Description

Technical Field

[0001] The invention relates to the technical field of automobile high-voltage wire harness assembly, in particular to an automobile high-voltage wire harness fixing bracket group. Background Art

[0002] Electric vehicles include motor controllers, battery high-voltage cabinets, four-in-one controllers, power batteries, air ducts, and high-voltage wire harnesses arranged between them. In order to make the high-voltage wire harnesses in the vehicle reasonably and clearly arranged, the high-voltage wire harnesses need to be bundled and fixed. Specifically, the prior art uses cable ties to bundle the high-voltage wire harnesses at the high-voltage wire harness outlets of the motor controller, battery high-voltage cabinet, and four-in-one controller respectively; uses cable ties to bundle and fix the high-voltage wire harnesses coming out of the high-voltage wire harness plug-in end of the power battery with the wire harness fixing point on the power battery; uses insulating wire clamps to bundle the high-voltage wire harnesses in the air duct; and uses insulating wire clamps to bundle and fix the high-voltage wire harnesses between the motor controller, battery high-voltage cabinet, four-in-one controller, power battery, and air duct.

[0003] However, the high-voltage wire harness fixing method in the prior art has the following defects:

[0004] 1. A large number of insulating wire clamps are needed. First of all, each insulating wire clamp needs to be welded with a corresponding support frame when in use, which makes the fixing operation of the high-voltage wire harness very cumbersome and complicated; secondly, the insulating wire clamps need to be selected according to the diameter and number of high-voltage wires, and they cannot be universal. When a suitable insulating wire clamp cannot be matched, it needs to be further fixed with a cable tie, which further increases the difficulty of using the insulating wire clamps; finally, the insulating wire clamps cannot bind the high-voltage wire harness horizontally and vertically, making the routing of the high-voltage wire harness unsightly.

[0005] 2. The high-voltage wire harnesses at the outlet ends of the motor controller, battery high-voltage cabinet, and four-in-one controller are suspended after being bundled with cable ties. Gravity acts on the outlet ends of the high-voltage wire harnesses of the motor controller, battery high-voltage cabinet, and four-in-one controller. In the long run, they will damage the outlet ends of the high-voltage wire harnesses of the motor controller, battery high-voltage cabinet, and four-in-one controller, which will affect the performance of the motor controller, battery high-voltage cabinet, and four-in-one controller. Moreover, the position of the high-voltage wire harnesses is not uniform after bundling, and the appearance is poor.

[0006] 3. There is a certain distance between the high-voltage harness connector of the power battery and the harness fixing point on the power battery in both the horizontal and vertical directions. Directly using a cable tie to bundle the high-voltage harness with the harness fixing point will cause the bundled high-voltage harness to be slanted, making the routing of the high-voltage harness unsightly.

[0007] 4. If the high-voltage wire harness in the air duct is bundled and fixed with an insulating wire clamp, it is not only complicated to operate and has poor aesthetics, but also cannot effectively separate the high-voltage wire harness in the air duct from the low-voltage wire harness in the air duct (the space in the air duct is limited, and the existing bundling method makes the bundled high-voltage wire harness and the low-voltage wire harness very close to each other), which makes the two have the hidden danger of mutual interference. Summary of the invention

[0008] In view of the problems existing in the prior art, the embodiment of the present invention proposes an automobile high-voltage wire harness fixing bracket group, which not only makes the bundling operation of the high-voltage wire harness simple and convenient, but also makes the bundled high-voltage wire harness more aesthetically pleasing.

[0093] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0094] The electric vehicle includes a motor controller 110, a battery high voltage cabinet 210, a four-in-one controller 310, a power battery 410, an air duct, and a high-voltage wire harness arranged therebetween. In order to make the high-voltage wire harness arrangement in the vehicle reasonable and clear, it is necessary to bundle and fix the high-voltage wire harness between the motor controller 110, the battery high voltage cabinet 210, the four-in-one controller 310, the power battery 410, and the air duct. The present invention uses an automobile high-voltage wire harness fixing bracket group to bundle and fix the high-voltage wire harness between the motor controller 110, the battery high voltage cabinet 210, the four-in-one controller 310, the power battery 410, and the air duct.

