Description

Technical Field

[0001] The utility model relates to the technical field of truck shock absorption, in particular to a shock absorption structure for a truck headlight. Background Art

[0002] A truck, also known as a freight truck, belongs to the category of commercial vehicles. It includes dump trucks, towing trucks, off-road trucks in non-road and no-road areas, and various vehicles manufactured specifically for special needs. Generally, it can be divided into heavy and light types according to the weight of the vehicle. No matter which type of truck, the working environment is relatively complex. These trucks will generate strong vibrations when passing through rough roads, and due to the complex road conditions, braking often occurs during the driving process of the truck. Since the lamp cover of the truck headlight and the bumper have a clearance fit, and the material of the truck headlight is usually a relatively thin plastic material, during sudden braking or bumpy driving, the lamp housing of the truck headlight will continuously impact with the bumper. After long-term use or when the impact is large, the lamp housing will crack or break, etc. Then, once it rains or there is a sprinkler during the continuous driving of the truck, the inside of the lamp housing will be soaked by water, resulting in the failure of the headlight. When the truck headlight is not on during night driving, it will pose a great threat to the driving safety of the truck driver. Content of the Utility Model

[0003] The purpose of the utility model is to provide a shock absorption structure for a truck headlight. The shock absorption structure has strong earthquake resistance performance and anti-disengagement performance, can not only increase the service life of the truck headlight, but also has a simple structure, low cost and is easy to install.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A shock absorption structure for a truck headlight includes a shock absorption pad and a shock absorption pad mounting seat fixedly connected to an external bumper. The shock absorption pad includes a gasket and a clamping member fixedly connected to one side of the gasket; the shock absorption pad mounting seat includes a cavity, and a mounting hole is provided on the top plate of the cavity, and the clamping member is detachably clamped in the mounting hole.

[0006] Preferably, a first opening is provided on one side of the cavity, and a second opening communicating the first opening and the mounting hole is provided on the top surface of the cavity. The narrow end of the second opening is connected to the mounting hole and forms a limit with the mounting hole. The clamping member includes a connecting column, and the end of the connecting column expands outward to form a clamping head. The clamping head can be clamped below the mounting hole. When the connecting column enters the mounting hole from the second opening, the limit clamps the connecting column to prevent the connecting column from disengaging from the mounting hole. At this time, the clamping head is located in the first cavity.

[0007] Preferably, the mounting hole is a circular hole, the connecting column is a cylinder, the cylinder is matched with the mounting hole, and the cylinder and the clamping joint are connected through a guiding inclined surface.

[0008] Preferably, a groove is provided on one side of the gasket away from the clamping member, and a plurality of intersecting partitions are provided inside the groove to make the groove in a grid shape.

[0009] Preferably, the edge of the shock pad mounting seat extends toward the side close to the shock pad to form a clamping groove, the clamping groove is matched with the shock pad, and the top surface of the clamping groove is lower than the top surface of the shock pad.

[0010] Preferably, when the clamping joint is clamped with the mounting hole, there is a gap between the clamping joint and the bottom plate of the first cavity.

[0011] Preferably, a supporting clamping platform is provided on one side of the connecting column close to the second opening. When the connecting column is clamped with the mounting hole, the supporting clamping platform is located in the second opening.

[0012] Preferably, the gasket gradually thickens from one end of the supporting clamping platform to the other end.

[0013] Preferably, the shock pad is a rubber shock pad.

[0014] Preferably, the gasket and the supporting clamping platform are integrally formed.

[0015] In the above technical solution, the connection between the shock pad and the shock pad mounting seat is realized by detachably clamping the clamping member in the mounting hole, which is simple and convenient. And the shock pad is a rubber shock pad, with low cost, strong flexibility and large elasticity. The rubber shock pad contacts the lamp housing of the truck headlight. When the truck is driving on a bumpy road or braking suddenly, it provides shock absorption support for the lamp housing, avoids hard collision between the lamp housing and the bumper, and prevents damage to the lamp housing, thus improving the service life of the truck headlight.

