Description

Technical Field

[0001] This invention relates to the field of distribution box technology, specifically a high-voltage distribution box that is easy to fix internal wiring. Background Technology

[0002] High-voltage battery junction boxes have many names, including high-voltage distribution boxes and high-voltage distribution units (PDUs). They generally include relays, current sensors, fuses, pre-charge resistors, etc. Simply put, the main function of a high-voltage junction box is to transfer or transmit the energy in the high-voltage battery to other high-voltage systems. The relays here can be regarded as high-current switches, which can cut off the current flowing through the bus and electrically isolate the high-voltage battery from other high-voltage components.

[0003] The high-voltage distribution box distributes the electrical energy delivered by the power battery pack to the motor controller, air conditioning compressor, and PTC heater. Additionally, during AC slow charging, the charging current also flows into the power battery through the distribution box to charge it. The distribution box contains fuses for the electric compressor circuit, PTC heater circuit, and AC slow charging circuit. When the current in these circuits exceeds 90A, the fuses will blow within 15 seconds; when the current exceeds 150A, the fuses will blow within 1 second, protecting the relevant circuits. The electrical principle of the distribution box is as follows: the DC charging interface can receive electrical energy from the DC charging pile and deliver it to the power battery pack through the high-voltage wiring harness to charge it.

[0004] After the electrical components are installed inside the high-voltage distribution box, the wiring inside the box often becomes quite messy, making it difficult for installers to organize and distinguish the wiring in different areas. Summary of the Invention

[0005] The purpose of this invention is to provide a high-voltage distribution box that is easy to fix internal wiring, so as to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] The present invention provides a high-voltage distribution box that is easy to fix internal wiring, including a box body, a wiring assembly fixedly installed inside the box body, a wire harness clip at the bottom of the wiring assembly, mounting beams on both sides of the wire harness clip, an isolation component at the end of the mounting beam away from the box body, and flip-up components extending through the box body on both sides of the box body, with electronic components mounted on the flip-up components.

[0008] Preferably, the wiring assembly includes a mounting plate fitted to the inner wall of the box, with a connecting tube at one end of the mounting plate away from the box, and a conductive block at the top of the connecting tube, the conductive block being arc-shaped in its entirety.

[0009] Preferably, the cable tie includes a torsion spring connected to the assembly beam, one end of the torsion spring is fixedly assembled to the assembly beam, and the other end of the torsion spring is equipped with a rotating rod, the outer wall of which is provided with a retaining plate.

[0010] Preferably, one end of the assembly beam is fixedly mounted to the inner wall of the box, and the other end of the assembly beam is provided with an arc-shaped limiting groove. The inner wall of the arc-shaped limiting groove matches the outer wall of the isolation component. There are three sets of assembly beams, and the arc-shaped limiting grooves are equidistantly distributed on each set of assembly beams. The arc-shaped limiting grooves on each set of assembly beams are staggered.

[0011] Preferably, the isolation assembly includes a top cover that engages with the top of the assembly beam, the bottom of the top cover having two sets of longitudinally arranged corrugated tubes, the two sets of corrugated tubes being rotatably connected by a rotating shaft, the outer wall of the corrugated tubes having a handle, the bottom of the corrugated tubes having a limiting disc, and the bottom of the limiting disc having a limiting component extending through to its top.

[0012] Preferably, the top of the limiting disk is provided with a limiting groove extending to its bottom. The limiting component includes a limiting block that matches the limiting groove. The bottom of the limiting block is provided with a first gear disk. The outer wall of the first gear disk meshes with a second gear disk. A rack is provided on one side of the second gear disk. A control rod is provided at the top of the rack.

[0013] Preferably, the bottom of the inner wall of the box body is provided with a cavity that matches the limiting component. The cavity is provided with a clearance groove for the rack to move. The top of the clearance groove is provided with a sliding groove that extends through to the bottom of the inner wall of the box body. The inner wall of the sliding groove matches the outer wall of the control rod.