[0095] Embodiment 1: A vehicle high-voltage wire harness fixing bracket group includes a first bracket 100 arranged in cooperation with a motor controller 110, a second bracket 200 arranged in cooperation with a battery high-voltage cabinet 210, a third bracket 300 arranged in cooperation with a four-in-one controller 310, a fourth bracket 400 arranged in cooperation with a power battery 410, a fifth bracket 500 arranged in cooperation with an air duct, and a universal bracket 600 for bundling and fixing high-voltage wire harnesses between the motor controller 110, the battery high-voltage cabinet 210, the four-in-one controller 310, the power battery 410, and the air duct.

[0096] like Figure 1 As shown, the first bracket 100 includes a first bracket connecting portion 101, a first bracket height adjustment portion 102 and a first bracket harness mounting portion 103 which are integrally formed. The first bracket connecting portion 101 is used to connect with the mounting frame 120 of the motor controller 110. The first bracket height adjustment portion 102 is connected to the first bracket connecting portion 101. The first bracket harness mounting portion 103 is connected to the first bracket height adjustment portion 102 and is used to connect with the high-voltage harness led out of the high-voltage harness outlet of the motor controller 110, and the motor controller 110 has a row of high-voltage harness outlets.

[0097] Specifically, Figures 1 to 3 and Figure 5As shown, the first bracket connection part 101 includes a first bracket connection plate, which is horizontally arranged and has a thickness of 3 mm. The first bracket connection plate is provided with a first bracket assembly hole 101-1 connected and fixed to the existing mounting frame 120. One or more first bracket assembly holes 101-1 may be provided, and the first bracket assembly holes 101-1 may be circular or elongated. When used, it is only necessary to first place the first bracket connection plate horizontally on the top surface of the mounting frame 120, and then rivet the rivet into the first bracket assembly hole 101-1 by a rivet gun until the rivet connects and fixes the first bracket connection plate to the mounting frame 120.

[0098] The first bracket height adjustment part 102 includes a first bracket height adjustment plate, which is arranged at a certain angle with the first bracket connecting plate (the angle can be less than 90 degrees or equal to 90 degrees), and the bottom side of the first bracket height adjustment plate is connected to one side of the first bracket connecting plate, and the thickness of the first bracket height adjustment plate is 3 mm. There is a certain height difference between the top surface of the mounting frame 120 and the high-voltage wire harness outlet of the motor controller 110, so it is necessary to increase the height of the first bracket harness mounting part 103 through the first bracket height adjustment plate, so that the high-voltage wire harness led out of the high-voltage wire harness outlet of the motor controller 110 can be placed horizontally on the first bracket harness mounting part 103.

[0099] The first bracket harness installation part 103 includes a first bracket harness main support plate connected to the top side of the first bracket height adjustment plate, and a plurality of first bracket harness installation plates connected to the first bracket harness main support plate. The first bracket harness main support plate and the first bracket harness installation plate are both arranged horizontally, and their thickness is 3 mm. A first bracket 100 can be provided with three first bracket harness installation plates (such as Figure 1 As shown), five first bracket harness mounting plates (such as Figure 2 As shown), one of the first bracket harness mounting plates corresponds to a high-voltage harness led out from a high-voltage harness outlet terminal.

[0100] like Figure 4As shown, after the high-voltage wire harness is placed on the first bracket wire harness mounting plate, the high-voltage wire harness also needs to be connected and fixed to the first bracket wire harness mounting plate through a wire harness connector 800, and the wire harness connector 800 can be a cable tie. In order to prevent the cable tie from falling off the free end of the first bracket wire harness mounting plate after long-term use, it is necessary to open a wire harness connector limiting groove on both sides of the first bracket wire harness mounting plate. After the cable tie connects and fixes the first bracket wire harness mounting plate to the high-voltage wire harness, the cable tie will be firmly limited in the wire harness connector limiting groove, so that the first bracket wire harness mounting plate and the high-voltage wire harness can be stably connected for a long time. In addition, the free end of the first bracket wire harness mounting plate can be bent obliquely downward, which can prevent the free end of the first bracket wire harness mounting plate from causing wear to the high-voltage wire harness under long-term use.

