These power distribution modules are vehicle-specific electrical devices such as distribution boxes or cabinets. Currently, similar products on the market have two drawbacks: First, current power distribution modules have a limited number of input and output channels, requiring multiple modules to distribute power to all low-voltage equipment in the vehicle. Second, previous power distribution modules did not consider the neatness and aesthetics of wiring harness installation, resulting in the problem of wires being pulled and stretched. Utility Model Content

Detailed Implementation
[0026] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0027] In one embodiment, a global digital power distribution module is provided, such as Figure 1-2 As shown, the global digital power distribution module includes an upper shell 10, in which a circuit board 20 is provided. The circuit board 20 is fixedly installed in the upper shell 10. The circuit board 20 is provided with components for performing global digital power distribution to the vehicle. For example, the circuit board 20 is provided with a main control unit, a communication unit, an electronic switch array, an electronic switch drive circuit, etc. Here, the electronic switch array refers to a transistor array composed of transistors, IGBTs (insulated gate bipolar transistors), MOSFETs, etc., which can be controlled by signals.
[0028] A rear cover 30 is provided at the bottom of the upper shell 10, and a sealing ring 31 is provided between the upper shell 10 and the rear cover 30, so that an IP67 level sealing protection is formed between the upper shell 10 and the rear cover 30.
[0029] Multiple sockets 11 are provided on the outside of the upper shell 10. The sockets 11 are D-type interfaces and are integrally formed with the upper shell 10. Each socket 11 is provided with a conductive pin 12 that is electrically connected to the circuit board 20. Multiple conductive pins 12 can be provided in each socket 11. Each conductive pin 12 can be used as an output or input terminal. The conductive pins 12 are mainly suitable for power distribution to low-voltage equipment with lower power in the vehicle, such as turn signals, various sensors, displays, dashcams, car chargers, etc.
[0030] The top of the upper housing 10 is also provided with multiple conductive bolts 40 that are electrically connected to the circuit board 20. The conductive bolts 40 are suitable for distributing power to low-voltage equipment with higher power in the vehicle, such as the steering gear, air conditioning compressor, and ventilation heater. The circuit board 20 needs to be equipped with electronic switches that support the corresponding power. For example, by setting IGBTs on the circuit board 20, the high power conductivity requirements of the conductive bolts 40 can be met.
[0031] The global digital power distribution module operates as follows: A signal is sent from the vehicle's control center to circuit board 20. Upon receiving the signal, the communication unit on circuit board 20 controls the corresponding electronic switch to turn on or off via the main control unit, thereby controlling the power supply to the corresponding low-voltage equipment. For example, regarding the control of the vehicle's turn signals, when the turn signal lever is moved, the vehicle's control center receives a signal and sends a turn signal to circuit board 20. Upon receiving this signal, the communication unit on circuit board 20 controls the electronic switch of the turn signal to turn on via the main control unit, thus activating the turn signal.
[0032] This is just one example of how it works. For instance, if the control center on the vehicle has an electronic switch drive circuit, the electronic switch array on the circuit board 20 can be controlled directly by the control center. In this case, there is no need to set up components or functional circuits such as the main control unit, communication unit, and electronic switch drive circuit on the circuit board 20.
[0033] The global digital power distribution module has the following advantages: Since there are multiple sockets 11, a sufficient number of conductive pins 12 can be provided. These conductive pins 12 can distribute power to low-power, low-voltage equipment on the vehicle. In addition, multiple conductive bolts 40 that can distribute power to high-power, low-voltage equipment are provided, forming a power distribution scheme that combines high and low power. Through this one power distribution module, the entire vehicle can be powered, improving the centralization of power distribution.
[0034] The term "global digital power distribution" here refers to the ability of a single power distribution module to distribute power to all low-voltage equipment in the entire vehicle. Furthermore, because the conductive pins can input or output communication or control signals, digital power distribution can be achieved.
[0035] Furthermore, in another embodiment, such as Figure 2 As shown, the global digital power distribution module has a socket arrangement area 13 on the top surface of the upper shell 10, with sockets 11 arranged in the socket arrangement area 13. The socket arrangement area 13 occupies most of the top surface of the upper shell 10. On the side of the top surface of the upper shell 10, there is a bolt arrangement area 14 that is lower than the socket arrangement area 13, with bolts 40 arranged in a row in the bolt arrangement area 14. By setting up the socket arrangement area 13 and the bolt arrangement area 14, the sockets 11 and bolts 40 on the top surface of the upper shell 10 can be centrally arranged in their respective areas, which facilitates wiring during use.
