Description

Technical Field

[0001] The invention relates to the technical field of armrest boxes, in particular to an automobile electric armrest box. Background Art

[0002] Cars have become an indispensable part of our daily lives. On the basis of conveniently and safely taking people to their destinations, they have developed more comfortable, convenient, and user-friendly configuration applications, and even operation-free experience functions such as intelligent voice and automatic driving; As people spend more time with cars, there is a greater demand for in-car storage and entertainment functions. The advancement of electrification, intelligence, and automation also frees up more functional areas for storage and more time for entertainment. Refrigerators, color TVs, and large sofas have become the "standard configuration" of today's cars. Among the many storage designs, the car armrest box is a car accessory installed between two seats, which belongs to the car interior system. The original intention of its humanized design is to enable car drivers to place their arms when driving for a long time, so that their arms can get an effective rest without being sore, numb, or stiff. With the continuous development of manufacturing technology and the continuous improvement of production processes, the armrest box has a storage function, such as storing small items such as beverages and water cups, so that the driver can easily get these small items when needed. Due to the different usage habits between the north and the south, northerners mostly call it an armrest box, while southerners mostly call it a hand armrest box. There are also central armrest boxes, storage boxes, and storage boxes. For drivers, the most commonly used is the storage armrest box designed in the auxiliary instrument. It has a large volume, is easy to take, and has various forms. Whether driving long or short distances, the armrest box is indispensable. It not only has a storage function, but also has the function of an armrest. When the driver is tired of driving, the driver can put his right arm on the storage armrest box to relieve driving fatigue.

[0003] Currently, among the numerous armrest box designs, most armrest box covers are basically flipped open to take out and put in items in the armrest box, whether flipped from front to back or to the side. Even the latest design divides the armrest box cover into two halves and opens to both sides through buttons. Each of these designs requires the driver to make a large movement, and it is not very convenient to take and put items. At the same time, the existing armrest box cannot reduce the friction of the moving part of the armrest box when opening or closing, so that the armrest box is prone to make noise when opening or closing when used for a long time. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides an electric armrest box for a car. By pressing an open button, the armrest box cover automatically rolls up, the armrest box is opened, and items are taken and placed. By pressing the close button again, the armrest box cover automatically unfolds and the armrest box is closed. After the armrest box cover is closed, a storage slot can be formed to place lightweight items such as mobile phones, thereby expanding the storage space. The device is mainly composed of an armrest box, an armrest box cover body, a roller blind, a roller blind shaft, a rotating shaft, a driving wheel, a shaft end retaining ring, a flat key, an open button, a close button, a flat key and a stepping motor. Without changing the space occupied by the original armrest box, the storage space of the armrest box can be increased to the maximum extent. It has a compact structure, strong practicality, low cost and a wide range of applications. A stepper motor is used to drive the reel to rotate forward and reverse through gear transmission, thereby driving the opening and closing of the armrest box cover. The movement of the entire mechanism is within the scope of its own structure, and does not affect other parts and the posture of the driver's arm rest. The opening form can be controlled by a physical switch, an induction switch, a large-screen switch or voice, with a variety of choices and convenient control. The oil inlet pipe is used to pour external lubricating oil into the interior of the storage box, and the lubricating oil in the storage box can be adsorbed by the adsorption cotton. When the opening button is pressed, the electric push rod is used The electrical connection with the opening button allows the electric push rod to be retracted to push the slide plate downward. When the slide plate moves, it can drive the connecting rod and the pressure plate to move, so that the pressure plate can extend into the interior of the storage box to squeeze the adsorption cotton. When the adsorption cotton is squeezed by external force, the lubricating oil absorbed in the adsorption cotton can be discharged into the interior of the collection box through the oil outlet pipe. The through hole is used to allow the lubricating oil in the collection box to drip onto the inside of the brush. Since the brush fits the upper surface of the driving wheel, when the driving wheel rotates, the lubricating oil in the brush can be applied to the surface of the driving wheel, so that it can lubricate the meshing rotation of the driving wheel and the rotating shaft, thereby reducing the friction between the driving wheel and the rotating shaft, and reducing the noise when the roller shutter is opened or closed.