[0016] By providing a first opening on one side of the cavity and a second opening on the top surface of the cavity that connects the first opening and the mounting hole, when connecting the shock pad to the shock pad mounting seat, the connecting column enters the mounting hole along the second opening, and the first opening provides space for the clamping head to enter the cavity. The second opening gradually narrows from the side near the first opening to the side near the mounting hole to guide the connecting column. The narrowest end of the second opening is connected to the mounting hole and forms a limit with the mounting hole. When the connecting column enters the mounting hole from the second opening, the limit exerts pressure on the outer wall of the connecting column, causing the connecting column to deform. When the connecting column enters the mounting hole, the connecting column returns to its original shape, and the limit clamps the connecting column to prevent the connecting column from slipping out of the mounting hole. Further, by setting the mounting hole as a circular hole and the connecting column as a cylinder, the outer diameter of the cylinder matches the mounting hole to prevent the connecting column from slipping out of the mounting hole when being squeezed after entering the mounting hole, and at the same time, to prevent the connecting column from wobbling back and forth in the mounting hole. By providing a support clamping platform on one side of the connecting column close to the second opening, the support clamping platform is integrally formed with the connecting column, making the structure more stable. When the connecting column is clamped with the mounting hole, the support clamping platform is located in the second opening to provide secondary limitation to the shock pad, increasing the connection between the shock pad and the shock pad mounting seat and preventing rotation between the shock pad and the shock pad mounting seat. By providing a groove on the side of the gasket away from the clamping part and providing a number of intersecting partitions inside the groove to make the groove grid-shaped, when the truck travels on a bumpy road surface or brakes suddenly, the grid-shaped groove supports the lamp housing while the grid-shaped connection is more prone to deformation.

[0017] By providing a clamping groove, the clamping groove cooperates with the edge of the shock pad to fix the shock pad inside the clamping groove, providing secondary reinforcement to the shock pad, further preventing the shock pad from detaching from the shock pad mounting seat. At the same time, the clamping groove limits the shock pad to prevent the shock pad from rotating in the mounting hole along the direction of the connecting column. And the top surface of the clamping groove is lower than the top surface of the shock pad, so that when the clamping groove clamps the gasket, it will not affect the shock absorption support of the gasket to the lamp housing.

Specific embodiments

[0024] The following further describes the present utility model in conjunction with the accompanying drawings:

[0025] As Figures 1 to 5 shown, the shock-absorbing structure of the front lamp of this truck includes a shock pad 10 and a shock pad mounting seat 20 fixedly connected to the external bumper. The shock pad 10 includes a gasket 11 and a clamping member 14 fixedly connected to one side of the gasket 11. The shock pad mounting seat 20 includes a cavity 22, and a mounting hole 26 is provided on the top plate of the cavity 22. The connection between the shock pad 10 and the shock pad mounting seat 20 is realized by detachably clamping the clamping member 14 in the mounting hole 26, which is simple and convenient. The shock pad 10 is a rubber shock pad 10, which has low cost, strong flexibility and large elasticity. The rubber shock pad 10 contacts the lamp housing of the front lamp of the truck. When the truck is driving on a bumpy road or braking suddenly, it provides shock-absorbing support for the lamp housing, avoiding hard collision between the lamp housing and the bumper, causing damage to the lamp housing, and improving the service life of the truck lamp.

