Description

Technical Field

[0001] The utility model relates to the technical field of carriage protection, in particular to a protection structure for a refrigerated truck carriage. Background Technique

[0002] With the rapid development of the modern cold chain logistics industry, refrigerated trucks have become key tools for transporting fresh food, pharmaceutical products, and other temperature-sensitive goods. However, during transportation, the refrigerated truck carriage is easily affected by external impacts, vibrations, and other factors, resulting in carriage deformation, damage to goods, and even affecting the thermal insulation performance of the carriage, which poses higher requirements for the stability and safety of refrigerated transportation. Therefore, in order to ensure the safe transportation of goods and the durability of the carriage, there is an urgent need for a protection structure that can effectively absorb impacts, disperse stress, and reduce damage to the carriage body caused by impacts.

[0003] An existing protection structure for a refrigerated truck carriage (Publication No.: CN220809586U) has at least the following drawbacks: The above device wraps three sides of the carriage body through the cooperation of a main fixing clip and a secondary fixing clip. When the carriage body is collided and impacted, the impact force is absorbed by the structural strength of the main fixing clip and the secondary fixing clip itself. Through the setting of a compression spring, the displacement of the secondary fixing clip is buffered, so as to offset the impact force with its own elastic force. However, when the carriage is impacted, its edge corners are extremely prone to deformation and damage. When the device protects the three sides, it is difficult to effectively protect the edge corners of the carriage. Moreover, during the driving of the vehicle, the compression spring may cause frequent displacement of the secondary fixing clip when dealing with continuous vibrations and dynamic impacts, thus affecting the stability of the fixing frame, and further resulting in poor protection effect of the structure. For this reason, we propose the present utility model. Content of the Utility Model

[0004] The purpose of the present utility model is to solve the drawbacks existing in the prior art, and to propose a protection structure for a refrigerated truck carriage.

[0005] In order to achieve the above purpose, the present utility model adopts the following technical scheme:

[0006] A protection structure for a refrigerated truck carriage, including a vehicle board, the top surface of the vehicle board is fixed with a carriage body, a buffer structure is arranged on the outer wall of the carriage body, the buffer structure includes two support rods fixed on the top surface of the vehicle board, the support rods are in a U shape, two movable rods are arranged on the top surfaces of the two carriage bodies, lifting rods are arranged on both the left and right sides of the carriage body, both ends of the movable rods and the lifting rods are slidably arranged on the two support rods, and a plurality of elastic arc plates are fixed between the two movable rods and the lifting rods on the left and right sides respectively.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations

[0023] As Figures 1 - 4 shown, a protection structure for the carriage of a refrigerated truck includes a vehicle floor 1. The top surface of the vehicle floor 1 is fixed with a carriage body 2. A buffer structure is provided on the outer wall of the carriage body 2. The buffer structure includes two support rods 201 fixed on the top surface of the vehicle floor 1. The support rods 201 are in a U shape. Two movable rods 202 are provided on the top surface of the two carriage bodies 2. Lifting rods 203 are provided on both the left and right sides of the carriage body 2. The two ends of the movable rods 202 and the lifting rods 203 are respectively slidably arranged on the two support rods 201. A number of elastic arc plates 204 are fixed between the two movable rods 202 and the lifting rods 203 on the left and right sides respectively

[0024] In this embodiment, a plurality of protective rods 205 are fixed between the two support rods 201. A plurality of first spring dampers 206 are fixed between each of the two movable rods 202 and the adjacent protective rod 205 respectively. A plurality of second spring dampers 207 are fixed between each of the two lifting rods 203 and the adjacent protective rod 205 respectively. The first spring dampers 206 and the second spring dampers 207 are both prior arts. Through the arrangement of the buffer structure, when the carriage body 2 is impacted, a plurality of elastic arc plates 204 protect the two top edges of the carriage body 2. When the top edges are impacted, the elastic arc plates 204 deform and extend to absorb energy. When the pressure disappears, the elastic arc plates 204 will return to their initial forms relying on their own elasticity. When the elastic arc plates 204 extend, the movable rods 202 and the lifting rods 203 move towards the protective rod 205 under the influence of the elastic arc plates 204, and the first spring dampers 206 and the second spring dampers 207 are compressed, thereby improving the buffering capacity of the elastic arc plates 204. At the same time, the sliding of the movable rods 202 and the lifting rods 203 on the support rods 201 reduces the direct impact and absorbs part of the kinetic energy, converting part of the impact kinetic energy into sliding friction energy, so as to reduce the impact force directly transmitted to the carriage body 2 and prevent the carriage body 2 from suffering structural damage, thereby realizing the protection of the carriage body 2, reducing the possibility of damage to the edge corners of the carriage body 2 when it is impacted, and improving the protection effect of the carriage body 2.

[0025] In this embodiment, a plurality of protective rods 205 are evenly distributed on three sides of the carriage body 2. A plurality of first spring dampers 206 and a plurality of second spring dampers 207 are both evenly distributed along the length direction of the protective rods 205. The plurality of protective rods 205 form a protection on three sides of the carriage body 2, improving the protection effect of the carriage body 2.

[0026] In this embodiment, a protective shell 3 is fixed on the top surface of the vehicle floor 1. The carriage body 2 is located inside the protective shell 3. The protective shell 3 further protects the carriage body 2 and at the same time shields the buffer structure to prevent the buffer structure from being exposed to the outside and corroded.

[0027] In this embodiment, two protective pads 301 are fixed inside the protective shell 3. Both of the two protective pads 301 are fixed to the carriage body 2. The protective pads 301 are made of rubber, and the three sides of the carriage body 2 near the front and rear ends can be protected through the protective pads 301.

[0028] In this embodiment, several positioning sleeves 4 are fixedly installed inside the protective shell 3, and several positioning shafts 401 are fixedly installed on the top surface of the vehicle floor 1. The positioning shafts 401 are slidably inserted into the insides of the positioning sleeves 4. When the staff installs the protective shell 3 on the vehicle floor 1, the positioning shafts 401 can be first inserted into the positioning sleeves 4 to pre-position the position of the protective shell 3 on the vehicle floor 1, and then the protective shell 3 is welded and fixed.

[0029] Working principle: During use, when the carriage body 2 is impacted, several elastic arc plates 204 protect the two top edges of the carriage body 2. When the top edges are impacted, the elastic arc plates 204 deform and extend to absorb energy. When the pressure disappears, the elastic arc plates 204 will return to their initial form by relying on their own elasticity. When the elastic arc plates 204 extend, the movable rods 202 and the lifting rods 203 move towards the protective rods 205 under the influence of the elastic arc plates 204, and the first spring dampers 206 and the second spring dampers 207 are compressed, so as to improve the buffering capacity of the elastic arc plates 204. At the same time, the sliding of the movable rods 202 and the lifting rods 203 on the support rods 201 reduces the direct impact and absorbs part of the kinetic energy, converting part of the impact kinetic energy into sliding friction energy, thereby reducing the impact force directly transmitted to the carriage body 2 and preventing the carriage body 2 from suffering structural damage. Several protective rods 205 form a protection on three sides of the carriage body 2, improving the protection effect of the carriage body 2. The protective shell 3 further protects the carriage body 2, and at the same time shields the buffer structure to prevent the buffer structure from being exposed to the outside and corroded. The protective pads 301 can protect the positions on three sides of the carriage body 2 near the front and rear ends. When the staff installs the protective shell 3 on the vehicle floor 1, the positioning shafts 401 can be first inserted into the positioning sleeves 4 to pre-position the position of the protective shell 3 on the vehicle floor 1, and then the protective shell 3 is welded and fixed.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