[0101] The embodiment of the present invention uses a first bracket 100 and a cable tie to connect and fix the high-voltage wire harness led out from the high-voltage wire harness outlet of the motor controller 110, so that the gravity of the high-voltage wire harness after being bundled and fixed can act on the first bracket 100 (rather than on the high-voltage wire harness outlet of the motor controller 110), thereby protecting the high-voltage wire harness outlet of the motor controller 110, allowing the motor controller 110 to be effectively used for a long time, and making the bundled high-voltage wire harness highly aesthetic.

[0102] like Figure 6 As shown, the second bracket 200 includes a second bracket connection portion 201, a second bracket harness mounting portion 1 202 and a second bracket harness mounting portion 2 203 that are integrally formed. The second bracket connection portion 201 is used to connect to the mounting frame 2 220 of the battery high-voltage cabinet 210. The second bracket harness mounting portion 1 202 is connected to the second bracket connection portion 201 and is used to connect to the high-voltage harness led out of the high-voltage harness outlet terminal on the first side of the battery high-voltage cabinet 210. The second bracket harness mounting portion 203 is connected to the second bracket connection portion 201 and is used to connect to the high-voltage harness led out of the high-voltage harness outlet terminal on the second side of the battery high-voltage cabinet 210. The first side of the battery high-voltage cabinet 210 has a row of high-voltage harness outlet terminals, and the second side of the battery high-voltage cabinet 210 has a high-voltage harness outlet terminal.

[0103] like Figure 6 and Figure 7As shown, the second bracket connection part 201 includes a second bracket connection plate, which is vertically arranged and has a thickness of 3 mm. The second bracket connection plate is provided with a second bracket assembly hole 201-1 connected to the second mounting frame 220. Two or more second bracket assembly holes 201-1 can be provided, and the second bracket assembly hole 201-1 can be circular or elongated. When used specifically, it is only necessary to first abut the second bracket connection plate against the first side surface of the second mounting frame 220, and then rivet the rivet into the second bracket assembly hole 201-1 by a rivet gun until the rivet connects and fixes the second bracket connection plate to the second mounting frame 220.

[0104] like Figure 6 and Figure 7 As shown, the second bracket harness mounting portion 202 includes a second bracket harness mounting plate 1, which is vertically arranged and has a thickness of 3 mm. The second bracket harness mounting plate 1 is connected to the bottom side of the second bracket connecting plate. A second bracket 200 can be provided with three second bracket harness mounting plates 1 (such as Figure 6 As shown), one of the second bracket harness mounting plates is connected to a high-voltage harness led out from a high-voltage harness outlet terminal.

[0105] The second support harness mounting plate 1 corresponds to the high-voltage harness outlet on the first side of the battery high-voltage cabinet 210. When the high-voltage harness is placed on the second support harness mounting plate 1, the high-voltage harness needs to be connected and fixed to the second support harness mounting plate 1 through the harness connector 800. The harness connector 800 can be a cable tie. In order to prevent the cable tie from falling off from the free end of the second support harness mounting plate 1 after long-term use, it is necessary to open a harness connector limit groove on both sides of the second support harness mounting plate 1. When the cable tie connects and fixes the second support harness mounting plate 1 to the high-voltage harness, the cable tie will be firmly limited in the harness connector limit groove, so that the second support harness mounting plate 1 and the high-voltage harness can be stably connected for a long time. In addition, the free end of the second support harness mounting plate 1 can be bent obliquely inward (facing the direction of the battery high-voltage cabinet 210), which can prevent the free end of the second support harness mounting plate 1 from causing wear to the high-voltage harness under long-term use.

[0106] like Figure 6 and Figure 7 As shown, the second bracket wire harness mounting portion 203 includes a second bracket wire harness mounting plate 2, which is vertically arranged and has a thickness of 3 mm. The second bracket wire harness mounting plate 2 is connected to the vertical side of the second bracket connecting plate at a certain angle, and the second bracket wire harness mounting plate 2 is provided with a group of wire harness connecting hole pairs 203-1, and the high-voltage wire harness is connected to the wire harness connecting hole pairs 203-1 through a wire harness connector 800.

