Description

Technical Field

[0001] The utility model relates to the technical field of vehicle ceiling lamps, in particular to a commercial vehicle ceiling lamp. Background Art

[0002] Business cars are equipped with panoramic sunroof, electric sunroof, electric adjustable seats, body ESP, xenon headlights, GPS navigation, cruise control, leather seats, reversing radar, fully automatic air conditioning, multi-function steering wheel, LED headlights, reversing image, keyless start, seat heating, daytime running lights, automatic parking, Bluetooth / car phone, etc. Business cars refer to vehicles suitable for business occasions. In order to meet lighting needs and create a comfortable and bright riding environment, ceiling lights are basically installed on the top of business cars.

[0003] Existing ceiling lights for commercial vehicles require the roof to be cut during installation, and the base is then bolted on before the ceiling lights are installed. This not only causes irreversible damage to the roof, but also makes it impossible to replace other styles of ceiling lights once installed. At the same time, some ceiling lights that do not require cutting the roof have a certain curvature of the roof, so when installing the ceiling lights, the mounting plate needs to be adjusted before installation so that it can be replaced to fit the curvature of the roof, which is very troublesome. Utility Model Content

[0004] The purpose of the utility model is to provide a ceiling lamp for a commercial vehicle to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a ceiling lamp for commercial vehicles, comprising a mounting bar, a bending bar, a first positive and negative screw rod, a second positive and negative screw rod, a limit slider and an adjusting slider, a pair of limit grooves are provided above the mounting bar, a cavity is provided inside the mounting bar, limit grooves are provided on both sides of the cavity, the limit slider is slidably connected inside the limit groove, the limit slider is slidably connected inside the limit groove, the limit slider is slidably connected inside the limit groove, both ends of the first positive and negative screw rod are threadedly connected to the limit slider, both ends of the second positive and negative screw rod are threadedly connected to the limit slider, the limit slider is movably connected to both ends of the bending bar, a connecting rod is movably connected above the limit slider, one end of the connecting rod away from the limit slider is movably connected to the adjusting slider, a pair of adjusting grooves are provided at the bottom of the bending bar, the adjusting slider is slidably connected to the inside of the adjusting groove, and the mounting bar is fixedly connected to the top of the mounting plate by bolts.

[0006] Preferably, the bending bar is located above the mounting bar, and the first forward and reverse screw rods and the second forward and reverse screw rods are both movably connected to the interior of the mounting bar.

[0007] Preferably, the cavity is connected to the limiting groove, a gear component is fixed through the second forward and reverse screw rods, a worm component is meshingly connected to one side of the gear component, and the worm component and the gear component are movably connected to the interior of the cavity.

[0010] Preferably, a lampshade is installed below the mounting plate.

[0011] Preferably, a lamp body is installed inside the lampshade.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] First, the utility model provides a mounting strip and a bending strip and their respective objects. When the lamp body and the object need to be installed, the first positive and negative screw rods can be rotated by a tool so that the limiting sliders are brought closer to each other, thereby bending the bending strip. At this time, the bending strip and the object are fitted to the roof, and the tool is continued to be used to rotate the first positive and negative screw rods until the bending strip can roughly fit to the roof. At this time, the bending strip is fixed to the roof by bolts passing through the connecting plate, and the mounting plate is successively installed on the bottom of the mounting strip by bolts, and the lamp body is installed under the mounting plate. Finally, the ceiling lamp can be installed without cutting the top surface of the vehicle, which makes the installation more convenient and quick.

[0014] Secondly, the utility model provides mounting strips and bending strips and their respective objects. After the first forward and reverse screw rods are rotated by a tool so that the bending strip roughly fits the roof, the tool can be used to connect the lower part of the worm gear and rotate it, thereby rotating the gear part and the second forward and reverse screw rods. At this time, the limiting sliders at both ends of the second forward and reverse screw rods will move closer to or away from each other, which can not only further bend the bending strip to a curvature close to fitting the roof, but also increase the overall supporting strength.

