Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber windshield technology, specifically a vibration-damping rubber windshield for rail transit. Background Technology
[0002] Rubber windshields for rail transit are an important component of the end connection system of railway locomotives and rolling stock. They are mainly used to connect adjacent carriages to form a complete passage. They also have functions such as sealing, sound insulation, heat insulation, and buffering to adapt to the vibration and impact during vehicle operation and ensure that the vehicle can pass through curves, switches, etc. smoothly and safely.
[0003] Utility model patent application document with publication number "CN208559351 U" discloses a built-in rubber windshield for a railcar. A windshield is fixedly installed on the inner side of a square rubber frame, and a horizontal plate is fixedly installed on the top inner side of the square rubber frame. A crossbar is mounted on the side of the crossbar via two sets of rotating components. A sunshade cloth is wound around the crossbar, with one end of the sunshade cloth fixedly connected to the surface of the crossbar and the other end being free. An opening is provided on one side wall of the inner side of the square rubber frame, and one end of the crossbar extends into the opening and connects to a driven pulley. The driven pulley is connected to a driving pulley via a belt. The driving pulley is located at the bottom inside the opening, and an adjustment knob is fixedly installed on the outer side of the driving pulley. This utility model is easy and quick to install, saves time, and allows for convenient adjustment of the sunshade cloth position, thus better meeting user requirements.
[0004] The aforementioned document discloses the following defects in the built-in rubber windshields of railcars: the installation method of this technical solution is simply a snap-fit connection, which has limited ability to buffer vibrations. When vibrations are transmitted to the windshield, the windshield can only passively bear the vibration energy, lacking an effective buffering mechanism. Frequent vibrations will lead to a reduction in the service life of the windshield.
[0005] Therefore, it can be seen that the existing built-in rubber windshields of rail trains do not have a good shock absorption mechanism, and it is necessary to improve the existing shortcomings and provide a vibration-damping rubber windshield for rail transit. Utility Model Content
[0006] The purpose of this utility model is to provide a vibration-damping rubber windshield for rail transit, which solves the problem that the existing technology is just a simple snap-fit connection, which has limited ability to buffer vibration. When vibration is transmitted to the windshield, the windshield can only passively bear the vibration energy, lacking an effective buffering mechanism. Frequent vibration will lead to a reduction in the service life of the windshield.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model is a vibration-damping rubber windshield for rail transit, including a rubber frame. The rubber frame has insertion slots on both sides. A light-shielding mechanism is installed inside the rubber frame. Glass is fixedly installed inside the rubber frame. A shock-absorbing mechanism is fixedly installed on the outer surface of the rubber frame. The number of shock-absorbing mechanisms is fixed to four, and the four shock-absorbing mechanisms are distributed at the four corners of the rubber frame.
[0009] Furthermore, the shock-absorbing mechanism includes a positioning plate, which is fixedly installed on the outer surface of the rubber frame. A movable block is rotatably connected inside the positioning plate, and a fixed plate is fixedly installed at one end of the movable block.
[0010] Furthermore, a damping rod is fixedly installed on one side of the fixing plate.
[0011] Furthermore, a connecting plate is fixedly installed at one end of the damping rod, and a spring is sleeved on the outer surface of the damping rod. One end of the spring is connected to the outer surface of the fixed plate, and the other end of the fixed plate is connected to the outer surface of the connecting plate.
[0012] Furthermore, a mounting groove is provided on the side of the rubber frame away from the light-shielding mechanism, and a cleaning mechanism is installed inside the mounting groove.
[0013] Furthermore, the cleaning mechanism includes a diversion pipe, which is fixedly installed inside the mounting groove. Several sets of nozzles are fixedly installed on the lower surface of the diversion pipe. The nozzles extend to the inner surface of the rubber frame and are located on one side of the glass. A pump is fixedly installed inside the mounting groove. The output end of the pump is connected to the diversion pipe, and the input end of the pump extends to the outer surface of the rubber frame.
[0014] This utility model has the following beneficial effects:
[0015] (1) When vibration occurs during the operation of the rail transit vehicle, the vibration will be transmitted to the rubber frame. The damping mechanism at the four corners of the rubber frame will start to work. Since the positioning plate is fixed on the rubber frame, the vibration will cause the movable block to rotate inside the positioning plate. The fixed plate will be displaced with the rotation of the movable block. At this time, the damping rod and the spring sleeved on its outer surface will play a role. When the fixed plate is displaced, the spring will be compressed or stretched. The elastic potential energy of the spring is used to absorb and buffer the vibration energy. At the same time, the damping rod can control the extension and contraction speed of the spring to prevent the spring from over-extension and contraction and causing resonance and other adverse phenomena. This effectively reduces the impact of vibration on the rubber windshield, thereby reducing the impact of vibration generated during the operation of rail transit on the rubber windshield and extending the service life of the rubber windshield.
