[0031] The present application provides a lamp and also provides a vehicle including the lamp.

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] like Figure 1 As shown, a lamp can be applied to any scene requiring lighting. Preferably, the lamp is installed in the cab of a vehicle for reading lighting. The lamp includes a fixed component 1, a rotating component 2, and a lamp body 3. The fixed component 1 is fixedly installed in the scene requiring lighting. When the lamp is installed in the cab of a vehicle, the fixed component 1 is fixed to the interior of the cab; preferably, the lamp is installed on the ceiling of the cab. The fixed component 1 includes a fixed interference surface. The rotating component 2 is rotatably installed on the fixed component 1, and the rotating component 2 includes a rotational interference surface in frictional contact with the fixed interference surface. The lamp body 3 is fixed to the rotating component 2. When the rotational force applied to the rotating component 2 disappears, the rotational interference surface stops rotating relative to the fixed interference surface under the action of static friction, so that the rotating component 2 stops at the target angle.

[0034] It should be noted that the lamp is formed with a rotation center axis, and the rotating component 2 rotates relative to the fixed component 1 around the rotation center axis. Figure 1 The position indicated by the dotted line.

[0035] The fixed interference surface is a surface formed on fixed component 1 that remains stationary. The rotating interference surface is a surface formed on rotating component 2 that rotates relative to the fixed interference surface when rotating component 2 rotates relative to fixed component 1. The "interference" in the fixed interference surface and rotating interference surface is relative. The two surfaces are in frictional contact. When the two surfaces rotate relative to each other, rotational friction exists between them. When the two surfaces are relatively stationary, they are kept stationary by the action of static friction.

[0036] The "rotational force" may be a pushing force or a gripping force applied by a user to the rotating component 2. The "target angle" may be any angle that satisfies the lighting requirement.

[0037] The rotation of the lamp in the embodiment of the present application no longer relies on the cooperation of mechanical structures such as gears or free joints, but a fixed interference surface is formed on the fixed component 1, and a following interference surface is formed on the rotating component 2; when the rotating component 2 is subjected to a rotational force and rotates around the central axis of rotation, the following interference surface rotates with friction relative to the fixed interference surface, and the rotating component 2 will not shake during the rotation process, and the rotation force is easy to control during the product development stage and during use; when the rotational force applied to the rotating component 2 disappears, the following interference surface stops rotating relative to the fixed interference surface under the action of static friction, so that the rotating component 2 stops at the target angle; the lamp of the present application is not only low in cost, but also realizes the following stopping when the rotating component 2 rotates, so that the lamp can rotate freely and without shaking, and the lamp can be fixed at any target angle that meets the lighting requirements, and all angles can be used during the rotation process.

[0038] In certain embodiments of the present application, one of the fixed component 1 and the rotating component 2 is formed with a rotating hole, and the other is formed with a rotating shaft adapted to be mounted in the rotating hole. Along the central axis of the rotating hole, the contact surface between the fixed component 1 and the rotating component 2 forms a fixed interference surface, and the contact surface between the rotating component 2 and the fixed component 1 forms a rotating interference surface.

[0039] It should be noted that the central axis of the rotating hole coincides with the central axis of the rotating shaft, and the central axis of the rotating hole coincides with the central axis of rotation of the lamp.

[0040] The two surfaces of the fixed component 1 and the rotating component 2 that contact each other form a fixed interference surface and a rotating interference surface respectively, and the fixed interference surface and the rotating interference surface are both perpendicular to the central axis of rotation; as above, frictional contact between the fixed interference surface and the rotating interference surface is achieved to ensure the stop-and-go effect of the rotating component 2 relative to the fixed component 1.

[0041] In some embodiments, along the circumference of the rotating hole, one of the two transmission surfaces that are rotatably matched between the rotating hole and the rotating shaft is formed with a fixed interference surface, and the other is formed with a rotating interference surface.

[0042] It should be noted that: ① the fixed interference surface and the rotational interference surface can be respectively set only on the two surfaces where the fixed component 1 and the rotating component 2 are in contact with each other and are perpendicular to the center axis of rotation; ② the fixed interference surface and the rotational interference surface can be respectively set only on the two transmission surfaces where the fixed component 1 and the rotating component 2 are in rotation with each other; ③ the fixed interference surface and the rotational interference surface can be respectively set on the two surfaces where the fixed component 1 and the rotating component 2 are in contact with each other and are perpendicular to the center axis of rotation, and the fixed interference surface and the rotational interference surface can be respectively set on the two transmission surfaces where the fixed component 1 and the rotating component 2 are in rotation with each other.

