[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0026] See also Figure 1 and Figure 2, which is an on-board power board 10 of an embodiment of the present invention, the on-board power board 10 has a power control circuit 11, which is arranged on both sides of the on-board power board 10, and the power control circuit 11 includes a rectifier circuit 11a and a DC power supply circuit 11b; the on-board power board 10 includes a rectangular portion 100 and a trapezoidal portion 200 connected to each other, the rectifier circuit 11a is arranged away from the rectangular portion 100 in a partial structure of the trapezoidal portion 200, and the DC power supply circuit 11b is respectively arranged in the remaining part of the trapezoidal portion 200 and the rectangular portion 100; the input end of the rectifier circuit 11a is used to receive AC power, the input end of the DC power supply circuit 11b is electrically connected to the output end of the rectifier circuit 11a, and the output end of the DC power supply circuit 11b is used to receive the power supply end of the sound panel.

[0027] like Figure 2 As shown, in one embodiment, the trapezoidal portion 200 has a first concave area 210 and a second concave area 220. The first concave area 210 is arranged on one side of the trapezoidal portion 200, and the second concave area 220 is arranged on the other side of the trapezoidal portion 200, so that the two side edges of the trapezoidal portion 200 are not too abrupt, and it is convenient for fingers to clamp the vehicle power board 10, while also further reducing the overall area of ​​the vehicle power board 10. Furthermore, the first concave area 210 and the second concave area 220 are arranged relative to each other.

[0028] like Figure 2 As shown, in one embodiment, the first concave area 210 includes a first arc partition 211 and a first straight partition 212 connected to each other, the first arc partition 211 is connected to one side of the rectangular portion 100, and the first straight partition 212 is connected to the top of the trapezoidal portion 200; the second concave area 220 includes a second arc partition 221 and a second straight partition 222 connected to each other, the second arc partition 221 is connected to the other side of the rectangular portion 100, and the second straight partition 222 is connected to the top of the trapezoidal portion 200.

[0029] It can be understood that the first arcuate partition 211 is used to abut against a fixing post inside the car radio, ensuring full contact between the fixing post and the side of the first arcuate partition 211. The second arcuate partition 221 is used to abut against another fixing post inside the car radio, ensuring full contact between the other fixing post and the side of the second arcuate partition 221, thereby providing a preliminary fixation. Specifically, when the first arcuate partition 211 abuts against the fixing post inside the car radio, the second arcuate partition 221 abuts against another fixing post inside the car radio, and one side of the rectangular portion 100 abuts against the third fixing post, the vehicle power board 10 can be secured and prevented from shifting within the vehicle radio. The first and second linear partitions 212, 222 ensure the smoothness of the sides of the trapezoidal portion 200, reducing the overall size of the vehicle power board 10 while preventing the first and second linear partitions 212, 222 from being obtrusive.

[0030] In this embodiment, the vehicle power board 10 has a rectangular portion 100 and a trapezoidal portion 200. Compared with the existing rectangular vehicle power board, the setting of the trapezoidal portion 200, especially the first concave area 210 and the second concave area 220, makes the overall area of ​​the vehicle power board 10 of this solution smaller. Therefore, when the vehicle power board 10 is installed inside the car radio, the vehicle power board 10 of this solution occupies a smaller area to adapt to more types of car radios, and thus the vehicle power board 10 is applicable to a wider range of vehicle models.

[0031] Combine Figure 1 and Figure 2 As shown, in one embodiment, the input terminals L / N of the rectifier circuit 11a are arranged at the top of the trapezoidal portion 200, and the output terminals V+ / V- of the DC power supply circuit 11b are arranged at the bottom of the rectangular portion 100. This arrangement allows AC power to be input from one side of the vehicle power board 10, and after being rectified into DC power, the DC power is output from the other side of the vehicle power board 10 to power the radio panel. This prevents the rectifier circuit 11a and the DC power supply circuit 11b from interfering with each other during operation of the vehicle power board 10, thereby ensuring the normal operation of the vehicle power board 10 and further ensuring the normal operation of the vehicle radio.

[0032] In one embodiment, the distance between the first concave area 210 and the second concave area 220 gradually decreases in a direction away from the rectangular portion 100 .

[0033] In one embodiment, the first linear partition 212 forms a certain angle with the horizontal line of the trapezoidal portion 200 , that is, the first linear partition 212 is tilted relative to the horizontal plane.

[0034] In one embodiment, the second linear partition 222 forms a certain angle with the horizontal line of the trapezoidal portion 200 , that is, the second linear partition 222 is tilted relative to the horizontal plane.

[0035] In one embodiment, the length of the vehicle-mounted power board 10 ranges from 27 mm to 30 mm. In this embodiment, the length of the vehicle-mounted power board 10 is 30 mm.

[0036] In one embodiment, the width of the vehicle power board 10 is in the range of 21 mm to 24 mm. In this embodiment, the width of the vehicle power board 10 is 22 mm.

[0037] like Figure 1 As shown, in one embodiment, the rectifier circuit 11a includes a first fuse resistor F1, a second fuse resistor F2, and a rectifier BD1. One rectifier input terminal of rectifier BD1 is connected to the live line of AC power via the first fuse resistor F1, while the other rectifier input terminals of rectifier BD1 are connected to the neutral line of AC power via the second fuse resistor F2. The rectifier output terminal of rectifier BD1 is electrically connected to the input terminal of the DC power supply circuit 11b. It will be understood that rectifier BD1 is used to rectify AC power into DC power. In the event of excessive current, the first fuse resistor F1 and / or the second fuse resistor F2 will fuse, protecting the circuit from excessive current breakdown and thus preventing the radio circuit board from overheating and burning through.

[0038] like Figure 1 As shown, in one embodiment, the rectifier circuit 11a further includes a filter capacitor C1. A first terminal of the filter capacitor C1 is connected to one input terminal of the rectifier BD1, and a second terminal of the filter capacitor C1 is connected to two input terminals of the rectifier BD1. It will be understood that when the rectifier BD1 rectifies AC power into DC power, the filter capacitor C1 is used to filter out interference signals present in the AC power, prevent fluctuations in the input AC power, and ensure stable DC power output after rectification by the filter.

[0039] The present disclosure also provides an in-vehicle power supply, comprising the in-vehicle power supply board 10 of any one of the above embodiments.

[0040] Compared with the prior art, the present disclosure has at least the following advantages:

[0041] The above-mentioned vehicle power board 10 has a rectangular portion 100 and a trapezoidal portion 200. Compared with the existing rectangular vehicle power board, the setting of the trapezoidal portion 200, especially the first concave area 210 and the second concave area 220, makes the overall area of ​​the vehicle power board 10 of this solution smaller. Therefore, when the vehicle power board 10 is installed inside the car radio, the vehicle power board 10 of this solution occupies a smaller area, so as to adapt to more types of car radios, and thus the vehicle power board 10 is applicable to a wider range of vehicle models.

[0042] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
