[0028] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] like Figures 1 to 6 The diagram illustrates an embodiment of this utility model, relating to an on-board stable diode, comprising a diode body 10. The diode body 10 includes a housing 20, an upper junction box 30, and a lower junction box 40. The lower part of the housing 20 is connected to the upper junction box 30, and a plurality of insert blocks 21 are fixedly connected to the bottom of the housing 20. The lower part of the upper junction box 30 is elastically connected to the lower junction box 40, and the upper part of the upper junction box 30 is provided with an insertion hole 31, which is matched and connected to the insert blocks 21. The lower junction box 40 has an internal mounting cavity 41, and the bottom of the mounting cavity 41 is provided with a plurality of first elastic members 50 and a plurality of second elastic members 60. The tops of the first elastic members 50 and the second elastic members 60 are connected to a transition plate 32, which is fixedly connected to the bottom of the upper junction box 30 and is limited and snapped into the lower junction box 40. The second elastic members 60 are located between two adjacent first elastic members 50.
[0030] Furthermore, the upper junction box 30 and the lower junction box 40 are elastically connected. The first elastic element 50 and the second elastic element 60 inside the lower junction box 40 are connected to the transition plate 32, which is then fixed to the bottom of the upper junction box 30. This design can efficiently absorb vibration energy when the vehicle encounters bumps and swaying during operation. When the vehicle frequently passes over speed bumps or rough mountain roads, the elastic elements can significantly reduce the vibration transmitted to the diode body 10, effectively preventing the diode from loosening and falling off due to vibration, and ensuring stable connection and operation even under complex road conditions.
[0031] Furthermore, the second elastic element 60 is cleverly positioned between two adjacent first elastic elements 50, constructing a comprehensive elastic buffer system that enables the diode to have excellent vibration resistance in all directions, further ensuring its stability and connection reliability in vibration environments.
[0032] Furthermore, the bottom of the housing 20 is provided with a plurality of first connecting blocks 22, and the top of the upper junction box 30 is provided with a plurality of second connecting blocks 33, the second connecting blocks 33 being magnetically connected to the first connecting blocks 22. Specifically, the first connecting blocks 22 at the bottom of the housing 20 and the second connecting blocks 33 at the top of the upper junction box 30 are magnetically connected, which greatly simplifies the assembly process of each part of the diode body 10; in the production process, it can significantly improve production efficiency and reduce assembly costs; and in daily vehicle use, the magnetic connection can effectively resist factors such as vibration, prevent the housing 20 and the upper junction box 30 from separating accidentally, and enhance the overall structural stability; at the same time, the magnetic connection between the second connecting blocks 33 and the first connecting blocks 22 constitutes a suspended connection between the diode body 10 and the upper junction box 30, thus not affecting the heat dissipation requirements of the diode body 10.
[0033] like Figure 5 As shown, in some embodiments, the first connecting block 22 at the bottom of the housing 20 and the second connecting block 33 at the top of the upper junction box 30 are not only magnetically connected, but also have matching snap-fit structures 11 on the sides of the connecting blocks. The snap-fit structure 11 consists of a protrusion and a groove. When the first connecting block 22 and the second connecting block 33 are magnetically attached, the protrusion can be inserted into the groove to form a double fixation.
[0034] Further, the first elastic element 50 includes a support rod 51, a sleeve 52, and a first spring 53; the support rod 51 is movably connected to the sleeve 52; the sleeve 52 is fixed to the inner bottom of the mounting cavity 41; the first spring 53 is located inside the sleeve 52 and is connected to the bottom of the support rod 51; the top of the support rod 51 is connected to the lower part of the transition plate 32, and the bottom of the support rod 51 is connected to a first connecting plate 54, which is connected to the top of the first spring 53. Specifically, the support rod 51 can move flexibly within the sleeve 52, and the first spring 53 is responsible for providing buffering force. When the vehicle vibrates, this structure can quickly convert the vibration energy into the elastic potential energy of the spring, resulting in a significant buffering effect, effectively reducing the impact of vibration on the diode and lowering the risk of loosening.
