Description

Technical Field

[0001] This utility model relates to the field of battery equipment technology, and more specifically, to a sunshade and a battery device. Background Technology

[0002] In existing technologies, battery pack installations generally lack effective sunshading and protection measures. Battery packs are typically directly exposed to the environment, especially direct sunlight, causing the internal temperature of the battery to rise significantly with increasing sunlight exposure. Prolonged exposure to high temperatures gradually degrades battery performance and increases the risk of thermal runaway, posing a threat to battery safety and lifespan.

[0003] In other words, existing battery devices have a high risk of thermal runaway. Utility Model Content

[0004] The main objective of this invention is to provide a sunshade and a battery device to address the high risk of thermal runaway in battery devices in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a sunshade is provided for shading a battery pack from the sun. The sunshade includes at least one sunshade panel, which includes a panel body having at least one ventilation hole.

[0006] Furthermore, the plate has a central area and mounting areas located on both sides of the central area, and each mounting area has multiple mounting holes.

[0007] Furthermore, multiple mounting holes are spaced apart along a first direction, which is perpendicular to the arrangement direction of the central area and the mounting area.

[0008] Furthermore, the central area has at least one ventilated sub-region, and the ventilated sub-region has multiple ventilated holes.

[0009] Furthermore, when there are multiple breathable sub-regions, the multiple breathable sub-regions are spaced apart along the first direction.

[0010] Furthermore, the central area also has at least one shielding sub-area, which has multiple blind holes located on the side surface of the plate opposite to the battery pack.

[0011] Furthermore, when there are multiple ventilated sub-regions, the shading sub-region is located between two adjacent ventilated sub-regions; the multiple ventilated through holes and multiple blind holes are arranged in a matrix.

[0012] Furthermore, the plate has at least one reinforcing rib, which is disposed on one side of the plate in the thickness direction.

[0013] Furthermore, the reinforcing ribs include a plurality of first reinforcing ribs arranged along a first direction and a plurality of second reinforcing ribs arranged along a second direction, wherein the first direction and the second direction intersect.

[0014] According to another aspect of the present invention, a battery device is provided, including a battery pack and the aforementioned sunshade, wherein the sunshade's sun visor is disposed on one side of the battery pack.

[0015] Using the technical solution of this utility model, a sunshade is used to shade a battery pack. The sunshade includes at least one sunshade plate, which includes a plate body and has at least one ventilation hole.

[0016] The sun visor effectively blocks direct sunlight, reducing the impact of solar heat radiation on the battery pack. The vented design allows airflow, helping the battery pack dissipate heat generated by internal chemical reactions, maintaining it within a suitable operating temperature range and preventing performance degradation and thermal runaway risks caused by high temperatures.

[0022] To address the high risk of thermal runaway in battery devices in related technologies, this invention provides a sunshade and a battery device.

[0023] like Figure 1 As shown, the battery device includes a battery pack 80 and a sunshade as described below. The sunshade includes at least one sun shade plate, which is connected to the battery pack 80 by a fastener 90, so that the sun shade plate can shade the battery pack 80, reduce direct sunlight on the battery pack 80, reduce the heat at the battery pack 80, and thus reduce the risk of thermal runaway of the battery pack 80.

[0024] In addition, the sunshade's waterproof and dustproof properties protect the battery pack 80 from external environmental influences, reducing the risk of corrosion and electrical short circuits, and improving the reliability of the battery system.

[0025] In some alternative embodiments, the sunshade has two sun visors, which are respectively disposed on opposite sides of the battery pack 80 in the vertical direction.

[0026] like Figures 1 to 5 As shown, the sunshade is used to shade the battery pack 80. The sunshade includes at least one sunshade panel, which includes a panel body 10 and has at least one ventilation hole 20.

[0027] The sun visor effectively blocks direct sunlight, thus reducing the impact of solar heat radiation on the battery pack. The ventilation holes 20 allow airflow, helping the battery pack 80 dissipate heat generated by internal chemical reactions, maintaining the battery pack within a suitable operating temperature range, and preventing battery performance degradation and thermal runaway risks caused by high temperatures. The sun visor utilizes the ventilation holes 20 to promote airflow, achieving heat dissipation and cooling, reducing heat accumulation in the battery pack 80, and effectively controlling the battery pack's operating temperature.

[0028] In addition to blocking sunlight, the sunshade not only reduces direct contact between rainwater and the battery pack, preventing short circuits or corrosion caused by rainwater. Simultaneously, the sunshade also prevents dust and foreign objects from entering, keeping the battery pack surface clean and reducing heat dissipation problems and electrical contact issues caused by dust.