[0043] As described above, the formation positions of the fixed interference surface and the rotating interference surface are enriched, and they can be selected according to actual needs, with strong flexibility and applicability.

[0044] Example 1

[0045] The rotating assembly 2 includes a rotating body 21 and a rotating shaft 22 fixed to the rotating body 21. The fixed assembly 1 includes a fixed bracket 11 and an interference member 12. The fixed bracket 11 defines a rotation hole, through which the rotating shaft 22 is inserted. The interference member 12 is sleeved over the portion of the rotating shaft 22 that does not extend into the rotation hole and is positioned between the fixed bracket 11 and the rotating body 21. The end surface of the interference member 12 proximal to the rotating body 21 forms a fixed interference surface, while the area of ​​the rotating body 21 that frictionally contacts the fixed interference surface forms a rotating interference surface.

[0046] It should be noted that the rotating body 21 is made of plastic, the interference member 12 is also made of plastic, the interference surface of the interference member 12 is a plastic friction surface, and the follower interference surface of the rotating body 21 is also a plastic friction surface.

[0047] Furthermore, the rotating body 21 is made of high-temperature resistant plastic material (plastic is a type of plastic material that softens when heated and solidifies when cooled, and has good processability, recyclability and versatility).

[0048] Furthermore, the fixed bracket 11 includes two opposing mounting walls, each with a rotation hole. A rotating body 21 is positioned between the two mounting walls, and a rotation shaft 22 is provided on each of the two side walls of the rotating body 21 that face the mounting walls. The interference member 12 is fixed to the side of the mounting wall adjacent to the rotating body 21. The rotation shaft 22 is sequentially inserted through the opening and rotation hole of the interference member 12.

[0049] On the one hand, the provision of the interference part 12 facilitates the replacement of the interference part 12 with friction loss, saving costs; on the other hand, the size of the interference part 12 can be designed according to actual needs to meet the friction contact area between the fixed interference surface and the rotating interference surface, ensuring the stopping and stopping effect of the rotating body 21 together with the lamp body when rotating.

[0050] Example 2

[0051] The rotating assembly 2 includes a rotating body 21 with a rotating hole defined therein, or a rotating sleeve disposed thereon, the rotating sleeve forming the rotating hole. The fixed assembly 1 includes a fixed bracket 11 and an interference member 12. The fixed bracket 11 is provided with a rotating shaft that extends through the rotating hole. The interference member 12 is sleeved over the section of the rotating shaft that does not extend into the rotating hole, and is located between the fixed bracket 11 and the rotating hole. The end surface of the interference member 12 near the rotating hole forms a fixed interference surface, and the area where the rotating body 21 (or rotating sleeve) frictionally contacts the fixed interference surface forms a rotating interference surface.

[0052] Example 3

[0053] The rotating assembly 2 includes a rotating body 21 and a rotating shaft fixed to the rotating body 21. The fixed assembly 1 includes a fixed bracket 11 and an interference member 12. The fixed bracket 11 defines a rotation hole. The interference member 12 is an annular structure that fits within the inner circumference of the rotation hole of the fixed bracket 11. The rotating shaft is inserted into the inner circumference of the interference member 12. The inner circumference of the interference member 12 forms a fixed interference surface, while the outer circumference of the rotating shaft forms a rotating interference surface.

[0054] Example 4

[0055] The rotating assembly 2 includes a rotating body 21, which has a rotating hole formed therein, or a rotating sleeve disposed thereon, which forms the rotating hole. The fixed assembly 1 includes a fixed bracket 11 and an interference member 12, which has a rotating shaft disposed thereon. The interference member 12 is an annular structure and is sleeved around the outer circumference of the rotating shaft on the fixed bracket 11. The interference member 12 is inserted into the inner circumference of the rotating hole. The outer circumference of the interference member 12 forms a fixed interference surface, while the inner circumference of the rotating hole forms a rotating interference surface.

[0056] In certain embodiments of the present application, friction particles are formed on the fixed interference surface.

[0057] In some embodiments, friction particles are formed on the rotational interference surface.

