[0069] In view of this, the battery compartment mechanism provided by an embodiment of the present invention includes a battery compartment body 100, a compartment door 200 and a purge assembly; the battery compartment body 100 has a accommodating space 110 for accommodating batteries, and the compartment door 200 is rotatably connected to the open end of the battery compartment body 100 to open or close the accommodating space 110; the purge assembly includes a control component 310 and a plurality of dust blowing components 320, the plurality of dust blowing components 320 are arranged at intervals, and one end of each of the dust blowing components 320 extends into the side wall of the battery compartment body 100 opposite to the compartment door 200, and the other end is used to be fluidically connected to the original air source component 400 of the electric vehicle; the control component 310 is connected to the plurality of dust blowing components 320 to control the opening and closing of the plurality of dust blowing components 320.

[0070] Specifically, see Figure 1 The original air source component 400 of the electric vehicle refers to an air source component configured on the electric vehicle for providing gas to other components of the electric vehicle, which may be an air pump.

[0071] When cleaning the storage space 110 of the battery compartment mechanism, the door 200 is opened, and the control unit 310 controls the multiple dust blowing components 320 to open. The dust blowing components 320 spray the gas in the original gas source component 400 of the electric vehicle into the storage space 110, and blow impurities and dust out of the door 200 during the spraying process. Compared with the original manual cleaning method of blowing from the outside to the inside, the dust blowing component 320 automatically cleans the battery compartment body 100 and blows from the inside to the outside, which can effectively blow away the dust in the corners, improve the cleaning effect and efficiency, and reduce labor intensity.

[0072] The structure and shape of the battery compartment mechanism are described in detail below:

[0073] In an optional solution of the embodiment of the present invention, a dust blowing assembly 320 is installed on the bottom wall of the battery compartment body 100 .

[0074] Specifically, when cleaning the battery compartment body 100 , the dust blowing assembly 320 on the bottom wall of the battery compartment body 100 operates to blow up the dust in the battery compartment body 100 , and the dust blowing assembly 320 on the side wall of the battery compartment body 100 operates to discharge the dust in the battery compartment body 100 .

[0075] A dust blowing assembly 320 is installed on the bottom wall of the battery compartment body 100 , which is helpful to blow up the powder or impurities deposited on the bottom wall of the battery compartment body 100 , and then discharge them out of the compartment using the dust blowing assembly 320 on the side wall of the battery compartment body 100 .

[0076] In an optional solution of the embodiment of the present invention, the air outlet of the dust blowing assembly 320 on the side wall of at least one battery compartment body 100 is oriented in different directions.

[0077] Specifically, among the multiple dust blowing assemblies 320 on the side wall of the battery compartment body 100 opposite to the hatch 200, the air outlets of some dust blowing assemblies 320 are horizontally toward the hatch 200, and the air outlets of some dust blowing assemblies 320 are inclined downward toward the bottom wall of the battery compartment body 100, thereby achieving blowing in multiple directions and avoiding the accumulation of dust or impurities.

[0078] In an optional scheme of an embodiment of the present invention, the battery compartment body 100 is configured to be square, and the side wall of the battery compartment body 100 opposite to the hatch 200 is a closing plate 120. An arc-shaped guide surface is provided between the closing plate 120 and the side wall connected thereto. The arc-shaped guide surface is recessed in a direction away from the center of the accommodating space 110. The arc-shaped guide surface reduces the dead corners of the battery compartment body 100, thereby preventing dust and impurities from accumulating in the dead corners and being unable to be cleaned.

[0079] In an optional solution of the embodiment of the present invention, a plurality of dust blowing assemblies 320 are connected in parallel.

[0080] Specifically, multiple dust blowing assemblies 320 are arranged at intervals along the length direction of the battery compartment body 100; or, multiple dust blowing assemblies 320 are arranged at intervals along the height direction of the battery compartment body 100; or, multiple dust blowing assemblies 320 are arranged in N rows and M columns, that is, the dust blowing assemblies 320 are arranged in N rows along the height direction of the battery compartment body 100, and in M ​​columns along the length direction of the battery compartment body 100.

