It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0032] Refer to the following Figures 1 to 14 A vehicle-mounted power distribution cabinet with a line protection function provided according to some embodiments of the present application is described.

[0033] like Figures 1 - 14As shown in the figure, the in-vehicle power distribution cabinet with line protection function provided by some embodiments of the present application includes a power distribution cabinet assembly 1, a mounting assembly 2, an induction fire extinguishing assembly 3, a connection assembly 4, a power-off assembly 5, and a positioning assembly 6. Among them, the power distribution cabinet assembly 1 includes a cabinet body 11, which serves as the main support structure; the mounting assembly 2 is rotatably connected to the power distribution cabinet assembly 1, and the mounting assembly 2 includes: a rotating disk 21, which is rotatably connected to the cabinet body 11 and is used to support the vehicle line equipment to rotate; the induction fire extinguishing assembly 3 is arranged in the cabinet body 11, and the induction fire extinguishing assembly 3 includes: a temperature sensor, which is used to sense the temperature in the cabinet body 11; a fire extinguisher bottle 33, which is equipped with dry powder fire extinguishing agent inside, and the sensor triggers a signal to drive the control valve 34 to open, and the fire extinguisher bottle 33 releases dry powder to extinguish the fire; the connection assembly 4 is connected to the induction fire extinguishing assembly 3; the power-off assembly 5 is arranged on the top of the cabinet body 11 and is connected to the connection assembly 4, and is used to separate the internal line joints of the cabinet body 11 to achieve power-off; the positioning assembly 6 is arranged at the bottom of the cabinet body 11 and is connected to the mounting assembly 2, and is used for positioning the mounting assembly 2.

[0034] It should be noted that the mounting assembly 2 is rotatably installed in the cabinet body 11 and can rotate flexibly, which is convenient for the installation and maintenance of the lines; the induction fire extinguishing assembly 3 includes a temperature sensor and a fire extinguisher bottle 33, which are used to monitor the temperature in the cabinet body 11 and trigger the opening of the fire extinguisher bottle 33 to complete the fire extinguishing; the connection assembly 4 serves as the connection structure between the induction fire extinguishing assembly 3 and the power-off assembly 5, and is responsible for transmitting the trigger signal and timely driving the power-off assembly 5 to perform power-off processing; the positioning assembly 6 positions the mounting assembly 2 and judges the rotation angle of the mounting assembly 2.

[0035] When the in-vehicle power distribution cabinet with line protection function is operating, the cabinet body 11 is installed in a suitable area of the vehicle, the mounting assembly 2 fixes the line equipment, the induction fire extinguishing assembly 3 senses the temperature in the cabinet body 11 in real time. When the temperature exceeds the preset threshold, the sensor triggers a signal to drive the fire extinguisher bottle 33 to release dry powder fire extinguishing agent to quickly extinguish the fire, and triggers the connection assembly 4, so that the power-off assembly 5 performs power-off processing on the line equipment in the cabinet body 11 to prevent the leakage danger caused by the current of the power line, and the positioning assembly 6 can judge the rotation angle of the mounting assembly 2.

[0036] In some possible embodiments, as Figures 1 - 3 shown, the power distribution cabinet assembly 1 includes: two cabinet doors 12, which are movably connected to the cabinet body 11; a plurality of sealing strips 13, which are arranged at the bottom and top of the cabinet body 11 and are in contact with the cabinet doors 12; a partition plate 14, which is arranged at the bottom of the cabinet body 11.

[0037] In this embodiment, the cabinet door 12 is pivotally connected to the cabinet body 11, enabling the cabinet door 12 to be easily opened and closed; the sealing strip 13 contacts the cabinet door 12 when it is closed, improving the overall sealing performance of the cabinet body 11 and effectively preventing external impurities such as dust and moisture from entering the cabinet body 11; the partition board 14 is arranged at the bottom of the cabinet body 11 to divide the internal space of the cabinet body 11, improving the space utilization rate of the power distribution cabinet.

[0038] In some possible embodiments, as Figures 4 - 6 shown, the mounting assembly 2 includes: a first mounting plate 22, rotatably connected to the cabinet body 11 and arranged at the top of the cabinet body 11; a vertical frame 23, arranged between the rotating disk 21 and the first mounting plate 22; and a plurality of horizontal frames 24, arranged on the vertical frame 23.

