Description

Technical Field

[0001] This application relates to the field of driver's cab headgear technology, and more specifically, to driver's cab headgear fixing and shock absorption optimization components. Background Technology

[0002] The driver's cab hood is the outer shell at the front of the driver's cab of a subway car or train, mainly used to protect the driver and provide necessary visibility. Driver's cab hoods are usually made of composite materials, such as carbon fiber reinforced polymer (CFRP). Currently, in the process of optimizing the design of driver's cab hoods, it is necessary to consider the convenience and stability of the driver's cab hood when it is installed with the car body.

[0003] In related technologies, for example, patent CN215883657U provides a novel headgear fixing device for EMU driver's cab. This device fixes an extension plate to the inner wall of the headgear body with mounting bolts, increasing the stability of the connection between the headgear body and the car body. A horizontal plate is inserted into the interior of the car body, and a strip-shaped limiting plate is welded to the inner wall of the car body. When the arc-shaped plate is inserted into the interior of the car body, the strip-shaped limiting plate is inserted into the strip-shaped limiting groove, thereby achieving the limiting function. At the same time, the horizontal plate is installed and fixed to the top of the car body with a third expansion bolt, which can achieve vertical limiting and fixing between the car body and the headgear body, preventing the headgear body from swaying with the car body due to wind resistance, and greatly increasing the stability of the connection between the headgear body and the car body.

[0004] While the existing technical solutions described above solve the problems mentioned in the background, symmetrical arc-shaped plates are provided on both sides of the horizontal plate and on the inner wall of the mounting frame. A strip-shaped limiting groove is provided on the convex side of the arc-shaped plate. The strip-shaped limiting plate inserted inside the strip-shaped limiting groove can limit the connection between the mounting frame and the vehicle body, increasing the stability of the connection between the headgear body and the vehicle body. Furthermore, sealing and shock-absorbing pads are fixed on both sides of the strip-shaped limiting groove and on the surface of the arc-shaped plate, increasing the sealing at the contact point between the arc-shaped plate and the vehicle body. However, this also increases the resistance when the driver's cab headgear drives the horizontal plate into the vehicle body, resulting in less convenient operation when the driver's cab headgear is docked with the vehicle body due to the resistance.

[0005] In view of this, we propose an optimized component for fixing and damping the driver's cab headgear. Utility Model Content

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] Reference Figures 1-5 This application discloses a driver's cab headgear fixing and shock absorption optimization component, including a fixing frame 1, a headgear mounting bracket 2, a top fixing plate 3, a side fixing plate 4, and a bottom support plate 5. A partition plate 11 is fixedly installed on the outer side of the fixing frame 1; the headgear mounting bracket 2 is detachably installed on one side of the fixing frame 1, and a shock absorber (not shown in the figure) is installed on the top of the headgear mounting bracket 2 for shock absorption of the driver's cab headgear 100 it supports; the top fixing plate 3 is vertically slidably installed on the side of the fixing frame 1 away from the headgear mounting bracket 2; the side fixing plate 4 is horizontally slidably installed on one side of the fixing frame 1, and the side fixing plate 4 is located at the bottom of the top fixing plate 3; wherein, a sealing damping device is fixedly installed on the top of the top fixing plate 3. Vibration damping pad A31 and sealing damping pad B41 are fixedly installed on the outer side of the side fixing plate 4. Both sealing damping pad A31 and sealing damping pad B41 are in contact with the inner side of the carriage 200. Bottom support plate 5 is fixedly installed at the bottom of the fixed frame 1 as a support structure for the horizontal sliding of the fixed frame 1. Horizontal mounting plates 51 are symmetrically fixed on both sides of the bottom of the bottom support plate 5. The horizontal mounting plates 51 are fixedly connected to the fixed frame 1. A longitudinal reinforcing plate 52 is fixedly installed between the two horizontal mounting plates 51. A T-shaped insertion hole 53 is opened on the inner side of the longitudinal reinforcing plate 52. A T-shaped support 201 is slidably inserted into the inner side of the T-shaped insertion hole 53. The T-shaped support 201 is located at the bottom of the inner side of the carriage 200.

