Description

Technical Field

[0001] This utility model relates to the field of tricycle technology, specifically a refrigerated transport tricycle for freezers. Background Technology

[0002] Electric tricycles are three-wheeled transport vehicles powered by batteries and driven by motors, used for hauling goods or people. They employ tubular, high-capacity, left and right-side lined, deep-discharge, traction-type batteries, capable of withstanding continuous discharge during extended operation. The batteries typically last for two years without capacity reduction. In related technologies, when using electric tricycles for street vending, a portable refrigerator is often placed in the tricycle's cargo compartment.

[0003] A search revealed a patent with publication number CN218431554U, which discloses an electric tricycle with a vehicle-mounted refrigerator, comprising: a vehicle body; a cargo box, the bottom of which is fixedly connected to the top of the vehicle body; and an adjustment assembly, the bottom of which is fixedly connected to the top of the cargo box. The adjustment assembly includes a storage rack, the bottom of which is fixedly connected to the top of the cargo box. An adjustment rod is slidably connected to the inner side of the storage rack, and a sliding sleeve is fixedly connected to the left side of the storage rack. Moving a pull ring moves a connecting rod to the left, which in turn moves a limiting ring to the left, causing a spring to contract. This movement of the connecting rod disconnects the storage rack from the adjustment rod, thus lowering the height of the rain shelter. The operation is simple and convenient, effectively improving the flexibility of the rain shelter and allowing the electric tricycle to maneuver flexibly through narrow alleys.

[0004] In the aforementioned existing technologies, the vehicle-mounted freezer directly fills the entire carrying area of ​​the vehicle compartment, making it difficult to evenly distribute the goods inside. If the goods are concentrated on one side of the freezer, the overall center of gravity of the electric tricycle will be biased to one side. When the driver is driving in a straight line, the direction is prone to deviating, requiring the driver to constantly correct the direction to maintain balance. Especially during turns, the shift in the center of gravity will significantly increase the risk of tilting. If the road surface is bumpy, it may even cause the tricycle to overturn. At the same time, the unstable center of gravity will also accelerate the wear and tear of the vehicle body parts, shorten the service life of the electric tricycle, and increase maintenance costs. Secondly, when vendors need to retrieve goods from the back of the freezer, they must first pry up the stacked goods on top to reach the goods on the bottom. This process not only disrupts the neat arrangement of the goods inside the freezer, causing extra time for subsequent sorting, but more importantly, the weight of the goods on top will continuously press on the goods on the bottom. For fresh fruits, long-term compression will cause the peel to break and the flesh to spoil. For packaged cooked food, compression may cause the packaging to deform and the seal to fail, leading to the risk of food contamination. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or existing refrigerated transport tricycles, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A refrigerated transport tricycle for freezers includes a vehicle body, a compartment fixedly installed on the top of the vehicle body, a first refrigeration mechanism and a second refrigeration mechanism for convenient retrieval of goods evenly arranged along a straight line inside the compartment, and the weight distribution center of the first refrigeration mechanism and the second refrigeration mechanism coincides with the central axis of the compartment.

[0009] As a preferred embodiment of the refrigerated transport tricycle of the present invention, the first refrigeration mechanism includes a placement frame fixedly installed in the compartment and evenly distributed along the length of the compartment. The inner wall of the placement frame is adapted to the outer wall of the freezer. The first freezer for refrigerating goods can be detachably placed in the placement frame.

[0010] As a preferred embodiment of the refrigerated transport tricycle for freezers described in this utility model, the first freezer is configured as a long rectangular structure.

[0011] As a preferred embodiment of the refrigerated transport tricycle described in this utility model, the evenly distributed placement frames are correspondingly set at the four corners of the vehicle compartment.

[0012] As a preferred embodiment of the refrigerated transport tricycle described in this utility model, the second refrigeration mechanism includes a pair of second freezers symmetrically and fixedly installed on the central axis of the carriage, the symmetrical center of the two second freezers coincides with the central axis of the carriage, and the interior of the second freezers is provided with a freezing cavity for layered refrigeration of goods.

[0013] As a preferred embodiment of the refrigerated transport tricycle described in this utility model, the second freezer has symmetrically hinged doors on the outer wall of the side away from the central axis of the carriage, and the hinge direction of the doors faces both sides of the carriage.

[0014] As a preferred embodiment of the refrigerated transport tricycle for freezers described in this utility model, a movable basket is slidably installed in the freezing cavity of the second freezer along the horizontal direction, and the movable basket can be pulled out from the freezing cavity.

