In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The panel assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 3As shown, the panel assembly 100 according to the embodiment of the utility model comprises a panel body 1, a push plate assembly 2, a compression insulation member (not shown in the figure) and a driving mechanism 3. The panel body 1 has a receiving cavity 11, the push plate assembly 2 is movably disposed in the receiving cavity 11 and extends along a first direction, the push plate assembly 2 divides the receiving cavity 11 into a filling area 111 and a power area 112 along a second direction, the compression insulation member fills the filling area 111, the driving mechanism 3 is located in the power area 112 and connected to the panel body 1, and is used to drive the push plate assembly 2 to move along the second direction to change the area of ​​the filling area 111 and the power area 112, and the first direction and the second direction are perpendicular.

[0032] It can be understood that when the heat preservation effect of the panel assembly 100 needs to be improved, the push plate assembly 2 is driven by the driving mechanism 3 to move along the second direction to increase the area of ​​the filling area 111 and reduce the area of ​​the power area 112, so that the area of ​​the compressed heat preservation member filling the filling area 111 increases as the area of ​​the filling area 111 increases, thereby improving the heat preservation area of ​​the panel assembly 100, and further improving the heat preservation effect of the panel assembly 100; when the heat dissipation effect of the panel assembly 100 needs to be improved, the push plate assembly 2 is driven by the driving mechanism 3 to move along the second direction to increase the area of ​​the power area 112 and reduce the area of ​​the filling area 111, so that the area of ​​the compressed heat preservation member filling the filling area 111 decreases as the area of ​​the filling area 111 decreases, thereby reducing the heat preservation area of ​​the panel assembly 100, and further improving the heat dissipation effect of the panel assembly 100. In this way, the heat preservation effect and heat dissipation effect of the panel assembly 100 can be adjusted.

[0033] In some embodiments, when the panel assembly 100 of the present application is applied to a vehicle, the battery pack of the vehicle extends along the second direction, the panel assembly 100 is located below the battery pack and connected to the battery pack, and the lower surface of the battery pack is in contact with the upper surface of the panel body 1.

[0034] When the battery pack needs to be kept warm, for example, when the vehicle is stationary, the BMS (BMS Battery Management System) detects that the external ambient temperature is lower than 25°C; or, when the vehicle is stationary, the BMS detects that the external ambient temperature is lower than 25°C and the BMS determines that the battery pack needs to be kept warm based on the battery temperature, the push plate assembly 2 is driven by the drive mechanism 3 to move in the second direction to increase the area of ​​the filling zone 111 and reduce the area of ​​the power zone 112, so that the area of ​​the compressed insulation filling the filling zone 111 increases as the area of ​​the filling zone 111 increases, thereby increasing the insulation area of ​​the plate assembly 100 for the battery pack, thereby satisfying the insulation effect of the battery pack.

[0035] When the battery pack needs to dissipate heat, for example, when the vehicle is stationary, the BMS detects that the external ambient temperature is lower than 25°C and the BMS determines that the battery pack needs to dissipate heat based on the battery temperature; or when the ambient temperature is higher than 40°C and the vehicle is stationary, running or charging, the push plate assembly 2 is driven by the drive mechanism 3 to move in the second direction to increase the area of ​​the power zone 112 and reduce the area of ​​the filling zone 111, so that the area of ​​the compressed insulation filling the filling zone 111 decreases as the area of ​​the filling zone 111 decreases, thereby reducing the insulation area of ​​the plate assembly 100 for the battery pack and increasing the heat dissipation area of ​​the heat dissipation pack, thereby improving the heat dissipation effect of the battery pack.

[0036] As a result, the thermal insulation performance of the battery pack stored in a low-temperature environment is increased, the low-temperature range and charge and discharge performance of the battery pack are improved, and while the thermal insulation performance of the battery pack is improved, the heat dissipation performance at high temperatures is not affected, thereby improving the reliability of the vehicle.

[0037] Furthermore, the drive mechanism 3 is connected to the BMS for communication. The BMS can comprehensively judge the heat dissipation and heat preservation requirements of the battery pack in real time according to the external environment of the vehicle, the state of the vehicle and the temperature of the battery pack, thereby driving the second push rod to move in the second direction through the drive mechanism 3 in real time to change the areas of the filling area 111 and the power area 112, thereby further solving the problem that the current battery pack cannot have both heat preservation and heat dissipation.

