[0037] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in various different forms, and should not be construed as being limited to only the embodiments set forth herein. It is understood that the embodiments are provided so as to make the present application thoroughly and completely, and to fully convey the concept of the exemplary embodiments to those having ordinary knowledge in the art, and in the drawings, the thicknesses of layers and regions can be exaggerated for clarity, and the same reference numerals are used throughout the drawings and thus repeated descriptions are omitted.

[0038] In conjunction with Figures 1 to 3 As shown, according to specific embodiments of the present application, a battery cover device and a vehicle with the same are provided.

[0039] Specifically, as Figure 1 shown, the battery cover device comprises a battery cover 10, the battery cover 10 is provided with a containing cavity 11 with one side opening, a plurality of mounting positions 12 are circumferentially arranged on the battery cover 10, the plurality of mounting positions 12 are arranged close to the opening side of the containing cavity 11, the battery cover 10 has an assembly position when assembled with the vehicle, when the battery cover 10 is located at the assembly position, the opening of the containing cavity 11 is arranged to face the top side of the vehicle, and the battery of the vehicle is located in the containing cavity 11.

[0040] The technical scheme of the present application is applied, by designing the battery cover 10 as a containing cavity 11 with one side opening, and circumferentially arranging a plurality of mounting positions 12 close to the opening, to ensure that the opening direction of the battery cover 10 is downward when assembled to the top of the vehicle, effectively wrapping the battery of the vehicle. This inverted design significantly improves the waterproof performance, completely avoids direct contact of rainwater with the battery, optimizes the battery installation and maintenance process, improves the space utilization rate and maintenance convenience, and solves the problems of poor waterproof performance and large space occupation in the prior art.

[0041] Further, the battery cover 10 comprises a cabin skeleton 101 and a cabin skin 102. The cabin skin 102 is arranged on the outside of the cabin skeleton 101, and the cabin skin 102 and the cabin skeleton 101 together form a containing cavity 11 with one side opening.

[0042] The cabin skeleton 101 serves as the "skeleton" of the battery cover 10, providing the necessary structural strength to withstand external impacts and various stresses, while supporting the cabin skin 102 to ensure the shape and size accuracy of the entire battery cover 10, and providing a safe installation environment for the internal battery components.

[0043] The cabin skin 102 is made of glass steel material, which has good waterproof performance and weather resistance. It covers the outside of the cabin skeleton 101 and closely adheres to the cabin skeleton 101, and is firmly combined together through glass fiber bonding technology to form the external protective layer of the battery cover 10. The cabin skin 102 not only has an attractive appearance, but more importantly, it provides a waterproof barrier for the battery components, preventing direct contact of rainwater with the battery and avoiding water damage and potential electrical short circuit risks. At the same time, the selection of glass steel material makes the cabin skin 102 have the characteristics of lightweight and high strength, which reduces the weight of the battery cover 10 and improves the load-bearing capacity of the structure.

[0044] The containing cavity 11 formed by the cabin skeleton 101 and the cabin skin 102 has one side opening, which is designed for the installation and maintenance of the battery components. During installation, the battery can be placed into the containing cavity 11 through the opening, and when maintenance or repair is needed, the battery components can be easily accessed through the opening.

[0045] The design of the containing cavity 11 ensures the protection of the battery components and maximizes the installation space, while also considering the convenience of maintenance, reducing maintenance time and improving production efficiency. The optimized use of the internal space helps to improve the flexibility of the battery pack arrangement, which may improve the vehicle's endurance and power performance.

[0046] Specifically, the cabin skeleton 101 is made of square steel. The cabin skeleton 101 selects square steel as the main material, which has good mechanical strength and rigidity and can provide stable support for the battery cover to resist external impact and load. The quadrilateral cross-section of the square steel makes it have high bending resistance in different directions, which is suitable for constructing a frame.

[0047] In a specific embodiment, the cabin skeleton 101 is welded by CO2 gas shielded welding from KQF20101.5 / Q355C square steel, forming a stable and sufficient strength support structure. The welding process ensures the strength and sealing of the connection of the cabin skeleton 101, and the specification and material selection of the square steel meet the requirements of support capacity and durability. The top, side and bottom of the skeleton are respectively reserved for mounting and connecting points for bonding with the cabin skin 102 and fixing with the top of the vehicle. This design not only provides physical protection for the battery assembly, but also ensures the reliability and durability of the battery cover 10 under various environmental conditions.

[0048] Specifically, the cabin skeleton 101 includes a first skeleton 1011 and a second skeleton 1012, the first skeleton 1011 is arranged along the length direction of the battery cover 10, and the second skeleton 1012 is arranged along the width direction of the battery cover 10, and the first skeleton 1011 is connected with the second skeleton 1012.

