Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to an air duct structure for a battery compartment of a battery swapping cabinet. Background Art

[0002] At present, with the development of society and the rapid development of the electric vehicle industry, including private electric vehicles, delivery electric vehicles, etc., the battery swapping cabinet, as a part of it, also plays an important role; since the battery and the charger have certain requirements for temperature, too low or too high temperature will affect the charging efficiency. In extreme cases, they may even stop working (for example, when the temperature is below minus ten degrees in the north, the charging efficiency will be extremely low). At present, the method is to set an air duct for the battery swapping cabinet to keep the battery compartment at a suitable charging temperature. However, when the existing battery swapping cabinet is heated through the air duct, all the battery compartments of the battery swapping cabinet are heated, and there are usually empty battery compartments in the battery swapping cabinet, which leads to heat loss and waste of energy. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides an air duct structure for a battery compartment of a battery swapping cabinet.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] An air duct structure for a battery compartment of a battery swapping cabinet, comprising a main air duct arranged on the back side of the battery swapping cabinet. Air inlet holes communicating with the main air duct are formed on the back surfaces of the battery compartments of the battery swapping cabinet. A heating device is installed at the lower part of the main air duct, and a plurality of closing plates respectively cooperating with the air inlet holes are installed in the main air duct; an anti-collision column extending into the battery compartment through the air inlet hole is fixed on the side of the closing plate facing the battery compartment, and a plurality of guiding columns are fixed on the side of the closing plate facing away from the battery compartment. The guiding columns pass through the back plate of the battery swapping cabinet and are slidably connected with the back plate. An elastic device is installed between the closing plate and the back plate.

[0006] Further improvement, the elastic device is a spring.

[0007] Further improvement, the spring is sleeved outside the guiding column.

[0008] Further improvement, the guiding column is a T-shaped column.

[0009] Further improvement, the diameter of the air inlet hole is larger than the diameter of the guiding column.

[0010] Further improvement, the heating device is a heater.

[0011] The beneficial effects of the utility model are as follows:

[0012] Through a special design, when there is a battery charging in the battery compartment, the air inlet hole communicating with the air duct is opened, so as to ensure that the temperature in the battery compartment is at a suitable temperature for charging. When there is no battery charging, the air inlet hole is closed to avoid waste of heat and improve energy utilization efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present utility model will be further described with reference to the accompanying drawings, but the content in the drawings does not constitute any limitation to the present utility model.

[0014] Figure 1 It is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to make the purpose, technical solutions and advantages of the utility model more clear, the present utility model will be further described in detail below with reference to the accompanying drawings and examples.

[0016] Embodiment 1

[0017] As Figure 1 shown, a battery compartment air duct structure for a battery swapping cabinet includes a main air duct 1, a battery compartment 2, an air inlet hole 3, a heating device 4, a sealing plate 5, an anti-collision column 6, a guiding column 7, a back plate 8 and a spring 9.

[0018] Among them, the main air duct 1 is located at the back side of the battery swapping cabinet, and the air inlet hole 3 is also located at the back side of the battery compartment 2 and communicates with the main air duct 1, so as to facilitate the hot air to enter the battery compartment through the air inlet hole 3 to heat the battery 10.

[0019] The sealing plate 5 is located in the main air duct 1, with one side connected to the anti-collision column 6 and the other end connected to a plurality of guiding columns 7. A spring 9 is sleeved outside the guiding column. When there is no battery in the battery compartment, the anti-collision column 6 extends into the battery compartment 2 through the air inlet hole 3, and the guiding column 7 passes through the back plate 8 of the battery swapping cabinet and is slidably connected to the back plate 8. In order to prevent falling, the guiding column 7 is preferably arranged in a T-shaped structure.

[0020] When the battery 10 is placed in the battery compartment, as Figure 1 shown, the battery 10 will squeeze the anti-collision column 6, causing the sealing plate 5 to open the air inlet hole 3, so that the hot air enters the battery compartment 2 to heat the battery and the battery compartment.

[0021] When the battery compartment is empty, under the action of the spring, the sealing plate 5 blocks the air inlet hole 3. Thereby preventing the hot air from entering the empty battery compartment to save heat energy.

[0022] The heating device 4 is preferably an electric heater.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