[0107] The second support harness mounting plate 2 corresponds to the high-voltage harness outlet terminal on the second side of the battery high-voltage cabinet 210, and the harness connection hole pair 203-1 includes two harness connection holes that are symmetrically arranged on the left and right, and the position between the two harness connection holes is used to place the high-voltage harness. When the high-voltage harness is placed on the second support harness mounting plate 2 and is located between the two harness connection holes, the high-voltage harness also needs to be connected and fixed to the second support harness mounting plate 2 through the harness connector 800. The harness connector 800 can be a cable tie, and when connecting, it is only necessary to first pass the cable tie through the two harness connection holes, and then connect and fix the cable tie. In addition, in order to facilitate the installation of the cable tie, the harness connection hole can be connected to the side of the second support harness mounting plate 2.

[0108] The embodiment of the present invention uses a second bracket 200 and a cable tie to connect and fix the high-voltage wire harness led out of the high-voltage wire harness outlet of the battery high-voltage cabinet 210, so that the gravity of the high-voltage wire harness after being bundled and fixed can act on the second bracket 200 (rather than on the high-voltage wire harness outlet of the battery high-voltage cabinet 210), thereby protecting the high-voltage wire harness outlet of the battery high-voltage cabinet 210, so that the battery high-voltage cabinet 210 can be used effectively for a long time, and the bundled high-voltage wire harness has a high aesthetics.

[0109] like Figure 8 and Fig. 9 As shown, the third bracket 300 includes a third bracket connecting portion 301, a third bracket supporting portion 302 and a third bracket harness mounting portion 1 303 which are integrally formed, and a third bracket harness mounting portion 2 304 which is welded and fixed to the third bracket supporting portion 302. The third bracket connecting portion 301 is used to connect with the inherent mounting hole 310-1 on the four-in-one controller 310. The third bracket supporting portion 302 is connected to the third bracket connecting portion 301 in a one-to-one correspondence. The third bracket harness mounting portion 1 303 is connected to the two third bracket supporting portions 302 and is used to connect with the high-voltage harness led out of the first row of high-voltage harness outlets of the four-in-one controller 310. The third bracket harness mounting portion 2 304 is connected to the two third bracket supporting portions 302 and is used to connect with the high-voltage harness led out of the second row of high-voltage harness outlets of the four-in-one controller 310. The same side of the four-in-one controller 310 has two rows of upper and lower high-voltage wire harness outlet terminals, and the shell of the four-in-one controller 310 has two left-right symmetrical horizontal shell plates, each of which has an inherent mounting hole 310-1.

[0110] The third bracket connection part 301 includes two third bracket connection plates, which are horizontally arranged and have a thickness of 3 mm. Each third bracket connection plate is provided with a third bracket assembly hole 301-1 connected to the inherent mounting hole 310-1 through a connecting piece. The third bracket assembly hole 301-1 can be circular or elongated, and the connecting piece can be a bolt and a nut. When in use, it is only necessary to first place the third bracket connection plate horizontally on the bottom surface of the horizontal shell plate, and align the third bracket assembly hole 301-1 with the inherent mounting hole 310-1, and finally connect and fix the third bracket assembly hole 301-1 on the third bracket connection plate with the inherent mounting hole 310-1 on the horizontal shell plate through bolts and nuts.

[0111] The third bracket support part 302 includes two third bracket support plates, which are vertically arranged and have a thickness of 3 mm, and each third bracket support plate is vertically connected to the corresponding third bracket connecting plate. There is a certain height difference between the horizontal shell plate and the high-voltage wire harness outlet of the four-in-one controller 310. Therefore, the height of the third bracket wire harness installation part 1 303 and the third bracket wire harness installation part 2 304 needs to be increased by the third bracket support plate, so that the high-voltage wire harness led out of the high-voltage wire harness outlet of the four-in-one controller 310 can be horizontally placed on the third bracket wire harness installation part 1 303 or the third bracket wire harness installation part 2 304.

[0112] like Figure 8 As shown, the third bracket harness mounting portion 303 includes a third bracket harness main support plate 1 connected to the two third bracket support plates, and a plurality of third bracket harness mounting plates 1 connected to the third bracket harness main support plate 1. The third bracket harness main support plate 1 and the third bracket harness mounting plate 1 are both horizontally arranged, and their thickness is 3 mm. A third bracket 300 can be provided with four third bracket harness mounting plates 1 (such as Figure 8 As shown), one of the third bracket harness mounting plates is connected to a high-voltage harness led out from a high-voltage harness outlet terminal.

