Description

Technical Field

[0001] This utility model relates to the field of food cart technology, specifically to a mobile food cart. Background Technology

[0002] In the food and beverage retail sector, mobile food trucks are widely used in street food and beverage sales due to their flexibility and low-cost operation. Most existing mobile food trucks are modified from basic vehicle bodies such as tricycles and handcarts, but their structural designs generally suffer from the following shortcomings:

[0003] Space utilization and functional integration defects: Traditional food carts lack reasonable zoning of the operation area and equipment storage area. They are mostly single-layer open structures with small operation platforms and exposed equipment (such as ice cream machines and milk tea insulated buckets). The bottom space is not effectively utilized, and accessories such as power supplies are inconvenient to store. They are easily affected by the external environment (such as rain and dust intrusion). Furthermore, the mixed "operation-storage" functions lead to chaotic management.

[0004] Insufficient compatibility and convenience of modification: Existing modification solutions often require significant alterations to the main structure of the vehicle, such as welding and cutting. For example, building a support frame directly on the top of the vehicle not only damages the stability of the original structure but also has poor compatibility with different vehicle types such as tricycles and handcarts, requiring customized design. This results in high modification costs and long cycles, making it particularly unsuitable for individual businesses to modify on their own.

[0005] To address the aforementioned issues, there is an urgent need to develop a mobile food truck that can overcome the shortcomings of existing technologies, such as complex structure, poor compatibility with existing vehicle bodies, and high modification costs. Utility Model Content

[0021] The present invention achieves the following technical advantages over the prior art:

[0022] This utility model provides a mobile food cart whose supporting platform directly reuses the existing vehicle body's top support frame (such as the top of a tricycle frame or the roof of a handcart), without requiring significant modifications to the main structure of the vehicle body. The bottom support frame of the supporting frame layer is an independent horizontal frame, directly laid on the supporting platform; the front and rear support frames and the operating panel constitute independent assembly modules, connected to the front and rear ends of the bottom support frame, forming an upper structure of "support frame + operating panel," quickly completing the assembly of functional components such as "operating panel - door panel - enclosure panel," combining space utilization, convenient modification, and structural stability. This allows existing vehicles to be easily and efficiently upgraded into mobile food carts with operation and storage functions. The structure is simple, has good compatibility with vehicle bodies, and has low modification costs. It is especially suitable for mobile vending scenarios such as ice cream and milk tea that require immediate operation and power support.

[0023] The control panel and the support platform are parallel to each other, forming a two-layer space structure of "upper operation area + lower storage area".

