Description

Technical Field

[0001] The utility model relates to the technical field related to wiring harness installation, in particular to an auxiliary bracket for installing a door wiring harness. Background Art

[0002] There are usually multiple wiring harnesses on the car door, such as the window lift function key wiring harness, door lock control wiring harness, B-PEPS wiring harness, etc. Taking the B-PEPS wiring harness as an example, the B-PEPS antenna (used to receive and unlock the vehicle signal) is often arranged on the outside of the car door panel. To ensure that the signal is not interfered with, the B-PEPS antenna can only be arranged on the outside of the door sheet metal. The B-PEPS antenna usually comes with a wiring harness pre-installed on the plastic exterior panel of the door. The wiring harness branch inside the car that is connected to the B-PEPS antenna's own wiring harness needs to pass through the opening in the bottom area of ​​the door before it can be installed and connected. The lower body structure of the car door will be affected by different external styling surfaces, resulting in different Y-direction spaces formed by the door inner panel and the door outer panel in the opening area. The wiring harness branching inside the car relies on the Y-direction space to enable the fingers to operate the auxiliary wiring harness branch through the through holes opened in the door outer panel; when the Y-direction of the external styling surface of a certain model door is more inward, it will inevitably cause the Y-direction space mentioned above to become smaller, thereby affecting the wiring harness perforation zone on the outside of the door, which may cause the wiring harness perforation time to be too long, which will not be able to meet the working hours of the existing door assembly line, and ultimately affect the production and manufacturing of the entire production line.

[0003] At present, the difficulty of installing the harness through holes has affected the working hours. Because the inner Y-direction of the door sheet metal is almost impossible to adjust, the outer boundary of the side panel is almost impossible to adjust. On the one hand, the outer shape is required to be as small as possible in the Y direction (up to 3-5mm), and the amount of shape adjustment is very limited. Too much adjustment will affect the overall outer shape, which is unacceptable. Moreover, the 3-5mm adjustment amount will only improve the hand operation space insignificantly. The size of the finger itself with gloves will be 25-30mm. The operating space basically requires more than 40mm of Y-direction installation space to facilitate the fingers to assist in the installation. When the Y-direction gap is less than 35mm, the production line basically relies on overcoming it to perform the harness through hole operation and installation, which makes it difficult for the harness installation working hours to meet the existing production rhythm. In fact, the Y-axis clearance here may be reduced to the design limit of 15mm. In this case, human fingers cannot assist in installation, and it can only be installed by trial and error. There is a high probability that the wiring harness will be pushed to the bottom of the sheet metal structure inside and outside the car door and stuck. The comprehensive installation time will far exceed the existing beat, which cannot meet normal growth and manufacturing, resulting in the production line being shut down and waiting.

[0004] In the solutions disclosed in the prior art, for example, the Chinese patent with application number CN201920510291.7 discloses a car door harness fixing bracket. The car door harness fixing bracket disclosed in the patent can save space in a more integrated manner, which is conducive to the refinement of automobile parts, but it cannot solve the problem of difficulty in punching the door harness.

[0039] First, the problem of inconvenience in punching holes in door sheet metal for door wiring harnesses in the prior art is explained. Taking the installation punching holes of the B-PEPS antenna wiring harness on the door as an example, B-PEPS antennas (used to receive and unlock vehicle signals) are often arranged on the outside of car door panels. To ensure that the signal is not interfered with, B-PEPS antennas can only be arranged on the outside of door sheet metals. B-PEPS antennas usually come with a wiring harness pre-installed on the plastic exterior panel of the door. The wiring harness branch inside the car that is docked with the B-PEPS antenna's own wiring harness needs to pass through the opening in the bottom area of ​​the door before it can be installed and docked.

[0040] However, when the wiring harness of the B-PEPS antenna is connected and passes through the opening in the bottom area of ​​the door, it is necessary to extend through the gap between the inner and outer sheet metal of the door, and then pass through the opening and connect with the wiring harness branch. However, the gap size between the inner and outer sheet metal of the door is generally uncontrollable. For example, when the width of the gap is less than 30 mm, it is difficult to use fingers to assist in perforating the gap, and the only option is to try to perforate and install it by trial and error. When perforating in this way, the wiring harness head is easily stuck in the gap between the inner and outer sheet metal of the door, making it impossible for the wiring harness to pass through, and the wiring harness perforation efficiency is extremely low, making it difficult to meet the rhythm manufacturing requirements of the door sub-assembly production line.

