Description

Technical Field

[0001] The present application relates to the field of automobile technology, and more specifically, to a flexible electrical connection mechanism for a digital headlight. Background Art

[0002] With the development of automobile lighting technology, automobile headlights have evolved from basic vehicle lighting functions to intelligent and digital directions. Intelligent digital headlights have complex structures and functions, and require multiple wiring harnesses such as CANFD and LVDS video cables. Some automobile headlights require two lights to control each other, and the wiring harness of the lamps is complex and long. At this time, special mechanisms are needed to fix and adjust the external wiring harness of the lamps.

[0003] The external wiring harness of the headlamp is usually fixed to the lamp body with a wiring harness clip. One end of the wiring harness clip is fixed to the wiring harness by a cable tie, and the other end is fixed to the lamp body by a snap-on connection or an expansion screw.

[0004] The above-mentioned harness fixing structure can only fix the longer harness to the lamp body through the harness clamp to avoid the problem of the harness being too long and causing bumps and abnormal noises or dragging and causing the harness to break. However, when using digital headlights such as ADB (Adaptive Driving Beam) and DLP (Digital Light Projection), the lamp structure is complex and there are many connecting harnesses.

[0033] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0036] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0037] The present application provides a flexible electrical connection mechanism for a digital headlight, wherein an adjustment portion and a slide groove of a shell form a mechanism similar to a movable pulley, thereby storing excess wiring harnesses in the shell and pulling out the wiring harnesses when needed, thereby achieving flexible adjustment and satisfying the requirement that the wiring harnesses connecting two digital headlights must be long enough before assembly and can be shortened after assembly, while also avoiding the problem of the wiring harnesses being too long and causing bumps and abnormal noises or being dragged and causing the wiring harnesses to break.

[0038] Combination Figure 1 , 2 As shown in FIG. 8 , the flexible electrical connection mechanism of the digital headlight provided in the present application includes a housing 7, a cover 1, and an adjustment portion and a harness card 6 arranged in the housing 7. The adjustment portion and the harness card 6 are arranged at both ends of the inner cavity of the housing 7. The harness 2 is connected from the first end ( Figure 1 After entering the harness port 72 of the housing 7 (shown as the upper end), it bypasses the harness card 6 and the adjusting member 5 of the adjusting portion in sequence, and passes through the second end ( Figure 1 The wire harness opening 72 (shown as the lower end) extends out of the housing 7, so that the wire harness 2 forms two inflection points in the housing 7. After the wire harness is positioned on the housing 7, the cover 1 is snapped on the opening of the housing 7, and the two are detachably connected. The complete wire harness length adjustment mechanism is detachably positioned on the lamp body, and when the wire harness is pulled, the wire harness can be freely extended and retracted through the movement of the adjustment part.

[0039] Preferably, the cover 1 is provided with a plurality of water leakage holes to ensure the dryness inside the shell and increase the service life of the metal parts inside the shell.

[0040] Specifically, Figure 1 As shown, a strip-shaped slide groove 71 is provided on the inner side of the housing 7, the adjusting member 5 is slidably arranged on the slide groove 71, and the harness card 6 is fixed at the first end of the slide groove 71 ( Figure 1 On the inner side of the shell outside (shown as the lower end).

[0041] Preferably, the adjusting portion further comprises two springs 3. The second end ( Figure 1 Two first positioning posts 73 extending along the groove depth direction of the slide groove 71 are provided on the outer side of the housing 7 (shown as the upper end in FIG). The two first positioning posts 73 are symmetrically arranged relative to the slide groove 71. Figure 1 and 3 As shown, two second positioning posts 53 extending along the groove depth direction of the slide slot 71 are symmetrically provided at the end of the adjusting member 5 away from the first positioning post 73. The two ends of the spring 3 are respectively positioned on the first positioning post 73 and the second positioning post 53 by hooks.

[0042] When an external force pulls the wire harness near the adjusting member 5, the wire harness drives the adjusting member 5 to slide relative to the slide slot 71 toward the wire harness clamp 6, the spring 3 is stretched, the wire harness inside the housing 7 is shortened, and the wire harness outside the housing 7 is lengthened. When the external force is released, under the action of the rebound force of the spring 3, the adjusting member 5 slides relative to the slide slot 71 away from the wire harness clamp 6, the wire harness inside the housing 7 is lengthened, and the wire harness outside the housing 7 is shortened.

