Technical Field
[0001] This utility model belongs to the field of transportation equipment, and in particular relates to a shockproof transportation device for campus catering vehicles. Background Technology
[0002] A transport unit is a catering facility specifically designed to provide catering services to different locations. It is mainly used to safely and efficiently transport ingredients to various food preparation locations to ensure that diners can enjoy fresh and healthy food.
[0003] Traditional transport equipment typically employs a structural design where the container is placed directly on a chassis. Functionally, it mainly focuses on simple food storage or temperature control. However, during actual transport, the chassis inevitably passes through roads with complex conditions, resulting in varying degrees of vibration. This vibration can easily damage fragile or irregularly shaped food items inside the container during transport, leading not only to food waste and increased catering operating costs but also potentially affecting the final variety and quality of the prepared meals.
[0004] Therefore, there is a particular need for a shockproof transportation device for campus catering vehicles to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of traditional transportation devices, which cause damage to fragile or irregularly shaped food items inside the compartment due to vibration when the vehicle frame travels on complex road conditions, resulting in food waste, increased catering operation costs, and affecting the final types and quality of prepared meals, this utility model provides a shockproof transportation device for campus catering vehicles.

Each third spring is sleeved on the outside of each second guide rod, with both ends fixedly connected to the corresponding housing and the corresponding latch. The control display screen is installed on one side of the middle of the other door and is electrically connected to the electromagnet.
[0008] As a preferred technical solution of this utility model, it also includes a sliding seat, a support roller and a second spring. The sliding seat is slidably disposed at the geometric center of the base, and the support roller is rotatably disposed on the upper part of the sliding seat. The highest point of the roller surface extends beyond the sliding seat and forms a tight rolling contact with the bottom surface of the box. The second spring is sleeved on the cylindrical surface of the sliding seat, and its two ends are fixedly connected to the sliding seat and the base respectively.
[0009] As a preferred technical solution of this utility model, it also includes a cooler and a temperature sensor. The cooler is installed on the other side of the compartment, and the temperature sensor is installed at the geometric center of the top of the compartment.

[0027] Example: A shockproof transportation device for campus meal delivery vehicles, such as Figures 1-9 As shown, the enclosure includes a body 1, a door 2, a base 3, a damper 4, a bushing 5, a first guide rod 6, a first spring 7, a rubber block 8, a hinge block 9, a shock absorber 10, a support plate 11, a slide rod 12, a smart door lock assembly, and a sealing strip 21. The body 1 is placed on the base 3, and its internal structure can be customized according to the storage requirements of the food, such as setting different sized compartments to meet the storage requirements of different types and quantities of food. Two doors 2 are arranged side by side and rotate vertically on the front side of the body 1, and they contact each other to seal the opening on the front side of the body 1. Each door 2 is equipped with a handle on its front side. Eight bushings 5 are welded around the base 3, and eight dampers 4 are welded around the base 3. The eight dampers 4 are located below the eight bushings 5. The fixed end of each damper 4 is fixedly connected to the base 3, while the movable end forms a sliding contact with the body 1. A first guide rod 6 is slidably installed inside each bushing 5. An annular plate is located in the middle of the first guide rod 6, and both its inner and outer ends pass through the bushing 5. A set of first springs 7 is installed inside each bushing 5, with each set containing two first springs 7. The two ends of the first spring 7 are fixedly connected to the inner wall of the corresponding bushing 5 and the corresponding first guide rod 6, respectively. A rubber block 8 is glued to the inward end of each first guide rod 6. The side of the rubber block 8 away from the first guide rod 6 is in direct contact with the body 1. Through the elastic buffering characteristics of the rubber block 8, hard contact between the body 1 and the first guide rod 6 can be effectively avoided. In addition, a row of grooves is opened on the side of the rubber block 8 that contacts the body 1. These grooves can increase the roughness of the contact surface, thereby effectively increasing the friction between the rubber block 8 and the body 1 and ensuring stable contact between the two. Qualitatively, four hinge blocks 9 are arranged along a rectangular direction and are bolted to the four corners of the bottom of the compartment 1. Two support plates 11 are welded to the four corners of the lower part of the base 3. A slide rod 12 is slidably arranged between each pair of support plates 11. Each shock absorber 10 is rotatably arranged at the middle position of each slide rod 12, and its upper end is rotatably connected to the vertically aligned hinge block 9. The intelligent door lock assembly is arranged between the two compartment doors 2. The vertical sides of the two compartment doors 2 that come into contact with each other are wrapped with sealing strips 21 to ensure the sealing performance between the compartment doors 2.
[0028] like Figure 1 , Figure 8 and Figure 9 As shown, the smart door lock assembly includes a housing 18, an electromagnet 181, a latch 182, a second guide rod 19, a third spring 191, and a control display screen 20. Two housings 18 are welded vertically to the left side door 2. Each housing 18 contains an electromagnet 181. Each second guide rod 19 is slidably mounted on each housing 18 and passes through and is slidably connected to the corresponding electromagnet 181. Both ends of each second guide rod 19 extend to the outside of the housing 18. Each latch 182 is attached to the right end of each second guide rod 19. Made of magnetic materials, such as pure iron or silicon steel, the right side door 2 has two slots 183 distributed vertically. Two locking tongues 182 are engaged with the two slots 183 one by one, thereby locking the two doors 2. Each third spring 191 is sleeved on the outside of each second guide rod 19, and its left and right ends are fixedly connected to the corresponding outer shell 18 and the corresponding locking tongue 182, respectively, to provide a reset force for the second guide rod 19. The control display screen 20 is bolted to the left side of the middle of the right side door 2 and is electrically connected to the electromagnet 181.
