Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to a reading light for vehicle seats. Background Technology
[0002] When passengers ride rail vehicles, they sometimes need to work and sometimes need to read. This requires the installation of a reading light on the vehicle seat. However, current lighting fixtures are either too large and their structure is not suitable for installation on vehicle seats, or they can only adjust the angle of the lamp in one direction, which is difficult to meet the lighting needs of passengers when reading. Utility Model Content
[0003] In order to solve the above-mentioned problems of the prior art, the present invention provides a reading light for vehicle seats that can adjust the angle of the lamp body in both directions, which would be advantageous.
[0004] To achieve the above objectives, this utility model provides a reading light for vehicle seats, which includes a lamp body, a lamp holder, and a rotation adjustment mechanism connected between the two. The rotation adjustment mechanism is configured to include a parallel rotating shaft assembly rotatably connected to the lamp holder, and a vertical rotating shaft assembly with one end rotatably connected to the parallel rotating shaft assembly and the other end fixed to the lamp body, thereby enabling the lamp body to be angularly adjusted relative to the lamp holder in both vertical and horizontal directions.
[0005] Furthermore, the parallel rotating shaft assembly includes a parallel rotating shaft located between the lamp body and the lamp holder, a parallel rotating shaft mounting base fixed to the bottom of the lamp holder, a parallel limiting block, a butterfly spring, and a parallel locking nut. The parallel rotating shaft has a rotating shaft body, a lower locking part, and an upper connecting lug. The lower locking part is installed through the parallel rotating shaft mounting base and the aforementioned parallel limiting block, butterfly spring, and parallel locking nut are sequentially fixed to its bottom.
[0006] Furthermore, the parallel limiting block has a limiting notch, and the bottom of the parallel rotating shaft mounting base is provided with a limiting protrusion located within the range of the limiting notch. The limiting notch and the limiting protrusion are designed to restrict the rotation angle of the parallel rotating shaft within the range of 0-75º.
[0007] Furthermore, the lower locking part of the parallel shaft has a threaded position on its outer circumferential surface for screwing in a parallel locking nut and a flat position for fixing in a parallel limiting block.
[0008] Furthermore, the parallel shaft also has a through space that runs through its entire axial direction.
[0009] Furthermore, the vertical pivot assembly includes a vertical pivot, a vertical limiting block, a butterfly spring, a vertical locking nut, and a vertical pivot bracket. The vertical pivot is installed through the upper end connecting ear of the parallel pivot. The vertical limiting block is fixed to the vertical pivot within the upper connecting ear. The vertical pivot bracket is rotatably installed on the vertical pivot within the upper connecting ear at its upper end. The butterfly spring and the vertical locking nut are sequentially fixedly connected to the free end of the vertical pivot that passes through the upper connecting ear.
[0010] Furthermore, the vertical pivot bracket has a limiting protrusion on the side facing the vertical limiting block, and the vertical limiting block has a limiting notch that cooperates with the limiting protrusion, so that the rotation angle of the vertical pivot bracket can be limited to the range of 0-75º.
[0011] Furthermore, the free end of the vertical shaft has a threaded position on its outer circumferential surface for screwing in a vertical locking nut and a flat position for fixing in a vertical limiting block.
[0012] Furthermore, the vertical pivot bracket is fixed to the lamp body at its lower end with screws.
[0013] Furthermore, the lamp holder is constructed in the shape of a trough, and the lamp body is constructed in the shape of a cylinder, so that it can be at least partially stored in the lamp holder when not in use.
[0014] Compared with the prior art, this utility model has the following advantages: 1) By connecting the parallel rotating shaft assembly and the vertical rotating shaft assembly between the lamp body and the lamp holder, the lamp body can be controlled to rotate and adjust the lamp body angle in both the up-down (i.e., vertical direction) and left-right (i.e., parallel direction) directions, thereby achieving angle rotation adjustment of the lamp body within a certain angle range; 2) The rotation angle of the parallel rotating shaft axis is controlled by the parallel limiting block, and the damping force value of the parallel rotating shaft axis can be set by the butterfly spring and the parallel locking nut on the parallel rotating shaft, ensuring that the lamp body can maintain a stable position when it rotates around the parallel rotating shaft axis to a certain position; 3) The rotation angle of the vertical rotating shaft bracket around the vertical rotating shaft axis is controlled by the vertical limiting block, and the damping force value of the vertical rotating shaft axis can be set by the butterfly spring and the vertical locking nut, ensuring that the lamp body can maintain a stable position when it rotates around the vertical rotating shaft axis to a certain position.
[0015] These and other aspects of the present invention will be more clearly illustrated by referring to the embodiments described below. Attached Figure Description

[0025] The specific embodiments of this utility model will now be described in conjunction with the accompanying drawings.
[0026] like Figures 1 to 8 As shown, a vehicle seat reading light 100 according to a specific embodiment of the present invention includes a lamp body 101, a lamp holder 103, and a rotation adjustment mechanism 105 connected between the two. The rotation adjustment mechanism 105 is configured to include a parallel rotating shaft assembly 115 rotatably connected to the lamp holder 101 (see...). Figure 1 ), and a vertical shaft assembly 135, one end of which is rotatably connected to the parallel shaft assembly 115 and the other end of which is fixed to the lamp body 1 (see Figure 1 This allows the lamp body 101 to be positioned relative to the lamp holder 103 in the vertical direction (i.e., the up-down direction, see...). Figure 6 and refer to Figure 2 and Figure 5 ) and parallel direction (i.e., left and right direction, see Figure 7 and refer to Figure 2 , Figure 5 and Figure 6Adjust the angle on the top.