[0043] As an example, Figure 3-6As shown, the adjusting member 5 includes a body 51, a first protrusion 54 protruding toward the slide slot 71 is provided on the first end 55 (the end close to the first positioning column 73) of the body 51, and a slider 52 protruding toward the slide slot 71 is provided at the center of the second end of the body 51, and the protruding height of the slider 52 is higher than the protruding height of the first protrusion. The wire harness 2 passes through the space between the first protrusion 54 and the slider 52, and the end 522 of the first end of the slider 52 is inserted into the slide slot 71, so that the wire harness 2 is limited by the body 51 (including the first protrusion 54), the slider 52 and the slide slot 71, ensuring the positioning stability of the wire harness.

[0044] Preferably, if Figure 3 As shown, the end portion 522 of the slider 52 extending into the slide groove 71 is in a plate shape, and the other portion is in a cylindrical shape.

[0045] On this basis, preferably, Figure 3 and 4 As shown, a cushion block 4 is provided on the cylindrical portion 521 between the main body 51 and the end portion 522 of the slider 52 to support and protect the wiring harness.

[0046] Preferably, if Figure 3 and 4 As shown, the cushion block 4 is annular and is mounted on the slider 52. When the harness driving adjustment member slides relative to the slide slot, the cushion block can rotate with the relative movement between the harness and the adjustment member, thereby reducing the wear of the harness.

[0047] Preferably, if Figure 3 As shown, the first end 55 of the body 51 is V-shaped, the small end of the V-shape faces the first positioning column 73, and the outermost side of the V-shape does not interfere with the spring 3. Therefore, the end of the V-shape plays a further guiding role in the reset of the adjusting member.

[0048] Preferably, the middle portion of the V-shape has a notch 56 extending along the groove depth direction of the slide groove 71, which plays a role in reducing weight and lowering the return resistance of the adjusting member.

[0049] As an example, Figure 7 As shown, the wire harness card 6 includes a mounting portion and a clamping portion arranged on the mounting portion.

[0050] The mounting portion includes a plug connector 66 and a baffle 65 sandwiched between the plug connector 66 and the clamping portion, and the outer edge of the baffle 65 protrudes from the outer edge of the plug connector 66. When the plug connector 66 is inserted into the mounting hole on the housing 7, the baffle 65 blocks the mounting hole to prevent the mounting hole from affecting the wiring harness.

[0051] As an embodiment, the connector 66 is provided with at least one flexible anti-return plate arranged at intervals along its axial direction, and the anti-return plate is in a cone shape. During installation, the anti-return plate is pressed by external force to make it fit toward the center, and when the size is smaller than the installation hole, it is passed through the installation hole, and then the external force on the anti-return plate is released, and the anti-return plate returns to its original shape, and its size is larger than the installation hole, so that the connector cannot be removed from the installation hole, so that the wiring harness is clamped on the housing 7.

[0052] Preferably, the check plate is semi-conical in shape. The semi-conical check plate is easier to squeeze during installation, can be reduced in size to a size smaller than the inner diameter of the installation hole more quickly, and can be more easily passed through the installation hole, thereby improving installation efficiency while ensuring installation quality.

[0053] As an embodiment, the clamping portion includes a base 61 and a flexible sheet 63. The first end ( Figure 7 A plug hole is provided between the base 61 and the stopper 65 of the mounting portion, and a block 62 is provided in the middle of the base 61. The first end of the flexible sheet 63 is fixed to the second end ( Figure 7 A strip-shaped slot 64 is provided on the second end of the flexible sheet 63. Figure 1 After the second end of the flexible sheet 63 wraps around the wiring harness 2 and passes through the socket, the clamping block 62 is clamped in the strip-shaped clamping groove 64 on the second end of the flexible sheet 63, so that the flexible sheet 63 cannot escape from the socket, thereby limiting the wiring harness 2 in the annular space surrounded by the flexible sheet 63 and the base 61.

[0054] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