[0035] Further, the second elastic element 60 includes an upper hinge seat 61, a lower hinge seat 62, a first double-headed hinge block 63, and a second double-headed hinge block 64; the upper hinge seat 61 is fixed below the transition plate 32, and two ends of the upper hinge seat 61 are respectively hinged to first connecting rods 65, and the two first connecting rods 65 are respectively hinged to the upper parts of the first double-headed hinge block 63 and the second double-headed hinge block 64; the lower hinge seat 62 is fixed to the inner bottom of the mounting cavity 41, and two ends of the lower hinge seat 62 are respectively hinged to second connecting rods 66, and the two second connecting rods 66 are respectively hinged to the lower parts of the first double-headed hinge block 63 and the second double-headed hinge block 64; the second elastic element 60 also includes a tension spring 67, and the two ends of the tension spring 67 are respectively connected to the first double-headed hinge block 63 and the second double-headed hinge block 64. Specifically, the second elastic element 60 works in concert with the upper hinge seat 61, the lower hinge seat 62, the first double-headed hinge block 63, the second double-headed hinge block 64, and the tension spring 67. When subjected to vibration, each hinge component can rotate flexibly, and the tension spring 67 further enhances the buffering and shock absorption effect, ensuring the stability of the diode in the vibration environment from multiple dimensions and ensuring that its connection is not affected.
[0036] In some embodiments, a memory foam layer is filled between the upper junction box 30 and the lower junction box 40. This material has excellent elastic recovery and cushioning performance, and can effectively absorb vibration energy during vehicle operation.
[0037] Furthermore, limiting holes 34 are respectively provided on both sides of the insertion hole 31. A third elastic element 70 is provided inside the limiting hole 34, and the third elastic element 70 is movably connected to the insertion block 21. The third elastic element 70 includes a hemispherical dome 71 and a second spring 72. A second connecting plate 73 is provided at the end of the hemispherical dome 71 facing away from the insertion block 21. The second spring 72 is connected to one end of the second connecting plate 73, and the end of the second spring 72 facing away from the second connecting plate 73 is connected to the inside of the limiting block. Specifically, the hemispherical dome 71 and the second spring 72 are movably connected to the insertion block 21. This design, on the one hand, provides precise positioning of the insertion block 21, ensuring that the insertion block 21 is securely inserted into the insertion hole 31 and maintaining a stable connection during normal vehicle operation; on the other hand, when the vehicle bumps or shakes or encounters external force, the third elastic element 70 can adapt to the slight displacement of the insertion block 21 through its own elastic deformation, effectively preventing the insertion block 21 from loosening and falling off, ensuring the reliability of the connection.
[0038] Furthermore, the diode body 10 also includes a plurality of first pins 12 and a plurality of second pins 13, the first pins 12 and the second pins 13 being respectively connected to both sides of the housing 20. Specifically, the first pins 12 and the second pins 13 provided on the diode body 10 facilitate connection with external circuits.
[0039] Furthermore, a circuit board 14 is connected below the diode body 10, and the lower junction box 40 is interference-fitted above the circuit board 14. Specifically, the lower junction box 40 and the circuit board 14 are interference-fitted. This connection method is tight and reliable, ensuring that the electrical connection between the diode and the circuit board 14 remains stable during vehicle operation. This facilitates smooth current transmission, enabling the diode to operate stably in the vehicle power system and providing reliable support for vehicle electronic devices. In some embodiments, the lower junction box 40 is directly soldered onto the circuit board 14 using surface mount technology (SMT) to ensure the stability of the electrical connection. Simultaneously, several elastic support feet 16 are provided on the edge of the circuit board 14. These support feet are made of elastic metal material, with one end fixed to the circuit board 14 and the other end connected to the mounting position inside the vehicle via screws or other means. The elastic support feet 16 can play a role in shock absorption and buffering during vehicle operation, protecting the circuit board 14 and the diode from vibration, while also facilitating the installation and fixation of the diode inside the vehicle.
[0040] This utility model features a rational overall design, with comprehensive optimization at the structural design level. Through a series of innovative designs, including flexible connection, buffering and shock absorption, convenient assembly, connection limiting, and stable circuit connection, the stability and reliability of diodes in the complex automotive environment are significantly improved. It not only effectively solves existing technical problems but also provides strong support for the stable operation of automotive electronic devices, meeting the stringent requirements of intelligent vehicles for high stability and reliability of automotive electronic components. It possesses extremely high practical value and promising market application prospects.
[0041] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