[0041] In order to solve the above technical problems, the present application discloses an auxiliary bracket for installing a door wiring harness. The auxiliary bracket is provided with an inclined guide portion, and a guide groove is provided in the guide portion. When in use, the guide portion passes through the wiring harness installation hole and extends into the gap of the door sheet metal, providing the door wiring harness with an auxiliary guide structure when punching. The door wiring harness is assisted in guiding by the guide portion and the guide groove when passing through the wiring harness installation hole. Even if the gap is less than 30 mm, the wiring harness can be quickly punched through the auxiliary bracket. The auxiliary bracket disclosed in the present application is explained in detail below:

[0042] The implementation of this embodiment discloses an auxiliary bracket for installing the door harness 8, see Figure 1 and Figure 2 The auxiliary bracket includes a bracket body, which includes a support plate 1 and a guide portion 2 integrally arranged at one end of the support plate 1. The support plate 1 extends in a direction parallel to the extension direction of the door sheet metal 3. The guide portion 2 extends from one end of the support plate 1 toward the door sheet metal 3, wherein a guide groove 21 is provided on the side of the guide portion 2 away from the support plate 1, and the guide groove 21 passes through the guide portion 2 and has both ends open outward.

[0043] When the bracket body is positioned at the outside of the door sheet metal 3 , the guide portion 2 is aligned with the wiring harness installation hole 32 on the door sheet metal 3 and extends into the wiring harness installation hole 32 .

[0044] Specifically, the guide portion 2 may be provided with a guide plate, a guide block, a guide rail, etc., and the guide groove 21 may also be a guide rail groove, etc., provided on the guide portion 2. It should be noted that, in the present embodiment, the guide groove 21 provided on the guide portion 2 has the following function: when the guide portion 2 is aligned with the harness mounting hole 32 on the door sheet metal 3 and extends into the harness mounting hole 32, the guide portion 2 is filled in the gap between the inner and outer sheet metals of the door, and the guide groove 21 guides the door harness 8. A person skilled in the art may set the angle between the extension direction of the support plate 1 and the guide groove 21 to an obtuse angle, a right angle, or an acute angle slightly less than a right angle according to the requirements to receive and assist in guiding the harness. In one of the preferred embodiments, the angle between the extension direction of the support plate 1 and the guide groove 21 is an obtuse angle, which is more conducive to the guide groove guiding the door harness, and the present embodiment does not make any specific limitation on this.

[0045] Therefore, the present embodiment discloses an auxiliary bracket specially used for installing the door wiring harness 8, specifically, an auxiliary bracket for assisting the door wiring harness 8 to pass through the wiring harness mounting hole 32 in the slit of the door sheet metal 3. When the auxiliary bracket is in use, the bracket body is positioned on the outside of the door sheet metal 3, and then the guide part 2 is aligned with the wiring harness mounting hole 32 and extended into the wiring harness mounting hole 32. The guide groove 21 of the guide part 2 extends in the slit of the door sheet metal 3. When punching, the end of the door wiring harness 8 falls into the guide groove 21 in the gap and is further guided by the guide groove 21 to the wiring harness mounting hole 32, and then passes through the wiring harness mounting hole 32. The auxiliary bracket has the advantages of simple structure and easy use, which solves the problem of inconvenience in punching the door wiring harness 8 in the door sheet metal 3, and can greatly improve the efficiency of punching the door wiring harness 8.

[0046] The implementation of this embodiment also discloses an auxiliary bracket for installing the door wiring harness 8, see Figure 1 and Figure 2 The guide part 2 is an arc-shaped plate structure as a whole, and the cross section of the guide part 2 is a "U" shape with two sides extending out and the middle recessed, and the guide part 2 forms a guide groove 21 as a whole. When the bracket body is positioned outside the door sheet metal 3, the outer walls of the guide part 2 on both sides abut against the inner walls of the harness installation hole 32 on both sides, and the outer end surface of the connecting part of the guide part 2 and the support plate 1 fits with the corresponding inner wall of the harness installation hole 32.

[0047] With such a structure, the guide part 2 is an arc-shaped plate structure as a whole. When the wiring harness falls on the guide part 2, it can easily slide down by gravity or be quickly pulled out by manual assistance. When the cross-section of the guide part 2 is a "U" shape with protruding sides and recessed in the middle, the guide part 2 has the largest receiving area in the gap of the door sheet metal 3. The outer walls on both sides of the guide part 2 are respectively abutted against the inner walls on both sides of the wiring harness mounting hole 32, and the outer end surface of the guide part 2 at the connection with the support plate 1 is fitted with the corresponding inner wall of the wiring harness mounting hole 32, which can further ensure that the guide part 2 and the wiring harness mounting hole 32 are fitted, and in order to improve the guiding effect of the guide groove 21, the guide groove 21 is further set to a smooth surface in this embodiment.