The three-state switching (folding, unfolding, and closing) mechanism of the first and second operating area baffles, through the cooperation of the support shaft and sliding groove, allows the baffles to be stacked and stored above the operating platform in the folded state without occupying extra space. In the unfolded state, the baffles form a stable sunshade and rainproof structure by engaging with the support shaft through the arc-shaped groove, providing protection for operators and customers respectively. Secondly, the baffles form a rotating joint with the support shaft through the groove, allowing them to be folded to a vertical position and abut against the side of the operating panel. Together with the first and last baffles, this effectively closes the operating area. Furthermore, the overlapping flanges, sealing strips, and locking structures on the edges of the baffles enhance anti-theft and sealing performance. In addition, the handle at the beginning of the baffle facilitates operation, and the limiting design of the support shaft and groove ensures the stability of the sliding process. The overall structure combines practicality, safety, and space utilization. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] This embodiment provides a mobile food cart; please refer to [reference needed]. Figure 1-13As shown, the system includes a vehicle body 1, a support frame, and an operating panel 2. A load-bearing platform 3 is mounted on the top of the vehicle body 1, preferably forming a support frame on the top of the vehicle body 1. The vehicle body 1 includes wheels 4 capable of driving the load-bearing platform 3. The support frame includes a bottom support frame 5, a front support frame 6, and a rear support frame 7. The bottom support frame 5 includes a horizontal frame laid on the load-bearing platform 3 of the vehicle body 1. The front support frame 6 and the rear support frame 7 are respectively connected to the front and rear ends of the bottom support frame 5, and both can be fixedly connected to the bottom support frame 5 by welding or bolting. The front support frame 6 and the rear support frame 7 are arranged opposite to each other and are parallel to each other. The front and rear ends of the operating panel 2 are respectively mounted on the front support frame 6 and the rear support frame 7, and the operating panel 2 is arranged opposite to the load-bearing platform 3, located above the load-bearing platform 3; preferably, the operating panel 2 is parallel to the load-bearing platform 3. The top surface of the control panel 2 forms the operating platform 8, and the area opposite the control panel 2 and the support platform 3 forms the equipment accommodating area. The horizontal frame of the bottom support frame 5 includes a first side and a second side; a door 9 is hinged to the first side of the bottom support frame 5. Preferably, the hinge axis of the door 9 is parallel to the line connecting the front and rear ends of the vehicle body 1. The rotation trajectory of the door 9 includes a closed position. The door 9 in the closed position constitutes the first side wall of the equipment accommodating area. At this time, the door 9 is vertically set, and the top of the door 9 can abut against the control panel 2, while the bottom of the door 9 abuts against the horizontal frame. A sealing plate 10 is connected to the second side of the horizontal frame. The sealing plate 10 can be fixedly connected to the horizontal frame and constitutes the second side wall of the equipment accommodating area. The door 9 in the closed position and the sealing plate 10 are opposite and parallel to each other, and both can simultaneously seal the two side walls of the equipment accommodating area. The front support frame 6 and the rear support frame 7 constitute the front and rear boundaries of the equipment accommodating area. An ice cream machine 26, a milk tea insulated container 27, etc., can be placed on the operating platform 8, allowing personnel to work on the platform. A power supply can be placed in the equipment housing area to power the ice cream machine 26 and the milk tea insulated container 27. In this embodiment, the "head" refers to the front end of the vehicle body 1 along a preset travel direction, and the "tail" refers to the rear end along the preset travel direction. When the vehicle body 1 is a tricycle 31, the "head" refers to the front end where the handlebars 30 are installed, and the "tail" refers to the rear end where the rear wheels are located; when the vehicle body 1 is a handcart 32, the "head" refers to the end of the vehicle body 1 that is in front in the travel direction when pushed by the operator, and the "tail" refers to the opposite end. A skin can be installed on the horizontal frame, and power supplies and other equipment can be directly mounted on the skin.

[0045] Working principle:

[0046] The wheels 4 at the bottom of the vehicle body 1 (the tricycle 31 has a single front wheel and two rear wheels, and the handcart 32 has four wheels) support the weight of the entire food cart and move by pushing (handcart 32) or riding (tricycle 31).

[0047] The support platform 3 serves as the top support frame of the vehicle body 1, supporting the bottom support frame 5 and transferring the weight of the control panel 2, equipment, etc., to the vehicle body 1 through the support frame, ensuring structural stability during movement. The control panel 2 is mounted on the front support frame 6 and the rear support frame 7, forming a horizontal control platform 8. Equipment such as ice cream machine 26 and milk tea insulated bucket 27 can be placed on the control platform 8, and personnel can perform production and sales operations on the control platform 8. The equipment storage area is enclosed by the control panel 2, the support platform 3, the front support frame 6, the rear support frame 7, and the bottom support frame 5, and stores the power supply (such as a battery) inside, which is connected to the equipment on the control platform 8 through cables to achieve continuous power supply.

[0048] The door leaf 9 is hinged to the first side of the bottom support frame 5. The hinge axis of the door leaf 9 is parallel to the direction of the line connecting the front and rear of the vehicle body 1 and can rotate around the axis. When closed, the door leaf 9 extends vertically upward, with the top abutting against the operating panel 2 and the bottom abutting against the horizontal frame, forming the left side wall of the equipment accommodating area and sealing the left side space.

[0049] When door 9 is opened, it rotates outward, exposing the left side of the equipment storage area, making it convenient for personnel to access power supplies or equipment. The sealing plate 10 is fixedly connected to the second side of the bottom support frame 5, always vertically sealing the right side of the equipment storage area, forming a closed structure on both sides with the closed door 9 to prevent equipment from falling or foreign objects from entering.

