Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration units, in particular to a refrigeration unit for a refrigerated vehicle. Background Art

[0002] Refrigeration units for refrigerated trucks are specially designed equipment to keep goods within a suitable temperature range during transportation. These units are usually installed on vans, trucks or containers to ensure that goods, especially sensitive goods such as food and medicines, are kept at appropriate temperature conditions to prevent corruption or deterioration. However, poor road conditions during vehicle driving may cause damage to the refrigeration unit.

[0003] The vibration caused by the vehicle during driving and the vibration caused by the operation of the compressor in the refrigeration unit can easily affect the stability of the refrigeration unit and easily cause resonance. The resonance generated will increase the vibration generated during the operation of the refrigeration unit, causing damage to various components in the refrigeration unit and affecting its service life.

[0004] The existing patent (publication number: CN218410421U) is a refrigeration unit for a refrigerated vehicle. The utility model has a shock-absorbing assembly composed of multiple shock-absorbing units arranged around an installation chamber between a support plate and an outer shell, and a first shock-absorbing spring is arranged between a connecting rod between the support plate and a connecting seat, and a second shock-absorbing spring is arranged in a guide chamber between a limiting portion and the outer shell, so as to limit the downward and upward movement of the support plate and absorb the downward and upward forces on the support plate; thereby achieving multi-directional vibration absorption, not only avoiding the generation of resonance, but also protecting the refrigeration unit well, especially avoiding damage to the refrigeration unit body when subjected to high-impact vibration.

[0005] In view of the above problems, existing patents have provided solutions. However, in actual use, it is extremely unstable to use springs alone to buffer and reduce shock of the refrigeration unit. At the same time, the installation position of the spring will bear the entire weight of the refrigeration unit, resulting in a decrease in the elastic function of the spring and a shortened service life. The reduced buffering and shock-absorbing effect increases the probability of resonance and cannot provide good buffering protection for the refrigeration unit.

[0006] Therefore, a refrigeration unit for a refrigerated vehicle is proposed. Summary of the invention

[0007] The purpose of the utility model is to provide a refrigeration unit for a refrigerated vehicle, which can solve the problem that in the actual use process, the existing refrigeration unit is only buffered and damped by a spring, which is extremely unstable, and the installation position of the spring will bear the entire weight of the refrigeration unit, resulting in a decrease in the elastic function of the spring, a decrease in the service life, a decrease in the buffering and damping effect, an increase in the probability of resonance, and a failure to provide good buffering protection for the refrigeration unit.

[0035] When the refrigeration unit body 203 is subjected to external vibration during operation, the damper 204 at the bottom of the refrigeration unit body 203 can drive the refrigeration unit body 203 to slide inside the installation bin 202 for buffering and shock absorption to prevent the occurrence of resonance.

[0039] When in use, by rotating the rotating disk 603 on one side of the shell 1, the pulling rope 604 can be driven to retract into the inside of the rotating disk 603. At this time, the pulling rope 604 will pull the adjusting leaf 602 to rotate and tilt on one side of the rotating rod 601. By adjusting the inclination angle of the leaf 602, the air outlet direction of the air outlet 201 can be changed, so that the air outlet direction can be controlled. Through the mounting plate 701 and the mounting groove 702, the shell 1 can be more conveniently installed inside the box.

[0042] By adopting the above technical solution, the problem of poor existing buffering and shock absorption effect is solved.

[0043] Working principle: When the present application is in use, firstly, when the refrigeration unit body 203 is subjected to external vibration during operation, the damper 204 at the bottom of the refrigeration unit body 203 can drive the refrigeration unit body 203 to slide inside the installation bin 202 for buffering and shock absorption to prevent the occurrence of resonance, and at the same time drive the sliding plate 303 inside the sliding groove 302 to improve the stability of the refrigeration unit body 203, and when vibration comes, drive the guide rod 402 to slide in the guide groove 401 to position the refrigeration unit body 203 to prevent the refrigeration unit body 203 from escaping from the installation bin 202, while the guide rod 402 slides inside the guide groove 401, the stabilizing plate 301 squeezes the guide spring 403, triggering the rebound force of the guide spring 403 to rebound and correct the position of the stabilizing plate 301, so that the stabilizing plate 301 drives the refrigeration unit body 203 to quickly return to its original position, and when the refrigeration unit body 203 slides inside the installation bin 202 When sliding and damping, the sliding column 502 will be pushed to slide inside the sliding cylinder 501, and then the auxiliary spring 503 will be used for buffering and damping, thereby improving the buffering and damping effect of the refrigeration unit body 203 after being impacted. The refrigeration unit body 203 delivers cold air through the air outlet 201 for refrigeration. By rotating the rotating disk 603 on one side of the shell 1, the pulling rope 604 can be driven to retract and rotate inside the rotating disk 603. At this time, the pulling rope 604 will pull the adjusting leaf 602 to rotate and tilt on one side of the rotating rod 601. By adjusting the inclination angle of the leaf 602, the air outlet direction of the air outlet 201 is changed, so that the air outlet direction is controlled. Through the mounting plate 701 and the mounting groove 702, the shell 1 can be more conveniently installed inside the box. Starting the heat dissipation fan 9 can discharge the heat generated by the operation of the refrigeration unit body 203 inside the shell 1, thereby improving the stability of the refrigeration unit body 203 during operation and improving the controllability of the air outlet direction of the refrigeration unit body 203.