[0049] As shown in Figure 2 The first skeleton 1011 is arranged along the length direction of the battery cover 10 and is composed of square steel material, providing rigid support for the battery cover 10 in the length direction, ensuring that the battery cover 10 can withstand longitudinal loads, and it also serves as a fixing point for the cabin skin 102, forming a close combination with the cabin skin 102 and enhancing the waterproof performance and overall strength of the battery cover 10.

[0050] The second skeleton 1012 is arranged along the width direction of the battery cover 10 and is also composed of square steel material, which is connected perpendicularly with the first skeleton 1011 to form a grid or frame structure. The second skeleton 1012 can strengthen the support of the battery cover in the width direction, together with the first skeleton 1011 to form a stable three-dimensional frame, improving the compression resistance and torsion resistance of the entire battery cover 10, ensuring that the battery cover 10 can protect the internal battery from damage under various environmental conditions. In addition, this grid-like design also helps to evenly support the cabin skin 102, preventing deformation caused by uneven local stress.

[0051] The first skeleton 1011 and the second skeleton 1012 are firmly combined at the intersection points by welding or bolt connection, etc., forming a three-dimensional skeleton structure of the battery cover 10. This connection method ensures the integrity and rigidity of the skeleton structure, which can maintain the stability of the frame even under extreme conditions, providing reliable protection for the internal battery. At the same time, the firm connection points also improve the durability and life of the battery cover 10, reducing maintenance costs.

[0052] In a specific embodiment, the first framework 1011 and the second framework 1012 of the cabin framework 101 are both made of square steel material of KQF20*10*1.5 / Q355C. The first framework 1011 extends along the length direction of the battery cover 10 (i.e. the driving direction of the vehicle), while the second framework 1012 extends along the width direction of the battery cover 10 (i.e. the lateral direction of the vehicle), and the two are firmly combined at the intersection point by CO2 gas shielded welding to form a grid-shaped frame. This framework structure not only provides physical support for the battery cover 10, but also enhances the waterproof performance of the battery cover 10 through close adhesion with the cabin skin 102. In actual application, the combination of the first framework 1011 and the second framework 1012 can ensure that the battery cover 10 remains structurally stable when subjected to wind pressure and rain impact on the roof, providing comprehensive protection for the internal battery components. At the same time, the design and material selection of the framework also consider the balance between light weight and strength, so that the entire battery cover 10 is both stable and does not excessively increase the weight burden of the vehicle.

[0053] Specifically, the first framework 1011 is a plurality of first frameworks 1011 arranged at intervals along the width direction of the battery cover 10, and the plurality of first frameworks 1011 are connected with the second framework 1012.

[0054] As shown in Figure 2 In this embodiment, three first frameworks 1011 are provided, each extending along the length direction, and each first framework 1011 serves as an independent support to share the longitudinal load of the entire battery cover. However, the three first frameworks 1011 are uniformly and evenly distributed along the width direction, which not only ensures the structural strength of the battery cover 10 in the length direction, but also provides multiple independent areas for the installation and layout of the battery components, optimizing the utilization efficiency of the internal space of the battery cover. The cross connection of the plurality of first frameworks 1011 and the plurality of second frameworks 1012 provides omnidirectional support for the battery cover 10 in the length and width directions.

[0055] Specifically, the second framework 1012 is a plurality of second frameworks 1012 arranged at intervals along the length direction of the battery cover 10, and the plurality of second frameworks 1012 are connected with the plurality of first frameworks 1011.

[0056] As shown in Figure 2As shown, three second skeletons 1012 are arranged in the embodiment, each extending along the width direction, but the three second skeletons 1012 are uniformly spaced along the length direction. This layout not only ensures the structural strength of the battery cover 10 in the width direction, but also provides multiple independent areas for the installation and layout of the battery assembly. The cross connection of the multiple first skeletons 1011 and the multiple second skeletons 1012 provides omnidirectional support of the battery cover 10 in the length and width directions. The cross connection of the multiple first skeletons 1011 and the multiple second skeletons 1012 not only improves the overall rigidity of the battery cover, but also enhances its vibration absorption capacity under complex road conditions, reduces the direct impact on the battery, and prolongs the service life of the battery.

[0057] Specifically, a plurality of mounting positions 12 are formed on the cabin skin 102, and the mounting position 12 is a recessed mounting groove provided on the cabin skin 102. The design of the mounting groove can realize the rapid and accurate installation of the battery cover 10, reduce the error of manual operation, and improve the efficiency.