[0050] The load-bearing platform layer of this utility model utilizes the existing vehicle body 1, using the supporting frame at the top of the vehicle body 1 (such as the top of the frame of the tricycle 31 or the top plate of the handcart 32) as the basic load-bearing platform 3. No changes are needed to the main structure of the vehicle body 1; only the levelness and load-bearing capacity of the platform need to be confirmed. The bottom support frame 5 of the supporting frame layer is an independent horizontal rectangular frame, directly fixed to the load-bearing platform 3 of the existing vehicle body 1 by bolts or welding. Its dimensions can be customized according to the top space of the existing vehicle body 1 (e.g., the length adapts to the tricycle 31's cargo box, and the width covers the top plate of the handcart 32).

[0051] The front support frame 6, the rear support frame 7, and the operating plate 2 form an independent assembly module, which is connected to the front and rear ends of the bottom support frame 5 to form an upper structure of "support frame + operating plate", which is independent of the existing vehicle body 1's running system (running wheels 4).

[0052] Example of a modified tricycle (using a common freight tricycle as an example)

[0053] S1: Platform compatibility:

[0054] The top of the existing tricycle 31 is usually an open frame, which directly uses the frame beam as the load-bearing platform 3. If the height is insufficient, shims can be added to adjust the height of the horizontal frame (bottom support frame 5) to ensure that the height of the operating panel 2 from the ground meets the ergonomic requirements.

[0055] S2: Support frame installation:

[0056] The horizontal frame of the bottom support frame 5 is fixed to the crossbeam of the tricycle frame 31 with bolts. The front support frame 6 is close to the front of the vehicle, and the rear support frame 7 is close to the rear of the vehicle. There is no need to modify the original parts such as the handlebars 30 and the seat 11.

[0057] S3: Operation module assembly:

[0058] The control panel 2 is mounted on the front support frame 6 and the rear support frame 7. The door 9 is hinged to the side of the bottom support frame 5 near the operator. The enclosure 10 is fixed to the other side. The entire process does not require any changes to the power system and wheel layout of the tricycle 31.

[0059] Example of modifying a handcart 32 (taking a four-wheeled flatbed handcart 32 as an example):

[0060] The top flat plate of the handcart 32 serves directly as the load-bearing platform 3, and the bottom support frame 5 is fixed to the four corners of the flat plate with bolts. After the front support frame 6 and the rear support frame 7 are installed vertically, the height of the operating plate 2 can be adjusted by the length of the support frame tubing (such as using a telescopic sleeve) to accommodate operators of different heights.

[0061] The handcart 32 is equipped with handles 33 at both ends and the rear end. The bottom of the handcart 32 is equipped with wheels 4, preferably swivel wheels, to ensure that the handcart 32 moves stably.

[0062] This utility model offers significant convenience and compatibility for modifying existing vehicle bodies 1, achieving modular structural design and standardized connection methods. In the technical solution, the supporting platform 3 directly reuses the existing support frame on the top of the vehicle body 1 (such as the top of the tricycle frame 31 or the top plate of the handcart 32), without requiring significant alterations to the main structure of the vehicle body 1. The bottom support frame 5 of the support frame layer is an independent horizontal frame, directly laid on the supporting platform 3. Its dimensions can be flexibly customized to adapt to different top spaces of the vehicle body 1 (such as the length of the tricycle 31's cargo box or the width of the top plate of the handcart 32). The operating module, consisting of the front support frame 6, the rear support frame 7, and the operating panel 2, is independently connected to the front and rear ends of the bottom support frame 5, independent of the vehicle body 1's walking system, ensuring that the modification does not affect the original power or steering function; it enables rapid assembly without damaging the original vehicle structure. The modular design allows existing vehicle body 1 to be upgraded into a mobile food truck with operation and storage functions without the need for professional tools or complicated procedures. This significantly reduces the technical threshold and cost of modification, making it especially suitable for individual merchants to modify their own vehicle body 1 independently, taking into account both practicality and economy.

[0063] The operation panel 2 and the support platform 3 of this utility model are parallel to each other, forming a double-layer space structure of "upper operation area + lower storage area". This not only meets the equipment operation requirements, but also utilizes the bottom space to store accessories such as power supplies, thus improving space utilization. It realizes modular isolation of "operation-storage" functions, which facilitates equipment classification and management.