[0048] In one preferred embodiment, when looking from one side of the bracket body toward the bracket body, the angle between the support plate 1 and the extension direction of the guide groove 21 is an obtuse angle, and the angle is in the range of 110° to 160°.

[0049] For example, the angle between the support plate 1 and the extension direction of the guide groove 21 can be 110°, 120°, 135°, 160°, etc. Setting it to an obtuse angle is conducive to the door wiring harness 8 sliding along the direction of the guide groove 21 to the side of the wiring harness mounting hole 32 under the action of gravity. Technical personnel in this field can design and select according to actual needs, and this embodiment does not make specific limitations on this.

[0050] In another preferred embodiment, the length dimension of the guide portion 2 extending out of the support plate 1 is greater than the width dimension of the sheet metal gap 31 inside the door sheet metal 3. When the bracket body is positioned outside the door sheet metal 3, the portion of the guide portion 2 extending into the harness mounting hole 32 fills the entire width gap of the sheet metal gap 31. The width direction of the sheet metal gap is as shown in FIG. Figure 3 and Figure 5 As shown in the A direction.

[0051] Specifically, the width of the sheet metal gap 31 in this embodiment refers to the width of the gap between the inner sheet metal and the outer sheet metal of the same door. Figure 3 and Figure 5 As shown, more specifically, taking the installation of the wiring harness of the B-PEPS antenna on the door sheet metal 3 as an example, the size of the sheet metal gap 31 at this time refers to the gap size at the corresponding part of the wiring harness installation hole 32 through which the wiring harness of the B-PEPS antenna passes, that is, the gap size between the inner and outer sheet metals of the door near the bottom. Specifically, the width dimension of the sheet metal gap 31 at this time is the dimension in the thickness direction of the door sheet metal 3, which is the gap size of the door along the Y direction in the vehicle body coordinate system.

[0052] Furthermore, for example, the length of the guide portion 2 extending out of the support plate 1 is greater than any value of the width of the sheet metal gap 31 within the range of 5 to 15 mm, such as greater than 5 mm, 10 mm, 15 mm, etc., to provide a redundant value for the use of the auxiliary bracket, and can be adapted to the gap sizes of different vehicle doors, and the portion of the guide portion 2 extending into the wiring harness mounting hole 32 fills the width gap of the entire sheet metal gap 31, ensuring that the door wiring harness 8 falls into the guide groove 21 on the guide portion 2 when punching a hole in the gap, further ensuring the success rate of punching the door wiring harness 8.

[0053] The implementation method of this embodiment also discloses an auxiliary bracket for installing a door wiring harness 8. On the basis of the above embodiment, it also includes a magnetic component, which is arranged on one side of the support plate 1. The bracket body is positioned on the outer side of the door sheet metal 3 by adsorption of the magnetic component.

[0054] Furthermore, a handheld component is also included, and one end of the support plate 1 away from the guide portion 2 is detachably attached to the end of the handheld component.

[0055] Specifically, in the present embodiment, the magnetic attraction component utilizes the electromagnetic principle of the tooling. Before installing the door wiring harness 8, an iron clip can be pre-installed on the wiring harness head. The wiring harness head with the iron clip automatically slides into the guide groove 21 in the gap due to the attraction of the magnetic attraction component. After the wiring harness head is sent to the guide groove 21, it can directly slide out under the action of gravity to realize the quick punching function.

[0056] In another preferred embodiment of the present invention, the handheld assembly includes an integrally formed handheld portion 5 and a mounting portion 6, and the mounting portion 6 is located near one side of the bracket body. A mounting platform 61 protruding from the plane where the mounting portion 6 is located is provided on one side of the mounting portion 6, and the bracket body is provided on the mounting platform 61, and the handheld portion 5 includes a gripping handle. Moreover, when looking from the top of the handheld assembly toward the handheld assembly, the width dimension of the gripping handle is smaller than the width dimension of the mounting portion 6.

[0057] In one preferred embodiment, the magnetic attraction component includes an electromagnet 70 disposed on one side of the support plate 1, and the handheld assembly also includes a rechargeable battery 71 and a switch button 72, and the rechargeable battery 71 is electrically connected to the electromagnet 70 and the switch button 72. The mounting portion 6 is provided with a battery mounting slot 62, the rechargeable battery 71 is located in the battery mounting slot 62, and the switch button 72 is located near the gripping handle.

