Description
Technical Field
[0001] The utility model relates to the technical field of testing equipment, and more specifically to testing equipment for a vehicle refrigerator. Background Art
[0002] Car refrigerators use the traditional technology of traditional refrigerators. They are small in size and have a low cooling temperature of -18 degrees 10 degrees. They have high cooling efficiency and can make ice and preserve food. They are large in size and are the mainstream direction of the development of car refrigerators. The appearance design of car refrigerators is usually very exquisite, and the color matching and material use are very sophisticated. They can not only add a sense of fashion and personalized style to the car, but also have a good decorative effect. Using a car refrigerator in the car can conveniently store and preserve food and drinks. Especially for users who like to drive out or outdoor activities, car refrigerators are one of the indispensable equipment.
[0003] Existing car refrigerators are generally placed inside the storage box in front of the co-pilot seat. The compressor, the core component of the car refrigerator, will produce self-vibration if the compressor is unevenly stressed during operation, causing the internal parts to be affected by varying degrees of vibration. This vibration may cause the parts to loosen, wear or be damaged, thus affecting the normal operation and service life of the refrigerator. In addition, existing car refrigerators will be subject to bumps and vibrations from the road during driving. If the refrigerator's pressure resistance is insufficient, it may cause damage or leakage. Utility Model Content
