Description

Technical Field

[0001] The utility model relates to the technical field of rail transit vehicle-mounted power supplies, in particular to an emergency power supply for door control in rail transit. Background Art

[0002] Rail transit includes subway systems, light rail systems, monorail systems, modern trams, magnetic levitation systems, automatic guided rail systems and urban rapid rail systems. In special circumstances, more carriages will be added to increase the capacity of rail transit. Since rail trains need to control more automated equipment at the same time, receive more data and output more control instructions, most rail trains are driven by electricity as the main source of kinetic energy. Rail trains can complete the transmission of electricity through suspended power supply lines and pantographs during movement. However, in addition to this, rail trains also need electricity to maintain their basic operation. In special circumstances, the train doors cannot be opened normally, or the train doors are closed and clamp the passenger's hair or clothing. At this time, the doors cannot be opened during the movement. The start and braking of the train will cause a certain inertia to the passengers. Passengers whose hair is clamped are very dangerous. Or, due to an emergency, the power supply line of the train is abnormal, resulting in a lack of basic electricity required for lighting in the car. Passengers are also very dangerous when getting on and off the train in dimly lit areas. Therefore, how to solve the above-mentioned problems has become a difficult problem that needs to be solved urgently. Utility Model Content

It can be used as a power source for opening rail transit doors, and can also be used as a manually triggered emergency power source, effectively solving the problem of driving power source for key components in rail train emergency situations. During use, the L-shaped contact pins can be adjusted to align with strip grooves of different lengths according to different purposes. Strip grooves of different lengths correspond to different reset times and emergency power use times. If the associated equipment only needs to be powered on for a few seconds, the L-shaped contact pins can be aligned with the shortest strip grooves. If the associated equipment needs to be powered on for several minutes, the L-shaped contact pins can be aligned with the longest strip grooves.

[0012] (2) The elastic reset assembly can automatically reset the battery pack when the force of the conical pressing link is released, and can also provide a buffer for the battery pack when it is impacted. When the power supply assembly needs to be used for a long time, the conical pressing link can be manually locked and fixed by the locking limit assembly. The buffer decompression spring can enable the device to slowly reset after the pressing force is released.

[0013] (3) The annular groove can be easily rotated, and the time for the device to maintain operation can be selected by rotation. The bar groove corresponds to the maximum single pressing depth of the conical pressing link and the time required to reset the corresponding position. The rotating clamp is used to adjust the position, and the locking clamp can be fixed after the position selection is confirmed. The tightness of the locking clamp also determines the reset time of the corresponding component to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1-6As shown, a rail transit door control emergency power supply, its main body includes a power supply placement cabin 1, the two ends of the power supply placement cabin 1 are connected to the wiring panel 3 through an elastic reset component 2, the outside of the wiring panel 3 is provided with a wiring contact 4, the side of the wiring panel 3 is connected to the power terminal 6 through a cable 5, one side of the power supply placement cabin 1 is connected to a conical pressing link 8 through a slot 7, the side of the conical pressing link 8 is connected to a locking limit component 10 through a groove 9, and the conical end of the conical pressing link 8 is connected to a buffer decompression spring 11. The power supply placement cabin is a directional box. Under normal conditions, the conical pressing link does not contact the battery pack. By pressing The conical push-link connects the two battery packs together. The head of the conical push-link is made of metal and the tail is made of non-conductive material. In an emergency, such as when the train door cannot be opened, the conical push-link can be pressed to force the train door to open. When the door of the urban rail transit train during peak hours in the morning and evening is clamped by hair, clothes, or backpacks, the train door can be opened at a slight angle by adjusting the position of the locking limit component to the shortest groove. Secondly, when the train encounters a special situation and the power is cut off, the emergency power supply is not turned on in time. At this time, short-term lighting can be achieved by pressing the conical push-link. A power battery placement slot is provided on one side of the wiring panel.

[0025] The elastic reset component 2 is set to an L-shaped structure, and the other end of the elastic reset component 2 is connected to the inner wall of the power supply compartment 1 through a reset spring 12. Its purpose is to provide buffering protection for the battery when it is impacted by the conical pressing link. When the conical pressing link is pressed, the elastic reset component moves to both sides. When the force of the conical pressing link is released, the elastic reset component is reset together with the battery pack and the wiring panel under the action of the reset spring.

[0026] Power connection ports 13 are provided at both ends of the power terminal 6, and multiple power output transfer ports 14 are provided on the same side of the power terminal 6, the purpose of which is to ensure a stable output node that can withstand an instantaneous high current overload.

[0027] A spring guide groove 15 is provided at one conical end of the conical pressing link 8, and a pressing handle 16 is provided at the other end of the conical pressing link 8. The pressing handle can be an arc-shaped structure or a round pancake-shaped structure. Corresponding marks or scales can also be set on the side of the conical pressing link so that the operator can perform basic operations according to the marks.

[0028] The groove 9 includes an annular groove 17 and a strip groove 18 horizontal to the conical pressing link 8. There are multiple strip grooves 18 with different lengths. One end of the multiple strip grooves 18 is connected to the annular groove 17 respectively. The length of the shortest strip groove is directly related to the release area of ​​the battery pack at both ends of the conical pressing link. Secondly, it limits the protruding length of the conical pressing link. When the protruding length is shorter, the corresponding reset time is shorter.

[0029] A rotating clamp 19 and a locking clamp 20 are respectively provided on the outside of the locking limit assembly 10, and an L-shaped contact foot 21 is longitudinally arranged on the inside of the locking limit assembly 10. The rotating clamp and the locking clamp are assembled together through a groove, and locking and position adjustment are achieved by rotating left and right. The locking limit assembly can also be a disposable structure, that is, pressing the conical pressing link, the annular locking limit assembly collapses and falls off. At this time, the groove can be ignored. After use, a new locking limit assembly can be replaced. When the locking clamp is locked, the conical pressing link slowly resets or stops under the action of the buffer decompression spring. The conical pressing link can be manually locked and fixed through the locking limit assembly. The locking limit assembly can be semi-fixed on the outer wall of the power supply compartment and can only be rotated.

[0030] Directions:

[0031] During operation, under normal circumstances, the device selects the corresponding strip groove 18 through the L-shaped contact foot 21 according to the applicable field, and is basically fixed by the locking clamp 20. When an emergency occurs and the device needs to be used, the conical pressing link 8 can be forced to move inward at one end of the cone by repeatedly pressing or pressing hard once, and the side of the conical end squeezes the power battery pack to move toward both ends, thereby achieving circuit connection of the battery pack and power supply. If it is used for a short period of time, press it once, and the device can automatically reset under the action of the buffer decompression spring 11. If it needs to be used for a long time and maintain this state, it is necessary to manually lock and fix the conical pressing link 8 through the locking clamp 20 to limit its automatic reset. If it does not involve an emergency, the device can be locked and fixed by the locking clamp 20 in the normal state. When it needs to be used, manually rotate the locking clamp 20 to release the restraining force on the conical pressing link 8. At this time, the corresponding strip groove 18 is found again by rotating the clamp 19, and the circuit connection can be achieved by pressing the conical pressing link 8.

[0032] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
