Description

Technical Field

[0001] This invention relates to the field of automotive bumper technology, specifically to an automotive bumper with an adjustable light trough structure and its installation method. Background Technology

[0002] A car bumper is a safety and decorative component installed at the front and rear of a vehicle, consisting of a crossbeam, energy-absorbing structure, and outer covering. In the event of a low-speed collision, it can absorb energy through its own deformation to protect the main body of the vehicle. In daily use, it blends into the vehicle's design and serves a decorative purpose. With the development of technology, modern bumpers, in addition to fulfilling basic protective functions, also integrate components such as headlights and sensors, and place greater emphasis on pedestrian protection and lightweight design.

[0003] Existing car bumpers typically have fixed mounting positions for lights. This fixed structure has the following drawbacks: First, the mounting position of the lights cannot be adjusted laterally according to actual usage needs, nor can it flexibly adapt to different configurations of lights. Second, the beam angle of the lights is usually fixed and cannot provide auxiliary lighting for cornering in situations such as low-speed turning, resulting in blind spots and affecting driving safety. Summary of the Invention

[0004] The purpose of this invention is to provide a car bumper with an adjustable lamp slot structure and its installation method. By setting a connecting block that can slide along the mounting roller and a mounting frame that can rotate around the connecting shaft, the dual functions of adjusting the lateral position of the lamp on the bumper and preset illumination angle are realized, eliminating the need for temporary adjustments during driving. On the other hand, by setting multiple independent mounting frames on the mounting roller, modular installation and independent adjustment of multiple lamps are realized. Each mounting frame can install lamps with different functions, and the angle can be independently adjusted and locked according to the preset illumination direction of each lamp during installation. In use, the lamp at the corresponding angle can be directly lit according to driving needs, which simplifies operation and improves the reliability and response speed of the system, solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a car bumper with an adjustable lamp slot structure, comprising a housing, wherein a reserved slot is provided inside the housing, and mounting rollers are provided at both the upper and lower ends of the reserved slot, and at least one mounting frame is provided between the two mounting rollers, wherein a car lamp is installed inside the mounting frame, and connecting pieces are rotatably provided at both the upper and lower ends of the mounting frame via connecting shafts, wherein the connecting pieces are slidably mounted on the outside of the mounting rollers via connecting blocks having movable rails, and the connecting blocks slide along the mounting rollers and, in conjunction with the mounting frame rotating about the connecting shaft, can adjust the angle and position of the lamp inside the mounting frame.

[0006] Preferably, the mounting roller is provided with a plurality of mounting grooves evenly distributed along its length, the inner wall of the connecting block is provided with a second locking block that is connected to the mounting groove, and the upper end of the movable rail is provided with a first locking block. The connecting block that slides along the mounting roller can be locked by the first locking block and the second locking block.

[0007] Preferably, a second fixing rod is rotatably provided at the upper end of the first locking block, the second fixing rod passes through the connecting block upward, and the second fixing rod is threadedly engaged with the through-hole of the connecting block.

[0008] Preferably, the mounting roller is welded and fixed to the housing by a reinforcing plate, and the side of the connecting block has an opening for avoiding the reinforcing plate. The opening passes through the connecting block and is connected to the movable rail.

[0009] Preferably, the connecting piece has a plurality of first fixing holes arranged in a circumferential array around the axis of the connecting shaft, and the upper end of the connecting shaft extends laterally to form an extension block, the extension block being fixed relative to the connecting piece by a third fixing rod passing through one of the first fixing holes.

[0010] Preferably, the mounting roller has an arcuate profile that conforms to the inner wall of the housing.

[0011] Preferably, the two mounting rollers are welded together by a first connecting arm. The first connecting arm has a hinge hole in the middle that extends through its thickness direction. A second connecting arm is fixedly connected to the housing. The second connecting arm passes through the hinge hole and supports the first connecting arm, so that the first connecting arm and the two mounting rollers can pivot relative to the housing around the axis of the hinge hole to adjust their angle.

[0012] Preferably, the second connecting arm has a fixing plate at one end passing through the hinge hole. The fixing plate has a plurality of second fixing holes arranged in a circular array around the axis of the hinge hole. The first connecting arm has a plurality of third fixing holes arranged in a circular array around the axis of the hinge hole. A first fixing rod is provided through one of the corresponding second fixing holes and one of the third fixing holes, and the relative angle between the first connecting arm and the second connecting arm is locked by the first fixing rod.

[0013] A method for installing a car bumper with an adjustable light recess structure includes the following steps: Step 1: Install the light fixture inside the mounting frame. The connecting block drives the mounting frame to slide onto the mounting roller, and the mounting roller enters the movable rail position. Step 2: After the mounting frame reaches the required position, apply force to the connecting block in the direction of the mounting roller, so that the second locking block is embedded in the mounting groove, temporarily locking the position of the connecting block. Step 3: Rotate the second fixing rod. Through its threaded engagement with the connecting block, the first locking block slides longitudinally downward within the movable rail due to the constraint of the connecting block. The arc surface on the side of the first locking block contacts the outer wall of the mounting roller, ultimately locking the position of the connecting block. Step 4: Rotate the mounting frame around the axis of the connecting shaft with the connecting shaft as the center. Based on Step 3, adjust the angle of the mounting frame. After the angle is adjusted, the third fixing rod passes through the extension block and is embedded in the first fixing hole, finally locking the position of the mounting frame.