[0029] like Figure 2 and Figure 4 As shown, the panel 10 has a central area 40 and mounting areas 50 located on both sides of the central area 40, each mounting area 50 having multiple mounting holes 60. Fasteners 90 pass through the mounting holes 60 in the mounting areas 50 to achieve a reliable connection between the sunshade and the battery pack 80. This design ensures that the sunshade will not loosen or fall off due to external environmental factors such as wind or vibration, ensuring safety and stability during long-term use.

[0030] The panel 10 is divided into two parts: a central area 40 and a mounting area 50. The mounting area 50 is mainly used for fixing, while the central area 40 serves as the main area for sun shading and ventilation. Placing the mounting areas 50 on both sides of the central area 40 can reduce the risk of the sunshade squeezing or colliding with the middle of the battery pack 80.

[0031] Alternatively, fastener 90 can be a screw.

[0032] like Figure 2 and Figure 4 As shown, multiple mounting holes 60 are spaced apart along a first direction, which is perpendicular to the arrangement direction of the central area 40 and the mounting area 50. The spaced mounting holes 60 along the first direction ensure that the sunshade is evenly stressed during installation, avoiding installation instability problems such as tilting, sliding, or loosening caused by excessive stress at a certain point.

[0033] Under wind conditions, the sunshade may be subjected to significant lateral forces. By providing and securing it with vertical mounting holes 60, the sunshade's wind resistance can be significantly improved, preventing displacement or damage in strong winds and thus protecting the battery pack 80 from environmental factors.

[0034] like Figure 4 As shown, the central region 40 has at least one ventilated sub-region 41, which has multiple vent holes 20. The vent holes 20 allow air to circulate freely around the battery pack 80, helping to regulate the temperature at the battery pack 80. In high-temperature environments, these vent holes 20 can promote the exhaust of hot air and introduce cool air, thereby reducing the surface and internal temperature of the battery pack 80 and preventing battery performance degradation and safety risks due to overheating. During battery operation, chemical reactions generate heat. Without good ventilation, the heat inside the battery pack 80 will be difficult to dissipate effectively, potentially leading to heat accumulation. The presence of the ventilated sub-region 41 can accelerate air circulation, prevent heat accumulation around the battery pack 80, and help maintain the battery's thermal stability and extend its lifespan.

[0035] In addition, the central area 40 of the sunshade includes a ventilated sub-area 41, which helps reduce wind pressure differences caused by strong winds and prevents deformation or damage to the sunshade due to wind pressure differences. The vents 20 help balance the internal and external air pressure, improving the stability of the sunshade under adverse weather conditions.

[0036] like Figure 4 As shown, when there are multiple ventilated sub-regions 41, these sub-regions 41 are spaced apart along a first direction. Spacing the ventilated sub-regions 41 along the first direction (the length direction of the sunshade) ensures uniform airflow throughout the entire length of the sunshade. This design avoids the "blocking" effect of airflow, allowing for more thorough air exchange between the inside and outside of the sunshade, which helps to evenly dissipate heat from the battery pack 80 and prevents localized overheating. The arrangement of multiple ventilated sub-regions 41 increases the ventilated area of ​​the sunshade, thereby improving airflow speed and heat dissipation efficiency. In high-temperature environments, the heat generated by the battery pack 80 can be dissipated more quickly through these vents 20, reducing the internal temperature of the battery, extending the service life of the battery pack 80, and maintaining its stable performance.

[0037] Furthermore, the spaced arrangement of the ventilated sub-regions 41 reduces wind resistance, prevents strong winds from forming eddies within the sunshade, and lowers wind-induced noise. Simultaneously, this design also contributes to the stability of the sunshade under wind conditions, reducing the physical impact of wind on the sunshade and battery pack.

[0038] Preferably, there are two ventilated sub-regions 41, which are located at opposite ends of the central region 40 in the first direction to reduce wind resistance.

[0039] like Figure 4 As shown, the central area 40 also has at least one shading sub-area 42, which has multiple blind holes 70 located on the side surface of the plate 10 facing away from the battery pack 80. The shading sub-area 42 can not only block sunlight and reduce the direct heat radiation of sunlight to the battery pack 80, but also block rainwater and reduce the erosion of the battery pack 80 by rainwater.

[0040] Furthermore, the blind holes 70 do not penetrate the entire panel 10, thus not affecting the sunshade's shading effect. The design of the blind holes 70 takes into account structural mechanics principles. By setting blind holes in specific areas of the panel 10, localized lightweighting of the sunshade can be achieved without significantly reducing the overall material strength. This localized lightweighting design improves the overall structural strength and rigidity of the sunshade, especially on the side facing away from the battery pack 80. The layout of the blind holes 70 more effectively resists external forces such as wind pressure and vibration, reducing deformation and damage. The specific layout and shape of the blind holes 70 enhance the product's recognizability and aesthetics.