[0014] Preferably, the flipping assembly includes an electric push rod mounted on the outer wall of the box. The output end of the electric push rod is connected to a movable slider. The movable slider has connecting rods extending to both ends inside. One end of the connecting rod is equipped with a third gear disk. The outer wall of the third gear disk is engaged with a fourth gear disk through a snap-fit ​​mechanism. A flipping arm is provided on one side of the fourth gear disk.

Electronic components are mounted on the front of the flipping plate. A guide arm is provided at the top of the connecting rod.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0016] This invention utilizes a cable management clip to facilitate the securing of wiring. When the operator pulls the clip, it rotates around a rotating rod, causing the rod to rotate as well. This rotation of the rod forces a torsion spring. Once the clip has rotated 45 degrees outward, the operator can place the wiring into the clip. Releasing the clip allows it to reset under the combined action of the torsion spring and the rotating rod, thus securing the wiring and preventing it from becoming loose. Simultaneously, an isolation component separates the wiring from electronic components, reducing temperature interference between the two. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of the present invention will now be described.

[0032] like Figures 1 to 7 As shown, a high-voltage distribution box that is easy to fix internal wiring includes a box body 100. A wiring assembly 200 is fixedly installed inside the box body 100. A wire harness clip 300 is provided at the bottom of the wiring assembly 200. A mounting beam 400 is provided on both sides of the wire harness clip 300. An isolation assembly 500 is provided at the end of the mounting beam 400 away from the box body 100. A flip assembly 600 is provided on both sides of the box body 100 and extends into the interior of the box body 100. Electronic components 700 are mounted on the flip assembly 600.

[0033] The isolation component 500 is used to isolate and separate the circuit from the electronic component 700 in order to reduce temperature interference between the circuit and the electronic component 700.

[0034] The flip assembly 600 is used to drive the electronic component 700 to perform a flipping motion;

[0035] The above structure facilitates the installation of wiring inside the high-voltage distribution box by opening the protective door and conveying the wiring from the bottom of the box 100 into the box 100. After the wiring is conveyed into the box, the staff first opens the isolation component 500, moves the wiring through the isolation component 500 to the assembly beam 400, and then opens the wire harness 300 to limit and constrain the wiring.

[0036] Please refer to section 2 and... Figure 3 The cable tie 300 includes a torsion spring connected to the assembly beam 400. One end of the torsion spring is fixedly assembled to the assembly beam 400, and the other end of the torsion spring is equipped with a rotating rod. The outer wall of the rotating rod is provided with a retaining plate.

[0037] The staff pulls the clamp plate, which rotates around the rotating rod, causing the rotating rod to rotate as well. The rotation of the rotating rod causes the torsion spring to be stressed. When the clamp plate rotates outward by 45 degrees, the staff can put the wire into the cable tie 300. Then, the limiting force on the clamp plate is released, and the clamp plate returns to its original position under the action of the torsion spring and the rotating rod, while fixing and limiting the wire to prevent the wire from becoming loose.

[0038] The wire tip clip, which is limited by the wire harness clip 300, is inserted into the wiring assembly 200 so that the wire supplies power to the wiring assembly.

[0039] Please refer to this carefully. Figure 2 The wiring assembly 200 includes a mounting plate mounted on the inner wall of the housing 100. The end of the mounting plate away from the housing 100 is provided with a connecting tube, and the top of the connecting tube is provided with a conductive block. The conductive block is arc-shaped in general.

[0040] The output end of the line is inserted into the connecting tube. Since there is a conductive card inside the connecting tube, and the other end of the conductive card is connected to the conductive block, the line is electrically connected to the conductive block.

[0041] After completing the electrical connection, the staff reset the isolation component 500;

[0042] Please refer to this carefully. Figure 2 , Figure 3 and Figure 5 As shown, one end of the assembly beam 400 is fixedly mounted to the inner wall of the box 100, and the other end of the assembly beam 400 is provided with an arc-shaped limiting groove. The inner wall of the arc-shaped limiting groove matches the outer wall of the isolation component 500. There are three sets of assembly beams 400, and the arc-shaped limiting grooves are distributed in an equidistant array on each set of assembly beams 400. The arc-shaped limiting grooves on each set of assembly beams 400 are staggered.

