Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit trains, and in particular to a suspension device inside a rail transit train. Background Technology
[0002] Rail transit trains have become an important part of modern urban and regional transportation. With the acceleration of urbanization and the continuous growth of passenger numbers, the humanization, comfort, safety and space utilization efficiency of the train's interior facilities have become the focus of design and manufacturing. Among them, the suspension device inside the train is an indispensable auxiliary facility for placing items.
[0003] Currently, most suspension systems adopt a rigid fixed structure, that is, luggage racks made of metal or hard plastic are directly fixed to the internal frame of the train body by bolts, welding or integral molding. This connection method lacks a buffer structure, which may cause the impact to be directly applied to the suspension system, making it easy for placed items to fall off and causing people to bump into each other, which poses certain safety hazards. Due to the lack of multi-functional auxiliary structures, the passenger experience is poor. Utility Model Content

[0005] The technical solution of this utility model is: a suspension device inside a rail transit train, including a support and suspension assembly, a buffer and adjustment assembly connected to the support and suspension assembly, and a multi-functional extension assembly connected to the buffer and adjustment assembly;
[0006] The support and suspension assembly includes a side plate connected to the buffer and adjustment assembly, a support plate connected to the side plate, and a top plate connected to the support plate;
[0007] The buffer and adjustment assembly includes a protective shell connected to the top plate, a threaded seat connected to the top plate, and a connecting rod connected to the threaded seat.
[0008] The multi-functional expansion component includes corner protectors attached to the tray and LED lights attached to the tray.
[0009] Preferably, the support and suspension assembly further includes a first groove formed on the side plate, a support rod connected to the first groove, and a reinforcing rod connected to the support rod. The support rod is L-shaped and is slidably connected to the inside of the first groove by a slider.
[0010] Preferably, the buffer and adjustment assembly further includes a spring connected to the connecting rod, one end of the spring being connected to a threaded seat and the other end of the spring being connected to a support ring on the support plate.
[0011] Preferably, the buffer and adjustment assembly further includes a locking nut connected to the connecting rod and a protective sleeve connected to the locking nut, the protective sleeve being made of rubber material.
[0012] Preferably, the corner protector is located at the corner of the tray, the corner protector is made of high-density foam material, and the LED light is embedded in the side of the tray by a snap fastener.
[0013] Preferably, the multifunctional expansion component includes a second slide groove formed on the support rod and a hook connected to the second slide groove, wherein the hook is slidably connected to the inside of the second slide groove by a slider.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model integrates buffer and adjustment components, and uses a combination of threaded seat, connecting rod and spring to realize the adjustment of the height of the suspension device, so that it can adapt to different carriage interior structures and passenger height requirements. At the same time, through the dual shock absorption design of spring and rubber protective sleeve, it effectively absorbs the vibration and impact during train operation.
[0016] 2.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] A suspension device for rail transit trains, according to Figures 1-4 As shown, a suspension device inside a rail transit train includes a support and suspension assembly 1, a buffer and adjustment assembly 2 connected to the support and suspension assembly 1, and a multi-functional extension assembly 3 connected to the buffer and adjustment assembly 2.
[0024] The support and suspension assembly 1 includes a side plate 101 connected to the buffer and adjustment assembly 2, a support plate 105 connected to the side plate 101, and a top plate 106 connected to the support plate 105;
[0025] The buffer and adjustment assembly 2 includes a protective shell 201 connected to the top plate 106, a threaded seat 202 connected to the top plate 106, and a connecting rod 203 connected to the threaded seat 202.
[0026] The multi-functional expansion component 3 includes a corner protector 303 connected to the tray 105 and an LED light 304 connected to the tray 105.
[0027] according to Figure 2 The support and suspension assembly 1 also includes a first slide groove 102 formed on the side plate 101, a support rod 103 connected to the first slide groove 102, and a reinforcing rod 104 connected to the support rod 103. The support rod 103 is L-shaped and is slidably connected to the inside of the first slide groove 102 by a slider.
[0028] It should be noted that the "L"-shaped support rod 103 can provide more stable support for the support plate 105, and the reinforcing rod 104 can further enhance the structural rigidity of the support rod 103, prevent the support rod 103 from bending and deforming when bearing load, and ensure the stability and load-bearing capacity of the structure.
[0029] according to Figure 3 The buffer and adjustment assembly 2 also includes a spring 204 connected to the connecting rod 203. One end of the spring 204 is connected to the threaded seat 202, and the other end of the spring 204 is connected to the support ring on the support plate 105.
[0030] It should be noted that when an external impact force is applied to the support and suspension assembly 1, the spring 204 will undergo compression or stretching deformation to play a buffering role, reducing the damage caused by the impact to the entire structure. In addition, the spring 204 will provide a certain preload or support force in the static state, assisting the support rod 103 in bearing the load on it.
[0031] according to Figure 3 The buffer and adjustment assembly 2 also includes a locking nut 205 connected to the connecting rod 203 and a protective sleeve 206 connected to the locking nut 205. The protective sleeve 206 is made of rubber material.
[0032] It should be noted that the locking nut 205, through its threaded engagement with the connecting rod 203, can adjust the deformation of the spring 204, adjust the preload of the spring 204, and adjust the strength of the buffer and elastic support. The rubber material has good elasticity, which can provide a certain buffering effect, reduce the occurrence of collision accidents, and improve safety.
[0033] according to Figure 4 The corner protector 303 is located at the corner of the tray 105. The corner protector 303 is made of high-density foam material. The LED lighting lamp 304 is embedded in the side of the tray 105 by a buckle.
[0034] It is important to note that high-density foam materials have excellent cushioning properties, which can absorb impact energy and effectively prevent people from bumping into them. LED lighting can provide some illumination, enhance visibility, and prevent bumps.
[0035] according to Figure 4 The multi-functional extension component 3 includes a second slide groove 301 formed on the support rod 103 and a hook 302 connected to the second slide groove 301. The hook 302 is slidably connected to the inside of the second slide groove 301 by a slider.
[0036] It should be noted that the hook 302 can be used by passengers to hang small items such as handbags. The position of the hook 302 can be adjusted on the support rod 103 to accommodate the hanging needs of different items.
[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
