Description

Technical Field

[0001] This utility model relates to an installation structure for a lamp. Background Technology

[0002] As cars become increasingly common in daily life, traffic safety is also being improved. Optimizing automotive components (lighting) is crucial for ensuring efficient traffic flow while protecting personal safety. Currently, judging from the development trends of various car brands, front continuous lights are becoming more and more common and popular in car designs. Front continuous lights can greatly enhance the visibility of the front of the car, while also making the car more technologically advanced and futuristic.

[0003] However, the large size of the front continuous light also poses significant safety hazards: 1. It has many components that it works with (front bumper, hood) and the clearance between them is small. If the front continuous light cannot move backward when a pedestrian collides with a vehicle, it will cause significant injury to the pedestrian and cannot effectively protect the pedestrian; 2. The front continuous light is heavy, and the accessories for installing it need to be very rigid. If it does not deform and move backward when a pedestrian collides with a vehicle, it will cause great injury to the pedestrian and cannot effectively protect the pedestrian. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a lamp mounting structure that effectively solves the issues mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A lamp mounting structure includes a vehicle body sheet metal and a lamp mounting bracket. The front part of the lamp mounting bracket is fixed to the vehicle body sheet metal by multiple snap-fit ​​structures, and the rear part is fixed to the vehicle body sheet metal by multiple bolt fastening structures. The snap-fit ​​structure includes a snap-fit ​​base and a snap-fit ​​connector fixed at the bottom center of the snap-fit ​​base. The vehicle body sheet metal has multiple snap-fit ​​holes that match the snap-fit ​​connectors. There are gaps between the front and rear ends of the snap-fit ​​connectors and the front and rear ends of the snap-fit ​​holes.

[0007] Preferably, the bolt fastening structure includes a round hole in the body sheet metal, a strip hole in the lamp mounting bracket, and a fastening bolt, wherein the strip hole matches the round hole, and the fastening bolt passes through the round hole and the strip hole to fix the body sheet metal and the lamp mounting bracket.

[0008] Preferably, the front and rear ends of the snap-fit ​​connector are respectively provided with a mounting hole, and the lamp mounting bracket is provided with screw holes that match the mounting holes. The snap-fit ​​connector is fastened by screwing the screw from bottom to top through the mounting hole into the screw hole.

[0009] Preferably, the snap-fit ​​connector includes two snap-fit ​​connector units arranged symmetrically, with the two snap-fit ​​connector units located on the left and right sides of the snap-fit ​​base, respectively.

[0010] Preferably, the left and right sides of the snap-fit ​​base extend downward to form support bosses, and the top of the snap-fit ​​connector is fixed to the support bosses.

[0011] Preferably, the card holder has a positioning hole in the center longitudinal direction, and the lamp mounting bracket has a positioning platform that matches the positioning hole.

[0012] Preferably, the card holder, support boss, and card connector are integrally formed.

[0013] The innovative points of this utility model are:

[0014] 1. Snap-fit ​​structure and gap design:

[0015] The front of the lamp mounting bracket is fixed to the body sheet metal via a snap-fit ​​structure (snap-fit ​​base and snap-fit ​​connector). The snap-fit ​​connector is inserted into the snap-fit ​​hole of the body sheet metal, and there is a gap between the front and rear ends of the snap-fit ​​connector and the snap-fit ​​hole. This design allows the lamp to move back and forth when it is hit, avoiding rigid obstruction and thus reducing injury to pedestrians.

[0016] 2. Bolt fastening structure and slotted hole design:

[0017] The rear of the lamp mounting bracket is fixed to the body sheet metal by bolt fastening structure. The body sheet metal has round holes, and the lamp mounting bracket has strip holes. The strip holes provide a certain displacement space. When a collision occurs, the lamp can move along the direction of the strip holes to further absorb the impact energy.