[0037] When installing the driver's cab hood 100, firstly, a hood mounting bracket 2 is fixedly installed inside the driver's cab hood 100. At this time, the driver's cab hood 100 is fixedly installed on the outside of the fixed frame 1 through the connecting plates 21 at both ends of the hood mounting bracket 2, which facilitates the assembly of the fixed frame 1 and the driver's cab hood 100. Then, the side fixing plates 4 and the top fixing plates 3 are assembled with the fixed frame 1 one after the other. At this time, the side fixing plates 4 on both sides are close to each other, and the top fixing plate 3 moves away from the top of the fixed frame 1 under its own weight, which facilitates the subsequent docking of the driver's cab hood 100 with the carriage 200 through the top fixing plate 3 and the side fixing plates 4. During docking, the fixed frame 1 with the driver's cab hood 100 installed on the outside is moved closer to the carriage 200, so that the bottom support plate 5 at the bottom of the fixed frame 1 is located on the top of the T-shaped support 201. Then, the fixed frame 1 is pushed into the carriage 200, so that the bottom of the bottom support plate 5 is located on the longitudinal reinforcing plate 5. The T-shaped insertion hole 53 on the inner side of the bottom support plate 5 and the T-shaped support 201 are interlocked. The contact surfaces of the bottom support plate 5 and the T-shaped support 201 are surface treated to make the contact surfaces smooth and reduce sliding resistance, so as to ensure the stability of the fixed frame 1 during the sliding process and improve the installation accuracy of the bottom support plate 5 and the carriage 200. After docking, the bottom support plate 5 and the carriage 200 are fixed together first, and then the top fixing plate 3 and the side fixing plate 4 are fixed to the inner side of the carriage 200. The sealing and shock absorption pad A31 on the top of the top fixing plate 3 and the sealing and shock absorption pad B41 on the outside of the side fixing plate 4 ensure the sealing of the contact position with the carriage 200. The fixing installation method is at least one of bolt fixing and welding fixing. When the head cover mounting bracket 2 is installed with the driver's cab head cover 100, the shock absorption performance of the driver's cab head cover 100 during use can be optimized by adding a shock absorber (such as an air spring driver's cab shock absorber) between the two.

[0038] Reference Figure 2 and Figure 3 The headgear mounting bracket 2 is fixedly installed inside the driver's cab headgear 100. Both ends of the headgear mounting bracket 2 are fixedly provided with connecting plates 21, which are detachably installed on the outside of the fixed frame 1. The bottom of the headgear mounting bracket 2 is provided with a support plate 22, and right-angle plates 23 are symmetrically fixedly provided on both sides of the bottom of the support plate 22. The right-angle plates 23 are fixedly installed on the inside of the fixed frame 1.

[0039] When assembling the fixed frame 1 and the driver's cab head cover 100, the head cover mounting bracket 2 is positioned on top of the support plate 22. The support plate 22 is pre-fixed to the fixed frame 1 via the right-angle plate 23. At this time, the driver's cab head cover 100 can be supported by the support plate 22, so as to facilitate the fixed installation of the connecting plate 21 and the fixed frame 1, and improve the support strength of the driver's cab head cover 100.

[0040] Reference Figure 2 and Figure 5Both sides of the top of the fixed frame 1 are provided with longitudinal sliding grooves 12, and both sides of the fixed frame 1 are provided with transverse sliding grooves 13 symmetrically. A T-shaped slider A32 is fixedly installed on the outer side of the top fixed plate 3 corresponding to the longitudinal sliding groove 12, and a T-shaped slider B42 is fixedly installed on the outer side of the side fixed plate 4 corresponding to the transverse sliding groove 13. Mounting holes are provided on the inner sides of both the top fixed plate 3 and the side fixed plate 4. A hanging plate 33 is fixedly installed at the bottom of the top fixed plate 3. The side of the hanging plate 33 that is bent upward is located inside the driver's cab head cover 100. A baffle 101 is fixedly installed on the inner side of the driver's cab head cover 100 against the fixed frame 1.

[0041] When assembling the top fixing plate 3 onto the outside of the fixing frame 1, first pass the hanging plate 33 on the outside of the top fixing plate 3 through the inside of the fixing frame 1, then move the top fixing plate 3 horizontally to abut against the outside of the fixing frame 1. At this time, the T-shaped slider A32 on the outside of the top fixing plate 3 will abut against the outside of the fixing frame 1. Then lift the top fixing plate 3 upwards, so that the top fixing plate 3 drives the hanging plate 33 to abut against the top of the fixing frame 1. At this time, the top fixing plate 3 drives the T-shaped slider A32 to be located at the top of the longitudinal slide groove 12. Then release the support for the top fixing plate 3, so that the top fixing plate... 3. Relying on its own gravity, it slides down to the bottom of the longitudinal chute 12. At this time, the top fixing plate 3 drives the hanging plate 33 to be located below the baffle 101. When the top fixing plate 3 is fixedly installed with the top of the carriage 200, the top fixing plate 3 drives the hanging plate 33 to be fastened to the outside of the baffle 101, thereby limiting the driver's cab head cover 100 horizontally. In the vertical direction, it does not affect the driver's cab head cover 100 to perform shock absorption and buffering actions. Specifically, the surfaces of the baffle 101 and the hanging plate 33 are smooth, and the application of lubricating oil ensures that the two can slide vertically within the limiting range of the hanging plate 33.