[0043] Please refer to this carefully. Figure 5 The isolation assembly 500 includes a top cover 510 that engages with the top of the assembly beam 400. The bottom end of the top cover 510 is provided with two sets of longitudinally arranged corrugated tubes 520. The two sets of corrugated tubes 520 are rotatably connected by a rotating shaft 530. The outer wall of the corrugated tube 520 is provided with a handle 540. The bottom end of the corrugated tube 520 is provided with a limiting plate 550. The bottom end of the limiting plate 550 is provided with a limiting component 560 that extends through to its top end.

[0044] After the staff opens the limiting component 560, they can pull the bellows 520 to make a telescopic movement by holding the handle 540. At the same time, the setting of the rotating shaft 530 allows the two sets of bellows 520 to rotate, so that the staff can put the line into the isolation component 500.

[0045] Please refer to this carefully. Figure 6 and Figure 7The top of the limiting disk 550 is provided with a limiting groove extending to its bottom. The limiting component 560 includes a limiting block 561 that matches the limiting groove. The bottom of the limiting block 561 is provided with a first gear disk 562. The outer wall of the first gear disk 562 is meshed with a second gear disk 563. A rack 564 is provided on one side of the second gear disk 563. A control rod 565 is provided at the top of the rack 564.

[0046] The operator moves the control lever 565, which in turn moves the rack 564. The rack 564 then rotates the second gear disk 563, which in turn rotates the first gear disk 562. The first gear disk 562 then rotates the limit block 561. When the limit block 561 rotates to coincide with the limit groove, the limit component 560 releases its restriction on the limit disk 550.

[0047] The bottom of the inner wall of the box 100 is provided with a cavity that matches the limiting component 560. Inside the cavity, there is a clearance groove for the rack 564 to move. The top of the clearance groove is provided with a sliding groove that extends to the bottom of the inner wall of the box 100. The inner wall of the sliding groove matches the outer wall of the control rod 565.

[0048] The length of the clearance groove allows the rack 564 to move just enough for the second gear disk 563 to rotate forty-five degrees.

[0049] Please refer to this carefully. Figure 1 and Figure 4 As shown, the flipping assembly 600 includes an electric push rod 610 mounted on the outer wall of the box 100. The output end of the electric push rod 610 is connected to a movable slider 620. The movable slider 620 has connecting rods 630 extending to both ends inside. One end of the connecting rod 630 is equipped with a third gear disk 640. The outer wall of the third gear disk 640 is engaged with a fourth gear disk 650 through a snap-tooth mechanism.

[0050] A flipping arm 660 is provided on one side of the fourth gear disk 650, and the other side of the fourth gear disk 650 is rotatably connected to the movable slider 620 via a rotating shaft. A flipping plate 670 is provided at one end of the flipping arm 660. A connecting block 680 matching the wiring assembly 200 is mounted on the back of the flipping plate 670. An electronic component 700 is mounted on the front of the flipping plate 670. A guide arm 690 is provided at the top of the connecting rod 630. The guide arm 690 and the connecting rod 630 are rotatably connected via a rotating shaft.

[0051] The above structure facilitates the operation of the electric push rod 610. When the electric push rod 610 is activated, the output end of the electric push rod 610 drives the movable slider 620 to move, and the movable slider 620 drives the connecting rod 630 to move. Since the connecting rod 630 and the guide arm 690 are rotatably connected by a rotating shaft, the connecting rod 630 moves in a fan-shaped motion. The fan-shaped motion of the connecting rod 630 drives the third gear disk 640 to rotate, which in turn drives the fourth gear disk 650 to rotate. The rotation of the fourth gear disk 650 drives the flipping arm 660 to move in a fan-shaped motion, and the fan-shaped motion of the flipping arm 660 drives the flipping plate 670 to move in a fan-shaped motion. The fan-shaped motion of the flipping plate 670 drives the electronic component 700 to move in a fan-shaped motion.

[0052] The staff uses the flipping component 600 to move the electronic component 700 upwards while flipping it, revealing the circuitry on the back of the electronic component 700 and making room for the staff to quickly and easily install or repair the circuitry.
