Technical Field
[0001] This utility model relates to the field of automotive technology, specifically to a front through-light bumper assembly and a vehicle. Background Technology
[0002] With the development of technology, more and more cars are equipped with front continuous lights. The front continuous lights extend along the width of the car, which not only increases the visual width of the vehicle, but also brings a more modern and high-tech appearance to the vehicle.
[0003] In related technologies, the front through light is usually connected to the body frame. The front through light is an exterior component, while the body frame is a structural component. The front through light needs to be assembled on the final assembly line. Furthermore, the front through light and the body frame have cross-system positioning, which leads to poor assembly accuracy, many fixing points in the final assembly process, and a long assembly cycle.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A front through-light bumper assembly includes: a front bumper having a through hole; a first bracket fixed to the inner side of the front bumper; a front through-light connected to the first bracket, with a portion of the front through-light located in the through hole; and a second bracket disposed on the rear side of the front through-light, the second bracket being fixed to the front through-light and the first bracket.
[0007] According to the above-mentioned technical means, during assembly, the first bracket is first fixed to the front bumper to form the first sub-assembly; then the front through-light is fixed to the first bracket to form the second sub-assembly; then the second bracket is fixed to the first bracket of the first sub-assembly, and at the same time, the second bracket is fixed to the front through-light of the second sub-assembly, thus forming a modular front through-light bumper assembly. By fixing the front through-light to the front bumper through the first and second brackets, it is not necessary to connect the front through-light to the vehicle frame, thus eliminating the need to fix the front through-light to the vehicle frame on the final assembly line, reducing the final assembly cycle time by approximately 10-20 seconds, improving assembly efficiency, and effectively solving the problem of long assembly cycles caused by connecting the front through-light to the vehicle frame in existing technologies.
[0008] Furthermore, the front bumper and the first bracket are welded together.
[0009] According to the above-mentioned technical means, welding can make the front bumper and the first bracket form a whole structure, providing higher structural integrity and more effectively protecting the safety of passengers in the vehicle when the vehicle is hit; and, it does not require the use of screws, springs and other fixing parts, saving material costs.
[0010] Furthermore, both the front bumper and the first bracket are made of plastic.
[0011] Based on the aforementioned technical means, plastic materials are generally much lighter than metals.

[0013] Based on the aforementioned technical means, when the front through-light and the first bracket are connected, since there is no need to use fasteners such as screws and nuts, nor is it necessary to perform welding or bonding operations, rapid installation can be achieved, which can significantly reduce the time required for assembly, thereby improving production efficiency; and the reduction of the need for additional fasteners and the simplification of the installation process help to reduce production costs.
[0014] Furthermore, one of the first bracket and the front through light is provided with a buckle, and the other of the first bracket and the front through light is provided with a locking hole, and the buckle engages with the locking hole.
[0015] According to the above-mentioned technical means, during installation, the buckle and the hole are aligned, and then the front through light is pressed to fix the front through light onto the first bracket. The operation is simple and quick, improving assembly efficiency. In addition, the buckle and the hole can fix the front through light to the first bracket.
[0016] Furthermore, the second bracket is connected to the front through-light and the first bracket via fasteners.
[0017] Based on the aforementioned technical methods, fasteners such as screws can provide high-strength connections, ensuring tight fixation between components. Fasteners also facilitate the adjustment of the position and angle between the second bracket and the second sub-assembly. When repair or replacement of a component is required, the fastener connection method makes disassembly simple and quick.
[0018] Furthermore, a first positioning structure is provided between the first bracket and the front bumper, the first positioning structure being used to position the relative position between the first bracket and the front bumper.
[0019] Based on the above technical means, the first positioning structure positions the first bracket and the front bumper during the welding process, thereby ensuring the positional accuracy of the first bracket after welding.
[0020] Furthermore, a second positioning structure is provided between the front through light and the first bracket, which is used to position the relative position between the front through light and the first bracket.
[0021] Based on the aforementioned technical means, the second positioning structure positions the front through light and the first bracket when they are connected, ensuring the appearance accuracy of the front through light and the front bumper.
[0022] Furthermore, the second support is made of plastic.
[0023] Based on the aforementioned technical means, plastic materials are generally much lighter than metals. Using plastic to manufacture the second bracket helps reduce the overall vehicle weight, thereby improving fuel efficiency or increasing driving range. Furthermore, plastics offer greater design freedom, making it easier to achieve complex shapes and aerodynamic optimization designs. This not only helps to enhance the vehicle's aesthetics but also improves the vehicle's aerodynamic performance, thereby further improving energy efficiency.

Figures 1 to 4 As shown, the front through light bumper assembly includes: a front bumper 1, a first bracket 2, a front through light 3, and a second bracket 4. The front bumper 1 has a through hole 101; the first bracket 2 is fixed to the inner side of the front bumper 1; the front through light 3 is connected to the first bracket 2, and a portion of the front through light 3 is located in the through hole 101; the second bracket 4 is disposed on the rear side of the front through light 3, and the second bracket 4 is fixed to the front through light 3 and the first bracket 2.
[0035] Using the technical solution of this embodiment, during assembly, the first bracket 2 is first fixed to the front bumper 1 to form a first sub-assembly; then the front through-beam 3 is fixed to the first bracket 2 to form a second sub-assembly; then the second bracket 4 is fixed to the first bracket 2 of the first sub-assembly, and simultaneously fixed to the front through-beam 3 of the second sub-assembly, thereby forming a modular front through-beam bumper assembly. By fixing the front through-beam 3 to the front bumper 1 via the first bracket 2 and the second bracket 4, it is not necessary to connect the front through-beam 3 to the vehicle frame, thus eliminating the need to fix the front through-beam 3 to the vehicle frame on the final assembly line, reducing the final assembly cycle time by approximately 10-20 seconds, improving assembly efficiency, and effectively solving the problem of long assembly cycles caused by connecting the front through-beam 3 to the vehicle frame in the prior art.
[0036] In this embodiment, the front bumper 1 and the first bracket 2 are welded together. Welding enables the front bumper 1 and the first bracket 2 to form an integral structure, providing higher structural integrity. When the vehicle is involved in a collision, it can more effectively protect the safety of passengers inside the vehicle. Furthermore, it eliminates the need for fixing parts such as screws and springs, saving material costs.
[0037] It is understood that in other embodiments, the front bumper 1 and the first bracket 2 may also be connected by fasteners such as screws.
[0038] In this embodiment, both the front bumper 1 and the first bracket 2 are made of plastic. Plastic materials are generally much lighter than metals. Using plastic to manufacture the front bumper 1 and the first bracket 2 helps reduce the overall vehicle weight, thereby improving fuel efficiency or increasing driving range. Furthermore, plastic offers greater design freedom, making it easier to achieve complex shapes and aerodynamic optimization designs. This not only helps improve the vehicle's aesthetics but also improves its aerodynamic performance, thereby further enhancing energy efficiency.