[0036] Furthermore, in another embodiment, such as Figure 1-2 As shown, the global digital power distribution module has a wire harness binding bracket 50 located next to the socket 11 on the outside of the upper shell 10. The wire harness binding bracket 50 is used to bind the wire harness connected to the global digital power distribution module, so that the wire harness is neater.
[0037] like Figure 2-3 As shown, the wire harness binding bracket 50 includes a bracket base 51 and an L-shaped bracket rod 52. A connecting structure is provided between the bracket base 51 and the corresponding socket 11. The connecting structure includes an mounting protrusion 111 on the outside of the socket 11 and a mounting groove 511 on the side of the bracket base 51. One wire harness binding bracket 50 is positioned between two adjacent sockets 11. Mounting grooves 511 are provided on both sides of the bracket base 51, and mounting grooves 511 are also provided on the corresponding sides of the two sockets 11 adjacent to the bracket base 51. The two connecting structures provide a more stable installation of the wire harness binding bracket 50. By designing a dedicated wire harness binding bracket 50, wire harnesses can be bound to the bracket, allowing the external wiring harnesses of the socket 11 to be neatly led out. Furthermore, the wire harness binding bracket 50 is connected to the outside of the socket 11 via a snap-fit structure in the form of a groove and protrusion, facilitating easy installation and disassembly.
[0038] Furthermore, in another embodiment, such as Figure 4 As shown, the global digital power distribution module has a partition protrusion 15 between adjacent conductive bolts 40 in the bolt arrangement area 14. By setting the partition protrusion 15, the wires connected on adjacent conductive bolts 40 can be separated, making the wiring neater and clearer.
[0039] Furthermore, in another embodiment, such as Figure 1-2 As shown, the global digital power distribution module has a hinged cover 60 at the top of the upper shell 10, and each conductive bolt 40 is covered in the cover 60. Figure 5 As shown, the side of the flip cover 60 is hinged to the side of the upper shell 10 via a hinge lug, allowing the flip cover 60 to flip up and down. A protective plate 61 is provided on the flip cover 60, which is integrally set on the front side of the flip cover 60. The protective plate 61 has multiple wire through holes 611, so that each conductive bolt 40 has a corresponding wire through hole 611. The protective plate 61 is made of flexible insulating material such as rubber. Dustproof sheets 612 on the left and right sides are provided in each wire through hole 611. The dustproof sheets 612 are flexible and can be opened to allow wires to be threaded through.
[0040] Furthermore, in another embodiment, such as Figure 4 As shown, each conductive bolt 40 of the global digital power distribution module is provided with a corresponding wire clamping nut 41. When wiring, the copper lug of the wire is passed through the conductive bolt 40, and then the wire clamping nut 41 is tightened to press the copper lug.
[0041] like Figure 1 As shown, the wire through-hole 611 faces the front side of the upper shell 10, and the openings of each socket 11 face the top of the upper shell 10. In this way, the wires connected to the conductive bolt 40 are led out from the front side of the upper shell 10, and the wires connected to each socket 11 are led out from the top of the upper shell 10, which facilitates wiring.
[0042] Furthermore, in another embodiment, such as Figure 2 As shown, the back cover 30 of the global digital power distribution module is made of aluminum plate. An X-shaped strip protrusion 32 is provided on the back cover 30. The strip protrusion 32 contacts the non-conductive area on the bottom surface of the circuit board 20 so as to allow the circuit board 20 to dissipate heat.
[0043] Furthermore, in another embodiment, such as Figure 2 and Figure 5 As shown, this global digital power distribution module has 15 sockets 11, each with 15 conductive pins 12, for a total of 225 conductive pins 12; and 16 conductive bolts 40. By providing 225 low-power input / output conductive pins 12 and adding 16 high-power conductive bolts 40, it is currently the power distribution module with the most input / output channels on the market, capable of meeting the power distribution needs of various low-voltage devices in the vehicle.
