] 1. This invention utilizes a rapid fixing structure design with a rotating adjustment ring and dual anchoring. Operators only need a single rotation to simultaneously achieve initial anchoring of the L-shaped rod vertically into the ground and secondary reinforcement of the extension rod horizontally wedged into the soil. No complex disassembly or additional auxiliary tools are required, greatly simplifying the booth construction process and improving work efficiency. At the same time, the dual anchoring structure significantly enhances the connection strength between the movable panel and the ground, effectively resisting overturning by external forces. Even in soft soil or light wind conditions, it can still ensure the stability of the booth, making it suitable for various scenarios such as outdoor exhibitions and temporary service stations.

[0023] 2. The present invention features a follow-up cleaning structure and a follow-up cleaning structure that work together. Utilizing the natural wind resistance of the vehicle during travel, the wind deflector is driven to move, allowing the cleaning brush to perform unidirectional scraping of the photovoltaic panels without consuming onboard energy. Simultaneously, the cleaning liquid is atomized and sprayed through a pressure plate, achieving a deep cleaning effect through simultaneous scraping and spraying. This not only efficiently removes accumulated dust, dried stains, and other debris that affect the photovoltaic panel's power generation efficiency but also avoids the energy consumption of traditional electric cleaning devices. Furthermore, the cleaning action automatically starts and stops according to the vehicle speed, requiring no manual intervention, reducing maintenance costs, and ensuring that the photovoltaic panels continuously and stably provide additional energy to the vehicle.

[0024] 3. The movable compartment of this invention can be flexibly unfolded and stored through the pivot. When the quick-fixing structure is retracted, the extension rod can retract back into the storage cavity under the action of the tension spring, and the L-shaped rod can be pulled out of the ground. All components can be compactly stored on the outside of the movable compartment without occupying extra space. The chamfering treatment of the corners of the outer shell can avoid personnel bumping into each other and improve the safety of use. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see the appendix Figure 1 -Appendix Figure 7 This invention provides a multi-functional mobile business vehicle, comprising:

[0035] The vehicle body 1 serves as the basic component of the overall device, used to support the photovoltaic panels and assemble various processing mechanisms and their subordinate structural components;

[0036] The carriage 2 is located on the top of the car body 1 and consists of fixed panels 3 and movable panels 4. The three fixed panels 3 are fixedly connected to the car body 1, and the two movable panels 4 are rotatably connected to the car body 1 through a rotating shaft 5.

[0037] The quick-fixing structure 6 is located on the outer wall of the movable panel 4 on one side, and is used to quickly connect the movable panel 4 and the ground to form an extended exhibition stand;

[0038] The photovoltaic panel 7 is installed on the top wall of the fixed panel 3 on one side, providing additional energy to the vehicle body 1;

[0039] The follow-up cleaning structure 8 is located on the outside of the photovoltaic panel group 7 and cleans the photovoltaic panel group 7 while the vehicle body 1 is moving.

[0040] The follow-up cleaning structure 9, which is connected to the follow-up cleaning structure 8, additionally sprays cleaning agent onto the surface of the photovoltaic panel assembly 7.

[0041] The quick-fixing structure 6 includes a fixed shaft 10, which is installed on the outer wall of a movable side panel 4. An external screw 11 is installed inside the fixed shaft 10, and an internal screw 12 is threadedly connected to the external screw 11. One end of the internal screw 12 is fixedly connected to a ground-embedded rod 13. A storage cavity 14 is opened inside the ground-embedded rod 13, which is connected to a slide rail 15 on the outer wall of the ground-embedded rod 13. An L-shaped rod 16 is slidably connected inside the slide rail 15. An adjusting ring 17 is fixedly connected to one end of the L-shaped rod 16, and a top cone 18 is fixedly connected to the other end. When the top cone 18 moves down, it squeezes the extension rod 20 connected to the storage cavity 14 by a tension spring 19.

[0042] The outer wall of one movable panel 4 is connected to an outer shell 34 via a short shaft 33, and a chamfer is applied to one corner of the outer wall of the outer shell 34.

[0043] The tension spring 19 has a retraction rod 35 inside, with its two ends connected to the storage cavity 14 and the extension rod 20, respectively.

[0044] One end of the L-shaped rod 16 has a slope 36, and the other end is a sharp spike.

