[0002] With the widespread adoption and diversification of electronic devices, magnetic stands, as a convenient tool for fixing and supporting equipment, have been widely used in daily life and industrial production. Traditional magnetic stands mainly rely on the principle of magnetism, using the attraction between magnets to firmly fix the device in a specific position. Their design focuses on the strength and stability of the magnetic force to meet the fixing needs in different scenarios. However, the functionality of existing magnetic stands is relatively simple, mainly limited to providing magnetic fixing functions, lacking additional added value or innovative features.

[0003] Most existing magnetic stands only offer magnetic attachment and cannot provide additional visual display or interactive experience. In today's pursuit of personalization and multifunctionality, this single function is no longer sufficient to meet the diverse needs of users. Due to design limitations, existing magnetic stands are often quite ordinary in appearance, lacking unique visual elements or design sense, making it difficult to attract users' attention or enhance the overall quality of the product.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-7 As shown, this utility model provides a magnetic base with a backlight structure. The entire structure consists of a shell 1, which comprises a top cover 101, a bottom plate 102, and a frame 103 connecting the two. During assembly, to improve the firmness and stability of the connection, the top cover 101 and the bottom plate 102 are each provided with a protruding mounting portion 104 that is embedded into the inner wall of the frame 103 for fixation. This magnetic base has a unique backlight structure, enabling the translucent display of specific patterns, and also possesses a magnetic attraction function, facilitating connection with other magnetic objects.

[0031] The bottom of the top cover 101 is provided with a light-shielding layer 2, which is made of opaque material and its function is to block light from being scattered in unintended directions. A patterned section 3 for light transmission is perforated in the center of the light-shielding layer 2. The shape of the patterned section 3 can be designed according to actual needs, such as a company logo or text. When the light projected by the LED light 6 is guided to the patterned section 3 through the light guide plate 4, the light will pass through the patterned section 3, forming a specific pattern display effect.

[0032] Inside the housing 1, from top to bottom, are arranged a light guide plate 4 and a PCB board 5. LEDs 6 are mounted on the PCB board 5, and the light projected by the LEDs 6 is guided to the pattern section 3 through the light guide plate 4. The PCB board 5 also has a PCB interface 7. One end of the PCB interface 7 is electrically connected to the PCB board 5, providing power and data signals to the electronic components such as the LEDs 6 on the PCB board 5. The other end of the PCB interface 7 is connected to a USB cable 9 extending outwards from the housing 1. The magnetic base can be connected to an external power supply or data device via the USB cable 9 to achieve power supply and data transmission. The USB cable 9 passes around the bottom of the PCB board 5 before connecting to the PCB interface 7. There are two PCB interfaces 7, one as a spare in case the other is damaged.

[0033] The bottom of the top cover 101 has two downward-extending fixing strips 106, and the opposite sides of the two fixing strips 106 have mounting grooves 107 for mounting the light guide plate 4. The light guide plate 4 is installed between the two fixing strips 106 and covers the patterned part 3. The two ends of the light guide plate 4 are respectively positioned in the corresponding mounting grooves 107 and fixed by the first locking member 12. The first locking member 12 can be a common fastener such as a screw. By tightening the first locking member 12, the light guide plate 4 is firmly fixed between the fixing strips 106, ensuring that the light guide plate 4 will not loosen during operation.

[0034] The top of the base plate 102 is provided with several protrusions 105 that provide suspended support and fix the PCB board 5. The protrusions 105 are into which second locking members 15 are inserted to lock the PCB board 5. The second locking member 15 can be a fastener such as a screw. By tightening the second locking member 15, the PCB board 5 is firmly fixed on the protrusions 105, so that the PCB board 5 maintains a stable position within the housing 1.

[0035] The bottom of the top cover 101 has two downwardly extending extensions 108, and two magnet mounting positions 8 are formed in different extensions 108. A first magnet 10 and a second magnet 11 are respectively installed in each magnet mounting position 8, and the polarities of the first magnet 10 and the second magnet 11 are opposite. This arrangement of magnets with opposite polarities allows the magnetic base to achieve a stable magnetic connection with other magnetic objects, and the direction and force of the magnetic attraction can be adjusted as needed.

[0036] Each of the two extensions 108 has a fixing part 109 on its opposite side for fixing the PCB interface 7. The fixing part 109 can be a groove or protrusion structure with a certain shape and size, used to stably fix the PCB interface 7 to the upper cover 101. At the same time, the upper cover 101 has several heat dissipation holes 110 aligned with the PCB interface 7. The function of the heat dissipation holes 110 is to promote air circulation around the PCB interface 7, dissipate the heat generated by the PCB interface 7 during operation in a timely manner, and ensure the normal operating temperature of the PCB interface 7.

[0037] Two counterweights 13 are symmetrically arranged on the top of the base plate 102. The function of the counterweights 13 is to increase the overall weight of the magnetic base and improve its stability. The base plate 102 is provided with several positioning seats 111 that pass through the middle of the counterweights 13, and the top cover 101 is provided with several positioning rods 112 that are inserted into the corresponding positioning seats 111 to fix the counterweights 13. During installation, the counterweights 13 are placed on the base plate 102, so that the positioning seats 111 pass through the middle of the counterweights 13, and then the positioning rods 112 of the top cover 101 are inserted into the positioning seats 111, thereby fixing the counterweights 13 between the base plate 102 and the top cover 101.

[0038] Two anti-slip pads 14 are symmetrically arranged on the bottom of the base plate 102. The anti-slip pads 14 are made of rubber or other materials with anti-slip properties. The anti-slip pads 14 are installed and fixed by a pre-set groove 113 on the bottom of the base plate 102. The shape and size of the groove 113 match the anti-slip pad 14. By embedding the anti-slip pad 14 into the groove 113, the anti-slip pad 14 can be fixedly installed. The function of the anti-slip pads 14 is to increase the friction between the magnetic base and the placement surface, preventing the magnetic base from sliding during use.

[0039] When the PCB board 5 is powered via the USB cable 9, the LEDs 6 on the PCB board 5 illuminate, and the light projected by the LEDs 6 enters the light guide plate 4. The light guide plate 4 guides the light evenly to the pattern section 3. Due to the blocking effect of the light-shielding layer 2, only the corresponding position of the pattern section 3 can transmit light, thereby forming a specific pattern display effect. At the same time, since the first magnet 10 and the second magnet 11 have opposite polarities, the magnetic base can be magnetically connected to other magnetic objects, making it easy to fix the magnetic base in the desired position.

[0040] Compared to traditional technologies, the magnetic base provided by this technical solution, through its unique backlight structure design, enables the translucent display of specific patterns on the pattern section 3, resulting in excellent visual effects. Simultaneously, the magnetic function increases the flexibility and convenience of the magnetic base, allowing for easy connection with other magnetic objects and enhancing usability.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