[0058] It should be noted that: ① friction particles are arranged only on the fixed interference surface; ② friction particles are arranged only on the rotating interference surface; ③ friction particles are arranged on both the fixed interference surface and the rotating interference surface. The friction particles are uniformly arranged on the fixed interference surface and / or the rotating interference surface.

[0059] As mentioned above, by setting friction particles, the friction coefficient between the fixed interference surface and the rotating interference surface can be guaranteed. The protruding structure formed by the friction particles can better make the fixed interference surface and the rotating interference surface "bite" together, ensuring a close contact effect between the two.

[0060] In certain embodiments of the present application, the friction particles have a particle size of 0.05 mm to 0.15 mm; for example, the particle size of the friction particles can be any one of 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.10 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, etc. Preferably, the particle size of the friction particles is 0.10 mm.

[0061] As described above, it is possible to ensure that the particle size of the friction particles is controlled within a reasonable range, and the friction coefficient between the fixed interference surface and the rotating interference surface is controlled within a moderate range, so that the rotation force is easy to control, and the user can easily rotate the rotating body 21, and the rotating body will not shake during the rotation process, and when the rotation stops, the rotating body 21 can be firmly fixed at the target angle that meets the requirements.

[0062] In certain embodiments of the present application, a lubricating layer is provided between the fixed interference surface and the rotating interference surface.

[0063] As mentioned above, by providing a lubricating oil layer, the friction loss between the fixed interference surface and the rotating interference surface can be reduced, avoiding excessive friction between the fixed interference surface and the rotating interference surface, causing the friction particles to be worn out and affecting the use effect of the lamp.

[0064] In some embodiments, the thickness of the lubricating layer is 0.05 mm to 0.15 mm; for example, the thickness of the lubricating oil layer can be any one of 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.10 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, etc. Preferably, the thickness of the lubricating oil layer is 0.10 mm.

[0065] As described above, the thickness of the lubricating oil layer can be controlled within a reasonable range, avoiding the lubricating oil layer being too thin to achieve the lubrication effect, and also avoiding the lubricating oil viscosity being too high due to the lubricating oil layer being too thick, which in turn increases the rotation damping and affects the rotation effect.

[0066] In some embodiments of the present application, the rotating body 21 of the rotating assembly 2 is a housing structure with an opening. The lamp includes a control board 4, which is fixed to the interior of the housing structure with the lamp body 3 and a heat dissipation port formed at the opening.

[0067] It should be noted that the control board 4 can be a PCB, and the lamp body 3 can be an LED. The control board 4 is electrically connected to the lamp body 3, which is fixed to the control board 4. Both are fixedly mounted within the rotating assembly 2. The control board 4 can be secured to the opening of the housing structure using a clamp; alternatively, the control panel can be welded to the opening of the housing structure.

[0068] The rotating body 21 is a cover structure with an opening, which facilitates the installation of the control board 4 and the lamp body 3 inside the cover structure; since the cover structure has an opening, when the control board 4 and the lamp body 3 are installed inside the cover structure, heat dissipation holes can be formed as long as the openings are not completely blocked. The formed heat dissipation holes facilitate the heat dissipation of the control board 4, which is beneficial to extending the service life of the lamp.

[0069] In some embodiments of the present application, the rotating body 21 includes a light-transmitting surface 211 , and a surrounding wall 212 is formed around the light-transmitting surface 211 .

[0070] It should be noted that the light-transmitting surface 211 can be provided on the sidewall opposite the opening of the housing structure; the light-transmitting surface 211 allows the light emitted by the lamp body 3 to diffuse to the outside world. The light-transmitting surface 211 can be made of a light-transmitting material such as organic glass, quartz glass, polypropylene, or polyester. The surrounding wall 212 can be made of an opaque material.

[0071] By setting a surrounding wall 212 around the light-transmitting surface 211, on the one hand, the light beam can be gathered to ensure the brightness of lighting and reading; on the other hand, the light-transmitting surface 211 can be safely protected to avoid friction loss, collision damage, etc. to the light-transmitting surface during use, which is beneficial to extending the service life of the lamp.

[0072] In summary, the present application further discloses a vehicle, which includes a cab and a reading light arranged in the cab, and the reading light is the lamp described above.

[0073] Since the vehicle of the present application includes the lamps described above, the beneficial effects brought about by the lamps to the vehicle can be found above and will not be repeated here.
