[0039] In order to solve the problem in the prior art that the method of changing the shielding area not only causes harm to the staff but also increases the difficulty of operation for the staff, the present application provides a sunshade device.

[0040] like Figures 1 to 9As shown, the shading plate device is used to block the light source during the hot spot test, and the shading plate device includes a shading plate assembly 10 and a driving device 20. The shading plate assembly 10 includes a shell 11 and a shading plate 12. The driving device 20 is connected to the shading plate 12 to drive the shading plate 12 to move, thereby adjusting the shading area of ​​the light source by the shading plate assembly 10. Among them, the shading plate assembly 10 has a storage state and a shading state. When the shading plate assembly 10 is in the storage state, the shading plate 12 is located in the shell 11; when the shading plate assembly 10 is in the shading state, at least part of the shading plate 12 is driven to move outside the shell 11 by the driving device 20.

[0041] By applying the technical solution of this embodiment, the shielding plate assembly 10 has a storage state and a light shielding state. When the shielding plate assembly 10 is in the storage state, the shielding plate 12 is located in the housing 11; when the shielding plate assembly 10 is in the light shielding state, at least part of the shielding plate 12 is driven by the driving device 20 to move outside the housing 11. When the shielding area needs to be adjusted, the driving device 20 is started, and the driving device 20 can drive the shielding plate 12 connected thereto to move along the second direction, thereby adjusting the overall shielding area of ​​the shielding plate assembly 10 until the shielding area is adjusted to the required area.

[0042] Compared with the prior art that requires staff to enter the light source box multiple times to increase or decrease the blocking area, the shading plate device in this embodiment drives the shading plate 12 connected thereto to move through the driving device 20 to achieve automatic adjustment of the blocking area. There is no need for staff to frequently enter the light source box, thereby solving the problem in the prior art that the method of changing the blocking area not only causes harm to the staff but also increases the difficulty of operation for the staff, thereby reducing the difficulty of operation for the staff.

[0043] In this embodiment, there are multiple shielding plates 12, and any two adjacent shielding plates 12 are movably connected. The driving device 20 is drivingly connected to at least one shielding plate 12 to drive the shielding plate 12 to drive the remaining shielding plates 12 connected thereto to move; wherein, the multiple shielding plates 12 are spaced apart along a first direction, and each shielding plate 12 moves along a second direction, and the first direction and the second direction are arranged at an angle.

[0044] Specifically, when the shielding plate assembly 10 is in the storage state, all the shielding plates 12 are located in the housing 11; when the shielding plate assembly 10 is in the light shielding state, at least a portion of at least one shielding plate 12 is driven to move outside the housing 11 by the driving device 20. When it is necessary to adjust the shielding area, the driving device 20 is started, and the driving device 20 can drive the shielding plate 12 connected to it to move along the second direction, thereby adjusting the overall shielding area of ​​the shielding plate assembly 10. Since two adjacent shielding plates 12 are movably connected, when one shielding plate 12 moves to a preset position equivalent to another shielding plate 12, it can drive the other shielding plate 12 to move, and so on, thereby adjusting the shielding area of ​​multiple shielding plates 12 until the shielding area is adjusted to the required area.

[0045] Compared with the prior art which requires the staff to enter the light source box multiple times to increase or decrease the shielding area, the shading plate device in this embodiment drives the shielding plate 12 connected to it to move through the driving device 20, and then drives the other shielding plates 12 connected to it to move through the shielding plate 12, that is, two adjacent shielding plates 12 can be driven by one moving shielding plate 12 to move the other shielding plate 12, so as to realize automatic adjustment of the shielding area, without the need for the staff to frequently enter the light source box, thereby solving the problem in the prior art that the method of changing the shielding area not only causes harm to the staff but also increases the difficulty of operation for the staff, thereby reducing the difficulty of operation for the staff.

[0046] In this embodiment, there are three shielding plates 12, and the driving device 20 is drivingly connected to one shielding plate 12 to drive the shielding plate 12 to drive the other shielding plates 12 connected thereto to move.

[0047] It should be noted that the number of shielding plates 12 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of shielding plates 12 is two, four, five, or more.

[0048] In this embodiment, the first direction is the height direction of the shading plate device, the second direction is the horizontal direction, and the first direction and the second direction are arranged perpendicular to each other.