[0014] Preferably, the following steps are also included: Step 5: When the mounting roller has a first connecting arm and a second connecting arm, the first connecting arm rotates around the hinge hole with the support of the second connecting arm, thereby further fine-tuning the tilt angle of the mounting roller and the mounting frame. Step Six: The first fixing rod passes through the second and third fixing holes one by one to complete the final fixing of the tilt angle of the first connecting arm and the mounting frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves the dual functions of adjusting the lateral position of the lamp on the bumper and presetting the illumination angle by setting a connecting block that can slide along the mounting roller and a mounting frame that can rotate around the connecting shaft. On the one hand, the lateral sliding adjustment can compensate for the manufacturing tolerances of the bumper and the body during assembly or maintenance, making the lamp more compatible with the body lines and improving assembly quality and appearance consistency. On the other hand, the mounting frame can be pre-adjusted and locked with the illumination angle according to the preset lighting requirements during installation. When in use, the lamp at the corresponding angle can be directly lit to obtain the required lighting direction without the need for temporary adjustment during driving. The structure is more reliable and the operation is simpler.

[0016] 2. This invention uses the mounting groove on the mounting roller to engage with the second locking block on the inner wall of the connecting block, and the first locking block to press against the outer wall of the mounting roller, forming a double locking structure of engagement and friction. The second locking block is embedded in the mounting groove to achieve initial positioning and anti-slip, and the first locking block is driven to press down by the second fixing rod, and the arc surface is pressed against the outer wall of the mounting roller to generate friction. The synergistic effect can ensure that the connecting block maintains a stable position under vehicle vibration and impact environment, avoids loosening or displacement, and improves the reliability after adjustment.

[0017] 3. By setting multiple independent mounting frames on the mounting roller, modular installation and independent adjustment of multiple lamps are achieved. Each mounting frame can install lamps with different functions, and the angle can be independently adjusted and locked according to the preset lighting direction of each lamp during installation. When in use, the lamp at the corresponding angle can be lit directly according to driving needs to obtain multiple lighting modes such as low beam, high beam, and cornering assist. No mechanical adjustment is required during driving, which simplifies operation and improves the reliability and response speed of the system. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] Example 1, as Figure 1 and Figure 2 As shown, a car bumper with an adjustable lamp slot structure in this embodiment includes a housing 1. Both sides of the housing 1 are provided with reserved slots 2 for lamp installation and exposure. The interior of each reserved slot 2 is provided with a mounting frame 3 for lamp installation and fixing.

[0022] For the installation of the mounting frame 3, strip-shaped mounting rollers 4 are provided at the upper and lower ends of the reserved groove 2. The mounting rollers 4 have a certain curvature, and the curvature of the mounting rollers 4 is adapted to the curvature of the housing 1, so that the lamps inside the mounting frame 3 can fit the car bumper. A connecting piece 7 is provided at the upper end of the mounting frame 3, and a connecting block 6 is provided facing the mounting roller 4. The mounting frame 3 can be installed on the upper end of the mounting roller 4 through the connecting piece 7 and the connecting block 6.

[0023] In practical applications, multiple mounting frames 3 can be set on the same set of mounting rollers 4 as needed. Each mounting frame 3 is independently slidably mounted on the mounting roller 4 through its own connecting block 6, and its angle can be independently adjusted by rotating through the connecting shaft 8. Different functional lamps can be installed in each mounting frame 3. During installation, the angle of each lamp is adjusted and locked according to the preset lighting direction of each lamp. When in use, the lamp at the corresponding angle is lit according to the driving needs to obtain the required lighting effect without the need for mechanical adjustment during driving.

[0024] The upper end of the mounting frame 3 is rotatably connected to the connecting piece 7 via a connecting shaft 8. The mounting frame 3 can be rotated within the connecting piece 7 with the connecting shaft 8 as the center to adjust the angle of the mounting frame 3 and the lamps inside the mounting frame 3.

[0025] Connecting block 6 and connecting piece 7 are preferably integrally molded structures, such as Figure 3 , Figure 4 and Figure 5 As shown, the connecting block 6 is a housing with a movable rail 12. The two mounting rollers 4 can be slidably installed inside the movable rail 12 to complete the temporary suspension, which is convenient for subsequent fixing.

[0026] In order to ensure that the mounting roller 4 can be fixed to the housing 1 and to prevent the mounting roller 4 from being suspended in the air, the mounting roller 4 and the housing 1 are welded and fixed together by strip-shaped reinforcing plates 5. The side of the connecting block 6 is provided with an opening 25 to avoid the reinforcing plates 5, so that the connecting block 6 can be slidably inserted from one end of the mounting roller 4. This structure makes the installation and position adjustment of the mounting frame 3 easier.