[0029] like Figure 3 , Figure 4 and Figure 6 As shown, it also includes a sliding seat 13, a support roller 131, and a second spring 14. The sliding seat 13 is slidably disposed at the geometric center of the base 3. The support roller 131 is rotatably disposed on the upper part of the sliding seat 13, with the highest point of its roller surface extending beyond the sliding seat 13 and forming a tight rolling contact with the bottom surface of the chamber 1. A rubber pad is fitted on the roller surface of the support roller 131 to reduce the hard contact between the bottom surface of the chamber 1 and the top surface of the support roller 131. The second spring 14 is fitted on the cylindrical surface of the sliding seat 13, with its upper and lower ends fixedly connected to the sliding seat 13 and the base 3, respectively, to provide a reset force for the sliding seat 13.
[0030] like Figure 7 As shown, it also includes a cooler 15 and a temperature sensor 17. The cooler 15 is bolted to the rear side of the compartment 1, and the temperature sensor 17 is bolted to the geometric center of the top of the compartment 1. Both the cooler 15 and the temperature sensor 17 are electrically connected to the control display screen 20.
[0031] like Figure 7 As shown, it also includes lighting lamps 16. Two lighting lamps 16 are arranged side by side and bolted to the inner top of the compartment 1 and electrically connected to the control display screen 20. They can provide sufficient and uniform lighting for the interior of the compartment 1, making it convenient for staff to view the items inside the compartment 1 when the compartment door 2 is opened.
[0032] When this device is needed, the operator first places the base 3 stably on the frame. After placing it, the operator uses straps to secure the base 3. Then, the operator controls the electromagnet 181 to be energized through the control display screen 20. When the electromagnet 181 is energized, it generates an attractive force, which pulls the locking tongue 182 to move to the left, causing it to disengage from the slot 183. As the locking tongue 182 moves, the third spring 191 is compressed and stores elastic potential energy, thereby unlocking the two doors 2.
[0033] Then, the staff rotates the two doors 2 forward to open the compartment 1, and puts the ingredients to be transported into the compartment 1 in an orderly manner. After placing the ingredients, they rotate the two doors 2 backward to close the compartment 1. Then, they control the electromagnet 181 to be de-energized through the control display screen 20. After the electromagnet 181 is de-energized, it no longer attracts the locking tongue 182. At this time, the third spring 191 returns to its original state, pushes the locking tongue 182 to the right to re-engage with the slot 183, and realizes the locking between the two doors 2, ensuring the sealing of the compartment 1 during transportation.
[0034] Finally, the staff started the refrigeration unit 15, which began to work and lowered the temperature inside the compartment 1. At the same time, the temperature sensor 17 detected the temperature inside the compartment 1 in real time and displayed the detected value on the control display screen 20. The staff could adjust the cooling intensity of the refrigeration unit 15 according to the temperature display on the control display screen 20 to ensure that the compartment 1 maintains a suitable low temperature environment to meet the needs of food preservation. Then, the vehicle frame was moved to transport the compartment 1 to the designated location.
[0035] During transportation, when the container 1 vibrates horizontally, it will impact the corresponding rubber block 8. The rubber block 8 undergoes elastic deformation, which in turn applies a force to the first guide rod 6 connected to it. Under the action of the force, the first guide rod 6 moves alternately outward and inward. When the first guide rod 6 moves, one of the first springs 7 connected to it alternately stretches and compresses, while the other first spring 7 alternately compresses and stretches. The first spring 7 absorbs and buffers the horizontal vibration energy through its own elastic deformation, reducing the impact of vibration on the container 1 and the food inside. At the same time, the damper 4 consumes the energy of the container 1 when it vibrates, further suppressing the vibration amplitude of the container 1, allowing the container 1 to recover to a stable state more quickly. In addition, when the container 1 vibrates horizontally, it pulls the hinge block 9 connected to it to vibrate. The hinge block 9 then transmits the vibration energy to the shock absorber 10 connected to it, further absorbing and dispersing the vibration energy, dispersing the horizontal vibration to the vertical direction, and reducing the swaying amplitude of the container 1 in the horizontal direction.
[0036] When the compartment 1 experiences vertical vibration during transportation, the support roller 131 moves downward under the intermittent pressure of the compartment 1, and the sliding seat 13 moves downward along with the support roller 131, stretching the second spring 14. After being stretched, the second spring 14 generates elastic potential energy. When the pressure of the compartment 1 on the support roller 131 stops, the second spring 14 returns to its original state, pushing the sliding seat 13 to drive the support roller 131 to move upward, thereby achieving vertical buffering and shock absorption of the compartment 1 and reducing the impact of vertical vibration on the food inside the compartment 1.
[0037] It is worth noting that when the compartment 1 vibrates horizontally, the horizontal vibration energy can be effectively dispersed to the vertical direction through the coordinated action of the hinge block 9 and the shock absorber 10. Similarly, when the compartment 1 vibrates vertically, the vertical vibration energy can also be dispersed to the horizontal direction through the coordinated action of the shock absorber 10 and the hinge block 9. This achieves the mutual conversion and buffering of vibration energy in multiple directions, reducing the impact of vibration on the compartment 1 and the food inside.