[0039] In this embodiment, the rotating disk 21 and the first mounting plate 22 are rotatably connected to the cabinet body 11 to ensure free rotation. The vertical frame 23 is vertically arranged between the rotating disk 21 and the first mounting plate 22, and the plurality of horizontal frames 24 are horizontally arranged on the vertical frame 23, forming multiple mounting levels. Users can install line equipment on the horizontal frames 24 at different heights, and the horizontal frames 24 and the vertical frame 23 can rotate according to the rotation of the rotating disk 21 and the first mounting plate 22, effectively utilizing the internal space of the cabinet body 11 in three-dimensional space and improving the installation flexibility and space utilization rate.

[0040] In some possible embodiments, as Figure 4 shown, the mounting assembly 2 further includes: a plurality of balls 25, movably connected to the bottom of the rotating disk 21; a support rail 26, arranged on the partition board 14, and the balls 25 are evenly distributed in the support rail 26.

[0041] In this embodiment, a plurality of balls 25 are arranged between the rotating disk 21 and the support rail 26. The balls 25 roll freely in the support rail 26, which can reduce the frictional resistance and improve the smoothness of rotation, thereby improving the convenience of installing line equipment. In some possible embodiments, as Figures 11 - 13 shown, the induction fire extinguishing assembly 3 includes: a fixed frame 31, fixedly arranged inside the cabinet body 11; a clamping frame 32, arranged on the fixed frame 31 for fixing the fire extinguisher 33; and a control valve 34, arranged at the bottom of the fire extinguisher 33, and the control valve 34 is used in cooperation with the temperature sensor.

[0042] In this embodiment, the fixed frame 31 is fixed to the inner top of the cabinet body 11. The clamping frame 32 is arranged inside the fixed frame 31 for fixing the fire extinguisher bottle 33. The fire extinguisher bottle 33 is filled with a fire extinguishing agent. A control valve 34 is arranged at the bottom of the fire extinguisher bottle 33 and is used in cooperation with the temperature sensor. When the temperature sensor detects that the temperature inside the cabinet body 11 exceeds the preset threshold, the control valve 34 is automatically triggered to open, so that the fire extinguishing agent is quickly released to extinguish the fire source, improving the safety of use of the power distribution cabinet.

[0043] In some possible embodiments, such as Figure 12 、 Figure 13 shown, the connection component 4 includes: a plurality of first support seats 41 fixedly arranged inside the cabinet body 11; a toggle rod 42 movably connected to the first support seats 41; an inclined port interface 43 connected to the control valve 34 and in contact with one end of the toggle rod 42; and a toggle block 44 arranged at the other end of the toggle rod 42.

[0044] In this embodiment, the first support seats 41 are fixedly arranged inside the cabinet body 11 to provide a support basis for the toggle rod 42, and the movable rod 42 can move inside the first support seats 41. The inclined port interface 43 and the toggle block 44 are arranged at both ends of the toggle rod 42. When the control valve 34 sprays out the fire extinguishing agent, due to the action of the inclined block of the inclined port interface 43, the toggle rod 42 is driven to push forward, and the force is transmitted to the toggle block 44.

[0045] In some possible embodiments, such as Figure 12 、 Figure 13 shown, the connection component 4 further includes: a connection frame 45 arranged inside the cabinet body 11; a second support seat 46 fixedly arranged inside the cabinet body 11; a rotating handle 47 rotatably connected to the second support seat 46 and in contact with the toggle block 44; and the connection frame 45 is movably connected to the rotating handle 47.

[0046] In this embodiment, the second support seat 46 is fixed to the inside of the cabinet body 11 as the rotation basis of the rotating handle 47. The rotating handle 47 is subjected to the thrust of the toggle block 44 and acts together with the power-off component 5, so that the rotating handle 47 can rotate 180 degrees around the second support seat 46, driving the connection frame 45 to move upward, thereby triggering the power-off component 5 to perform a power-off operation.