[0058] Specifically, in the present embodiment, a gripping handle is provided for convenient use of the auxiliary bracket by hand, a rechargeable battery 71 is provided for repeated charging and use without wired connection, and is convenient for carrying and mobile use, a switch button 72 and an electromagnet 70 are provided, and the switch button 72 is pressed so that the electromagnet 70 becomes magnetic after being energized and adsorbed on the outside of the door sheet metal 3, and can also attract the wiring harness head and the iron clamp to the guide groove 21, and after the door wiring harness 8 is punched, the switch button 72 is pressed again to cut off the power to the electromagnet 70, so that the auxiliary bracket can be conveniently removed to punch the wiring harness of the next door, and the bracket body can be conveniently positioned on the outside of the door sheet metal 3, and can also assist in attracting the door wiring harness 8, and an installation slot is provided for the rechargeable battery 71, which further improves the convenience of use of the auxiliary bracket, and two electromagnets 70 are provided in the present embodiment, and in actual production and use, one or more electromagnets can also be provided as required.

[0059] Furthermore, in another embodiment, the support plate 1 and the guide part 2 can be set to metal materials. After being set to metal materials, when the electromagnet 70 is energized, the guide part 2 also has magnetism, which can attract the wiring harness head and the iron clip to the guide groove 21, and then the wiring harness head, the iron clip and the guide part 2 of the door wiring harness 8 are passed through the wiring harness installation hole 32, which is more convenient to use.

[0060] In another preferred embodiment, the magnetic attraction component is set as a magnet. In this setting, the rechargeable battery 71 and the switch button 72 are no longer provided, so the cost is also lower.

[0061] In another preferred embodiment, a first bolt hole is provided on the side of the support plate 1 close to the mounting platform 61, and a second bolt hole corresponding to the first bolt hole is provided on the mounting platform 61, and a fastening bolt is also provided, and the fastening bolt passes through the first bolt hole and the second bolt hole in sequence. It should be noted that the first bolt hole, the second bolt hole and the fastening bolt provided in this embodiment are only one of the detachable connection methods between the support plate 1 and the handheld component, and in this way, the bracket body can be simply and quickly installed on the handheld component for use, and can also be connected by other methods such as setting a buckle, a latch and other structures, which is not specifically limited in this embodiment.

[0062] In summary, the utility model discloses an auxiliary bracket for installing a door wiring harness 8, including a bracket body, a magnetic suction component and a hand-held assembly. The bracket body includes a support plate 1, and a guide portion 2 integrally arranged at one end of the support plate 1.

When the auxiliary bracket is in use, the bracket body is positioned on the outside of the door sheet metal 3 by the magnetic suction component, and the guide portion 2 is aligned with the wiring harness mounting hole 32 and Extending into the wiring harness mounting hole 32, the guide groove 21 of the guide part 2 extends in the gap of the door sheet metal 3. When the door wiring harness 8 is punched, the end portion falls into the guide groove 21 in the gap and is further guided by the guide groove 21 to the wiring harness mounting hole 32, and then passes through the wiring harness mounting hole 32. The auxiliary bracket has the advantages of simple structure and easy use, which solves the problem of inconvenient punching of the door wiring harness 8 in the door sheet metal 3, and can greatly improve the efficiency of punching the door wiring harness 8. The magnetic suction component can assist in attracting the door wiring harness 8, and the handheld component further improves the convenience of using the auxiliary bracket.

[0063] Finally, see Figure 3 to Figure 6 The use of the auxiliary bracket for installing the door wiring harness 8 disclosed in the utility model is described as follows:

[0064] When using the auxiliary bracket to install the door harness 8, first align the guide part 2 with the harness installation hole 32 on the door sheet metal 3, then extend the guide part 2 into the harness installation hole 32, and ensure that the outer walls of the guide part 2 are respectively in contact with the inner walls of the harness installation hole 32, and the outer end surface of the connecting part of the guide part 2 and the support plate 1 is in contact with the corresponding inner wall of the harness installation hole 32. The part of the guide part 2 extending into the harness installation hole 32 fills the width gap of the entire sheet metal gap 31, that is, ensure that the end of the guide part 2 extending into the harness installation hole 32 is in contact with the inner wall surface of the door sheet metal 3 on the other side of the gap, and press the switch button 72 so that the electromagnet 70 has magnetism after being energized and is adsorbed on the outside of the door sheet metal 3. At this time, an iron clip is pre-installed on the head of the harness, and the harness head with the iron clip automatically slides into the guide groove 21 in the gap due to the attraction of the magnetic suction component. After the harness head is sent to the guide groove 21, it can directly slide out under the action of gravity to realize the rapid punching function. In another use mode, when the door harness 8 needs to pass through the sheet metal gap 31 in the horizontal direction and then pass through the harness hole, the guide portion 2 can also be extended into the harness installation hole 32. In this setting mode, the support plate 1 and the guide portion 2 can also be set as metal materials. When the electromagnet 70 is energized, the guide portion 2 also has magnetism, which can attract the harness head and the iron clip to the guide groove 21 and pass through the harness installation hole 32.