[0041] like Figure 4 As shown, when there are multiple ventilated sub-regions 41, the shading sub-region 42 is located between two adjacent ventilated sub-regions 41. The alternating arrangement of the shading sub-regions 42 and ventilated sub-regions 41 ensures a more uniform heat distribution around the battery pack. The shading sub-region 42 effectively blocks direct sunlight, reducing heat concentration, while the ventilated sub-regions 41 promote airflow through multiple ventilation holes 20, facilitating heat dissipation. This design prevents localized overheating and helps maintain the overall temperature stability of the battery pack. The shading sub-region 42 plays a primary role in sun shading, while the ventilated sub-region 41 focuses on heat dissipation. Alternating between them allows the sun shading and heat dissipation functions to complement each other, creating a synergistic effect. The shading sub-region 42 reduces the heat entering the battery pack 80, while the ventilated sub-region 41 accelerates the dissipation of heat from the battery pack outwards; together, the temperature control of the battery pack is improved.

[0042] Furthermore, the shielding sub-regions 42 are generally solid or semi-solid designs, possessing high structural strength. Located between the ventilated sub-regions 41, they increase the overall rigidity of the sunshade, preventing the presence of vents from weakening the load-bearing capacity of the panel 10. Additionally, under wind conditions, the shielding sub-regions 42 provide extra protection, reducing the impact of wind on the sunshade and improving its wind resistance.

[0043] like Figure 4As shown, multiple vent holes 20 and multiple blind holes 70 are arranged in a matrix. On the one hand, the matrix arrangement of the vent holes 20 ensures a uniform distribution of airflow areas on the sunshade surface, thus avoiding excessive concentration of local airflow and preventing localized overcooling or overheating of the battery pack. Uniform airflow helps to balance the overall temperature of the battery pack and improve thermal management efficiency. On the other hand, the matrix layout of the blind holes 70, without penetrating the plate 10, forms microstructures through localized material removal. These microstructures increase the overall rigidity and stability of the plate to a certain extent. The matrix layout of the blind holes can be seen as tiny negative space supports, which help to disperse external forces and reduce deformation caused by wind, heavy object impacts, etc.

[0044] In addition, the ventilation holes 20 and blind holes 70 are arranged in a matrix, which can improve the aesthetics of the sunshade.

[0045] like Figure 3 As shown, the panel 10 has at least one reinforcing rib 30, which is disposed on one side of the panel 10 in the thickness direction. The placement of the reinforcing rib 30 on one side of the panel 10 increases the mechanical strength of the sunshade, enabling it to maintain structural stability and integrity when facing wind, flying stones, or rain impacts, extending the service life of the sunshade, and also protecting the battery pack from physical damage.

[0046] The sun visor utilizes ventilation holes 20 to promote air circulation, achieving heat dissipation and cooling, reducing heat accumulation at the battery pack 80, and effectively controlling the battery pack's operating temperature. The reinforcing ribs 30 increase the overall structural strength of the sun visor, preventing deformation or damage caused by wind, external impacts, etc., thus ensuring the stability of the sun visor's operation.

[0047] like Figure 3 As shown, the reinforcing rib 30 includes multiple first reinforcing ribs 31 arranged along a first direction and multiple second reinforcing ribs 32 arranged along a second direction, with the first and second directions intersecting. The intersecting arrangement of the first reinforcing ribs 31 and the second reinforcing ribs 32 forms a mesh structure, which can greatly improve the overall structural strength and rigidity of the sunshade. This enhanced structural stability makes the sunshade more resistant to external physical impacts, such as strong winds, hail, and flying stones, protecting the battery pack from damage.

[0048] By setting the first reinforcing rib 31 and the second reinforcing rib 32 to be intersected in different directions, the force acting on the plate 10 can be effectively distributed, preventing twisting or deformation caused by unidirectional force, so that the sunshade can maintain a good shape and ensure the sunshade effect.

[0049] Preferably, the first direction is perpendicular to the second direction.

[0050] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: 1. Ventilation and heat dissipation: The presence of vents 20 allows for smooth airflow, effectively reducing the temperature of the battery pack 80, avoiding safety issues caused by overheating, and extending battery life.

[0051] 2. Structural stability: The staggered arrangement of the reinforcing ribs 30 significantly enhances the strength and stability of the plate 10. Even under severe conditions such as strong winds, the sunshade can still maintain its original shape and will not deform.

[0052] 3. Rain and dust protection: The shielded sub-area 42 provides comprehensive rain and dust protection, reducing battery pack maintenance costs and failure rates, and enhancing system reliability.

[0053] 4. Easy installation: The 60mm mounting hole design simplifies the installation process of the sunshade, not only shortening the installation time but also ensuring precise alignment between the sunshade and the battery pack, thus enhancing user-friendliness.

[0054] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0055] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0056] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