[0018] 3. Dual-card connector unit and supporting boss:

[0019] The snap-fit ​​connector features two symmetrical snap-fit ​​units located on the left and right sides of the snap-fit ​​base, respectively, and are fixed by support bosses. This structure enhances the stability of the snap-fit, allowing for uniform deformation under force during collisions and avoiding localized stress concentration. At the same time, the downward-protruding support bosses provide space for screw fixing at both ends of the snap-fit ​​base.

[0020] 4. Positioning holes and positioning platform:

[0021] The card holder has a positioning hole in the center, and the lamp mounting bracket has a matching positioning platform. This design ensures accurate alignment during installation, simplifies the assembly process, and improves the overall integrity and reliability of the structure.

[0022] 5. One-piece molding process:

[0023] The snap-fit ​​base, support boss, and snap-fit ​​connector are manufactured using a one-piece molding process, which reduces the number of connecting parts, improves the strength and durability of the structure, and reduces the complexity of production.

[0024] The beneficial effects of this utility model are:

[0025] 1. Improve pedestrian protection performance:

[0026] The gaps and slotted holes in the snap-fit ​​and bolt fastening structures allow the lamps to shift back and forth during a collision, absorbing impact energy and significantly reducing the risk of injury to pedestrians.

[0027] 2. Enhance installation stability:

[0028] The design of the dual-pin connector unit and the support boss improves the stability of the lamp installation and ensures that the lamp will not loosen due to vibration during vehicle operation;

[0029] 3. Simplified installation and maintenance:

[0030] The matching of the positioning holes and the positioning platform simplifies the installation process and improves assembly efficiency; at the same time, the modular design facilitates later maintenance or replacement.

[0031] 4. Optimize force distribution:

[0032] The one-piece molding process and symmetrical structural design make the stress distribution more uniform, avoid local stress concentration, and extend the service life of the lamps and installation structures.

[0033] This utility model effectively solves the safety hazards of front through lights in collisions through a matching design of snap-fit ​​and bolt fastening. At the same time, it takes into account the convenience of installation and structural reliability. The bolt fastening structure not only facilitates the forward and backward movement of the lamp mounting bracket to absorb energy, but also allows for the forward and backward adjustment of the lamp mounting bracket during installation, reducing the manufacturing precision requirements.

[0053] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0054] like Figure 1-13 As shown, a lamp mounting structure includes a body sheet metal 1 and a lamp mounting bracket 2. The front part of the lamp mounting bracket 2 is fixed to the body sheet metal 1 by multiple snap-fit ​​structures 3, and the rear part is fixed to the body sheet metal 1 by multiple bolt fastening structures 4. The snap-fit ​​structure 3 includes a snap-fit ​​seat 31 and a snap-fit ​​connector 32 fixed at the bottom center of the snap-fit ​​seat 31. The body sheet metal 1 has multiple snap-fit ​​holes 11 that match the snap-fit ​​connector 32. A gap 5 is left between the front and rear ends of the snap-fit ​​connector 32 and the front and rear ends of the snap-fit ​​holes 11.

[0055] The bolt fastening structure 4 includes a round hole 41 on the body sheet metal 1, a strip hole 42 on the lamp mounting bracket 2, and a fastening bolt (not shown in the figure). The strip hole 42 matches the round hole 41, and the fastening bolt passes through the round hole 41 and the strip hole 42 to fix the body sheet metal 1 and the lamp mounting bracket 2.

[0056] The front and rear ends of the snap-fit ​​base 31 are respectively provided with a mounting hole 33. The lamp mounting bracket 2 is provided with a screw hole 21 that matches the mounting hole 33. The snap-fit ​​base 31 is fastened by screws (not shown in the figure) passing through the mounting hole 33 from bottom to top and then screwing into the screw hole 21.

[0057] The snap-fit ​​connector 32 includes two snap-fit ​​connector units arranged symmetrically, with the two snap-fit ​​connector units located on the left and right sides of the snap-fit ​​base 31, respectively.

[0058] The left and right sides of the snap-fit ​​base 31 extend downward to form support bosses 34, and the top of the snap-fit ​​unit is fixed to the support bosses 34.

