Description

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] The inventor of the present invention has discovered through research that the first snap-fit ​​structure and the second snap-fit ​​structure are directly installed on both sides of the lamp body of a rail vehicle, and are assembled with the rail vehicle compartment through the first snap-fit ​​structure and the second snap-fit ​​structure. Although directly connecting the lamp body to the rail vehicle compartment through the snap-fit ​​structure may have a simple and direct installation method, it will cause the lamp body to become loose, fall off, or be damaged due to external vibrations, impacts, and other factors over a long period of time; the continuous impact of vibrations will cause uneven force on the lamp body, damage to internal components, noise problems, etc., thereby affecting the overall stability and service life of the lamp. Therefore, in order to improve the stability of the lamp, reduce vibration damage, extend the service life, and improve safety, the present invention introduces a vibration reduction design in the lamp used for rail vehicles.

[0020] Specifically, the present invention provides a lamp, such as Figure 1 , Figure 2 and Fig.11 As shown, the lamp includes: a lamp body 1, a first clamping structure 2, a second clamping structure 3, an annular cavity vibration reduction structure 4 and an extension arm 5; the first clamping structure 2 is located on one side of the lamp body 1, and is used to be assembled with the side of the top 100 of the rail vehicle; the second clamping structure 3 is located on the other side of the lamp body 1, and is used to be assembled with the top 100 of the rail vehicle; the annular cavity vibration reduction structure 4 is arranged between the lamp body 1 and the first clamping structure 2; one end of the extension arm 5 is connected to the bottom of the lamp body 1, and the other end of the extension arm 5 is connected to the bottom of the second clamping structure 3, so as to form a U-shaped cavity 6 with an opening upward together with the lamp body 1 and the second clamping structure 3.

[0021] Specifically, the lamp body 1 is used to be installed at a corner of the top 100 of a rail vehicle, and in order to expand the lighting range of the lamp body 1, the lamp body 1 is arranged obliquely (such as Fig.11As shown). The first snap-fit ​​structure 2 and the second snap-fit ​​structure 3 are connected to the rail vehicle from both sides of the lamp body 1, respectively, wherein the first snap-fit ​​structure 2 is used to be assembled with the side of the top 100 of the rail vehicle, and the second snap-fit ​​structure 3 is used to be assembled with the top 100 of the rail vehicle. In the present invention, the annular cavity vibration-damping structure 4 is added between the lamp body 1 and the first snap-fit ​​structure 2, and the air or space in the annular cavity vibration-damping structure 4 can be used as a buffer layer to help absorb vibration or impact force, thereby reducing the transmission of vibration to the lamp body 1. The present invention also adds the extension arm 5 between the lamp body 1 and the second snap-fit ​​structure 3, and isolates and buffers the lamp body 1 from the second snap-fit ​​structure 3 through the U-shaped cavity 6 formed between the extension arm 5 and the second snap-fit ​​structure 3 and the lamp body 1, helping to absorb vibration or impact force, thereby reducing the transmission of vibration to the lamp body 1.

[0022] The upward opening design of the U-shaped cavity 6 enables the vibration to be reflected around the U-shaped cavity 6 after being transmitted through the top of the U-shaped cavity 6, thereby reducing the impact of the vibration. When the vibration is reflected in the U-shaped cavity 6, energy consumption will be generated, which is equivalent to converting part of the vibration energy into heat energy or consuming it through elastic deformation of the material, thereby reducing the impact of the vibration on the lamp.

[0023] The annular cavity vibration reduction structure 4 has an additional top portion relative to the U-shaped cavity 6. This is because the lamp body 1 is arranged obliquely at the corner of the top 100 of the rail vehicle, and when the rail vehicle vibrates, the side close to the rail vehicle vibrates more, and the vibration transmission of the side is more direct, which is more susceptible to external vibration, lateral impact or irregular vibration, and requires a stronger vibration reduction mechanism; while the side of the lamp body 1 close to the top 100 of the rail vehicle has relatively small vibration, and the vibration is usually more uniform, and the impact is relatively slight. Therefore: in the present invention, between the lamp body 1 and the first engaging structure 2 The annular cavity vibration reduction structure 4 is provided. While the annular cavity vibration reduction structure 4 performs buffering, its closed-loop structure wall can help reduce vibration and provide additional support, thereby effectively dispersing vibration and reducing impact on the lamp body 1; and the extension arm 5 is designed between the lamp body 1 and the second snap-fit ​​structure 3, so as to form the U-shaped cavity 6 between the lamp body 1 and the second snap-fit ​​structure 3, and the opening of the U-shaped cavity 6 is arranged upward. The U-shaped cavity 6 does not have a top, but can use more cavity space through an open design to further disperse vibration and enhance the vibration absorption effect.