Furthermore, the multiple first freezers independently store different goods, limiting the amount of goods that can be stacked. The movable baskets of the second freezers, along with the partition blocks, divide the cargo into independent areas. Both design minimize the pressure on the bottom cargo, providing excellent protection for the goods during transport. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Example

[0031] Please see Figures 1-5 This utility model provides a technical solution: a refrigerated transport tricycle for freezers. The tricycle is based on a vehicle body 1. A cargo box 2 is fixedly installed on the top of the vehicle body 1. A first refrigeration mechanism 3 and a second refrigeration mechanism 4 are evenly arranged along a straight line inside the cargo box 2. The weight distribution center of the first refrigeration mechanism 3 and the second refrigeration mechanism 4 coincides with the central axis of the cargo box 2. This design is the core of solving the problem of center of gravity shift. By concentrating the weight of all refrigeration mechanisms on the central axis of the cargo box, the weight is prevented from shifting to one side, ensuring the stability of the center of gravity when the tricycle is in motion and reducing the risk of directional deviation and tilting.

[0032] The first refrigeration unit 3 is used to store bulk, infrequently accessed goods. Its structure includes placement frames 5 fixedly installed inside the carriage 2 and evenly distributed along the length of the carriage. The inner wall of the placement frames 5 is adapted to the outer wall of the freezer. The placement frames 5 provide stable installation positioning for the freezer, preventing it from sliding inside the carriage when the tricycle is bumpy. A first freezer 6 is detachably placed inside the placement frames 5. The first freezer 6 is designed as a long rectangular structure, and its detachable design facilitates individual cleaning, maintenance, or replacement. The evenly distributed placement frames 5 are correspondingly positioned at the four corners of the carriage 2, which are symmetrically located equidistant from the central axis. Placing the first freezers 6 at the four corners allows the weight of each freezer to be evenly distributed on both sides of the carriage, and the center of gravity of all freezers coincides with the central axis of the carriage. Even if the weight of the goods in the multiple first freezers 6 is slightly different, the impact on the overall center of gravity is greatly reduced because they are distributed at the four corners. In addition, the independent design of the first freezers 6 also solves the problem of goods being squeezed, that is, each first freezer 6 stores one type of goods separately, avoiding the mixing and stacking of different goods. At the same time, the capacity of a single freezer is moderate, the amount of goods stacked is limited, and the lower layer of goods will not be excessively squeezed by the upper layer of heavy goods, which is especially suitable for goods with fragile packaging.

[0033] The second refrigeration unit 4 is used to store frequently accessed and easily damaged goods. Its structure includes a pair of second freezers 7 symmetrically fixedly installed on the central axis of the carriage 2. The centers of symmetry of the two second freezers 7 coincide with the central axis of the carriage 2, further enhancing the overall balance and preventing the center of gravity from shifting due to the weight of one side of the second freezer 7. A sealing door 8 is symmetrically hinged to the outer wall of the second freezer 7 on the side away from the central axis of the carriage 2, with the hinge direction of the sealing door 8 facing both sides of the carriage 2. Vendors can open the sealing door 8 from both sides of the carriage to retrieve goods without having to go around to the rear of the carriage, significantly improving convenience, especially in crowded market environments. The second freezer 7 has a freezing chamber 9 inside, and a movable basket 10 is slidably installed horizontally inside the freezing chamber 9. The movable basket 10 can be pulled out from the freezing chamber 9, allowing vendors to retrieve goods without... By simply prying up the upper layer of goods, the mobile basket 10 can be pulled out directly to access all the goods, solving the problem of having to rummage through the upper layer of goods to retrieve them in the prior art. A pair of baffles 12 are symmetrically fixed along the length direction on the top surface of the mobile basket 10. The baffles 12 can prevent the goods from sliding off the sides of the basket when the mobile basket 10 is pulled out, thus avoiding damage from falling goods. A pair of handles 13 are symmetrically fixed along the width direction on the inner wall of the top surface of the mobile basket 10. The handles 13 make it easy for vendors to grip and pull the mobile basket 10, especially when the goods in the mobile basket 10 are heavy, making it easier to pull. Several evenly distributed isolation blocks 11 are fixedly fixed on the inner wall of the mobile basket 10 and the inner wall of the freezing chamber 9, respectively. The isolation blocks 11 can divide the space inside the mobile basket 10 and the freezing chamber 9 into multiple independent small areas, preventing the goods from colliding and squeezing with each other.

[0034] In this design, the first freezers 6 are distributed at the four corners of the carriage, and the second freezers 7 are symmetrically positioned along the central axis. The weight center of all refrigeration units coincides with the central axis of the carriage. Even if there are weight differences among the multiple first freezers 6, the impact of a single first freezer 6 on the overall center of gravity is significantly reduced due to their distribution at the four corners. This ensures directional stability during driving, reduces the risk of lateral tilting when turning, reduces tire wear on one side, extends tire life, and lowers maintenance costs. Furthermore, the multiple first freezers 6 can independently store different goods, limiting the amount of goods that can be stacked. The movable basket 10 of the second freezer 7, together with the isolation block 11, divides the cargo into independent areas. Both of these components have low compression on the bottom cargo, providing excellent protection for the goods during transportation.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