[0049] In other embodiments not shown in the drawings, there is only one shielding plate, and the driving device is drivingly connected to the shielding plate to drive the shielding plate to move, thereby adjusting the shielding area of ​​the shielding plate assembly for the light source.

[0050] like Fig. 9As shown, the sunshade device also includes a transmission structure 30, and the driving device 20 is connected to at least one sunshade 12 by driving through the transmission structure 30. The transmission structure 30 is at least one of a transmission chain, a conveyor belt, and a gear rack structure. In this way, the driving device is connected to the sunshade 12 by driving through the transmission structure 30, thereby improving the movement stability of the sunshade 12 and avoiding vibration or noise during the movement of the sunshade 12, which affects the user experience of the staff. At the same time, the above-mentioned setting makes the type selection of the transmission structure 30 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0051] In the present embodiment, the transmission structure 30 is a transmission chain, so that the structure of the transmission structure 30 is simpler, easier to process and realize, and the processing cost and difficulty of the sunshade device are reduced.

[0052] Specifically, the chain of the transmission chain is connected to a shielding plate 12, and the driving device 20 drives the driving sprocket of the transmission chain, and the driving sprocket drives the chain to move, and then drives the shielding plate 12 to move, so as to adjust the shielding area. If the above shielding area cannot meet the test requirements, the shielding plate 12 drives another shielding plate 12 adjacent to and connected to it to move until the shielding area meets the test requirements.

[0053] like Figures 1 to 8 As shown, the shielding plate assembly 10 also includes a matching assembly 13, which is arranged between two adjacent shielding plates 12, and the matching assembly 13 includes a first protrusion 131 and a protrusion group, and the protrusion group includes at least two second protrusions 132 arranged opposite to each other, and a limiting space 133 is formed between the at least two second protrusions 132, and the first protrusion 131 extends into the limiting space 133 and moves in the limiting space 133. Among them, one of the first protrusion 131 and the protrusion group is arranged on one shielding plate 12, and the other of the first protrusion 131 and the protrusion group is arranged on the other shielding plate 12. In this way, the two adjacent shielding plates 12 are connected by the matching assembly 13 to ensure that one shielding plate 12 can drive the other shielding plate 12 to move under the action of the matching assembly 13, thereby improving the adjustment diversity of the shielding area of ​​the shielding plate device and improving the structural stability of the shielding plate device. At the same time, the above-mentioned arrangement makes the setting position of the matching assembly 13 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0054] In this embodiment, the driving device 20 is drivingly connected to a shielding plate 12 located above, the first protrusion 131 is arranged on the shielding plate 12, and the protrusion group is arranged on another shielding plate 12 located below the shielding plate 12.

[0055] In other embodiments not shown in the drawings, the driving device is drivingly connected to an upper shielding plate, the convex portion group is arranged on the shielding plate 12, and the first convex portion is arranged on another shielding plate below the shielding plate.

[0056] Optionally, there is one matching component 13; or, there are multiple matching components 13, and at least one matching component 13 is arranged between each two adjacent shielding plates 12. In this way, the above arrangement, on the one hand, makes the number of matching components 13 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff; on the other hand, when there are multiple matching components 13, the above arrangement increases the matching area between the two adjacent shielding plates 12, thereby improving the matching stability of the two.

[0057] In this embodiment, a matching component 13 is disposed between two adjacent shading plates 12, thereby reducing the processing cost and difficulty of the shading plate device.

[0058] Optionally, there is one first convex portion 131; or, there are multiple first convex portions 131, and the multiple first convex portions 131 are arranged at intervals along the length direction of the shielding plate 12. In this way, the above arrangement, on the one hand, makes the number of the first convex portions 131 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff; on the other hand, when there are multiple first convex portions 131, the above arrangement increases the matching area between two adjacent shielding plates 12, thereby improving the matching stability between the two.

[0059] In this embodiment, each mating component 13 includes two first protrusions, and the two first protrusions are spaced apart along the length direction of the baffle plate 12. Each mating component 13 includes two protrusion groups, and the two protrusion groups are arranged one-to-one corresponding to the two first protrusions and spaced apart along the length direction of the baffle plate 12.

[0060] It should be noted that the number of the first protrusions in each matching component 13 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, each matching component 13 includes three, four, five, or more first protrusions.

[0061] It should be noted that the number of convex part groups in each matching component 13 is not limited to this, and can be adjusted according to working conditions and usage requirements. Optionally, each matching component 13 includes three, four, five, or more convex part groups.

