[0030] Techniques, methods, and systems known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered part of the description of the application.

[0031] Embodiment one: as shown, only one of the embodiments of the present application, a battery heat preservation structure on a platform door stand column, comprising a stand column body 1 and a battery box 2, the stand column body 1 comprises two substantially parallel side plates 12 and a main plate 11 for connecting the two side plates 12; the battery box 2 is at least partially located between the two side plates 12; the battery box 2 comprises a first box body 21 and a second box body 22 arranged on the side of the first box body 21 away from the main plate 11, the inside of the first box body 21 is provided with a first battery for powering the platform door lifting, and the inner wall of the first box body 21 is provided with an electric heating film, and the inside of the second box body 22 is provided with a second battery for powering the electric heating film. Figs. 1 to 3

[0032] In the present application, the stand column body 1 is provided with a platform door lifting structure, which can be a lifting plate or a lifting rope, and the lifting drive of the platform door lifting structure is powered by the battery in the battery box 2. When the platform door lifting structure is raised, the platform door is opened, and vice versa. When the platform door lifting structure is lowered, the platform door is closed. The stand column body 1 comprises two substantially parallel side plates 12 and a main plate 11 for connecting the two side plates 12, so that the stand column body 1 forms a C-shaped structure, and the battery box 2 is installed in the C-shaped structure. The battery box 2 insulates the battery, and the stand column body 1 also insulates the battery box 2, so that even if the stand column body 1 is located in an open platform, the temperature of the battery in the battery box 2 will not drop too fast, and the platform door can be opened and closed stably and safely.

[0033] Further, in the structure of the battery box 2, the battery box 2 comprises a first box body 21 and a second box body 22 arranged on the side of the first box body 21 away from the main plate 11, and the inside of the first box body 21 is provided with a first battery for powering the platform door lifting, that is, the first battery is the power drive for lifting the platform door lifting structure.

[0034] Here, the second box body 22 is equivalent to being arranged on the side of the first box body 21 close to the C-shaped opening direction of the stand column body 1, further blocking the heat dissipation of the first box body 21 in this direction, so that the heat preservation effect of the first battery in the first box body 21 is better.

[0035] ​Generally, when the temperature on the platform is not extremely low and the interval between trains is not too long (about half an hour for a train to enter and leave the station), the first battery is powered once every interval, and the first battery itself generates heat to warm the battery box 2, and the battery box 2, the second box 22 and the C-shaped column body 1 can keep the first battery warm, so that the first battery does not cool down to the point where it cannot output when the next train enters the station.

[0036] In special cases, when the temperature on the platform is extremely low or the train interval is long, or even during the night when the high-speed rail is not in operation, the battery box 2, the second box 22 and the C-shaped column body 1 have poor insulation effect on the first battery. At this time, the inner side wall of the first box 21 is provided with an electric heating film, which can heat the first battery in the first box 21 after being started, and the battery box 2, the second box 22 and the C-shaped column body 1 can block the heat generated by the electric heating film from escaping to keep the first battery warm.

[0037] In addition, the second box 22 is provided with a second battery for powering the electric heating film. When the second battery is used to power the electric heating film, the second battery itself will warm up, so that the second box 22 can further keep the first box 21 warm.

[0038] In actual use, the first battery and the second battery need to be charged intermittently. The charging strategy is: the first battery is charged first until the first battery is not less than the preset value, then the second battery is charged until the second battery is full, and then the first battery is charged again until it is full. The reason is that the first battery with a preset amount of electricity can ensure that the platform door can be normally opened, and the second battery is fully charged to ensure that the first battery is kept warm for the maximum time.

[0039] Of course, if the high-speed rail is not in operation for a long time at night and the platform is extremely cold, the first battery can also stop warming until the first train enters the station in the morning. The second battery powers the electric heating film to warm up and keep the first battery warm.

[0040] Embodiment two, still as Figs. 1 to 4 shown, is only one embodiment of the present utility model, based on embodiment one, the battery warming structure on the platform door column of the present utility model, the surface of the main plate 11 and the side plate 12 is provided with a thermal insulation coating, and the column body 1 further warms the battery box 1.

[0041] In the utility model, the side plate 12 is provided with the protection plate 13 away from one end of the main plate 11, at least a part of the battery box 2 is located between the main plate 11 and the protection plate 13, that is, the C-shaped structure opening of the stand column main body 1 is closed, that is, the rear of the battery box 2 is further blocked, which can prevent foreign matters from entering the battery box 2 and further insulate the battery box 2.

[0042] As an embodiment of the utility model, the first box body 21 is provided with a temperature sensor 23 away from one side of the main plate 11, the temperature sensor 23 is electrically connected with a controller, and the controller is electrically connected with the electric heating film.Although the battery box 2, the second box body 22 and the C-shaped stand column main body 1 insulate the first battery, the first battery will still be slowly cooled down as the temperature drops or the first battery stops working for a long time (that is, the train interval is long). Once the temperature sensor 23 senses that the temperature of the first box body 21 drops to the preset temperature value, the controller immediately drives the second battery to supply power to the electric heating film.

[0043] Preferably, the number of temperature sensors 23 is multiple, and the multiple temperature sensors 23 are distributed on the surface of the first box body 21, so that the multiple temperature sensors 23 simultaneously monitor the temperature of the first box body 21, and the monitoring effect is more accurate.

[0045] The motor 31 and the driving shaft 32 are located on the upper surface of the battery box 2, and the counterweight 4 is in contact with the lower surface of the battery box 2 when the counterweight 4 is located at the upper limit position. When the first battery is cooled down under the influence of external low temperature, the stand door is closed after the train departs, and at this time, the counterweight 4 is located at the upper limit position, and the counterweight 4 is in close contact with the lower surface of the battery box 2. The motor 31, the driving shaft 32 and the counterweight 4 also appropriately block the battery box 2, thereby achieving the insulation effect. At the same time, the counterweight 4, the motor 31 and the driving shaft 32 can also be heated when the electric heating film works.

[0046] In the utility model, the number of the second box 22 is two, and the temperature sensor 23 is located between the two second boxes 22, so that the temperature sensor 23 is away from the protective plate 13 by a certain distance and is not easily affected by the external temperature, and the reading of the temperature sensor 23 can better represent the temperature of the first box 21.

[0047] Meanwhile, the chain between the driving shaft 32 and the counterweight 4 is also partially located between the two second boxes 22, and the two second boxes 22 can limit the chain.

[0048] In the utility model, the battery box 2 is provided with a mounting protrusion 24 on the side, the side plate 12 is provided with a mounting groove 121 for conveniently inserting the mounting protrusion 24, and the battery box 2 is convenient to install; the mounting protrusion 24 is a heat insulation member; the second box 22 is a heat insulation member, and the first box 21 is further heat-insulated.