[0038] According to the panel assembly 100 of the embodiment of the utility model, the panel body 1 has a accommodating cavity 11, the push plate assembly 2 is movably arranged in the accommodating cavity 11 and extends along the first direction, the push plate assembly 2 divides the accommodating cavity 11 into a filling area 111 and a power area 112 along the second direction, and is suitable for filling the filling area 111 by compressing the thermal insulation component. The driving mechanism 3 is located in the power area 112 and connected to the panel body 1, and is used to drive the push plate assembly 2 to move along the second direction to change the areas of the filling area 111 and the power area 112, thereby achieving adjustable thermal insulation effect and heat dissipation effect of the panel assembly 100.

[0039] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the push plate assembly 2 includes a first push plate 21 and a second push plate 22 spaced apart along the second direction, the filling area 111 is located between the two push plate assemblies 2, and the power area 112 includes a first area 1121 and a second area 1122. The first area 1121 is located on the side of the first push plate 21 away from the filling area 111, and the second area 1122 is located on the side of the second push plate 22 away from the filling area 111. The driving mechanism 3 in the first area 1121 is used to drive the first push plate 21 to move, and the driving mechanism 3 in the second area 1122 is used to drive the second push plate 22 to move.

[0040] Thus, the accommodating chamber 11 is divided into two first zones 1121 and second zones 1122 constituting a power zone 112 and a filling zone 111 by the first push plate 21 and the second push plate 22. The filling zone 111 is located between the first zone 1121 and the second zone 1122. The driving mechanism 3 in the first zone 1121 is used to drive the first push plate 21 to move, and the driving mechanism 3 in the second zone 1122 is used to drive the second push plate 22 to move, so that the areas of the filling zone 111 for heat preservation and the first zone 1121 and the second zone 1122 for heat dissipation can be adjusted, thereby further meeting the different heat preservation and heat dissipation requirements of the panel assembly 100 and improving the practicality of the panel assembly 100.

[0041] In some embodiments of the present invention, the push plate assembly 2 includes a first push plate 21 and a second push plate 22 spaced apart along a second direction, the power zone 112 is located between the two push plate assemblies 2, there are two filling zones 111, and the two filling zones 111 are respectively located on the sides of the two push plate assemblies 2 facing away from each other, and the driving mechanism 3 is used to drive the first push plate 21 and the second push plate 22 to move toward or away from each other.

[0042] Thus, the accommodating chamber 11 is divided into two filling areas 111 and a power area 112 by the first push plate 21 and the second push plate 22. The power area 112 is located between the two filling areas 111. The first push plate 21 and the second push plate 22 are driven by the driving mechanism 3 to move toward or away from each other, so that the areas of the two filling areas 111 for insulation and the power area 112 for heat dissipation can be adjusted, thereby further meeting the different insulation and heat dissipation requirements of the panel assembly 100 and improving the practicality of the panel assembly 100.

[0043] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the driving mechanism 3 is a hydraulic telescopic rod, which extends along the second direction and is connected to the plate body 1 and the push plate assembly 2 at both ends along the second direction. Therefore, by adjusting the telescopic length of the hydraulic telescopic rod along the second direction, the hydraulic telescopic rod pushes the push plate assembly 2 to move along the second direction, thereby adjusting the areas of the filling area 111 for heat preservation and the power area 112 for heat dissipation to meet the different heat preservation and heat dissipation requirements of the plate assembly 100. At the same time, by accurately controlling the telescopic amount of the hydraulic telescopic rod, the power area 112 and the area of ​​the power area 112 can be accurately adjusted to improve reliability.

[0044] It should be noted that the driving mechanism 3 is not limited to the hydraulic telescopic rod, but can also be implemented by other means such as gears and chains.

[0045] In some embodiments, the push plate assembly 2 includes a first push plate 21 and a second push plate 22 spaced apart along a second direction, the filling area 111 is located between the two push plate assemblies 2, the power area 112 includes a first area 1121 and a second area 1122, the first area 1121 is located on the side of the first push plate 21 away from the filling area 111, and the second area 1122 is located on the side of the second push plate 22 away from the filling area 111, there are two hydraulic telescopic rods, the hydraulic telescopic rod in the first area 1121 is used to drive the first push plate 21 to move, and the hydraulic telescopic rod in the second area 1122 is used to drive the second push plate 22 to move, so that the area of ​​the filling area 111 for insulation and the first area 1121 and the second area 1122 for heat dissipation can be adjusted.