[0062] In this embodiment, the protrusion group in each mating component 13 includes two second protrusions 132, and a limiting space 133 is formed between the two second protrusions 132. The first protrusion 131 extends into the limiting space 133 and moves in the limiting space 133. When the first protrusion 131 moves to the limit stop of the second protrusion 132 located at the opening of the shell 11, the two shielding plates 12 are mutually limited and matched. Afterwards, if the driving device 20 continues to drive the shielding plate 12 to move, the shielding plate 12 connected to the driving device 20 can drive the shielding plate 12 located below it to move, thereby adjusting the shielding area.

[0063] Optionally, the shielding plate assembly 10 further includes a guide assembly, which is disposed between two adjacent shielding plates 12, and the guide assembly includes a third protrusion and a recess, wherein the third protrusion extends into the recess and can slide along the extension direction of the recess. Among them, one of the third protrusion and the recess is disposed on one shielding plate 12, and the other of the third protrusion and the recess is disposed on the other shielding plate 12. In this way, among two adjacent shielding plates 12, when one shielding plate 12 moves relative to the other shielding plate 12, the above-mentioned setting of the guide assembly can guide the moving shielding plate 12 to ensure that the shielding plate 12 slides along a preset direction, further improving the movement stability of the shielding plate 12. At the same time, the above-mentioned setting makes the setting position of the guide assembly more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

In this way, the above arrangement makes the structural layout of the driving device 20, the heat shield 50 and the shield assembly 10 more reasonable and compact, thereby improving the space utilization rate of the sunshade device.

[0065] In this embodiment, the heat insulation plate 50 is used to protect the shielding plate assembly 10 to prevent the shielding plate assembly 10 from being overheated and affecting its normal use and service life.

[0066] Optionally, the heat insulation board 50 is a mica board; and / or the driving device 20 is a reduction motor.

[0067] In this embodiment, the size of the mica board is 3mm*55mm*80mm, which is used to prevent the temperature of the test battery cell from being too high and damaging the components on the mechanism.

[0068] like Figures 1 to 8As shown, there are two mating components 13, and the plurality of shielding plates 12 include a first shielding plate 121, a second shielding plate 122, and a third shielding plate 123.

The third shielding plate 123 is located below the second shielding plate 122, and the convex portion group of the second mating component 13 is arranged on the upper plate surface of the third shielding plate 123.

[0069] In this embodiment, the housing 11 is a U-shaped plate, and when the shielding plate assembly 10 is in the light shielding state, at least part of the shielding plate 12 passes through the opening of the U-shaped plate. In this way, when the shielding plate assembly 10 is in the storage state, all the shielding plates 12 are located in the U-shaped plate, so that the shielding plates 12 are protected by the U-shaped plate; when the shielding area needs to be adjusted, the driving device 20 drives the shielding plates 12 to pass through the opening of the U-shaped plate to shield the light source.

[0070] Optionally, the sunshade device further comprises a remote controller, which is connected to the driving device 20 by signal, so as to control the start and stop of the driving device 20 through the remote controller, thereby adjusting the shielding area of ​​the sunshade assembly 10 .

When the shielding plate assembly is in the storage state, all shielding plates are located inside the shell; when the shielding plate assembly is in the shading state, at least a portion of at least one shielding plate is driven to move outside the shell by a driving device. When the shielding area needs to be adjusted, the driving device is started, and the driving device can drive the shielding plate connected to it to move along the second direction, thereby adjusting the overall shielding area of ​​the shielding plate assembly. Since two adjacent shielding plates are movably connected, when one shielding plate moves to a preset position equivalent to another shielding plate, it can drive the other shielding plate to move, and so on, thereby adjusting the shielding area of ​​multiple shielding plates until the shielding area is adjusted to the required area.

[0076] Compared with the prior art that requires staff to enter the light source box multiple times to increase or decrease the shielding area, the shading plate device in the present application drives the shielding plate connected to it to move through the driving device, and then drives other shielding plates connected to it to move through the shielding plate, that is, two adjacent shielding plates can be driven by one moving shielding plate to move another shielding plate, so as to realize automatic adjustment of the shielding area without the need for staff to frequently enter the light source box, thereby solving the problem in the prior art that the method of changing the shielding area not only causes harm to the staff but also increases the difficulty of operation for the staff, thereby reducing the difficulty of operation for the staff.
