Description

Technical Field

[0001] This utility model relates to the field of vehicle refrigerator technology, and in particular to a magnetically operated drawer vehicle refrigerator. Background Technology

[0002] In the field of in-vehicle refrigerators, the convenience and reliability of storage space are crucial. However, current in-vehicle refrigerator drawer systems have revealed many problems that urgently need to be solved in both design and practical application.

[0003] Some car refrigerator drawers rely on coil springs to power their pop-out mechanism. This design requires numerous fixing parts, significantly increasing the complexity of the overall structure, making assembly extremely cumbersome, and placing very high demands on the precision of each component. Furthermore, the coil springs are constantly in a state of frequent extension and contraction, severely testing their lifespan. Once the coil springs wear out or fail, the entire drawer pop-out function will be affected. The use of numerous parts not only increases mold development costs but also significantly raises processing and assembly costs, increasing the overall cost of the car refrigerator.

[0004] Some car refrigerators also choose motors as the power source for the drawer to pop out. Although motors can provide stable driving force, their high cost significantly increases the product cost. Moreover, in the confined space of a car, the noise generated by the motor and its actuators when unlocking is particularly noticeable, not only interfering with conversation between passengers but also seriously affecting the quiet environment inside the vehicle. Utility Model Content

[0005] The purpose of this invention is to provide a magnetically operated drawer-mounted refrigerator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution, which includes a box body, a box frame at the box body port, an inner liner inside the box body, a slide rail inside the inner liner, a storage drawer movably mounted on the slide rail, an inner drawer door panel on the outside of the storage drawer, an outer drawer door panel on the outside of the inner drawer door panel, magnet one, magnet two, and magnet three on the inner bottom surface of the inner drawer door panel, an electromagnet one corresponding to magnet one and an electromagnet two corresponding to magnet three on the bottom of the box frame, and a magnet four corresponding to magnet two on the bottom surface of the inner box.

[0007] As a preferred embodiment of this utility model, a Hall sensor is provided on the inner top surface of the box frame.

[0008] In a preferred embodiment of this utility model, the second magnet and the fourth magnet have opposite polarities.

[0009] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0010] This invention eliminates the need for numerous complex fixed parts and mechanical transmission components in traditional coil spring or motor drive systems by employing a Hall sensor in conjunction with electromagnets and magnetic blocks. Compared to coil spring drive systems, it eliminates the need for many fixed parts, reducing mold development costs associated with a large number of parts. Furthermore, the significant reduction in the types and quantities of parts leads to substantial cost reductions in raw material procurement and processing procedures. In the assembly process, fewer parts are required, greatly shortening assembly time and reducing labor costs, thereby achieving effective control over overall costs.

[0011] This invention eliminates mechanical power and actuation structures, relying primarily on the magnetic interaction between an electromagnet and a magnetic block during drawer opening and closing. When the drawer needs to be opened, a Hall sensor detects the closed state and controls the electromagnet to reverse its current, generating a repulsive force with the magnetic block to pop the drawer out. When closing, feedback from the Hall sensor causes the electromagnet to generate an attractive force to assist in closing the drawer. The entire process avoids direct impact between mechanical parts, greatly reducing noise generation and creating a quieter and more comfortable environment inside the vehicle, thus enhancing the user's driving experience.

[0012] This utility model's overall assembly structure eliminates the reliance on high-precision mechanical structures, greatly reducing the requirements for assembly personnel's professional skills and the assembly environment. Traditional coil spring drive systems have high precision requirements for each component, requiring a lot of time for debugging and calibration during assembly. However, this device, through a simple installation layout, has Hall sensors installed on the top surface inside the box frame, and electromagnets and magnetic blocks installed in corresponding positions on the bottom of the box frame and the bottom surface inside the drawer door panel. No complicated positioning and debugging process is required, and even assembly workers with relatively little experience can quickly and accurately complete the assembly work, greatly improving production efficiency.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] like Figures 1-3 As shown, the present invention proposes a magnetic drawer car refrigerator, which includes a main body. At the port of the cabinet 1, a frame 3 is installed, which protects and connects the cabinet 1. The cabinet 1 is provided with an inner liner 2, which provides stable space support for the installation and operation of the storage drawer 5. A slide rail 4 is installed in the inner liner 2, and the storage drawer 5 is movably connected to the inner liner 2 through the slide rail 4 to ensure that the drawer can be pulled out smoothly.