[0064] The hinged design of door 9 balances "sealing and anti-theft" with "easy access": when closed, it forms a fully sealed sidewall together with the sealing plate 10 to prevent rainwater and dust from entering the equipment storage area; when open, it is open on one side for easy access to items. The horizontal frame of the bottom support frame 5, together with the front support frame 6 and the rear support frame 7, forms a "rectangular support skeleton". The load of the operating panel 2 is evenly transferred to the vehicle body 1 through the support frame, which has good load-bearing capacity, good stability, and small offset under vibration environment, making it suitable for mobile scenarios.

[0065] This food cart overcomes the pain points of traditional mobile food carts, such as "small operating space and inconvenient equipment storage," through a structural combination of "layered space + openable side walls + stable support." It is especially suitable for scenarios such as ice cream and milk tea that require immediate operation and power support, and combines mobility, complete functionality, and safety.

[0066] Taking the freight tricycle 31 as an example, the modification can be quickly completed by simply using the existing frame beam as the load-bearing platform 3, fixing the bottom support frame 5 with bolts and installing the operating plate 2, without modifying the handlebars 30, seat 11, or other components. When modifying the handcart 32, the top flat plate directly serves as the load-bearing platform 3, and the bottom support frame 5 is fixed with four corner bolts. The height of the operating plate 2 can be adjusted with the telescopic sleeve to accommodate operators of different heights. The support frame is installed away from the handlebar rotation axis, fully preserving the swivel wheel steering and push-pull functions of the handcart 32. This utility model can completely retain the existing vehicle body 1's walking wheels 4, power system (such as the tricycle 31 motor), and steering mechanism, only "overlaying" the support-operation module on the top. After modification, the wheelbase and center of gravity of the vehicle body 1 change little, without affecting driving stability. The edges of the operating plate 2, door 9, and enclosure 10 are all pre-set with standardized mounting holes, which correspond one-to-one with the connection holes of the support frame, achieving "plug and play" and allowing a single person to complete the modification.

[0067] In this embodiment, the bottom support frame 5 and the load-bearing platform 3 of the vehicle body 1 can be connected by U-bolt clamps or L-shaped angle bracket bolts, which will not damage the original vehicle structure after disassembly; the front support frame 6 and the rear support frame 7 can be connected to the bottom support frame 5 by bolts or welding, which can be quickly assembled on site; the operation plate 2 can be fixed to the support frame front support frame 6 and rear support frame 7 by bolts + rubber pads, which can ensure flatness and prevent vibration from loosening. The operation plate 2 can also be directly connected to the support frame front support frame 6 and rear support frame 7 by welding.

[0068] In one embodiment, the horizontal frame includes at least two bottom crossbars 12 arranged along the width direction of the vehicle body 1 (perpendicular to the line connecting the front and rear ends), and a first bottom side bar 13 and a second bottom side bar 14 arranged along the length direction of the vehicle body 1 (the direction connecting the front and rear ends). The two ends of the bottom crossbars 12 are fixedly connected to the first bottom side bar 13 and the second bottom side bar 14 respectively, forming a rectangular frame structure. The first bottom side bar 13 is used to hinge the door leaf 9, and the second bottom side bar 14 is used to fix the sealing plate 10. The bottom crossbars 12 can be bolted or welded to the first bottom side bar 13 and the second bottom side bar 14. The sealing plate 10 is vertically fixed to the outside of the second bottom side bar 14, opposite to the door leaf 9 on the first bottom side bar 13. Preferably, the door leaf 9 is hinged to the outside of the first bottom side bar 13 via a hinge axis parallel to the line connecting the front and rear ends of the vehicle body 1, allowing the door leaf 9 to rotate outwards around the axis.

[0069] In this embodiment, there are at least two bottom crossbars 12, evenly spaced along the length of the vehicle body 1, with a spacing of 30-50cm between adjacent bottom crossbars 12 to ensure the load-bearing strength of the horizontal frame. The bottom crossbars 12 can be connected to the vehicle body 1 by bolts or welding. The closing plate 10 is a rectangular plate structure, with its top abutting against the side of the operating plate 2, and its lower part extending downward beyond the second bottom side bar 14. The operating plate 2 can form a complete right side wall of the equipment accommodating area.