[0046] In some embodiments, the push plate assembly 2 includes a first push plate 21 and a second push plate 22 spaced apart along a second direction, the power zone 112 is located between the two push plate assemblies 2, there are two filling areas 111, and the two filling areas 111 are respectively located on the side of the two push plate assemblies 2 away from each other, there are two hydraulic telescopic rods, and the two hydraulic telescopic rods respectively drive the first push plate 21 and the second push plate 22 to move toward or away from each other, so that the area of ​​the two filling areas 111 for insulation and the power zone 112 for heat dissipation can be adjusted.

[0047] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the push plate assembly 2 has a vent hole 23, and the vent hole 23 is respectively connected to the filling area 111 and the power area 112. Therefore, in the process that the driving mechanism 3 drives the push plate assembly 2 to move along the second direction to change the area of ​​the power area 112 and the filling area 111, the filling area 111 and the power area 112 are connected through the vent hole 23, the air pressure of the filling area 111 and the power area 112 is effectively balanced, and the reliability and safety of the plate assembly 100 are improved.

[0048] Furthermore, the push plate assembly 2 includes a first push plate 21 and a second push plate 22 spaced apart along the second direction. The ventilation holes located on the first push plate 21 and the ventilation holes located on the second push plate 22 are arranged opposite to each other along the second direction to further balance the air pressure in the filling area 111 and the power area 112.

[0049] In some embodiments of the present invention, the air holes 23 are multiple and spaced apart along the first direction. Thus, the air pressure of the filling area 111 and the power area 112 is further ensured by such an arrangement, and the reliability and safety of the panel assembly 100 are improved. It should be noted that the number of the air holes 23 is not limited here, and can be 2, 3 or more.

[0050] In some embodiments of the utility model, the compressed heat-insulating member is a sponge or down. It is understandable that, in the process of the driving mechanism 3 driving the push plate assembly 2 to reduce the area of ​​the filling area 111, the sponge or down filled in the filling area 111 is compressed by the push plate assembly 2, thereby reducing the heat-insulating area of ​​the plate assembly 100, thereby improving the heat dissipation effect of the plate assembly 100; in the process of the driving mechanism 3 driving the push plate assembly 2 to increase the area of ​​the filling area 111, the compressed sponge or down filled in the filling area 111 will be dispersed, thereby increasing the heat-insulating area of ​​the plate assembly 100, thereby improving the heat-insulating effect of the plate assembly 100.

[0051] In some embodiments of the present invention, the push plate assembly 2 includes a body part and a sealing elastic member. The body part is connected to the driving mechanism 3, and the sealing elastic member extends along the circumferential direction of the body part to seal the gap between the body part and the plate body 1. Thus, the gap between the body part and the plate body 1 is effectively sealed by the sealing elastic member, so as to avoid leakage of the compressed heat-insulating member filling the filling area 111 from the filling area 111 to the power area 112, avoid interference with the driving mechanism 3 of the power area 112, and ensure the heat-insulating effect of the plate assembly 100, thereby further improving reliability.

[0052] In some embodiments of the present invention, Figure 1 As shown, the plate body 1 includes an upper shell 12, a lower shell 13 and a frame 14. The lower shell 13 is located below the upper shell 12 and is spaced apart from the upper shell 12. The frame 14 extends along the circumferential direction of the upper shell 12 and is connected to the upper shell 12 at the upper end and to the lower shell 13 at the lower end. The upper shell 12, the lower shell 13 and the frame 14 surround and form a receiving cavity 11. Thus, the upper shell 12, the lower shell 13 and the frame 14 surround and form a sealed receiving cavity 11, thereby protecting the push plate assembly 2, the compression insulation component and the driving mechanism 3 located in the receiving cavity 11, further ensuring that the insulation effect and the heat dissipation effect of the plate assembly 100 are adjustable, and improving reliability.

