Abstract
Description
Technical Field
[0001] This utility model relates to a component for fixing vehicle lights to the body sheet metal. Background Technology
[0002] The traditional methods of fixing vehicle lights to the body sheet metal mainly include the following:
[0003] 1. The headlight mounting brackets are directly fixed to the sheet metal. This method does not allow for adjustment of the mounting position and is only suitable for locations where the sheet metal tolerance is very small.
[0004] 2. The headlight mounting legs are secured with adjusting nuts. Although the deviation of the assembly plane can be compensated by adjusting the nuts, the adjustment range is limited and the installation position is restricted.
[0005] 3. The headlight mounting legs are fixed with sliding grooves. Although the sliding groove structure can be adjusted, it affects the overall strength. Utility Model Content
[0006] To address the aforementioned problems, this utility model provides a component for fixing vehicle lights to the vehicle body sheet metal, effectively solving the problems mentioned in the background art.
[0007] The technical solution adopted in this utility model is:
[0008] A component for fixing a vehicle headlight to a vehicle body sheet metal includes a metal bracket, a headlight housing mounting leg, and a vehicle body sheet metal. The metal bracket is formed by a longitudinally arranged vehicle body fixing bracket and a transversely arranged headlight fixing bracket. The vehicle body sheet metal has a first screw hole. The vehicle body fixing bracket has a longitudinally adjustable elongated hole at a position matching the first screw hole. The vehicle body fixing bracket is fixed to the vehicle body sheet metal by passing a first screw through the adjustable elongated hole and then into the first screw hole. The headlight fixing bracket has a second screw hole. The headlight housing mounting leg has a circular hole at a position matching the second screw hole, and the inner diameter of the circular hole is larger than the inner diameter of the second screw hole. The headlight housing mounting leg is fixed to the headlight fixing bracket by passing a second screw through the circular hole and then into the second screw hole.
[0009] Preferably, the first screw is adjustable in the longitudinal direction of the adjusting elongated hole.
[0010] Preferably, the second screw can be adjusted to any position within the circular hole.
[0011] Preferably, the metal bracket has an L-shaped structure, the vehicle body fixing bracket is the longitudinal part of the L-shaped structure, and the headlight fixing bracket is the transverse part of the L-shaped structure.
[0012] The innovative points of this utility model are as follows:
[0013] 1. Modular design of L-shaped metal bracket:
[0014] The metal bracket is composed of a longitudinal body fixing bracket and a transverse headlight fixing bracket, forming an L-shaped structure that separates the headlight from the body and enables modular assembly.
[0015] 2. Two-degree-of-freedom adjustment mechanism:
[0016] Body side adjustment: The body fixing bracket has a longitudinal adjustment elongated hole, which is connected to the body sheet metal through the first screw. The adjustment elongated hole allows the adjustment bracket to slide along the body height direction to compensate for the height tolerance of the sheet metal assembly surface.
[0017] Headlight side adjustment: The headlight housing mounting leg has a round hole with an inner diameter larger than the screw hole. The second screw passes through the round hole and connects to the headlight mounting bracket. The gap between the round hole and the screw forms a planar floating structure, which allows the headlight to be finely adjusted in any direction in the horizontal plane and absorbs the misalignment tolerance between the headlight body and the sheet metal.
[0018] 3. Decoupled adjustment design:
[0019] The adjustment functions of the body side (long strip hole) and the headlight side (large diameter round hole) are independent: the body side only adjusts the vertical position, while the headlight side adjusts the horizontal position. This structure avoids the strength reduction problem caused by the integration of multi-directional adjustment in the traditional sliding groove structure.
[0020] The beneficial effects of this utility model are as follows:
[0021] 1. Compatible with large size tolerances:
[0022] By adjusting both the elongated hole and the large-diameter round hole, the manufacturing tolerances of the body sheet metal and the deviation of the headlight installation position can be absorbed, reducing the dependence on the machining precision of the parts.
[0023] 2. Improve assembly flexibility and efficiency:
[0024] Precise positioning is not required during installation: the headlights can be pre-fixed with metal brackets, and then the position of the headlights in the elongated holes and round holes can be matched with the body sheet metal by adjusting the screws, which simplifies the assembly process and reduces adjustment time.
[0025] 3. Maintain structural strength:
[0026] Compared to traditional chute structures (which weaken rigidity due to grooving), this design uses local openings (adjustable elongated holes + round holes) and an L-shaped metal bracket for overall load-bearing, ensuring the reliability of the connection points against vibration and impact.
