Description

Technical Field

[0001] This invention relates to the field of vehicle structure technology, and in particular to a headlight connection structure and a vehicle having the same. Background Technology

[0002] As car buyers place increasingly higher demands on the aesthetics of their vehicles, the requirements for the gap and surface finish (DTS) between the headlights and the front bumper are also becoming more stringent. Therefore, during structural design, it's often desirable to incorporate an interlocking mechanism between the headlight lenses and the front bumper to define their positions. However, when driving on rough mountain roads, the front bumper tends to move up and down, potentially causing damage to the headlight lenses and leaks. Without this interlocking mechanism, the required DTS between the headlights and the front bumper bracket cannot be met. Summary of the Invention

[0003] One objective of the first aspect of this invention is to provide a vehicle headlight connection structure that can prevent headlight damage caused by bumper creep while ensuring aesthetic appearance.

[0004] A further objective of this invention is to simplify the structure and reduce costs.

[0005] A further objective of this invention is to reduce the difficulty of assembling headlights and bumpers.

[0006] A second aspect of the present invention aims to provide a vehicle including a headlight connection structure that can avoid headlight damage caused by bumper creep while ensuring aesthetic appearance.

[0007] Specifically, the present invention provides a vehicle lamp connection structure, comprising:

[0008] The headlights are fixed to the vehicle body; and

[0009] The bumper, directly or indirectly, forms a positioning fit with the headlights through an anti-creep bracket fixed to the vehicle body, forming a first preset gap. The first preset gap is determined based on the driving creep displacement of the bumper and related part tolerances and assembly tolerances, and is used to ensure the appearance quality requirements between the headlights and the bumper and to prevent the headlights from being damaged by the creep of the bumper.

[0010] Optionally, the anti-creep bracket is fixed to the bumper and connected to the vehicle light via a positioning structure.

[0011] Optionally, the bumper includes a bumper skin and a bumper reinforcement bracket that are fixedly connected. The bumper reinforcement bracket is provided with an anti-creep positioning pin and an anti-creep positioning hole. There is a first preset gap between the anti-creep positioning pin and the anti-creep positioning hole.

[0012] Optionally, the anti-creep positioning pin and the anti-creep positioning hole have the first preset gap in the lateral and vertical directions of the vehicle.

[0013] Optionally, the anti-creep positioning pin is integrally formed with the bumper reinforcement bracket.

[0014] Optionally, the anti-creep bracket is provided with a first positioning hole and a second positioning hole, and the vehicle light is provided with a first positioning pin and a second positioning pin that respectively cooperate with the first positioning hole and the second positioning hole.

[0015] Optionally, the first positioning hole and the second positioning hole are a round hole and an elliptical hole, respectively. The first positioning hole and the first positioning pin have a second preset gap in the horizontal and vertical directions of the vehicle, and the second positioning hole and the second positioning pin have a third preset gap in the vertical direction of the vehicle.

[0016] Optionally, the anti-creep bracket is made of plastic or aluminum.

[0017] Optionally, a pin hole fits between the headlight and the bumper to form the first preset gap.

[0018] In particular, the present invention also provides a vehicle including the headlight connection structure described in any of the above claims.

[0019] According to one embodiment of the present invention, the headlight connection structure establishes a positioning fit between the headlight and the bumper with a first preset gap. The headlight is fixed to the vehicle body structure. The first preset gap is determined based on the bumper's creep displacement during vehicle operation and the relevant tolerances between the headlight and the bumper. While ensuring that the DTS (Displacement Tolerance System) requirements between the headlight and the bumper are met, this design prevents the positioning component between the bumper and the headlight from being broken due to bumper creep during vehicle operation, thus avoiding headlight damage and water leakage at the headlight location. In other words, the headlight connection structure of this embodiment ensures aesthetic appearance while preventing headlight damage caused by bumper creep.

[0020] According to one embodiment of the present invention, the headlight and the bumper are directly fitted with pin holes. This positioning method has a simple structure, few parts, and therefore low cost.

[0021] According to one embodiment of the present invention, the anti-creep positioning pin and the bumper reinforcement bracket are integrally formed. The integral bumper reinforcement bracket and the anti-creep positioning pin can better control the relative position between the two, avoid dimensional deviations during assembly, and facilitate control of the relative position between the anti-creep positioning pin and the anti-creep positioning hole.