[0113] After the high-voltage wire harness is placed on the third-support wire harness mounting plate 1, the high-voltage wire harness also needs to be connected and fixed to the third-support wire harness mounting plate 1 through the wire harness connector 800. The wire harness connector 800 can be a cable tie. In order to prevent the cable tie from falling off the free end of the third-support wire harness mounting plate 1 after long-term use, it is necessary to open wire harness connector limiting grooves on both sides of the third-support wire harness mounting plate 1. After the cable tie connects and fixes the third-support wire harness mounting plate 1 to the high-voltage wire harness, the cable tie will be firmly limited in the wire harness connector limiting groove, so that the third-support wire harness mounting plate 1 and the high-voltage wire harness can be stably connected for a long time. In addition, if Fig.10As shown, the free end of the third bracket harness mounting plate 1 can be bent obliquely downward, which can prevent the free end of the third bracket harness mounting plate 1 from wearing the high-voltage harness due to long-term use.

[0114] like Figure 8 As shown, the third bracket harness mounting portion 2 304 includes a third bracket harness main support plate 2 connected to the two third bracket support plates, and a plurality of third bracket harness mounting plates 2 connected to the third bracket harness main support plate 2. The third bracket harness main support plate 2 and the third bracket harness mounting plate 2 are both arranged horizontally, and their thickness is 3 mm. A third bracket 300 can be provided with four third bracket harness mounting plates 2 (such as Figure 8 As shown), one of the third bracket harness mounting plates 2 corresponds to a high-voltage harness led out from a high-voltage harness outlet terminal.

[0115] After the high-voltage wire harness is placed on the third support wire harness mounting plate 2, the high-voltage wire harness also needs to be connected and fixed to the third support wire harness mounting plate 2 through the wire harness connector 800, and the wire harness connector 800 can be a cable tie. In order to prevent the cable tie from falling off the free end of the third support wire harness mounting plate 2 after long-term use, it is necessary to open a wire harness connector limiting groove on both sides of the third support wire harness mounting plate 2. After the cable tie connects and fixes the third support wire harness mounting plate 2 to the high-voltage wire harness, the cable tie will be firmly limited in the wire harness connector limiting groove, so that the third support wire harness mounting plate 2 and the high-voltage wire harness can be stably connected for a long time. In addition, the free end of the third support wire harness mounting plate 2 can be bent obliquely downward, which can prevent the free end of the third support wire harness mounting plate 2 from causing wear to the high-voltage wire harness under long-term use.

[0116] The embodiment of the present invention uses a third bracket 300 and a cable tie to connect and fix the high-voltage wire harness led out from the high-voltage wire harness outlet of the four-in-one controller 310, so that the gravity of the high-voltage wire harness after being bundled and fixed can act on the third bracket 300 (rather than on the high-voltage wire harness outlet of the four-in-one controller 310), thereby protecting the high-voltage wire harness outlet of the four-in-one controller 310, allowing the four-in-one controller 310 to be effectively used for a long time, and making the bundled high-voltage wire harness highly aesthetic.

[0117] like Fig.11As shown, the fourth bracket 400 includes a fourth bracket support plate 401. The fourth bracket support plate 401 is horizontally arranged, and its thickness is 2 mm. The fourth bracket support plate 401 is provided with a plurality of position limiting installation parts 401-1 at intervals along its length direction. The position limiting installation parts 401-1 are connected to the high-voltage wire harness led out of the high-voltage wire harness plug-in terminal 410-2 of the power battery 410 through the wire harness connector 800, and the fourth bracket support plate 401 is also connected to the wire harness fixing body 410-1 on the power battery 410 through the position limiting installation parts 401-1 and the wire harness connector 800.