[0027] 4. Reduce costs and failure rate:
[0028] Eliminating extra parts such as adjusting nuts and using only standard screws for tightening reduces material costs;
[0029] Reduce assembly stress caused by tolerances to avoid the risk of headlight bracket cracking or sheet metal deformation.
[0030] This invention decouples the adjustment functions of the vehicle body and the headlights through an L-shaped metal bracket, and uses an adjustment elongated hole to achieve height compensation and a large-diameter circular hole to achieve planar floating. Without significantly increasing costs, it significantly improves tolerance compatibility, assembly efficiency and connection reliability, and is particularly suitable for tolerance-sensitive headlight installation scenarios.

[0042] like Figure 1-4As shown, a component for fixing a vehicle headlight to a vehicle body sheet metal includes a metal bracket 1, a headlight housing mounting leg 2, and a vehicle body sheet metal 3. The metal bracket 1 is formed by a longitudinally arranged vehicle body fixing bracket 11 and a transversely arranged headlight fixing bracket 12 fixedly combined together. The vehicle body sheet metal 3 has a first screw hole 31. The vehicle body fixing bracket 11 has a longitudinally adjustable elongated hole 13 at a position matching the first screw hole 31. The vehicle body fixing bracket 11 is fixed to the vehicle body sheet metal 3 by a first screw 14 passing through the adjustable elongated hole 13 and then into the first screw hole 31. The headlight fixing bracket 12 has a second screw hole 15. The headlight housing mounting leg 2 has a round hole 21 at a position matching the second screw hole 15, and the inner diameter of the round hole 21 is larger than the inner diameter of the second screw hole 15. The headlight housing mounting leg 2 is fixed to the headlight fixing bracket 12 by a second screw 16 passing through the round hole 21 and then into the second screw hole 15.
[0043] The first screw 14 can be adjusted longitudinally in the adjusting elongated hole 13.
[0044] The second screw 15 can be adjusted to any position within the circular hole 21.
[0045] The metal bracket 1 has an L-shaped structure, the vehicle body fixing bracket 11 is the longitudinal part of the L-shaped structure, and the headlight fixing bracket 12 is the transverse part of the L-shaped structure.
[0046] The dual-degree-of-freedom decoupling adjustment of this utility model:
[0047] The L-shaped metal bracket separates the body and headlight adjustment functions, and the adjustment of the elongated hole (body side) and the large-diameter round hole (headlight side) are used to control the tolerance compensation in different directions, so as to achieve efficient assembly and reliable fixation.
[0048] Workflow and mechanism breakdown:
[0049] 1. Fixing the body sheet metal to the metal bracket (height adjustment):
[0050] Component interaction:
[0051] The first screw hole is pre-set in the body sheet metal (standard position);
[0052] The metal bracket's body mounting bracket (longitudinal section) has longitudinal adjustment slots.
[0053] Regulation mechanism:
[0054] Pass the first screw through the adjustment slot and screw it into the screw hole on the body panel (not fully tightened).
[0055] The adjustable elongated hole allows the metal bracket to slide vertically, compensating for height tolerances during the manufacturing of the body sheet metal;
[0056] Locking method:
[0057] After adjusting the position, tighten the first screw to fix the metal bracket to the body sheet metal;
[0058] Advantages: Only unidirectional (Z-axis) adjustment is required, avoiding the structural strength loss of multi-directional grooves.
[0059] 2. Fixing the headlights to the metal bracket (fine-tuning the horizontal alignment):
[0060] Component interaction:
[0061] The metal bracket for fixing the headlights (horizontal part) has a pre-set second screw hole (precise position).
[0062] The lamp housing mounting legs of the vehicle headlight have large-diameter round holes (hole diameter > diameter of the second screw hole);
[0063] Regulation mechanism:
[0064] Pass the second screw through the round hole on the lamp housing mounting leg and screw it into the second screw hole of the metal bracket;
[0065] The gap between the round hole and the second screw allows the lamp housing mounting leg to move freely in the horizontal plane (XY plane), compensating for the misalignment tolerance between the headlight and the body sheet metal;
[0066] Locking method: After adjustment, tighten the second screw to press the lamp housing mounting leg against the screw head;
[0067] Advantages: The planar floating design absorbs multi-directional deviations, eliminating the need for additional adjusting nuts.
[0068] 3. The core value of decoupling and adjustment:
[0069] Vehicle side (adjusting elongated hole) → Only control the vertical position (Z-axis);
[0070] Headlight side (large diameter round hole) → Only controls the horizontal position (XY plane);
[0071] Decoupling effect: The two adjustments do not interfere with each other, avoiding the strength reduction caused by the integrated multi-directional adjustment of traditional slides (excessive slot length weakens rigidity).
[0072] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