[0053] Optionally, the upper shell 12 is connected to the upper end surface of the frame 14 by welding or gluing, and the lower shell 13 is connected to the lower end surface of the frame 14 by welding or gluing, thereby forming a sealed accommodating chamber 11.

[0054] The following describes a vehicle according to an embodiment of the present invention.

[0055] According to the vehicle of the embodiment of the utility model, the battery pack and the panel assembly 100 are included. The battery pack extends along the second direction along the up-down direction. The panel assembly 100 is located below the battery pack and connected to the battery pack. The battery pack and the upper end of the panel body 1 are fitted together. The up-down direction, the first direction and the second direction are perpendicular to each other.

[0056] When the battery pack needs to be kept warm, for example, when the vehicle is stationary, the BMS (BMS Battery Management System) detects that the external ambient temperature is lower than 25°C; or, when the vehicle is stationary, the BMS detects that the external ambient temperature is lower than 25°C and the BMS determines that the battery pack needs to be kept warm based on the battery temperature, the push plate assembly 2 is driven by the drive mechanism 3 to move in the second direction to increase the area of ​​the filling zone 111 and reduce the area of ​​the power zone 112, so that the area of ​​the compressed insulation filling the filling zone 111 increases as the area of ​​the filling zone 111 increases, thereby increasing the insulation area of ​​the plate assembly 100 for the battery pack, thereby satisfying the insulation effect of the battery pack.

[0057] When the battery pack needs to dissipate heat, for example, when the vehicle is stationary, the BMS detects that the external ambient temperature is lower than 25°C and the BMS determines that the battery pack needs to dissipate heat based on the battery temperature; or when the ambient temperature is higher than 40°C and the vehicle is stationary, running or charging, the push plate assembly 2 is driven by the drive mechanism 3 to move in the second direction to increase the area of ​​the power zone 112 and reduce the area of ​​the filling zone 111, so that the area of ​​the compressed insulation filling the filling zone 111 decreases as the area of ​​the filling zone 111 decreases, thereby reducing the insulation area of ​​the plate assembly 100 for the battery pack and increasing the heat dissipation area of ​​the heat dissipation pack, thereby improving the heat dissipation effect of the battery pack.

[0058] As a result, the thermal insulation performance of the battery pack when stored in a low-temperature environment is increased, the low-temperature driving range and charge-discharge performance of the battery pack are improved, and the heat dissipation performance at high temperatures is not affected while the thermal insulation performance of the battery pack is improved, thereby improving the reliability of the vehicle. At the same time, by locating the plate assembly 100 below the battery pack, the plate assembly 100 effectively protects the battery pack when the vehicle is driving, reducing the impact of debris on the battery pack, and further improving the reliability and safety of the vehicle.

[0059] Furthermore, the board body 1 includes an upper shell 12, a lower shell 13 and a frame 14. The lower shell 13 is located below and spaced from the upper shell 12, the frame 14 extends along the circumferential direction of the upper shell 12 and is connected to the upper shell 12 at the upper end and to the lower shell 13 at the lower end, the upper shell 12, the lower shell 13 and the frame 14 surround and form the accommodating cavity 11, and the lower surface of the battery pack fits the upper surface of the upper shell 12.

[0060] According to the vehicle of the embodiment of the utility model, a plate assembly 100 is provided, the plate body 1 has a accommodating cavity 11, the battery pack extends along the second direction, the plate assembly 100 is located below the battery pack and connected to the battery pack, the lower surface of the battery pack is in contact with the upper surface of the plate body 1, and the up and down directions, the first direction and the second direction are perpendicular to each other, the push plate assembly 2 is movably arranged in the accommodating cavity 11 and extends along the first direction, the push plate assembly 2 divides the accommodating cavity 11 into a filling area 111 and a power area 112 along the second direction, and is suitable for filling the filling area 111 by compressing the thermal insulation component, the driving mechanism 3 is located in the power area 112 and connected to the plate body 1, and is used to drive the push plate assembly 2 to move along the second direction to change the area of ​​the filling area 111 and the power area 112, thereby increasing the thermal insulation performance of the battery pack when stored in a low temperature environment, improving the low temperature endurance mileage and charging and discharging performance of the battery pack, and while the thermal insulation performance of the battery pack is improved, it will not affect the heat dissipation performance at high temperature, thereby improving the reliability of the vehicle.