[0081] The dust blowing components 320 are connected in parallel, so that the multiple dust blowing components 320 work independently, thereby avoiding the problem that a certain dust blowing component 320 is damaged and the battery compartment cannot be cleaned.

[0082] In an optional scheme of an embodiment of the present invention, the purge assembly also includes an air cylinder 323, which is installed on the outside of the battery compartment body 100 and is connected to the original air source component 400 of the electric vehicle; the control component 310 is connected to the air cylinder 323, and multiple dust blowing components 320 are all connected to the air cylinder 323 through the air pipe 510.

[0083] Specifically, the control member 310 is configured as an operating handle or button, and is connected to the air cylinder 323 via the air pipe 510 ; the control member 310 is installed in the driving area, and the driver can open or close the air cylinder 323 by operating the control member 310 , thereby opening or closing the dust blowing assembly 320 .

[0084] The air storage cylinder 323 is controlled by the control member 310 , which is easy to operate and can realize the control of multiple dust blowing assemblies 320 at the same time.

[0085] In an optional scheme of an embodiment of the present invention, the dust blowing assembly 320 includes a dust blowing piece 321 and a straight through 322, one end of the straight through 322 is connected to the dust blowing piece 321, and the other end is connected to the air pipe 510; the straight through 322 is installed on the side wall of the battery compartment body 100 opposite to the compartment door 200, and a sealing member is provided around the outer periphery.

[0086] Specifically, the dust blowing member 321 is threadedly connected to the straight-through 322, and the straight-through 322 is fixed on the side wall of the battery compartment body 100, so that the dust blowing member 321 is fixed on the side wall of the battery compartment body 100; and the dust blowing member 321 is threadedly connected to the straight-through 322 to facilitate installation and removal of the dust blowing member 321. The sealing member is set as a sealing ring. Figure 4 and Figure 6 The air cylinder 323 is connected to the straight-through 322 through the air pipe 510 and the three-way quick-connect connector, and the operating handle or button in the driving area controls the exhaust of the air cylinder 323, so that the battery compartment body 100 is purged from the inside to the outside through the dust blowing member 321. Furthermore, the air pipe 510 and the three-way quick-connect plug 520 are fixed to the chassis bracket of the electric vehicle to ensure that the air pipe 510 will not be blocked.

[0087] The through hole 322 enables the dust blowing member 321 to be installed on the side wall of the battery compartment body 100 .

[0088] In an optional solution of the embodiment of the present invention, the dust blowing member 321 is configured as a porous blowing head, one end of the porous blowing head is provided with multiple air outlets, and the other end is connected to the straight-through 322 .

[0089] See also Figure 5 The porous blowing head is equipped with multiple air outlets to increase the air outlet volume and air outlet direction and enhance the cleaning effect.

[0090] In an optional solution of the embodiment of the present invention, the cross-sectional area of ​​the inner cavity of the dust blowing member 321 gradually decreases from an end close to the straight through hole 322 to an end away from the straight through hole 322 .

[0091] Specifically, the cross section of the inner cavity of the dust blowing member 321 can be set to be circular or square. In this embodiment, the cross section of the inner cavity of the dust blowing member 321 is set to be circular, and the diameter gradually decreases from one end close to the straight through 322 to the end away from the straight through 322.

[0092] The cross-sectional area of ​​the inner cavity of the dust blowing piece 321 gradually decreases from one end close to the straight through hole 322 to the end far from the straight through hole 322, thereby increasing the gas flow rate at the gas outlet of the dust blowing piece 321 and enhancing the cleaning effect.

[0093] In an optional solution of the embodiment of the present invention, when the dust blowing member 321 is in operation, at least one dust blowing member 321 swings.

[0094] Specifically, the swinging of the dust blowing member 321 means that the direction of the air outlet of the dust blowing member 321 changes.

[0095] The dust blowing member 321 swings to change the direction of the air outlet of the dust blowing member 321, thereby achieving multi-directional cleaning of the battery compartment body 100 and enhancing the cleaning effect.

[0096] In an optional scheme of an embodiment of the present invention, the swinging dust blowing part 321 includes a fixed section 3211, a swinging section 3212 and a third driving component, one end of the fixed section 3211 is connected to the straight through 322, and the other end is rotationally connected to the swinging section 3212, and the third driving component is connected to the swinging section 3212 to drive the swinging section 3212 to swing.