[0070] In one embodiment, the control panel 2 is provided with at least one through hole, which is a through hole penetrating the control panel 2. The bottom opening of the through hole communicates with the equipment housing area, and the top opening of the through hole extends to the surface of the control platform 8. The through hole is preferably located in the edge area of ​​the control panel 2 (such as the side near the head support frame 6) to facilitate the connection of the power cord 29. An insulating rubber sealing ring is embedded in the edge of the through hole to prevent cable abrasion or liquid seepage. Preferably, there are 1-3 through holes with a diameter of 10-20mm, which can simultaneously pass through multiple power cords 29 or control lines. When not in use, the top opening of the through hole can be sealed with a snap-on waterproof cover to improve the waterproof and dustproof performance of the equipment housing area.

[0071] In one embodiment, both the top of the first end support frame 6 and the tail end support frame 7 have a vertical support section 21 that protrudes upward from the operating plate 2. The vertical support section 21 extends vertically upward, and the upper region of the vertical support section 21 is provided with a first operating area baffle 15 and a second operating area baffle 16. Both the first operating area baffle 15 and the second operating area baffle 16 have three states: folded, unfolded, and closed.

[0072] Support mechanism: Two vertical support sections 21 on the first side (left side) are each fixed with a first support shaft 17, that is, the vertical support sections 21 of the first end support frame 6 and the rear end support frame 7 on the first side are each provided with a first support shaft 17; the first side also refers to the side with the door leaf 9, the two first support shafts 17 are arranged opposite each other and are laterally aligned, the axis of any one of the first support shafts 17 is parallel to the direction of the line connecting the front and rear of the vehicle body 1, and the first operating area baffle 15 is slidably engaged with the first support shaft 17; preferably, the bottom surface of the first operating area baffle 15 is provided with a sliding groove, which is slidably engaged with the first support shaft 17; two vertical support sections 21 on the second side (right side) are each fixed with a second support shaft 19, the second side also refers to the side with the closing plate 10, the two second support shafts 19 are arranged opposite each other and are laterally aligned, the axis of any one of the second support shafts 19 is parallel to the direction of the line connecting the front and rear of the vehicle body 1, and the second operating area baffle 16 is slidably engaged with the second support shaft 19.

[0073] In this embodiment, the ends of the first operating area baffle 15 and the second operating area baffle 16 are respectively provided with a first slot 18 and a second slot 20; the second slot 20 is higher than the top surface of the first operating area baffle 15 to avoid interference during sliding. The first slot 18 includes a first engagement position in the sliding trajectory of the first operating area baffle 15. The first slot 18 located at the first engagement position engages with the first support shaft 17. At this time, the first operating area baffle 15 is in the unfolded position. The second slot 20 includes a second engagement position in the sliding trajectory of the second operating area baffle 16. The second slot 20 located at the second engagement position engages with the second support shaft 19. At this time, the second operating area baffle 16 is in the unfolded position.

[0074] In this embodiment, both the first slot 18 and the second slot 20 are arc-shaped slots. The first slot 18, located at the first engagement position, rotates with the first support shaft 17 to form a rotating pair; the second slot 20, located at the second engagement position, rotates with the second support shaft 19 to form a rotating pair. The first operating area baffle 15 includes a first abutting end away from the first slot 18. At this time, the trajectory of the first operating area baffle 15 rotating around the first support shaft 17 includes a first vertical position, and the first operating area baffle 15 is in a vertical state. The first abutting end located at the first vertical position abuts against the first side (left side) of the operating plate 2. The second operating area baffle 16 includes a second abutting end away from the second slot 20. The second slot 20, located at the second engagement position, forms a rotating pair with the second support shaft 19. The trajectory of the second operating area baffle 16 rotating around the second support shaft 19 includes a second vertical position, and the second operating area baffle 16 is in a vertical state. The second abutting end located at the second vertical position abuts against the second side (right side) of the operating plate 2. Both the starting part of the first operating area baffle 15 and the starting part of the second operating area baffle 16 have baffle handles 37, which allow personnel to easily pull the first operating area baffle 15 and the second operating area baffle 16.

[0075] In the folded state: the starting part of the first operating area baffle 15 abuts against the first support shaft 17, and the end of the first operating area baffle 15 is supported on the vertical support section 21 on the right side; preferably, a support flange is provided at the end of the first support shaft 17, and a support groove for engaging with the support flange is provided on the first support shaft 17 on the right side. When the first operating area baffle 15 is in the folded state, the support flange of the first operating area baffle 15 can engage with the support groove, and the first operating area baffle 15 horizontally covers the operating platform 8.