[0058] The mounting position 12 refers to a recessed area provided on the cabin skin 102, which is specifically a mounting groove. These mounting grooves are spaced along the surface of the cabin skin 102 according to the layout of the cabin skeleton 101 and the size of the battery assembly, and are usually perpendicular to the direction of the second skeleton 1012. As shown, Figure 2 As shown, there are specifically six mounting positions 12 in the embodiment. By arranging the mounting positions 12 along the surface of the cabin skin 102, the internal space of the battery cover can be better planned and utilized, and the efficient layout of the battery assembly can be realized.

[0059] Specifically, the long side direction of the mounting groove extends along the height direction of the cabin skin 102, and a connecting hole 121 is arranged on the side wall of the mounting groove close to the opening side of the accommodating cavity 11. The arrangement of the connecting hole 121 makes the installation of the battery cover 10 more convenient, and also facilitates the later maintenance and upgrading.

[0060] The mounting groove is designed to extend along the height direction of the cabin skin 102, that is, perpendicular to the driving direction and the width direction of the vehicle, and is usually arranged at the top or side of the battery cover 10. This design makes the long side of the mounting groove consistent with the vertical height of the vehicle, facilitating the vertical positioning and fixing of the battery assembly, while reducing the additional pressure on the structure of the cabin skin 102 and the cabin skeleton 101 in the horizontal direction.

[0061] According to another aspect of the utility model, provide a kind of vehicle, including battery cover device, battery cover device is the battery cover in above-mentioned embodiment, wherein, vehicle includes vehicle body 20 and battery bracket 30, battery bracket 30 is set to the top of vehicle body 20, battery cover is set to the top of vehicle body 20, and battery cover is connected with at least one of vehicle body 20 and battery bracket 30 by mounting site 12.By at least one of battery cover 10 with vehicle body 20 and battery bracket 30 connection, electric taxi and electric logistics vehicle and other vehicles can be completed in short time battery replacement, without long time waiting for charging, significantly improve the operational efficiency of vehicle, reduce operating cost.

[0062] Vehicle body 20 is the main structure of vehicle, including car body, roof, support frame and other parts.The structure of roof needs to be matched with the design of battery bracket 30 and battery cover 10, to ensure the stable installation of battery system.Vehicle body 20 provides the basic platform for battery cover device installation.

[0063] As shown in Figure 3 Battery bracket 30 is a support structure installed on the top of vehicle body 20, used for carrying and fixing power battery.Battery bracket 30 is usually made of high-strength material, with good load-bearing capacity.The lower part of battery bracket 30 has preset mounting hole, used for bolt connection with fixed point on roof.Battery bracket 30 provides direct support and positioning for battery assembly, ensuring the stability and safety of battery during vehicle operation.

[0064] The upper part of battery bracket 30 is provided with mounting bracket, which provides direct mounting support point for battery cover device.These mounting brackets are usually provided with preset bolts, and the length and diameter of the bolts need to be matched with the mounting hole 121 of battery cover 10.During installation, the fixing part on battery bracket 30 is aligned with the connecting hole 121 in mounting slot, and the battery cover 10 and battery bracket 30 are tightly connected through bolts and nuts or other fasteners.

[0065] Through the above design, battery cover 10 and vehicle body 20 and battery bracket 30 form an integral whole, ensuring the safety and stability of power battery in roof position.At the same time, the quick installation and disassembly function of battery cover 10 improves the maintenance efficiency of battery system, reduces the time cost of repairing and replacing battery assembly.

[0066] Specifically, battery cover 10 is detachably connected with battery bracket 30 through mounting site 12.The detachable connection design enables battery cover 10 to be quickly replaced when damaged, without the need to replace vehicle body 20 or battery bracket 30 as a whole, reducing maintenance cost.

[0067] The mounting position 12 is a groove designed on the cabin skin 102, and the long edge direction extends along the height direction of the cabin skin 102, which is used to be connected with the mounting bracket on the battery bracket 30. These mounting brackets are usually provided with preset bolts, which are convenient for quick docking with the connecting hole 121 of the battery cover. The waterproof gasket or sealant is used between the connecting hole 121 and the bolt connection, which ensures the waterproof sealing of the connection between the battery cover 10 and the battery bracket 30, prevents rainwater from entering the inside of the battery cover 10, and protects the battery assembly from being damaged.

[0068] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0069] 1. By designing the battery cover as an open cavity structure on one side, and circumferentially arranging a plurality of mounting positions close to the opening, it is ensured that the opening direction of the battery cover is downward when it is assembled to the top of the vehicle, and the vehicle battery is effectively wrapped. This "inverted buckle" design significantly improves the waterproof performance, completely avoids direct contact of rainwater with the battery, and also provides sufficient installation space to allow flexible layout of the battery assembly, thereby optimizing the arrangement of the power battery on the roof of the vehicle, increasing the utilization rate of the internal space, and improving the energy efficiency and driving performance of the vehicle.

[0070] 2.