[0025] Through the above technical scheme, the two ends of the first positive and negative screw rod 25 and the second positive and negative screw rod 26 are movably connected inside the mounting strip 20 by means of holes, and the second positive and negative screw rod 26 is located above the first positive and negative screw rod 25; a connection port is welded at one end of the first positive and negative screw rod 25 for connecting external tools so as to allow the first positive and negative screw rod 25 to rotate; the bending strip 30 is an aluminum strip with a certain toughness, and its two ends are movably connected to the limiting slider 24 by means of a latch, so when the first positive and negative screw rod 25 rotates to allow the limiting slider 24 to move closer to each other, the bending strip 30 will bend as a whole, thereby facilitating its relative fit to the curvature of the roof; the two ends of the connecting rod 28 are movably connected by a convex shaft, so that it can rotate around the movable connection point, so when the limit sliders 27 move away from each other, the bending point of the bending strip 30 will be further added, allowing it to fit the roof more closely, while also increasing the overall structural strength.

[0026] Specifically, the cavity 23 is connected to the limiting groove 22 , and the second forward and reverse screw rod 26 penetrates and is fixed with a gear member 290 . One side of the gear member 290 is meshedly connected with a worm member 291 . The worm member 291 and the gear member 290 are both movably connected to the interior of the cavity 23 .

[0027] Through the above technical solution, when the bottom of the worm member 291 docks with the output end of the tool, it will rotate so that it can rotate with the gear member 290 and the second forward and reverse screw 26, thereby allowing the limiting sliders 27 on both sides to move closer to or away from each other.

[0028] Specifically, the worm member 291 penetrates the bottom of the movable connection mounting strip 20 .

[0029] Through the above technical solution, the worm gear 291 is composed of a shaft, a spiral member and a docking member, which are welded to each other.

[0030] Specifically, both sides of the mounting bar 20 and the bending bar 30 are welded with evenly arranged connecting plates 33 .

[0031] Through the above technical solution, the connecting plate 33 is used to facilitate the passing of bolts, so that the bending strip 30 is connected to the roof, and the mounting strip 20 is connected to the mounting plate 12.

[0032] Specifically, a lampshade 11 is installed below the mounting plate 12 .

[0033] Through the above technical solution, the mounting plate 12 is a mounting plate of the ceiling lamp and is used to receive objects below.

[0034] Specifically, the lamp body 10 is installed inside the lampshade 11 .

[0035] Through the above technical solution, the lamp body 10 and its components constitute a ceiling lamp for commercial vehicles.

[0036] During use, by setting the mounting strip 20 and the bending strip 30 and their respective objects, when the lamp body 10 and the object thereof need to be mounted, the first positive and negative screw rods 25 can be rotated by a tool so that the limiting sliders 24 are brought closer to each other, thereby bending the bending strip 30. At this time, the bending strip 30 and the object thereof are fitted to the roof, and the first positive and negative screw rods 25 are continuously rotated by a tool until the bending strip 30 can be roughly fitted to the roof. At this time, the bending strip 30 is fixed to the roof by bolts passing through the connecting plate 33, and the mounting plate 12 is mounted on the bottom of the mounting strip 20 by bolts in turn, and the lamp body 10 is mounted below the mounting plate 12. Finally, there is no need to cut the top surface of the car to install the ceiling light, which makes the installation more convenient and quick; by setting the installation strip 20 and the bending strip 30 and their respective objects, after the first positive and negative screw rod 25 is rotated by the tool so that the bending strip 30 roughly fits the roof, the tool can be used to connect the bottom of the worm gear 291 and rotate it to rotate the gear part 290 and the second positive and negative screw rod 26. At this time, the limiting sliders 27 at both ends of the second positive and negative screw rod 26 will move closer to or away from each other, which can not only further bend the bending strip 30 to a curvature close to fitting the roof, but also increase the overall support strength.