[0076] The second operating area baffle 16, in its folded state, is stacked above the first operating area baffle 15, in its folded state. The starting part of the second operating area baffle 16 abuts against the second support shaft 19, and the ending part of the second operating area baffle 16 is supported on the vertical support section 21 on the left. Similarly, the second operating area baffle 16 in its folded state can also be supported by the cooperation structure of the support flange and the support groove. In this way, in the folded state, the second operating area baffle 16 is stacked above the first operating area baffle 15, and both horizontally cover the operating platform 8: the first operating area baffle 15 is located on the lower layer and is supported by the first support shaft 17 on the left and the vertical support section 21 on the right; the second operating area baffle 16 is located on the upper layer and is supported by the second support shaft 19 on the right and the vertical support section 21 on the left, forming a stacked storage structure.

[0077] In the unfolded state: The first operating area baffle 15 slides to the left, and the arc-shaped first slot 18 at its tail end engages with the first support shaft 17, forming a horizontally extending sunshade and rainproof structure. The maximum extension is limited by the slot. The first operating area baffle 15 provides sunshade and rainproof for operators, and simultaneously, the second operating area baffle 16 can slide to the right. The arc-shaped second slot 20 at the tail end of the second operating area baffle 16 engages with the second support shaft 19, providing sunshade and rainproof for customers. The first operating area baffle 15 in the unfolded position provides sunshade and rainproof for the area on the side of the door leaf 9, and the second operating area baffle 16 in the unfolded position provides sunshade and rainproof for the area on the side of the enclosure panel 10. The area above the operating platform 8 is the operating area, through which personnel can perform operations.

[0078] In the closed state: the first slot 18 of the first operating area baffle 15 folds down to the vertical position with the first support shaft 17 as the fulcrum of rotation, and the lower end of the starting part of the first operating area baffle 15 abuts against the left side of the operating plate 2, thus closing the left side of the operating area; the second slot 20 of the second operating area baffle 16 folds down to the vertical position with the second support shaft 19 as the fulcrum of rotation, and the lower end of the starting part of the second operating area baffle 16 abuts against the right side of the operating plate 2; thus symmetrically closing the right side of the operating area to prevent external intrusion.

[0079] In this embodiment, the curvature of the first slot 18 and the second slot 20 matches the outer diameter of the first support shaft 17 and the second support shaft 19, respectively, to ensure smooth sliding and rotation limit; the baffle is made of steel structure material, and in the folded state, the whole is located above the operating platform 8, without occupying extra space.

[0080] In this embodiment, a telescopic rod is connected to the middle of the outer side of each vertical support section 21. Preferably, the telescopic rod is horizontally hinged to the vertical support section 21 via a pin, and the pin can be fixed to the vertical support section 21 with bolts to prevent the telescopic rod from rotating in the vertical support section 21. The telescopic rod is a sleeve-type telescopic structure, with its lower end hinged to the vertical support section 21 and its upper end provided with a hook for engaging with the operating area baffle. The hook is preferably an L-shaped hook. When the first operating area baffle 15 or the second operating area baffle 16 slides to the unfolded position, the operator pulls the telescopic rod outward, causing its inner rod to extend from the outer rod; so that the inner rod supports the bottom surface of the first operating area baffle 15 or the second operating area baffle 16; preferably, the L-shaped hook at the upper end of the inner rod can hook into the groove on the bottom surface of the baffle. At this time, the telescopic rod is arranged at an angle of 55° with the vertical support section 21. The telescopic rod, together with the vertical support section 21, the first operating area baffle 15 or the second operating area baffle 16, forms a triangular support structure. The vertices of the triangle are the hinge point of the vertical support section 21, the baffle support point, and the telescopic rod extension end point, respectively.

[0081] In this embodiment, a spring pin is provided on the telescopic rod. When the inner rod extends to a predetermined length, the spring pin pops out and inserts into the positioning hole of the outer rod. The spring pin passes through the inner rod and the outer rod, locking the inner rod and the outer rod. With the interference fit between the L-shaped hook and the slot, double locking is achieved. This ensures that the baffle is stably supported in the unfolded position, providing reliable sunshade and rain protection for operators and customers.