Detailed Implementation

[0032] Figure 1 This is a schematic diagram of the assembly structure of the headlight connection structure 100 (bumper 20 omitted) and the body 200 according to an embodiment of the present invention. Figure 2 This is a schematic diagram of a vehicle lamp connection structure 100 (vehicle lamp 10 is hidden) according to an embodiment of the present invention. Figure 3 This is a schematic diagram of a vehicle lamp connection structure 100 according to another embodiment of the present invention. Figure 1 As shown, in one embodiment, the headlight connection structure 100 includes a headlight 10 and a bumper 20 (see...). Figure 2 or Figure 3 The headlight 10 is fixed to the vehicle body at a position 200 mm, for example... Figure 1 As shown, the headlight 10 is connected to the body 200 via a headlight bracket 201. The headlight bracket 201 can be connected to both the headlight 10 and the body 200 via fasteners. The bumper 20 forms a positioning fit with the headlight 10 with a first preset gap directly or indirectly through an anti-creep bracket 30 fixed to the body 200. The first preset gap is determined based on the creep displacement of the bumper 20 during driving and related part tolerances and assembly tolerances, and is used to ensure the appearance quality requirements between the headlight 10 and the bumper 20 and to prevent damage to the headlight 10 caused by the creep of the bumper 20. Figure 2 As shown, in one embodiment, the headlight connection structure 100 further includes an anti-creep bracket 30, which has an anti-creep positioning hole 301. An anti-creep positioning pin 221 is provided at the bumper 20, and a first preset gap exists between the anti-creep positioning pin 221 and the anti-creep positioning hole 301. The anti-creep bracket 30 is fixed to the vehicle body 200 nearby, for example, to the bumper 40 (see...). Figure 2 Furthermore, the anti-creep bracket 30 is also connected to the headlight 10 via a positioning structure, such as a pin-and-hole positioning structure, thereby enabling the bumper 20 and the headlight 10 to form a positioning fit with a first preset gap. In another embodiment, such as... Figure 3 As shown, a pin hole fits between the headlight 10 and the bumper 20 to form a first preset gap, i.e. Figure 3 As shown, the headlight 10 is provided with an anti-creep positioning hole 301, and the bumper 20 is provided with an anti-creep positioning pin 221. Of course, in the above embodiment, the main components for the anti-creep positioning hole 301 and the anti-creep positioning pin 221 can be reversed, for example, with... Figure 2 Taking the illustrated embodiment as an example, the anti-creep positioning hole 301 can be set at the bumper 20, and the anti-creep positioning pin 221 can be set on the anti-creep bracket 30, which can also achieve the same effect. Figure 3The same applies to other embodiments, and will not be repeated here. It should be noted that the setting of the first preset gap here needs to consider two factors. One is the creep displacement of the bumper 20 during driving. This creep displacement can be obtained from experimental data or calculated from simulation. The other factor is tolerance, namely the dimensional tolerance and assembly tolerance of the relevant components that affect the phase position between the headlight 10 and the bumper 20. The gap value that can ensure the smooth assembly between the headlight 10 and the bumper 20 is obtained through dimensional chain calculation. At the same time, the DTS requirements between the headlight 10 and the bumper 20 should be guaranteed as much as possible, so that each component can be smoothly assembled and meet the DTS requirements between the headlight 10 and the bumper 20.

[0033] In this embodiment, the headlight connection structure 100 establishes a positioning fit between the headlight 10 and the bumper 20 with a first preset gap. The headlight 10 is fixed to the vehicle body 200 structure. The first preset gap is determined based on the creep displacement of the bumper 20 during driving and the relevant tolerances between the headlight 10 and the bumper 20. While ensuring that the DTS (Displacement Tolerance System) requirements between the headlight 10 and the bumper 20 are met, this structure prevents the positioning component between the bumper 20 and the headlight 10 from being broken due to the creep of the bumper 20 during vehicle operation, thus avoiding damage to the headlight 10 and water leakage at the headlight 10. In other words, the headlight connection structure 100 of this embodiment ensures aesthetic appearance while preventing damage to the headlight 10 caused by the creep of the bumper 20.

[0034] Furthermore, the direct pin-hole mating of the headlight 10 and bumper 20 results in a simple structure with fewer parts, thus lowering the cost. However, due to the accumulated tolerances of the body 200, the assembly of the anti-creep positioning pin 221 with the anti-creep positioning hole 301 on the headlight 10 may be somewhat difficult. Connecting the headlight 10 and bumper 20 using the anti-creep bracket 30 ensures smooth assembly and reduces assembly difficulty.

[0035] In one embodiment, the anti-creep bracket 30 is made of plastic or aluminum. The lightweight nature of the anti-creep bracket 30, made of plastic or aluminum, allows it to meet the requirements for positioning connections.

[0036] Figure 4 This is a schematic diagram of the anti-creep mechanism of a vehicle headlight connection structure 100 according to an embodiment of the present invention. Figure 4As shown, the anti-creep bracket 30 has a boss 31 that protrudes towards the front of the vehicle. The top of the boss 31 has an anti-creep positioning hole 301. In one embodiment, the anti-creep positioning hole 301 can be a rectangular hole, and the anti-creep positioning pin 221 can be correspondingly configured to match the shape of the rectangular hole. In another embodiment, the anti-creep positioning pin 221 can be configured with a cross-section that gradually decreases from the root to the end to facilitate insertion into the anti-creep positioning hole 301. The anti-creep positioning pin 221 is formed to match the shape of the anti-creep positioning hole 301. In this embodiment, the anti-creep positioning pin 221 and the anti-creep positioning hole 301 have a first preset gap in the lateral and vertical directions of the vehicle. Optionally, the first preset gap is set to 0.5mm, meaning that the anti-creep positioning pin 221 has a 0.5mm gap on each of the vertical sides of the vehicle and a 0.5mm gap on each of the lateral sides of the vehicle.