[0118] like Fig.13 As shown, the power battery 410 has two upper and lower high-voltage harness plug-in terminals 410-2, and the shell of the power battery 410 has two harness fixing bodies 410-1 that are symmetrically arranged on the left and right, and the harness fixing bodies 410-1 also have harness fixing holes. The harness connector 800 can be a cable tie, and the limiting mounting portion 401-1 can be a limiting mounting hole. When in use, first place the fourth bracket support plate 401 horizontally on the top surface of the harness fixing body 410-1, and then connect and fix the harness fixing holes on the harness fixing body 410-1 to the corresponding limiting mounting holes on the fourth bracket support plate 401 through cable ties. Then, as shown in FIG. Fig.14 As shown, the high-voltage wire harness led out from the high-voltage wire harness plug-in terminal 410-2 is placed along the length direction of the fourth bracket support plate 401. Finally, the high-voltage wire harness is connected and fixed to the limiting mounting hole on the fourth bracket support plate 401 through a cable tie.

[0119] The embodiment of the present invention uses the fourth bracket 400 and the cable tie to connect and fix the high-voltage wire harness led out of the high-voltage wire harness plug-in terminal 410-2 of the power battery 410, so that the high-voltage wire harness can be arranged horizontally and vertically, thereby improving the aesthetics of the high-voltage wire harness routing.

[0120] like Fig.15 and Fig.16 As shown, the fifth bracket 500 includes a fifth bracket connecting portion 501, a fifth bracket harness mounting portion 1 502 and a fifth bracket harness mounting portion 2 503 which are integrally formed. The fifth bracket connecting portion 501 is used to connect to the inner wall of the air duct. The fifth bracket harness mounting portion 1 502 is connected to the fifth bracket connecting portion 501 and is used to connect to a part of the high-voltage harness in the air duct. The fifth bracket harness mounting portion 2 503 is connected to the two fifth bracket harness mounting portions 1 502 and is used to connect to another part of the high-voltage harness in the air duct.

[0121] like Fig.15As shown, the fifth bracket connection part 501 includes two fifth bracket connection plates, which are arranged vertically and have a thickness of 2 mm. Each third bracket connection plate is provided with at least two fifth bracket assembly holes 501-1 connected to the inner wall of the air duct, and the fifth bracket assembly hole 501-11 can be circular. When installing, first place the fifth bracket connection plate against the inner wall of the air duct, and then rivet the rivet into the fifth bracket assembly hole 501-1 with a rivet gun until the rivet connects and fixes the fifth bracket connection plate to the air duct wall.

[0122] like Fig.15 As shown, the fifth bracket harness mounting portion 502 includes two fifth bracket harness mounting plates 1, the fifth bracket harness mounting plates 1 are horizontally arranged, the thickness is 2 mm, each fifth bracket harness mounting plate 1 is vertically connected to the corresponding fifth bracket connecting plate 1, and each fifth bracket harness mounting plate 1 is provided with two sets of harness mounting holes 502-1. The high-voltage harness passing through the air duct can be connected and fixed with any set of harness mounting holes 502-1 through the harness connector 800. Each set of harness mounting holes 502-1 includes two harness mounting holes arranged symmetrically on the left and right, and the position between the two harness mounting holes is used to place the high-voltage harness. When the high-voltage harness is placed on the fifth bracket harness mounting plate 1 and located between the two harness mounting holes, the high-voltage harness is connected and fixed with the fifth bracket harness mounting plate 1 through the harness connector 800. The harness connector 800 can be a cable tie, and when connecting, it is only necessary to first pass the cable tie through the two harness mounting holes, and then connect and fix the cable tie.

[0123] like Fig.15 As shown, the fifth bracket harness mounting portion 2 503 includes a fifth bracket harness main support plate 2 vertically connected to the two fifth bracket harness mounting plates 1, and a plurality of fifth bracket harness mounting plates 2 connected to the fifth bracket harness main support plate 2. The fifth bracket harness main support plate 2 and the fifth bracket harness mounting plate 2 are both vertically arranged, and their thicknesses are both 2 mm. The fifth bracket harness main support plate 2 is provided on both long sides of the fifth bracket harness main support plate 2. A fifth bracket 500 can be provided with five fifth bracket harness mounting plates 2 on both long sides of the fifth bracket harness main support plate 2 according to usage requirements.