[0024] It can be seen that in the present invention, a vibration-damping structure is added between the lamp body 1 and the first snap-fit ​​structure 2, and between the lamp body 1 and the second snap-fit ​​structure 3, so as to achieve isolation and buffering between the lamp body 1 and the first snap-fit ​​structure 2 and the second snap-fit ​​structure 3, thereby reducing vibration of the lamp body 1 and improving the stability of the overall assembly of the lamp. At the same time, based on the fact that when the lamp is installed at an angle at the corner of the top 100 of the rail vehicle, the vibration received by the lamp body 1 in the direction of the side wall 200 close to the rail vehicle is stronger, and the vibration received by the lamp body 1 in the direction of the top 100 of the rail vehicle is relatively weak, the present invention respectively arranges different vibration reduction structures between the lamp body 1 and the first clamping structure 2, and between the lamp body 1 and the second clamping structure 3, so that while the annular cavity vibration reduction structure 4 performs buffering, its closed-loop structure wall can help reduce vibration and provide additional support, thereby effectively dispersing vibration and reducing the impact on the lamp body 1; and the extension arm 5 is designed between the lamp body 1 and the second clamping structure 3, so as to form the U-shaped cavity 6 between the lamp body 1 and the second clamping structure 3, and the opening of the U-shaped cavity 6 is arranged upward, and the U-shaped cavity 6 does not have a top, but can use more cavity space through an open design to further disperse the vibration and enhance the vibration absorption effect.

[0025] In one embodiment of the present invention, the top of the annular cavity vibration damping structure 4 is detachably connected to the top 100 of the rail vehicle, and the bottom of the annular cavity vibration damping structure 4 is connected to the first engaging structure 2; Figure 1 As shown, a mounting opening 201 is provided at the bottom of the first engaging structure 2 , and the mounting opening 201 is used for assembling with the side of the top 100 of the rail vehicle.

[0026] Specifically, in a vibrating environment such as a rail car, the self-weight of the lamp body 1 can help maintain the stability of the lamp; when the first snap-fit ​​structure 2 is located at the bottom of the annular cavity vibration reduction structure 4, the weight of the lamp body 1 will naturally act downward and be directly transmitted to the first snap-fit ​​structure 2 at the bottom, thereby ensuring a stable connection between the lamp and the car. The self-weight of the lamp body 1 helps to resist external vibration or impact force and prevent the lamp from swinging or shifting. At the same time, in a vibrating environment, the weight of the lamp will act vertically downward, so in this embodiment, the installation port 201 is set at the bottom of the first snap-fit ​​structure 2, and the contact surface between the first snap-fit ​​structure 2 and the rail vehicle car can increase friction, ensure the firmness of the connection part, and further improve the stability of the lamp installation.

[0027] In an embodiment of the present invention, a horizontal distance between the first engaging structure 2 and the lamp body 1 is smaller than a horizontal distance between the second engaging structure 3 and the lamp body 1 .

[0028] Specifically, since the lamp body 1 is installed at an angle, the weight of the lamp body 1 is more concentrated near the first clamping structure 2, and therefore, the first clamping structure 2 is closer to the lamp body 1. A relatively long extension arm 5 is arranged between the second clamping structure 3 and the lamp body 1, so that the second clamping structure 3 is relatively far away from the lamp body 1, so that the extension arm 5 can not only provide a vibration reduction effect for the lamp body 1, but also provide installation space for other parts, such as providing installation space for the handrail 300 in the interior of the rail vehicle, that is, one end of the handrail 300 is assembled on the ground of the rail vehicle, and the other end is installed in cooperation with the extension arm 5.

[0029] In one embodiment of the present invention, the tops of the lamp body 1, the annular cavity vibration reduction structure 4 and the second clamping structure 3 are all flush and installed in coordination with the top 100 of the rail vehicle, thereby increasing the contact area between the lamp and the rail vehicle and further improving the stability of the lamp when installed in the rail vehicle. Fig.11 As shown in FIG. 4 ), the second engaging structure 3 is installed in cooperation with the assembly position 400. Therefore, in this embodiment, since the tops of the lamp body 1, the annular cavity vibration reduction structure 4 and the second engaging structure 3 are all installed in cooperation with the top 100 of the rail vehicle, and the vibration of the top 100 of the rail vehicle is relatively small, the contact area between the lamp and the rail vehicle is as large as possible, while the vibration affected by the rail vehicle is as small as possible, further improving the stability of the lamp installed in the rail vehicle.