[0027] like Figure 3 and Figure 4 As shown, and with reference Figure 8 In this embodiment, the parallel rotating shaft 115 assembly includes a parallel rotating shaft 5 located between the lamp body 101 and the lamp holder 103, a parallel rotating shaft mounting base 4 fixed to the bottom of the lamp holder 103, a parallel limiting block 3, a butterfly spring 2, and a parallel locking nut 1. The parallel rotating shaft 5 has a rotating shaft body 50, a lower locking part 51, and an upper connecting lug 53. The lower locking part 51 is installed through the parallel rotating shaft mounting base 4, and the aforementioned parallel limiting block 3, butterfly spring 2, and parallel locking nut 1 are sequentially fixed at its bottom.
[0028] like Figure 4 As shown, the parallel limiting block 3 has a limiting notch 30, and the bottom of the parallel rotating shaft mounting base 4 is provided with a limiting protrusion (not shown) located within the range of the limiting notch 30. The limiting notch 30 and the limiting protrusion are configured to limit the rotation angle of the parallel rotating shaft 5 to the range of 0-75º. Of course, the size of the limiting notch 30 can be set according to actual needs to change the rotation angle range of the parallel rotating shaft 5.
[0029] For example Figure 3 and Figure 4 As shown, in this embodiment, the lower end locking portion 51 of the parallel shaft 5 has a threaded position 511 on its outer peripheral surface for screwing in the parallel locking nut 1 (see...). Figure 3 ) and the flat part 513 used to fix the parallel limiting block 3 (see Figure 4 It should be noted that the flat part 513 on the parallel rotating shaft 5 is designed to match the flat part 33 of the inner hole of the parallel limiting block 3 (see...). Figure 4 () Relatively fixed.
[0030] It should be understood that in this embodiment, the parallel shaft 5 is rotatable, the parallel limiting block 3 is used to limit the rotation angle of the parallel shaft 5, the butterfly spring 2 and the parallel fastening nut 1 are used to realize the damping force value, and these components rotate together around the parallel shaft mounting base 4 to control the rotation angle of the parallel shaft 115.
[0031] It should be noted that, as Figure 4 As shown, in this embodiment, the parallel shaft 5 also has a wire-passing space 52 extending along its entire axial direction, so that the wires led out from the lamp body 101 can exit the lamp holder 103 through the wire-passing space 52 of the parallel shaft 5. Figure 3 Arrow 17.
[0032] like Figure 3 and Figure 4 As shown, and with reference Figure 8In this embodiment, the vertical shaft assembly 135 includes a vertical shaft 6, a vertical limiting block 7, a butterfly spring 8, a vertical locking nut 9, and a vertical shaft bracket 10. The vertical shaft 6 is installed through the upper end connecting ear 53 of the parallel shaft 5. The vertical limiting block 7 is fixed to the vertical shaft 6 within the upper end connecting ear 53. The vertical shaft bracket 10 is rotatably installed on the vertical shaft 6 within the upper end connecting ear 53 at its upper end. The butterfly spring 8 and the vertical locking nut 9 are sequentially fixedly connected to the free end 60 of the vertical shaft 6 that passes through the upper end connecting ear 53.
[0033] like Figure 4 As shown, in this embodiment, the vertical shaft support 10 has a limiting protrusion (not shown) on its side facing the vertical limiting block 7. The vertical limiting block 7 has a limiting notch 70, which is configured to cooperate with the limiting protrusion and limit the rotation angle of the vertical shaft support 10 to the range of 0-75º. Of course, the size of the limiting notch 70 can be set according to actual needs to change the rotation angle range of the vertical shaft 6.
[0034] like Figure 3 and Figure 4 As shown, in this embodiment, the free end 60 of the vertical shaft 6 has a threaded position 69 on its outer circumferential surface for screwing in the vertical locking nut 9 (see...). Figure 3 ) and the flat part 67 for fixing the vertical limiting block 7 (see Figure 4 It should be noted that the flat part 67 on the vertical rotating shaft 6 is designed to match the flat part 77 of the inner hole of the vertical limiting block 7 (see...). Figure 4 () Relatively fixed.
[0035] For example Figure 3 As shown, in this embodiment, the vertical pivot bracket 10 is fixed to the lamp body 101 at its lower end by screws 11.
[0036] It should be understood that in this embodiment, the vertical shaft support 10 is also a rotating component. The vertical limiting block 7 is used to control the rotation angle of the vertical shaft support 10. The damping force is achieved by the butterfly spring 8 and the vertical locking nut 9. Together, they rotate around the vertical shaft 6 to achieve angular rotation in the vertical direction. In this embodiment, the angle adjustment of the vertical shaft assembly 135 is limited by the vertical limiting block 7 to restrict the maximum adjustment angle, while the damping force ensuring that it stops at the required position is achieved by the butterfly spring 8 and the vertical locking nut 9.
[0037] For example Figure 1As shown, in this embodiment, the lamp holder 103 is configured in a groove shape, and the lamp body 101 is configured in a cylindrical shape, so that when the reading lamp 100 is in a non-working state, the lamp body 101 is at least partially housed in the lamp holder 103. The lamp holder 103 is also provided with mounting holes 113, so that it can be mounted to a vehicle seat by fastening screws.