[0124] like Fig.16As shown, the fifth support harness mounting plate 2 is connected to a corresponding high-voltage harness (some high-voltage harnesses can be placed on the first side of the fifth support harness mounting plate 2, and some high-voltage harnesses can be placed on the second side of the fifth support harness mounting plate 2). After the high-voltage harness that has passed through the air duct is placed on the fifth support harness mounting plate 2, the high-voltage harness needs to be connected and fixed to the fifth support harness mounting plate 2 through a harness connector 800, which can be a cable tie. In order to prevent the harness from falling off from the free end of the fifth support harness mounting plate 2 after long-term use, it is necessary to open harness connector limit grooves on both sides of the fifth support harness mounting plate 2. After the harness connects and fixes the fifth support harness mounting plate 2 to the high-voltage harness, the harness will be firmly limited in the harness connector limit groove, so that the fifth support harness mounting plate 2 and the high-voltage harness can be stably connected for a long time.

[0125] The embodiment of the present invention uses the fifth bracket 500 and the cable tie to connect and fix the high-voltage wire harness in the air duct, which is not only easy to operate and aesthetically pleasing, but also can effectively separate the high-voltage wire harness in the air duct from the low-voltage wire harness in the air duct so that the two will not interfere with each other.

[0126] like Fig.17 and Fig.18 As shown, the universal bracket 600 includes an integrally formed universal bracket main support portion 601 and a universal bracket harness mounting portion 602 connected to the universal bracket main support portion 601. The universal bracket harness mounting portion 602 is symmetrically arranged along the universal bracket main support portion 601, and the two symmetrically arranged universal bracket harness mounting portions 602 are used to connect the same high-voltage harness.

[0127] Specifically, the universal bracket main support part 601 includes a universal bracket main support plate, the thickness of the universal bracket main support plate is 3 mm, and the universal bracket main support plate is provided with a plurality of universal bracket mounting holes 1 601-1. The universal bracket harness mounting part 602 includes a universal bracket harness mounting plate, and the two long sides of the universal bracket main support plate are symmetrically connected with universal bracket harness mounting plates (the two symmetrically arranged universal bracket harness mounting plates are used to connect a high-voltage harness together). The universal bracket harness mounting plate and the universal bracket main support plate are located in the same plane, the thickness of the universal bracket harness mounting plate is 3 mm, and each universal bracket harness mounting plate is provided with a universal bracket mounting hole 2 602-1.

[0128] There are various arrangements of the high-voltage wire harnesses between the motor controller 110, the battery high-voltage cabinet 210, the four-in-one controller 310, the power battery 410, and the air duct. For example, some high-voltage wire harnesses are arranged vertically from top to bottom, and some high-voltage wire harnesses are arranged horizontally from left to right. The universal bracket 600 of the embodiment of the present invention only needs to change its placement method to be connected to various high-voltage wire harnesses to be bundled in different arrangements, and has strong versatility.

[0129] When installing the universal bracket 600, first determine the placement of the universal bracket 600 according to the arrangement of the high-voltage wire harness to be bundled, and then contact the universal bracket 600 with nearby brackets (for example, Fig.19 , Fig. 20 As shown), finally, rivets are riveted into some universal bracket mounting holes 1 601-1 and / or some universal bracket mounting holes 2 602-1 by a rivet gun until the rivets connect and fix the universal bracket 600 to the nearby brackets.

[0130] When bundling the high-voltage wire harness, first place the high-voltage wire harness on the universal support wire harness mounting plate (and one high-voltage wire harness is placed on two symmetrical universal support wire harness mounting plates), and then the high-voltage wire harness needs to be connected and fixed to the universal support wire harness mounting plate through the wire harness connector 800, which can be a cable tie. In order to prevent the cable tie from falling off the free end of the universal support wire harness mounting plate after long-term use, it is necessary to open a wire harness connector limiting groove on both sides of the universal support wire harness mounting plate. After the cable tie connects and fixes the universal support wire harness mounting plate to the high-voltage wire harness, the cable tie will be firmly limited in the wire harness connector limiting groove, so that the universal support wire harness mounting plate and the high-voltage wire harness can be stably connected for a long time.

[0131] The embodiment of the present invention uses a universal bracket 600 and a cable tie to bundle and fix the high-voltage wire harnesses between the motor controller 110, the battery high-voltage cabinet 210, the four-in-one controller 310, the power battery 410, and the air duct. It is not only highly universal, but also makes the bundling operation of the high-voltage wire harness simple and convenient, and also makes the bundled high-voltage wire harness horizontal and vertical, and highly aesthetic.