[0097] Specifically, see Figure 7 , the fixed section 3211 and the swing section 3212 are rotatably connected via a rotating shaft, the rotating shaft is perpendicular to the axis of the fixed section 3211, and the third driving assembly drives the swing section 3212 to swing around the axis of the rotating shaft. Furthermore, the rotating shaft is placed horizontally, and the third driving assembly drives the swing section 3212 to swing up and down around the rotating shaft, so as to realize the blowing of the accommodation space 110 from top to bottom or from bottom to top; it is worth noting that when the dust blowing member 321 is in the initial state, that is, when the third driving assembly does not drive the swing section 3212 to swing, the swing section 3212, under the action of its own gravity, the axis of the swing section 3212 gradually tilts downward from the end close to the fixed section 3211 to the end far away from the fixed section 3211, so that the air outlet of the swing section 3212 faces downward, so as to prevent dust or impurities from entering the air outlet and blocking the air outlet.

[0098] The third driving assembly is connected to the swing section 3212 so that the swing section 3212 of the dust blowing member 321 can swing when the dust blowing member 321 is in operation.

[0099] As an embodiment, the third driving assembly includes a driving plate 3214, a cylinder 3215 and a plurality of pull ropes 3216, the plurality of pull ropes 3216 are connected one by one to the swing sections 3212 of the plurality of dust blowing parts 321, and are all installed on the driving plate 3214; the telescopic rod of the cylinder 3215 is connected to the driving plate 3214 to drive the driving plate 3214 to move.

[0100] Specifically, see Figure 8 The driving plate 3214 is located on the back of the battery compartment body 100, one end of the stretch is connected to the driving plate 3214, and the other end passes through the battery compartment body 100 and is connected to the swing section 3212. The cylinder 3215 is installed on the back of the battery compartment body 100 to drive the driving plate 3214 to move away from the back of the battery compartment body 100 or towards the back of the battery compartment body 100. When the driving plate 3214 moves in the direction away from the back of the battery compartment body 100, the pull rope 3216 pulls the swing section 3212 to swing upward; when the driving plate 3214 moves in the direction close to the back of the battery compartment body 100, the swing section 3212 swings downward under its own gravity. The driving plate 3214 and the cylinder 3215 are both installed on the back of the battery compartment body 100 to avoid the driving plate 3214 and the cylinder 3215 forming a narrow gap in the accommodation space 110 that is inconvenient to clean. Furthermore, a guide rail is installed on the back of the battery compartment body 100, and the guide rail is perpendicular to the back of the battery compartment body 100; the guide rail is slidably connected to the drive plate 3214 to guide the movement direction of the drive plate 3214. It is worth noting that the cylinder 3215 is connected to the control part 310 signal. When the control part 310 starts the dust blowing part 321, the cylinder 3215 is started, and when the dust blowing part 321 is running, the swing section 3212 swings, and then the dust blowing part 321 blows the accommodating space 110 from top to bottom or from bottom to top, thereby improving the cleaning effect. Of course, the structure in which the cylinder 3215 uses a motor, or the motor cooperates with other transmission components to achieve linear drive, etc., should also be within the protection scope of the embodiments of the present invention.

[0101] The cylinder 3215 , the pull rope 3216 and the driving plate 3214 cooperate to drive the swing section 3212 to swing when the dust blowing member 321 is in operation.

[0102] As another embodiment, the third driving component includes a timer and a plurality of electromagnets 3217 , the swing section 3212 is magnetic, a plurality of electromagnet blocks are installed above the swing section 3212 , and the plurality of electromagnets 3217 are connected in series to the timer signal.

[0103] Specifically, the timer is used to control the on and off time of the electromagnet 3217.

[0127] The above-mentioned purge instruction is usually triggered by the user through the control panel or control component on the electric vehicle. After receiving the purge instruction, the control chip 600 determines to open the multiple dust blowing parts 321.

[0128] The specific method in which the control chip 600 controls the control component 310 to open the plurality of dust blowing components 321 may be to send an opening signal to the control component 310 , and after receiving the opening signal, the control component 310 turns on the switch of the air storage cylinder 323 .