[0059] The center of the card holder 31 is provided with a positioning hole 35, and the lamp mounting bracket 2 is fixed with a positioning platform 22 that matches the positioning hole 35.

[0060] The card holder 31, the support boss 34 and the card connector 32 are integrally formed.

[0061] This invention achieves stable fixing of the lamp during normal driving through a specific snap-fit ​​and bolt fastening mechanism, while allowing the lamp to shift during a collision to absorb impact energy, thereby improving pedestrian protection performance. The detailed working principle is as follows:

[0062] 1. Dynamic displacement design of the snap-fit ​​structure:

[0063] The mating of the snap-fit ​​connector and the snap-fit ​​hole:

[0064] The front of the lamp mounting bracket is connected to the body sheet metal via a snap-fit ​​structure. The snap-fit ​​connector is inserted into the snap-fit ​​hole in the body sheet metal, and a gap is left between the front and rear ends of the snap-fit ​​connector and the snap-fit ​​hole. This design allows:

[0065] Under normal operating conditions: The gapless fit between the clip and the clip hole (in the left and right directions) ensures the stability of the lamp installation and prevents loosening due to vibration during driving;

[0066] Collision condition: When a vehicle collides with a pedestrian, the impact force pushes the lamp backward, and the snap-fit ​​connector can slide back and forth within the gap of the snap-fit ​​hole, thereby avoiding rigid obstruction and reducing injury to the pedestrian;

[0067] Dual-clamp connector unit and support boss:

[0068] The snap-fit ​​connector consists of two symmetrical units, secured by a support boss. This design:

[0069] Distribute the stress and avoid localized stress concentration;

[0070] The support boss provides space for screw installation at both ends of the connector, ensuring structural integrity.

[0071] 2. Energy absorption mechanism of bolt fastening structure:

[0072] Fitting of strip holes and round holes:

[0073] The rear of the lamp mounting bracket is connected to the vehicle body sheet metal via a bolt fastening structure, wherein:

[0074] The body panel has round holes, and the lamp mounting bracket has strip-shaped holes (oblong holes).

[0075] Under normal operating conditions: After the bolts pass through the round holes and the strip holes, tighten them to fix the position of the lamp mounting bracket;

[0076] Collision condition: The impact force causes the lamp mounting bracket to move backward, and the bolts slide in the slotted hole, allowing the lamp to move backward as a whole to absorb the impact energy. The length of the slotted hole determines the maximum displacement, thereby controlling the energy absorption effect.

[0077] 3. Positioning and installation optimization:

[0078] Positioning holes and positioning platforms:

[0079] The positioning hole in the center of the connector matches the positioning platform on the lamp mounting bracket, ensuring quick alignment during installation and improving assembly accuracy and efficiency;

[0080] One-piece molding process:

[0081] The snap-fit ​​base, support boss, and snap-fit ​​connector are integrally molded, reducing connecting parts, enhancing structural strength, and reducing production complexity.

[0082] When using this utility model:

[0083] During normal driving: the gaps in the snap-fit ​​structure do not play a role, the bolt fastening structure firmly fixes the lamp mounting bracket, and the double snap-fit ​​connector and support boss provide uniform support to ensure the stability of the lamp;

[0084] When a collision occurs: The impact force first acts on the front of the lamp, and the snap-fit ​​connector slides backward in the gap of the snap-fit ​​hole to initially absorb energy. As the impact force increases, the rear bolt moves along the strip hole, and the lamp mounting bracket moves backward as a whole to further buffer the impact. During the displacement, the support boss and the double snap-fit ​​connector deform evenly to avoid structural breakage. When the impact force is too large, the snap-fit ​​connector will fall directly off from the snap-fit ​​hole, causing the front of the lamp mounting bracket to detach from the body sheet metal.

[0085] This invention cleverly balances the contradiction between "rigid fixation" and "flexible energy absorption," and is suitable for the safe installation requirements of large lighting fixtures such as front through lights.

[0086] 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.