[0042] Reference Figure 5 The top fixing plate 3 has wedge blocks A34 symmetrically fixed on both sides of its bottom, and the side fixing plate 4 has wedge blocks B43 fixed on its top corresponding to the wedge blocks A34.

[0043] By setting wedge blocks A34 on both sides of the bottom of the top fixing plate 3 to limit the side fixing plates 4 on both sides, the side fixing plates 4 are prevented from sliding horizontally after being installed on both sides of the fixing frame 1. During the movement of the fixing frame 1, the side fixing plates 4 drive the outer T-shaped sliders B42 to slide out of the interior of the transverse slide groove 13. After the top fixing plate 3 is fixedly installed on the top of the carriage 200, the limitation on the side fixing plates 4 is automatically released, so that the side fixing plates 4 can be fixedly connected to both sides of the carriage 200 to ensure the stability of the connection between the driver's cab hood 100 and the carriage 200. It is also more convenient to insert and connect the driver's cab hood 100 and the carriage 200. After the top fixing plate 3 is fixed, the bottom wedge block A34 is moved to the top of the wedge block B43. By setting a sealing gasket on the contact surface of the wedge block A34 and the wedge block B43, the top fixing plate 3 and the bottom side fixing plates 4 on both sides form a continuous structure, which improves the stability and sealing of the installation.

[0044] In summary, when using the driver's cab headgear fixing and shock absorption optimization component disclosed in this application, firstly, a headgear mounting bracket 2 is fixedly installed inside the driver's cab headgear 100. At this time, the driver's cab headgear 100 is fixedly installed on the outside of the fixing frame 1 through the connecting plates 21 at both ends of the headgear mounting bracket 2. Then, the driver's cab headgear 100 is assembled with the fixing frame 1 through the headgear mounting bracket 2. During assembly, the headgear mounting bracket 2 is positioned on top of the support plate 22. The support plate 22 is pre-fixed to the fixing frame 1 through the right-angle plate 23. At this time, the driver's cab headgear 100 can be supported by the support plate 22, so as to facilitate the fixed installation of the connecting plate 21 and the fixing frame 1, and improve the support strength of the driver's cab headgear 100. Then, the side fixing plate 4 is horizontally slidably assembled by cooperating with the transverse sliding groove 13 through the outer T-shaped slider B42. Finally, the top fixing plate 3 is connected to the outer T-shaped slider A32. The longitudinal slide groove 12 is used for vertical sliding assembly. After assembly, the side fixing plates 4 on both sides are pushed towards each other to reduce the space occupied on both sides. At this time, the top fixing plate 3 moves away from the top of the fixing frame 1 under its own weight and falls on the top of the side fixing plate 4. The top fixing plate 3 limits the side fixing plates 4 on both sides through the wedge blocks A34 on both sides of the bottom to prevent the side fixing plates 4 from sliding horizontally on both sides of the fixing frame 1. During the movement of the fixing frame 1, the side fixing plate 4 drives the outer T-shaped slider B42 to slide away from the interior of the transverse slide groove 13. After the top fixing plate 3 is fixedly installed on the top of the carriage 200, the limit on the side fixing plate 4 is automatically released, so that the side fixing plate 4 can be fixedly connected to both sides of the carriage 200 to ensure the stability of the connection between the driver's cab hood 100 and the carriage 200, and to make it more convenient to plug and connect the driver's cab hood 100 and the carriage 200.

[0045] When assembling the top fixing plate 3 with the fixing frame 1, the hanging plate 33 on the outside of the top fixing plate 3 is first passed through the inside of the fixing frame 1. Then, the top fixing plate 3 is moved horizontally to abut against the outside of the fixing frame 1. At this time, the T-shaped slider A32 on the outside of the top fixing plate 3 will resist the outside of the fixing frame 1. Then, the top fixing plate 3 is lifted upward, so that the top fixing plate 3 drives the hanging plate 33 to abut against the top of the fixing frame 1. At this time, the top fixing plate 3 drives the T-shaped slider A32 to be located at the top of the longitudinal slide groove 12. Then, the support for the top fixing plate 3 is released, so that the top fixing plate 3 slides down to the bottom of the longitudinal slide groove 12 by its own weight. At this time, the top fixing plate 3 drives the hanging plate 33 to be located below the baffle 101. When the top fixing plate 3 is fixedly installed with the top of the carriage 200, the top fixing plate 3 drives the hanging plate 33 to be fastened to the outside of the baffle 101, so that the top fixing plate 3 has a lateral reinforcement effect on the top of the driver's cab head cover 100 through the hanging plate 33.