[0027] After the mounting frame 3 is adjusted along the mounting roller 4, when it is necessary to lock the connection between the connecting block 6 and the mounting roller 4, a number of mounting grooves 14 are evenly arranged on the mounting roller 4 along its length direction, which can provide different installation positions. The inner wall of the connecting block 6 is provided with a second locking block 13 that matches the mounting groove 14. The size of the movable rail 12 is such that the mounting roller 4 and the second locking block 13 are distributed one by one. When the connecting block 6 is initially inserted into the outside of the mounting roller 4, the second locking block 13 does not need to be inserted into and contact the inside of the mounting groove 14. When it is necessary to fix the connecting block 6 and the corresponding mounting frame 3, the horizontal sliding of the connecting block 6 can make the second locking block 13 embed into the corresponding mounting groove 14, thus completing the initial fixation of the connecting block 6.

[0028] After initial fixing, the position of the connecting block 6 needs to be completely locked. The first locking block 11 at the upper end of the movable rail 12 moves longitudinally downward after the second fixing rod 22 rotates. The side of the first locking block 11 facing the mounting roller 4 is provided with an arc surface 15, which can be adapted to the outer wall of the mounting roller 4. After the first locking block 11 is pressed down, the arc surface 15 contacts the outer wall of the mounting roller 4. The pressing of the first locking block 11, combined with the cooperation of the mounting groove 14 and the second locking block 13, can lock the position of the connecting block 6.

[0029] The second fixing rod 22 passes through the connecting block 6 upwards and is threaded into the through-hole of the connecting block 6. The first locking block 11 is rotatably connected to one end of the second fixing rod 22. The rotation of the second fixing rod 22 can adjust the first locking block 11 longitudinally and adjust whether the connecting block 6 is finally locked.

[0030] In order to lock the rotation angle after the mounting frame 3 rotates around the connecting shaft 8, an extension block 9 is provided on one side of the upper end of the connecting shaft 8. A third fixing rod 23 is provided through the inside of the extension block 9. The first fixing holes 10 are evenly distributed around the connecting shaft 8. After the third fixing rod 23 passes through the extension block 9 and the first fixing holes 10 one by one, the angle of the mounting frame 3 is fixed.

[0031] In this embodiment, a method for installing a car bumper with an adjustable light trough structure includes the following steps: Step 1: Install the lamp inside the mounting frame 3. The connecting block 6 drives the mounting frame 3 to slide onto the mounting roller 4. The mounting roller 4 enters the position of the movable rail 12. Step 2: After the mounting frame 3 reaches the required position, apply force to the connecting block 6 in the direction of the mounting roller 4, so that the second locking block 13 is embedded in the mounting groove 14, temporarily locking the position of the connecting block 6. Step 3: Rotate the second fixing rod 22. Through its threaded engagement with the connecting block 6, the first locking block 11 slides longitudinally downward within the movable rail 12 due to the restriction of the connecting block 6. The arc surface 15 on the side of the first locking block 11 contacts the outer wall of the mounting roller 4, finally locking the position of the connecting block 6. Step 4: Rotate the mounting frame 3 around the axis of the connecting shaft 8 with the connecting shaft 8 as the center. Based on Step 3, adjust the angle of the mounting frame 3. After the angle is adjusted, the third fixing rod 23 passes through the extension block 9 and is embedded in the first fixing hole 10, finally locking the position of the mounting frame 3.

[0032] Example 2, as Figure 6 , 7 As shown in Figure 8, this embodiment of the car bumper with an adjustable light groove structure is basically the same as the structure of embodiment 1, except that the reinforcing piece 5 that is welded and fixed between the housing 1 and the mounting roller 4 is omitted.

[0033] Instead, one end of each of the two mounting rollers 4 is welded and fixed by a first connecting arm 16. A hinge hole 24 is provided through the middle of the first connecting arm 16. A second connecting arm 17 is welded to the housing 1. The second connecting arm 17 passes through the hinge hole 24 and supports the first connecting arm 16. The first connecting arm 16 can drive the mounting rollers 4 and the mounting frame 3 hanging on the mounting rollers 4 to adjust and change their angles.

[0034] After the angle changes, in order to fix the angle change of the mounting roller 4, a fixing plate 19 is provided at one end of the second connecting arm 17 that passes through the hinge hole 24. The fixing plate 19 has a number of second fixing holes 18 arranged in a circle around the axis of the hinge hole 24. Correspondingly, the first connecting arm 16 has a number of third fixing holes 20 arranged in a circle around the axis of the hinge hole 24. The first fixing rod 21 can lock the mounting roller 4 after the angle is adjusted by passing through the second fixing holes 18 and the third fixing holes 20 one by one.

[0035] In this embodiment, the installation method of a car bumper with an adjustable light groove structure is the same as that in embodiment 1, except that: in step 5, when the mounting roller 4 has a first connecting arm 16 and a second connecting arm 17, the first connecting arm 16 rotates around the hinge hole 24 with the support of the second connecting arm 17, thereby further fine-tuning the tilt angle of the mounting roller 4 and the mounting frame 3. Step 6: The first fixing rod 21 passes through the second fixing hole 18 and the third fixing hole 20 one by one to complete the final fixation of the tilt angle of the first connecting arm 16 and the mounting frame 3.