[0045] Specifically, when it is necessary to fix the unfolded movable panel 4 to the ground to form a stable display platform, the operator first rotates the adjusting ring 17. The adjusting ring 17 drives the L-shaped rod 16 fixed to it to slide downwards along the slide rail 15. The sharp spike-like part at the lower end of the L-shaped rod 16 pierces the ground, achieving initial positioning and anchoring. As the L-shaped rod 16 continues to move downwards, the top cone 18 fixed to it enters the storage cavity 14 of the ground-embedded rod 13, and applies downward compressive force to the end of the extension rod 20 stored in the cavity. Under the action of the inclined surface of the top cone 18 and the end of the extension rod 20, the compressive force is decomposed into a horizontal component, overcoming the contraction force of the tension spring 19, and pushing multiple extension rods 20 to extend horizontally from the storage cavity 14 in all directions, wedging into the surrounding soil. The function of the retractable rod 35 is to limit the stroke of the extension rod 20 and assist its precise repositioning. This process, through the action of a single rotating adjusting ring 17, simultaneously achieves dual anchoring in both the vertical and horizontal directions, greatly enhancing the overall structure's grip and anti-overturning ability in the soil, ensuring the stability of the display stand. During recovery, the adjusting ring 17 is rotated in the opposite direction, the top cone 18 moves upward, and the tension of the tension spring 19 pulls the extension rod 20 back into the storage cavity 14, while the L-shaped rod 16 is pulled out of the ground. The entire structure can then be compactly stored on the outside of the movable panel 4.

[0046] The follow-up cleaning structure 8 includes a fixed rod 21, which is located on the top wall of a fixed side panel 3. A wind baffle 22 is slidably connected to the outside of the fixed rod 21 and a spring 23 is provided. The two ends of the spring 23 are respectively connected to the fixed side panel 3 of the wind baffle 22. A cleaning brush 24 is fixedly connected to one side of the outer wall of the wind baffle 22.

[0047] Specifically, when the vehicle body 1 is moving, the airflow in front impacts the wind deflector 22, causing it to overcome the elastic force of the spring 23 and slide backward along the fixed rod 21. The cleaning brush 24, fixedly connected to the wind deflector 22, then performs unidirectional scraping on the surface of the photovoltaic panel 7, removing accumulated dust, leaves, and other debris. When the vehicle speed decreases or stops, the wind resistance decreases or disappears, and the restoring force of the spring 23 drives the wind deflector 22, along with the cleaning brush 24, to slide forward, returning to its initial position, ready for the next work cycle. This process achieves a self-cleaning function that utilizes only the power of wind resistance without consuming additional onboard energy during vehicle operation.

[0048] The following cleaning structure 9 includes a vehicle-mounted water tank 25, which is installed on the top of a fixed panel 3 on one side. One side of the outer wall of the vehicle-mounted water tank 25 is connected to a spray box 27 via a delivery pipe 26. One side of the outer wall of the spray box 27 is connected to a flow channel 28. A pressure plate 29 is slidably connected inside the flow channel 28. One side of the outer wall of the pressure plate 29 is connected to a wind baffle 22 via a long rod 30. A diaphragm 31 is provided at the outlet of the flow channel 28. The other side of the outer wall of the spray box 27 is connected to a spray channel 32.

[0049] The spray channel 32 has an S-shaped cross-section, and the diaphragm 31 is a composite material formed by semi-molten PVC and fiber mesh under high temperature and high pressure.

[0050] Specifically, when the wind baffle 22 slides backward due to wind resistance, the pressure plate 29 moves backward within the flow channel 28 simultaneously via the long rod 30. The front end of the flow channel 28 is connected to the vehicle-mounted water tank 25 via the delivery pipe 26 and is filled with cleaning liquid. The backward movement of the pressure plate 29 compresses the liquid encased in the diaphragm 31 in front, causing a sudden increase in pressure. When the pressure reaches a set threshold, this portion of liquid enters the spray channel 32 under compression. As the pressurized liquid then surges into the S-shaped spray channel 32, the S-shaped flow channel 28 effectively turbulentizes the water flow, atomizing it and spraying it evenly onto the surface of the photovoltaic panel 7. The spraying operation is coordinated with the scraping action of the cleaning brush 24, achieving a deep cleaning effect through the coordinated operation of spraying and cleaning, especially suitable for removing dried stains or bird droppings and other adhering substances. When the wind baffle 22 returns to its original position under the action of the spring 23, the pressure plate 29 also returns to its original position, storing power for the next compression.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