[0037] Figure 5 This is a front view schematic diagram of a vehicle headlight connection structure 100 (bumper 20 omitted) according to an embodiment of the present invention. In a further embodiment, the bottom of the anti-creep bracket 30 may be provided with multiple mounting holes 304 for fasteners to pass through, so as to fix it to the bumper 40 by multiple fasteners, such as... Figure 5 As shown, the bottom of the anti-creep bracket 30 can be fixedly connected to the anti-collision bar 40 with three M6 bolts.

[0038] In one embodiment, such as Figure 5 As shown, the anti-creep bracket 30 is also provided with a first positioning hole 302 and a second positioning hole 303, for example, located on the top of the anti-creep bracket 30. The vehicle lamp 10 is provided with a first positioning pin 101 and a second positioning pin 102 that respectively cooperate with the first positioning hole 302 and the second positioning hole 303 to realize the positioning connection between the anti-creep bracket 30 and the vehicle lamp 10. In a further embodiment, the first positioning hole 302 and the second positioning hole 303 are respectively a circular hole and an elliptical hole, serving as the main and auxiliary positioning holes respectively. There is a second preset gap between the first positioning hole 302 and the first positioning pin 101 in the horizontal and vertical directions of the vehicle. The second preset gap can be 0.1mm, that is, the upper and lower sides and the left and right sides of the first positioning pin 101 are respectively left with a gap of 0.1mm from the first positioning hole 302. There is a third preset gap between the second positioning hole 303 and the second positioning pin 102 in the vertical direction of the vehicle. The third preset gap can also be 0.1mm, that is, the upper and lower sides of the second positioning pin 102 are respectively left with a gap of 0.1mm from the second positioning hole 303, so that the anti-creep bracket 30 and the headlight 10 are precisely positioned.

[0039] During assembly, the anti-creep bracket 30 can be precisely positioned at the headlight 10, and then the anti-creep bracket 30 can be fastened to the bumper 40 using fasteners.

[0040] Figure 6 This is a schematic diagram of the bumper reinforcement bracket 22 of the headlight connection structure 100 according to an embodiment of the present invention. In one embodiment, as... Figure 1 As shown, the bumper 20 includes a bumper skin 21 and a bumper reinforcement bracket 22 that are fixedly connected. The bumper reinforcement bracket 22 can be connected to the bumper skin 21 by screws and ultrasonic welding. Figure 6 As shown, the anti-creep positioning pin 221 is installed on the bumper reinforcement bracket 22, that is, the anti-creep positioning pin 221 is installed on the side of the bumper reinforcement bracket 22 facing the rear of the vehicle.

[0041] In one embodiment, the anti-creep positioning pin 221 and the bumper reinforcement bracket 22 are integrally molded, using a one-piece design, and are manufactured as a whole in the mold cavity. Both the anti-creep positioning pin 221 and the bumper reinforcement bracket 22 can be made of plastic and formed by injection molding.

[0042] In this embodiment, the integrated bumper reinforcement bracket 22 and anti-creep positioning pin 221 can better control the relative position between them, avoid dimensional deviations during assembly, and facilitate control of the relative position between the anti-creep positioning pin 221 and the anti-creep positioning hole 301.

[0043] In the above embodiment, the rear side of the bumper skin 21 is fixedly connected to the bumper reinforcement bracket 22. The rear side of the bumper reinforcement bracket 22 is provided with an anti-creep positioning pin 221, which is used to position and connect to an anti-creep bracket 30 located behind the bumper 20 bracket. The rear side of the anti-creep bracket 30 is connected to the headlight 10 and the bumper 40. The headlight 10 can be a headlight, the bumper 20 can be the front bumper 20 of a vehicle, and the bumper 40 is a front bumper 40. Figure 6 As shown, since there are two headlights at the front of the vehicle, two anti-creep brackets 30 can be installed at both ends of the rear side of the bumper reinforcement bracket 22.

[0044] The present invention provides a vehicle including the headlight connection structure 100 of any of the above embodiments or combinations thereof.

[0045] In this embodiment, the vehicle has a positioning fit between the headlight 10 and the bumper 20 with a first preset gap. The headlight 10 is fixed to the vehicle body 200 structure. The first preset gap is determined based on the creep displacement of the bumper 20 during driving and the relevant tolerances between the headlight 10 and the bumper 20. While ensuring that the DTS requirements between the headlight 10 and the bumper 20 are met, this design avoids the breaking of the positioning component between the bumper 20 and the headlight 10 due to the creep of the bumper 20 during vehicle operation, thus preventing damage to the headlight 10 and water leakage at the headlight 10. In other words, the headlight connection structure 100 of this embodiment ensures aesthetic appearance while preventing damage to the headlight 10 caused by the creep of the bumper 20.

[0046] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