[0047] In some possible embodiments, such as Figures 7 - 10As shown in the figure, the power-off component 5 includes: two fixed blocks 51, symmetrically distributed and fixed inside the cabinet body 11; a first spring 52, arranged at the bottom of the fixed block 51; a second mounting plate 53, arranged at the bottom of the first spring 52, and the first spring 52 is arranged between the fixed block 51 and the second mounting plate 53; a plurality of first connectors 54, arranged on the first mounting plate 22; a plurality of second connectors 55, arranged on the second mounting plate 53, with the same number as the first connectors 54 and meshing with them.

[0048] In this embodiment, a plurality of first connectors 54 are arranged on the first mounting plate 22, and a plurality of second connectors 55 are arranged on the second mounting plate 53. The first spring 52 provides elastic support for the second mounting plate 53 in the upward vertical direction. That is, when the rotating handle 47 is pushed, the first spring 52 restores its elastic deformation, causing the second mounting plate 53 and the connecting frame 45 to move upward, so that the rotating handle 47 rotates 180 degrees. At the same time, the first connector 54 and the second connector 55 are separated, realizing the power-off operation to prevent electric leakage caused by the line current or a larger fire during a fire.

[0049] In some possible embodiments, as Figure 8 , Figure 10 shown, the power-off component 5 further includes: a limit frame 56, arranged on the first mounting plate 22; a positioning member 57, fixedly arranged at the bottom of the second mounting plate 53; and a groove meshing with the positioning member 57 is arranged inside the limit frame 56.

[0050] In this embodiment, a groove meshing with the positioning member 57 is arranged inside the limit frame 56. The function of the groove is to guide the path of the positioning member 57 during the reset process, ensuring that the second mounting plate 53 can accurately dock with the first mounting plate 22 and ensuring the accurate docking of the first connector 54 and the second connector 55 inside it.

[0051] In some possible embodiments, as Figure 14 shown, the positioning component 6 includes: a mounting frame 61, arranged at the bottom of the cabinet body 11; a positioning pin 62, arranged on the mounting frame 61, and a groove meshing with the positioning pin 62 is arranged on the outside of the rotating disc 21; a second spring 63, arranged on the positioning pin 62.

[0052] In this embodiment, the mounting frame 61 is fixed at the bottom of the cabinet body 11, providing a moving space for the positioning pin 62. On the outside of the rotating disc 21, a groove matching the shape and size of the positioning pin 62 is arranged. When the rotating disc 21 rotates to the horizontal and vertical position, the force of the second spring 63 inside the positioning pin 62 pushes the positioning pin 62 into the groove to limit the rotating disc 21. At this time, the position of the first connector 54 inside the first mounting plate 22 corresponds to the second connector 55, and the power-off component 5 can be reset.

[0053] When the vehicle-mounted power distribution cabinet with line protection function is in operation, the rotating disk 21 and the first mounting disk 22 are rotated to a suitable installation angle, and the ball 25 is used to roll freely in the support rail 26, so that the rotating disk 21 rotates smoothly. The user installs the line equipment in the cabinet 11, and uses the vertical frame 23 and the horizontal frame 24 to provide multiple installation levels. It is installed at different heights according to needs. The temperature sensor monitors the temperature in the cabinet 11 in real time. When the temperature exceeds the preset threshold, the sensor triggers a signal to drive the control valve 34 of the fire extinguisher bottle 33 to open, release the dry powder fire extinguishing agent to extinguish the flame, and at the same time, the bevel interface 4 is used when the dry powder is sprayed. 3 guides the dry powder to spray to the right, thereby pushing the driving rod 42, and the driving rod 42 moves in the first support seat 41, so that the toggle block 44 pushes the rotating handle 47 to release the lock of the connecting frame 45. At the same time, the first spring 52 is forced to restore elastic deformation, and the second mounting plate 53 moves up, so that the first joint 54 is separated from the second joint 55, and the power-off operation is realized. The function of the positioning pin 62 is to judge whether the rotating plate 21 is in a horizontal or vertical state. At this time, the first joint 54 and the second joint 55 in the second mounting plate 53 are in a corresponding state. When it is necessary to restore the power supply operation, the positioning pin 62 is inserted into the rotating plate 21.
