Description

Technical Field

[0001] This utility model relates to the field of food delivery vehicle technology, specifically to an adjustable vehicle body structure for a food delivery vehicle. Background Technology

[0002] A food delivery vehicle is a vehicle specifically designed for transporting food and beverages. It is typically used for takeout delivery, group catering, and mobile food truck operations. A food delivery vehicle mainly consists of a vehicle body and a cargo compartment.

[0003] In the existing technology, solar panels are installed on the roof of the delivery vehicle to charge the battery inside the vehicle. When the solar panels are exposed to the outside world and encounter hail, rain or strong winds, they may be cracked or scratched, affecting their service life. In the existing technology, the operator usually drives the delivery vehicle to a covered place or takes out a tarpaulin to cover the solar panels. However, there may not be a suitable rain shelter or garage nearby, especially when delivering outdoors or temporarily parking. In addition, each time the tarpaulin is covered or removed, it must be done manually, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable carriage structure for a food delivery vehicle, which solves the problem in the prior art that it is inconvenient to protect the solar panels on the roof of the carriage when encountering severe weather.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an adjustable carriage structure for a food delivery vehicle, comprising a carriage body, an installation opening on the upper surface of the carriage body, an adjustment structure inside the installation opening, a solar panel inside the adjustment structure, and an outer shell. The outer shell contains two sets of lifting components, and an opening on its upper surface. Each of the two sets of lifting components has a baffle plate at its upper end, and both baffle plates are slidably connected inside the opening. A drive assembly is located on the outer surface of the outer shell, which is situated inside the opening. Connecting lugs are also provided on the outer surface of the outer shell, and these connecting lugs are bolted to the inner top of the carriage body.

[0007] Furthermore, the lifting assembly includes a first connecting shaft, which is rotatably connected to the inner surface of the housing. A first connecting rod, a sector gear, and a spur gear are fixedly mounted on the outer surface of the first connecting shaft. The other end of the first connecting rod is hinged to the outer surface of the baffle plate. A rack is provided at one end of the spur gear. A support seat is mounted on the upper surface of the rack. A solar panel is mounted on the upper surface of the support seat. The rack meshes with the spur gear.

[0008] Furthermore, a second connecting shaft is rotatably connected to the inner surface of the outer shell, and a second connecting rod is fixedly installed on the outer surface of the second connecting shaft. The other end of the second connecting rod is hinged to the outer surface of the baffle plate.

[0009] Furthermore, the drive assembly includes a drive motor, which is mounted on the outer surface of the housing via a fixing member. A connecting frame is mounted on the outer surface of the housing, and a worm gear is rotatably connected inside the connecting frame. One end of the worm gear passes through the connecting frame and is fitted with a transmission wheel. A drive wheel is mounted on the output end of the drive motor, and the drive wheel is connected to the transmission wheel via a belt. In one of the lifting assemblies, a first connecting shaft passes through the housing and is fitted with a driven gear, which meshes with the worm gear.

[0010] Furthermore, the sector gears in the two adjacent lifting components mesh with each other.

[0011] Furthermore, a protective shell is installed on the outer surface of the outer casing, and the drive motor, drive wheel, transmission wheel, belt, worm gear and driven gear are all located inside the protective shell.

[0012] This utility model has the following beneficial effects:

[0013] (1) This utility model drives the spur gear to rotate through the first connecting shaft, so that the rack meshing with it moves in the vertical direction. The rack pushes the solar panel to rise or fall through the support seat to achieve height adjustment. When the first connecting shaft rotates, the first connecting rod fixed on it rotates with the shaft and pushes the shielding plate to slide along the outer shell opening through the hinge point. The second connecting rod on the second connecting shaft rotates synchronously to help the shielding plate to open or close smoothly, forming a cover or exposure of the solar panel. When the shielding plate is closed, it can protect the solar panel from the effects of severe weather and extend the life of the solar panel. The sector gears in the adjacent lifting components mesh with each other to ensure that the two sets of lifting actions are synchronized and avoid uneven force on one side.

[0014] (2) This utility model completely encloses the drive motor, drive wheel, transmission wheel, belt, worm gear and driven gear through the protective shell, effectively isolating external pollutants such as rainwater, dust, and sand, preventing key components from rusting or clogging, and extending the service life of the drive components.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-5As shown, this utility model is an adjustable carriage structure for a food delivery vehicle, including a carriage body 1. The upper surface of the carriage body 1 has an installation port, and an adjustment structure 2 is provided inside the installation port. A solar panel 3 is provided inside the adjustment structure 2. The adjustment structure 2 includes a housing 201, and two sets of lifting components 202 are provided inside the housing 201. An opening is provided on the upper surface of the housing 201. A baffle 203 is provided at the upper end of each of the two sets of lifting components 202. The two baffles 203 are slidably connected inside the opening. A drive component is provided on the outer surface of the housing 201. The housing 201 is located inside the opening. A connecting lug 205 is provided on the outer surface of the housing 201. The connecting lug 205 is installed on the inner top of the carriage body 1 by bolts.