[0026] The snap-in part 14 includes a connecting column 15. One end of the connecting column 15 is connected to the gasket 11, and the end of the other end expands outward to form a snap joint 18. The gasket 11, the connecting column 15, and the snap joint 18 are integrally formed. The snap joint 18 is in interference fit with the mounting hole 26 to prevent the snap-in part 14 from disengaging from the mounting hole 26. On one side of the cavity 22, there is a first opening 23. On the top surface of the cavity 22, there is a second opening 24 connecting the first opening 23 and the mounting hole 26. When connecting the shock pad 10 to the shock pad mounting seat 20, the connecting column 15 enters the mounting hole 26 along the second opening 24. At this time, the first opening 23 provides space for the snap joint 18 to enter the cavity 22. The second opening 24 gradually narrows from the side near the first opening 23 to the side near the mounting hole 26 to guide the connecting column 15. The narrowest end of the second opening 24 is connected to the mounting hole 26 and forms a limit 25 with the mounting hole 26. When the connecting column 15 enters the mounting hole 26 from the second opening 24, the limit 25 exerts extrusion on the outer wall of the connecting column 15, causing the connecting column 15 to deform. When the connecting column 15 enters the mounting hole 26, the connecting column 15 returns to its original shape, and the limit 25 snaps onto the connecting column 15 to prevent the connecting column 15 from disengaging from the connecting hole. Further, the mounting hole 26 is a circular hole, and the connecting column 15 is a cylinder. The outer diameter of the cylinder is matched with the mounting hole 26 to prevent it from disengaging from the mounting hole 26 when being squeezed after entering the mounting hole 26, and at the same time, to prevent the connecting column 15 from swaying back and forth in the mounting hole 26. Further, a guiding inclined surface 17 is provided for transitional connection between the connecting column 15 and the snap joint 18 to strengthen the connection performance between the two, and at the same time, to prevent the connecting column 15 from moving up and down in the mounting hole 26.

[0027] On the side of the gasket 11 away from the snap-in part 14, there is a groove 12. Inside the groove 12, there are several intersecting partitions 13 to make the groove 12 grid-shaped. When the truck travels on a bumpy road or brakes suddenly, the grid-shaped groove 12 supports the lamp housing while the grid-shaped connection is more prone to deformation.

[0028] In a preferred embodiment, on the side of the connecting column 15 close to the second opening 24, there is a supporting snap table 16. The supporting snap table 16 is integrally formed with the connecting column 15, and the structure is more stable. When the connecting column 15 is snap-connected to the mounting hole 26, the supporting snap table 16 is located in the second opening 24 to perform secondary limiting 25 on the shock pad 10, increasing the connection between the shock pad 10 and the shock pad mounting seat 20 and preventing rotation between the shock pad 10 and the shock pad mounting seat 20. Further, the gasket 11 gradually thickens from one end of the supporting snap table 16 to the other end to better adapt to the gap between the truck headlight and the bumper.

[0029] In a preferred embodiment, a clamping groove 21 is formed by extending the edge of the shock pad mounting seat 20 near the shock pad 10. The clamping groove 21 cooperates with the edge of the shock pad 10 to fix the shock pad 10 inside the clamping groove 21, providing secondary reinforcement to the shock pad 10 and further preventing the shock pad 10 from separating from the shock pad mounting seat 20. At the same time, the clamping groove 21 positions the shock pad 10 to prevent the shock pad 10 from rotating along the connecting column 15 in the mounting hole 26. In this embodiment, the top surface of the clamping groove 21 is lower than the top surface of the shock pad 10, so that while the clamping groove 21 clamps the gasket 11, it does not affect the shock absorption and support of the gasket 11 for the lamp housing.

[0030] In a preferred embodiment, when the clamping head 18 is clamped with the mounting hole 26, there is a gap between the clamping head 18 and the bottom plate of the first cavity 22. When the lamp housing contacts the shock pad 10, the lamp housing generates a downward pressure on the shock pad 10, causing the shock pad 10 to deform. At the same time, a pressure is applied to the shock pad mounting seat 20, causing the top plate of the cavity 22 to be depressed into the cavity 22, increasing the deformation space of the shock absorption assembly. And when the clamping head 18 contacts the bottom plate of the cavity 22, the top plate of the cavity 22 is subjected to the greatest force, and at this time, the top plate of the cavity 22 will not be damaged.

[0031] This embodiment is only an illustration of the concept and implementation of the present invention and does not limit it. Under the concept of the present invention, technical solutions without substantial transformation are still within the scope of protection.