[0019] The storage drawer 5 consists of an inner drawer door panel 6 and an outer drawer door panel 14. The outer drawer door panel 14 is installed on the outside of the inner drawer door panel 6. Together, they form the main frame of the storage drawer 5. On the inner bottom surface of the inner drawer door panel 6, magnet 1 7, magnet 2 8, and magnet 3 9 are installed in sequence. These magnetic blocks are key components for realizing the automatic control of the drawer. Correspondingly, electromagnet 1 10 and electromagnet 2 11 are installed at the bottom of the frame 3. Electromagnet 1 10 corresponds to the position of magnet 1 7, and electromagnet 2 11 corresponds to the position of magnet 3 9. In addition, magnet 4 12 is installed on the inner bottom surface of the frame 3. It corresponds to the position of magnet 2 8 on the inner drawer door panel 6. Magnet 2 8 and magnet 4 12 are set in a way that opposite poles attract each other so as to generate a suction force to assist in closing the drawer during the closing process.

[0020] A Hall sensor 13 is installed on the inner top surface of the box frame 3. It can monitor the position change of the storage drawer 5 in real time and feed back the relevant signals to the control system, providing a basis for the action of the electromagnet, thereby realizing precise control of the drawer's opening and closing state.

[0021] Electromagnet 10 and electromagnet 21, as actuators that drive the movement of the drawer, are installed at the bottom of the frame 3 and correspond precisely to magnet 17 and magnet 39, respectively. By controlling the direction and magnitude of the current of the electromagnets, the repulsive or attractive force on the magnetic block is achieved, thereby controlling the drawer to open, close, and maintain a specific position.

[0022] Magnet 2 8 on the inner bottom surface of the drawer door panel 6 and magnet 4 12 on the inner bottom surface of the box frame 3 attract each other with opposite polarities. During the drawer closing process, the attraction generated by the two not only helps the drawer close smoothly, but also provides additional locking force when the drawer is closed, enhancing the stability of the drawer.

[0023] When the user presses the button to open the storage drawer 5, the system activates the Hall sensor 13 to detect the position of the drawer in real time. Once the Hall sensor 13 detects that the drawer is closed, the system will immediately send a command to electromagnet 10 and electromagnet 21 to reverse the direction of the current flowing through them. The magnetic field generated by electromagnet 10 and electromagnet 21 interacts with the corresponding magnet 17 and magnet 28 to form a repulsive force, causing the drawer to overcome static resistance and spring open a certain distance, thus starting the automatic door opening process.

[0024] During the drawer opening process, Hall sensor 13 continuously monitors the change in distance between the drawer and the cabinet and feeds the data back to the circuit program. As the opening distance gradually increases, the force required to overcome gravity and friction will change accordingly. Based on this feedback, the circuit program automatically adjusts and increases the current passing through electromagnet 10 and electromagnet 21. The magnetic force generated by the electromagnets is enhanced, thereby maintaining a relatively constant opening force on the drawer, ensuring that the drawer can pop out smoothly until it reaches the preset position and completes the opening action.

[0025] When the user manually pushes the drawer to close the door, the Hall sensor 13 captures the change in the drawer's position in real time and transmits the signal to the circuit program. After receiving the signal, the circuit program reverses the current direction of electromagnet 10 and electromagnet 21 again, so that the electromagnets generate an attractive force on magnet 17 and magnet 28. This attractive force is superimposed with the magnetic force of magnet 17 and magnet 28 themselves to form a resultant force, which tightly closes the drawer door, ensuring that the drawer is in a locked state and preventing accidental opening.

[0026] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