[0026] When the solar panel 3 is not needed, the adjustment structure 2 can lower the solar panel 3 into the housing 201 and completely cover it with the shielding plate 203 to avoid damage caused by external factors such as dust, rain, and hail.

[0027] The lifting assembly 202 includes a first connecting shaft 2021, which is rotatably connected to the inner surface of the housing 201. A first connecting rod 2022, a sector gear 2023, and a spur gear 2024 are fixedly installed on the outer surface of the first connecting shaft 2021. The other end of the first connecting rod 2022 is hinged to the outer surface of the baffle plate 203. A rack 2025 is provided at one end of the spur gear 2024. A support seat 2026 is installed on the upper surface of the rack 2025. A solar panel 3 is installed on the upper surface of the support seat 2026. The rack 2025 is meshed with the spur gear 2024.

[0028] The inner surface of the outer casing 201 is also rotatably connected to a second connecting shaft 2027, and a second connecting rod 2028 is fixedly installed on the outer surface of the second connecting shaft 2027. The other end of the second connecting rod 2028 is hinged to the outer surface of the baffle plate 203.

[0029] The first connecting rod 2022 and the second connecting rod 2028 together constrain the sliding trajectory of the baffle plate 203 to prevent deviation or shaking.

[0030] The drive assembly includes a drive motor 2041, which is mounted on the outer surface of the housing 201 via a fixing member 4. A connecting frame 5 is mounted on the outer surface of the housing 201, and a worm gear 2042 is rotatably connected inside the connecting frame 5. One end of the worm gear 2042 passes through the connecting frame 5 and is fitted with a transmission wheel 2043. A drive wheel 2044 is mounted on the output end of the drive motor 2041, and the drive wheel 2044 is connected to the transmission wheel 2043 via a belt 2045. In one set of lifting components 202, a first connecting shaft 2021 is provided, one end of which passes through the housing 201 and is fitted with a driven gear 2046, which meshes with the worm gear 2042.

[0031] The sector gears 2023 provided in the two adjacent lifting components 202 mesh with each other;

[0032] The sector gears 2023 in adjacent lifting components 202 mesh with each other to ensure that the two sets of lifting actions are synchronized and to avoid uneven force on one side.

[0033] The outer surface of the outer casing 201 is also equipped with a protective shell 6. The drive motor 2041, the drive wheel 2044, the transmission wheel 2043, the belt 2045, the worm gear 2042 and the driven gear 2046 are all located inside the protective shell 6.

[0034] The drive motor 2041, drive wheel 2044, transmission wheel 2043, belt 2045, worm gear 2042 and driven gear 2046 are completely enclosed by the protective shell 6, which effectively isolates external pollutants such as rainwater, dust, and sand, prevents key components from rusting or clogging, and extends the service life of the drive components.

[0035] In use, starting the drive motor 2041 causes its output to rotate the drive wheel 2044. The drive wheel 2044, via the belt 2045, drives the transmission wheel 2043 and the worm gear 2042 to rotate. Since the worm gear 2042 meshes with the driven gear 2046, the driven gear 2046 drives the first connecting shaft 2021 to rotate. The first connecting shaft 2021 then drives the spur gear 2024 to rotate, causing the rack 2025 meshing with it to move vertically. The rack 2025 is pushed by the support base 2026. As the solar panel 3 rises, the first connecting shaft 2021 rotates, and the first connecting rod 2022 fixed on it rotates with the shaft, pushing the shading plate 203 to slide outward along the opening of the outer shell 201 through the hinge point. The second connecting rod 2028 on the second connecting shaft 2027 rotates synchronously, so that the opening on the outer shell 201 is gradually exposed. During the rising process, the solar panel 3 extends completely from the internal space of the outer shell 201 to the outside, maximizing the exposure range to sunlight. The shading plate 203 slides completely to both sides of the opening and no longer covers the solar panel 3, ensuring unobstructed light intake.

[0036] When the weather is severe, the drive motor 2041 is reverse-started, causing it to rotate in reverse. This reverses the rotation of the drive motor 2041, which in turn drives the transmission wheel 2043 and the worm gear 2042 to rotate in the opposite direction via the belt 2045. This causes the worm gear 2042 to drive the driven gear 2046 to rotate in the opposite direction, which in turn drives the first connecting shaft 2021 to rotate in the opposite direction. When the first connecting shaft 2021 rotates in the opposite direction, the spur gear 2024 on it drives the meshing rack 2025 to move downwards in the vertical direction. The rack 2025 is supported by the support base 202. 6 drives the solar panel 3 to descend synchronously and gradually retract into the outer casing 201. When the first connecting shaft 2021 rotates in the opposite direction, the first connecting rod 2022 rotates in the opposite direction with the first connecting shaft 2021 at the same time. Through the hinge point, the shielding plate 203 is pulled to slide towards the center along the opening of the outer casing 201. The second connecting rod 2028 on the second connecting shaft 2027 rotates in the opposite direction synchronously, assisting the shielding plate 203 to close smoothly and cover the opening. At this time, the solar panel 3 completely returns to the interior of the outer casing 201 to avoid the impact of severe weather.