[0030] like Figure 3 As shown, the lamp also includes a plurality of multi-stage damping vibration-damping bodies 7, which are arranged in the annular cavity vibration-damping structure 4 and are arranged in an array. The multi-stage damping vibration-damping body 7 includes: a flexible vibration-damping layer 701, an elastic vibration-damping layer 702 and a liquid damping layer 703; the flexible vibration-damping layer 701 is in contact with the bottom of the annular cavity vibration-damping structure 4, the elastic vibration-damping layer 702 is arranged on the top of the flexible vibration-damping layer 701, and the liquid damping layer 703 is arranged on the top of the elastic vibration-damping layer 702 and in contact with the top of the annular cavity vibration-damping structure 4.

[0031] Specifically, since the vibration generated by the side wall 200 of the rail vehicle is greater during the rapid travel of the rail vehicle, the flexible vibration reduction layer 701, the elastic vibration reduction layer 702 and the liquid damping layer 703 in this embodiment are arranged in sequence from bottom to top; the flexible vibration reduction layer 701 uses flexible materials such as rubber, silicone, polyurethane, etc., as the first vibration reduction layer, it can quickly absorb the initial impact force and reduce the vibration transmission to the next stage. The elastic vibration reduction layer 702 includes a plurality of springs, and the plurality of spring arrays are arranged, and the vibration reduction effect of the elastic vibration reduction layer 702 is adjusted by selecting a plurality of spring hardnesses to adapt to different loads and vibration intensities. The liquid damping layer 703 uses liquid to absorb rapid vibrations and further consumes vibration energy through dispersed liquid conduction. The liquid damping layer 703 can be made of materials such as silicone oil and / or polyurethane liquid.

[0032] The multi-stage damping vibration isolating body 7 is cylindrical, and the flexible vibration isolating layer 701, the elastic vibration isolating layer 702 and the liquid damping layer 703 are arranged in sequence from bottom to top along the axial direction. The cylindrical structure of the multi-stage damping vibration isolating body 7 has good symmetry, so that under the action of vibration or impact, the force of the multi-stage damping vibration isolating body 7 can be evenly distributed; no matter from which direction the vibration or impact force is transmitted, the cylindrical structure can effectively disperse it, reduce local stress concentration, and thus reduce the risk of structural damage.

[0033] like Figure 4-Figure 8 As shown, the lamp body 1 includes a mounting frame 101, a rotating shaft 102, a light source mounting plate 103, a protective cover bracket 104, a light source 105 and a plurality of protective covers 106; one side of the mounting frame 101 is connected to the annular cavity vibration reduction structure 4, and the other side is connected to the extension arm 5; the bottom of the mounting frame 101 is provided with an assembly port 8 (such as Figure 2 and Figure 4 As shown); the rotating shaft 102 is located in the assembly opening 8 and is detachably connected to the mounting frame 101; one side of the light source mounting plate 103 is used to be detachably connected to the mounting frame 101, and the other side of the light source mounting plate 103 is detachably connected to the rotating shaft 102, and can be rotated relative to the rotating shaft 102 to open and close the assembly opening 8; the protective cover bracket 104 is located below the light source mounting plate 103; one side of the protective cover bracket 104 is rotatably connected to the rotating shaft 102, and the other side is detachably connected to the light source mounting plate 103 and the mounting frame 101 respectively; the protective cover bracket 104 and the light source mounting plate 103 enclose a accommodating space 9 (as shown Figure 1 The protective cover bracket 104 is provided with a plurality of protective cover installation positions 10 along the length direction (as shown); Figure 6As shown); the light source 105 is arranged on the light source mounting plate 103 and is located in the accommodating space 9; a plurality of protective covers 106 are matched with the protective cover mounting positions 10 in a one-to-one correspondence.

