Description

Technical Field

[0001] This utility model relates to the field of ground lighting technology, and more particularly to automotive ground lighting with uniform illuminance. Background Technology

[0002] Car puddle lights are lights installed under vehicles to illuminate the area beneath and around the vehicle. They provide additional illumination when the vehicle is driving or parked at night, helping the driver better observe road conditions and the surrounding environment, especially in dimly lit areas such as parking lots and residential roads. This effectively prevents accidents such as collisions or scratches caused by poor visibility. Furthermore, puddle lights also have a decorative effect, enhancing the overall aesthetics of the vehicle.

[0003] To reduce the glare caused by excessively strong car puddle lights, diffusers are usually installed on the surface of the puddle lights. The diffusers disperse the light, creating a more uniform illumination. However, the diffusers are usually fixed to the light strip and the bottom of the car body with bolts. The bolts must be removed with the help of tools such as screwdrivers, and the scope of disassembly is limited by the tools used. It is also inconvenient to replace them when a fault is found while on the road. To solve this problem, a car puddle light with uniform illumination is provided. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a car ground illumination lamp with uniform illuminance, comprising:

[0005] The mounting housing has an embedded light groove at the bottom, at least one mounting groove starting from the top of the embedded light groove, a sliding groove on one side of each mounting groove, a connecting groove inside the mounting housing, and a vertical groove inside the mounting housing.

[0006] A light-emitting strip is embedded in a recessed light groove. At least one mounting block is fixedly provided on the upper end of the light-emitting strip. Limiting holes are provided on one side of each mounting block.

[0007] A limiting mechanism is installed inside the mounting housing. The limiting mechanism includes at least one limiting rod and at least one first elastic element. The limiting rod is slidably disposed in a sliding groove. One end of the first elastic element is fixedly connected to one end of the limiting rod, and the other end of the first elastic element is fixedly connected to the inner wall of the sliding groove. A movable plate is slidably disposed in the connecting groove. The sides of the movable plate are fixedly connected to the limiting rod. A push rod is slidably disposed in the vertical groove. The push rod has a threaded post threaded on its internal thread. The threaded post is rotatably connected to the mounting housing, and a knob is fixedly disposed at the bottom end of the threaded post.

[0008] As an improvement to the above technical solution, a push plate is slidably provided in the mounting groove, and a second elastic element is fixedly provided on the top of the mounting groove, with the other end of the second elastic element fixedly connected to the push plate.

[0009] As an improvement to the above technical solution, the top of the push rod is inclined, one end of the moving plate is triangular, the triangular end of the moving plate passes through the connecting groove and is inserted into the vertical groove, and the inclined surface of the top of the push rod is in contact with the inclined surface of the triangular end of the moving plate.

[0010] As an improvement to the above technical solution, the other end of the limiting rod is in the shape of a right triangle, with the inclined surface of the right triangle end of the limiting rod facing downwards. The right triangle end of the limiting rod passes through the sliding groove and is inserted into the mounting groove.

[0011] As an improvement to the above technical solution, the threaded post penetrates the bottom of the vertical groove, the knob is located at the end of the threaded post penetrating the vertical groove, and the lower surface of the knob is flush with the lower surface of the mounting housing.

[0012] The beneficial effects of this utility model are:

[0013] 1. By using the mounting block, limiting hole, limiting rod, first elastic element, moving plate, push rod, threaded column, and knob in combination, when installing the light strip, it is placed into the embedded light groove and pushed upward. When it encounters the limiting rod, it presses upward on the inclined surface of the right-angled triangle end of the limiting rod. By pressing the inclined surface of the limiting rod, the limiting rod is pushed into the sliding groove. When the light strip is fully inserted into the embedded light groove, the first elastic element pushes the limiting rod into the limiting hole on the side of the mounting block, completing the quick installation of the light strip. When removing it, the light strip can be removed simply by turning the knob, so that the installation of the light strip does not require other tools.

[0014] 2. With the cooperation of the push plate and the second elastic element, when the light strip is installed, the installation block will push the push plate upward and squeeze the second elastic element. When the light strip needs to be disassembled, when the limiting rod is disengaged from the limiting hole, the second elastic element can push the light strip out of the embedded light groove through the push plate to facilitate its removal.

[0020] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0021] To reduce the glare caused by excessively strong car puddle lights, diffusers are usually installed on the surface of the puddle lights. The diffusers disperse the light, creating a more uniform illumination. However, the diffusers are usually fixed to the puddle lights and the bottom of the car body with bolts. These bolts must be removed with a screwdriver or similar tool, which limits the range of disassembly and makes replacement inconvenient when a malfunction is discovered while out and about.

[0022] To resolve this issue, please refer to Figure 1-4 A car ground light with uniform illumination includes: a mounting housing 1, an embedded lamp groove 11 at the bottom of the mounting housing 1, at least one mounting groove 12 at the top of the embedded lamp groove 11, a sliding groove 13 on one side of the mounting groove 12, a connecting groove 14 inside the mounting housing 1, and a vertical groove 15 inside the mounting housing 1.

[0023] A light strip 2 is embedded in the embedded light groove 11. At least one mounting block 21 is fixedly provided on the upper end of the light strip 2. Limiting holes 22 are provided on one side of each mounting block 21.