[0016] (2) When the glass needs to be cleaned, the pump installed inside the mounting groove is started. When the pump is working, it will draw the cleaning liquid from the storage box outside the rubber frame and then deliver the cleaning liquid to the distribution pipe through the output end. The distribution pipe distributes the cleaning liquid to several sets of nozzles. The nozzles spray the cleaning liquid onto one side of the glass, thereby cleaning and rinsing the glass, achieving the effect of easy cleaning of the glass and improving its practicality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4 As shown, this utility model is a vibration-damping rubber windshield for rail transit, including a rubber frame 1. Both sides of the rubber frame 1 are provided with insertion slots 101. A light-shielding mechanism 3 is installed inside the rubber frame 1. A glass 4 is fixedly installed inside the rubber frame 1. A shock-absorbing mechanism 5 is fixedly installed on the outer surface of the rubber frame 1. The number of shock-absorbing mechanisms 5 is fixed to four, and the four shock-absorbing mechanisms 5 are distributed at the four corners of the rubber frame 1.
[0027] The shock absorption mechanism 5 includes a positioning plate 501, which is fixedly installed on the outer surface of the rubber frame 1. A movable block 502 is rotatably connected inside the positioning plate 501, and a fixed plate 503 is fixedly installed at one end of the movable block 502.
[0028] A damping rod 504 is fixedly installed on one side of the fixed plate 503;
[0029] A connecting plate 505 is fixedly installed at one end of the damping rod 504, and a spring 506 is sleeved on the outer surface of the damping rod 504. One end of the spring 506 is connected to the outer surface of the fixing plate 503, and the other end of the fixing plate 503 is connected to the outer surface of the connecting plate 505.
[0030] When vibrations occur during the operation of rail transit vehicles, the vibrations are transmitted to the rubber frame 1. The damping mechanisms 5 at the four corners of the rubber frame 1 start to work. Since the positioning plate 501 is fixed to the rubber frame 1, the vibration will cause the movable block 502 to rotate inside the positioning plate 501. The fixed plate 503 will be displaced as the movable block 502 rotates. At this time, the damping rod 504 and the spring 506 sleeved on its outer surface play a role. When the fixed plate 503 is displaced, the spring 506 will be compressed or stretched. The elastic potential energy of the spring 506 is used to absorb and buffer the vibration energy. At the same time, the damping rod 504 can control the extension and contraction speed of the spring 506 to prevent the spring 506 from over-extension and contraction and causing resonance and other adverse phenomena. This effectively reduces the impact of vibration on the rubber windshield, thereby reducing the impact of vibration generated during rail transit operation on the rubber windshield and extending the service life of the rubber windshield.
[0031] A mounting groove 2 is provided on the side of the rubber frame 1 away from the light-shielding mechanism 3, and a cleaning mechanism 6 is installed inside the mounting groove 2;
[0032] The cleaning mechanism 6 includes a diversion pipe 601, which is fixedly installed inside the mounting groove 2. Several sets of nozzles 602 are fixedly installed on the lower surface of the diversion pipe 601. The nozzles 602 extend to the inner surface of the rubber frame 1 and are located on one side of the glass 4. A pump 603 is fixedly installed inside the mounting groove 2. The output end of the pump 603 is connected to the diversion pipe 601, and the input end of the pump 603 extends to the outer surface of the rubber frame 1.
[0033] When it is necessary to clean the glass 4, the pump 603 installed inside the mounting slot 2 is started. When the pump 603 is working, it draws cleaning fluid from the storage box outside the rubber frame 1, and then delivers the cleaning fluid to the distribution pipe 601 through the output end. The distribution pipe 601 distributes the cleaning fluid to several sets of nozzles 602. The nozzles 602 spray the cleaning fluid onto one side of the glass 4, thereby cleaning and rinsing the glass 4, achieving the effect of easy cleaning of the glass 4 and improving its practicality.
[0034] In use, first insert the clip into the installation position of the railcar through the insertion slot 101, and then connect the connecting plate 505 and the external connector together with the external bolts to complete the installation of the windshield.
[0035] When vibrations occur during the operation of rail transit vehicles, the vibrations are transmitted to the rubber frame 1. The damping mechanisms 5 at the four corners of the rubber frame 1 start to work. Since the positioning plate 501 is fixed to the rubber frame 1, the vibration will cause the movable block 502 to rotate inside the positioning plate 501. The fixed plate 503 will be displaced as the movable block 502 rotates. At this time, the damping rod 504 and the spring 506 sleeved on its outer surface play a role. When the fixed plate 503 is displaced, the spring 506 will be compressed or stretched. The elastic potential energy of the spring 506 is used to absorb and buffer the vibration energy. At the same time, the damping rod 504 can control the extension and contraction speed of the spring 506 to prevent the spring 506 from over-extension and contraction and causing resonance and other adverse phenomena. This effectively reduces the impact of vibration on the rubber windshield, thereby reducing the impact of vibration generated during rail transit operation on the rubber windshield and extending the service life of the rubber windshield.
[0036] When it is necessary to clean the glass 4, the pump 603 installed inside the mounting slot 2 is started. When the pump 603 is working, it draws cleaning fluid from the storage box outside the rubber frame 1, and then delivers the cleaning fluid to the distribution pipe 601 through the output end. The distribution pipe 601 distributes the cleaning fluid to several sets of nozzles 602. The nozzles 602 spray the cleaning fluid onto one side of the glass 4, thereby cleaning and rinsing the glass 4, achieving the effect of easy cleaning of the glass 4 and improving its practicality.

Clearly, many modifications and variations can be made based on the content of this specification.