[0034] Specifically, the mounting frame 101 is used to respectively engage with the annular cavity vibration reduction structure 4, the extension arm 5, the light source mounting plate 103, the rotating shaft 102 and the protective cover bracket 104. The mounting frame 101 has a receiving space 11 and the assembly port 8. The light source mounting plate 103 and the protective cover bracket 104 are both rotatably connected with the rotating shaft 102, so that when the light source mounting plate 103 and the protective cover bracket 104 are synchronously and unidirectionally rotated relative to the rotating shaft 102, the light source mounting plate 103, the light source 105, the protective cover bracket 104 and the protective cover 106 can form an integral rotation, thereby opening and closing the assembly port 8. When the assembly port 8 is closed, the light source mounting plate 103 is located in the receiving space 11.

[0035] A plurality of protective covers 106 are sequentially arranged along the length direction of the protective cover bracket 104, that is, a plurality of protective covers 106 are sequentially arranged along the length direction of the rail vehicle. The same side of the light source mounting plate 103 and the protective cover bracket 104 can rotate relative to the rotating shaft 102, and the other side of both can be detachably connected to the mounting bracket 101, so as to position the lamp body 1 in a state where the assembly port 8 is closed. The light source 105 is arranged on the light source mounting plate 103 and is arranged toward the protective cover 106 so as to emit light from the protective cover 106.

[0036] The protective cover bracket 104 is also provided with a light-transmitting hole 12 (such as Figure 4 As shown in FIG. 1 ), at least a portion of the protective cover 106 corresponds to the light-transmitting hole 12, so that a portion of the protective cover 106 can be exposed through the light-transmitting hole 12 and realize the emission of light. Figure 4 , Figure 5 and Figure 6 As shown, the mounting frame 101, the light source mounting plate 103 and the protective cover bracket 104 are all provided with a plurality of C-shaped hanging rings 12, and the plurality of C-shaped hanging rings 12 are arranged in sequence along the length direction of the protective cover bracket 104 (i.e., the length direction of the rail vehicle); the C-shaped hanging rings 12 are sleeved on the periphery of the rotating shaft 102, thereby providing installation connection between the rotating shaft 102 and the mounting frame 101, the light source mounting plate 103 and the protective cover bracket 104, and providing relative rotation of the light source mounting plate 103 and the protective cover bracket 104 relative to the rotating shaft 102.

Fig. 9 As shown, the first epitaxial plate 14 is located below the inner buckle plate 13 and fits with the inner buckle plate 13, and the second epitaxial plate 15 is located below the first epitaxial plate 14 and fits with the first epitaxial plate 14. The first epitaxial plate 14, the second epitaxial plate 15 and the inner buckle plate 13 are detachably connected to each other, so that the assembly port 8 can be closed.

[0038] In one implementation of this embodiment, Figure 6 and Figure 8 As shown, the second extension plate 15 is provided with a slot 16; Figure 5 and Fig. 9 As shown, the first extension plate 14 is provided with a clamping protrusion 17, and the clamping protrusion 17 cooperates with the clamping groove 16, so that the first extension plate 14 and the second extension plate 15 are combined into a whole, so that when the connection between the inner buckle plate 13 and the first extension plate 14 and the second extension plate 15 is disassembled, the light source mounting plate 103 and the protective cover bracket 104 can form a whole and rotate around the rotating shaft 102, so as to open the assembly port 8. At the same time, the clamping protrusion 17 can be pulled out from the clamping groove 16 under the action of external force, so as to separate the light source mounting plate 103 from the protective cover bracket 104, so as to maintain or replace the light source 105 or other parts in the accommodating space 9.

[0039] In one embodiment of the present invention, Figure 4 As shown, a plurality of through holes 18 are provided on the top of the mounting frame 101 , and the through holes 18 correspond to the light source mounting plate 103 ; when the assembly opening 8 is opened, the assembly opening 8 is communicated with the through holes 18 .

[0040] Specifically, when the assembly port 8 is closed, a portion of the lamp body 1 can be exposed above the mounting plate through the through hole 18, thereby improving the heat dissipation capacity of the light source 105. When the assembly port 8 is opened, the components on the top of the rail vehicle can be exposed through the through hole 18 and the assembly port 8 in sequence, so as to facilitate maintenance by the staff.

[0041] like Figure 6 and Figure 7 As shown, the lamp also includes: a positioning bar 19, a sliding bar 20 and a gasket 21; the positioning bar 19 is located in the accommodating space 9, and is arranged on the protective cover bracket 104 near the rotating shaft 102; a mounting slide 22 is arranged on the side of the positioning bar 19 near the light source mounting plate 103; the sliding bar 20 cooperates with the mounting slide 22; the gasket 21 is arranged on the sliding bar 20, and is used to fit with the light source mounting plate 103.