[0024] The limiting mechanism 3 is installed inside the mounting housing 1. The limiting mechanism 3 includes at least one limiting rod 31 and at least one first elastic element 32. The limiting rod 31 is slidably disposed in the sliding groove 13. One end of the first elastic element 32 is fixedly connected to one end of the limiting rod 31, and the other end of the first elastic element 32 is fixedly connected to the inner wall of the sliding groove 13. A movable plate 33 is slidably disposed in the connecting groove 14. The sides of the movable plate 33 are fixedly connected to the limiting rod 31. A push rod 34 is slidably disposed in the vertical groove 15. A threaded post 35 is threaded in the push rod 34. The threaded post 35 is rotatably connected to the mounting housing 1. A knob 36 is fixedly disposed at the bottom end of the threaded post 35.

[0025] In use, the mounting housing 1 is welded and fixed to the bottom of the car body. The lower surface of the mounting housing 1 is flush with the bottom of the car body. When installing the light strip 2, the light strip 2 is aligned with the embedded lamp groove 11 and pushed upward into the embedded lamp groove 11. The light strip 2 drives the mounting block 21 to move upward. When it moves to the limiting rod 31, it will squeeze the inclined surface of the right-angled triangle end of the limiting rod 31. Through the squeezing of the inclined surface, the limiting rod 31 is pushed into the sliding groove 13 and squeezes the first elastic member 32, so that the light strip 2 can be fully embedded into the lamp groove 11. After being embedded, the first elastic member 32 pushes the limiting rod 31 into the sliding groove 13. Insert the positioning rod 31 into the limiting hole 22. The light strip 2 is fixed in place by the mounting block 21 and the limiting hole 22. When the light strip 2 needs to be disassembled and replaced, turn the knob 36. The knob 36 drives the threaded column 35 to rotate. The rotation of the threaded column 35 drives the push rod 34 to move upward. The upward movement of the push rod 34 passes through the inclined surface on the push rod 34 and the inclined surface on the moving plate 33, pushing the moving plate 33 into the connecting groove 14. The moving plate 33 drives the limiting rod 31 to move into the sliding groove 13 and disengage from the limiting hole 22. The limiting of the mounting block 21 is released, and the light strip 2 can be removed.

[0026] The uniform illumination of the light strip 2 is usually achieved by dispersing the light emitted by the light strip 2 through the distribution of multiple light sources, the design of optical lenses and reflectors, thereby reducing the intensity of the light and achieving uniform illumination. This solution is widely used in the prior art, so it is not described in detail in this embodiment.

[0027] In the specific implementation process, such as Figure 2 As shown, a push plate 41 is slidably provided in the mounting groove 12, and a second elastic member 42 is fixedly provided on the top of the mounting groove 12. The other end of the second elastic member 42 is fixedly connected to the push plate 41.

[0028] When in use, when the light strip 2 is installed, it pushes the push plate 41 to squeeze the second elastic member 42. The second elastic member 42 pushes the mounting block 21 downward through the push plate 41, so that the upper surface of the limiting rod 31 fits against the inner wall of the limiting hole 22, reducing the shaking of the light strip 2. When the light strip 2 is disassembled, the push plate 41 can also push the light strip 2 to be better removed from the embedded lamp slot 11.

[0029] In the specific implementation process, such as Figure 3 As shown, the top of the push rod 34 is inclined, and one end of the moving plate 33 is triangular. The triangular end of the moving plate 33 passes through the connecting groove 14 and is inserted into the vertical groove 15. The inclined surface of the top of the push rod 34 is in contact with the inclined surface of the triangular end of the moving plate 33.

[0030] In use, the end of the movable plate 33 is triangular, which allows it to move when pressing the inclined plane, thereby changing the direction of the force. The triangular end of the movable plate 33 is inserted into the vertical groove 15, so that when the push rod 34 moves upward, it can push the movable plate 33 towards the connecting groove 14.

[0031] In the specific implementation process, such as Figure 2 As shown, the other end of the limiting rod 31 is in the shape of a right triangle. The inclined surface of the right triangle end of the limiting rod 31 is set downward. The right triangle end of the limiting rod 31 passes through the sliding groove 13 and is inserted into the mounting groove 12.

[0032] When in use, the right-angled triangular end of the limiting rod 31 faces downwards, and when it is subjected to an upward force, it can be pushed to move. The right-angled triangular end of the limiting rod 31 is inserted into the mounting groove 12, so that it can be inserted into the limiting hole 22 when it is not squeezed, so that it can limit and fix the light strip 2.

[0033] In the specific implementation process, such as Figure 3 As shown, the threaded post 35 penetrates the bottom of the vertical groove 15, and the knob 36 is located at the end of the threaded post 35 penetrating the vertical groove 15. The lower surface of the knob 36 is flush with the lower surface of the mounting housing 1.

[0034] In use, the threaded post 35 passes through the bottom of the vertical groove 15, making it easy to rotate the threaded post 35. The knob 36 at the through end allows the threaded post 35 to be rotated by hand without the need for other tools. The lower surface of the knob 36 is flush with the bottom of the mounting housing 1, which can reduce bumps and make it more aesthetically pleasing.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
