[0002] The power battery pack is the core high-voltage component of new energy vehicles. The battery pack will encounter the impact and extrusion of the front subframe of the vehicle in the frontal collision condition of the whole vehicle. High-voltage problems such as battery pack collision, explosion, fire, smoke, and high-voltage wire harness extrusion often occur. Therefore, if the strength of the battery pack box is simply improved to resist impact, the weight and energy consumption burden of the whole vehicle will increase. Therefore, it is of great significance to balance the weight of the whole vehicle and the protection of the battery pack for reasonable structural design.
[0003] The power cord interface of some battery packs is set at the front or rear end of the battery pack, which makes it very easy for the power cord interface and the power cord plug to cause the battery to be impacted when the entire vehicle is hit. The power cord plug is generally hard in texture and is inserted into the battery. It is very easy to be damaged in a collision and cause serious impact damage to the battery.

[0029] The present invention provides a protective cover. Figures 1 to 4 An embodiment of the protective cover provided by the present invention.
[0030] Please also read Figures 1 to 3The protective cover includes a main body 1, wherein the main body 1 is used to be set at the power interface of the battery 7, the main body 1 has a first side and a second side in a first horizontal direction, the second side is provided with a receiving groove 11, the receiving groove 11 is used to receive the power interface of the battery 7, and the size of the main body 1 in the up and down direction is gradually reduced from the second side to the first side.
[0031] In the present invention, the protective cover includes a main body 1 structure, which is installed at the position of the battery 7 power interface to provide protection for the interface. The main body 1 structure has two opposite sides, which are respectively located on the first side and the second side in the first horizontal direction. On the second side, a receiving groove 11 is opened. The purpose of this receiving groove 11 is to accommodate and cover the battery 7 power interface inside the protective cover body 1. In addition, in order to ensure that the battery 7 power interface is completely covered inside the protective cover body 1, the height dimension of the main body 1 structure in the vertical direction needs to be greater than the height of the battery 7 power interface in the vertical direction. At the same time, in order to prevent the protective cover body from being subjected to excessive impact strength after being hit, the shape of the protective cover body 1 is restricted to a certain extent, specifically, it gradually decreases from the second side to the first side. Such a shape not only ensures that the protective cover can fit tightly to the battery 7 power interface, but also provides a gradual aesthetic feeling in terms of vision and structure.
[0032] In order to further enhance the protective effect of the protective cover, the material selection of the protective cover body 1 should have certain impact resistance and corrosion resistance to adapt to various harsh environments. In addition, the surface treatment of the protective cover should also consider factors such as waterproof and dustproof to ensure reliability in long-term use. The protective cover body 1 can be set to be detachably installed on the battery 7 to facilitate the installation and maintenance of the battery 7 power interface. At the same time, in order to adapt to different models of battery 7 power interfaces, the protective cover can be designed into a variety of specifications to meet the needs of different models.
[0033] Therefore, in the technical solution provided by the present invention, the main body 1 is used to be arranged at the power interface of the battery 7, and the main body 1 has a first side and a second side in the first horizontal direction. The second side is provided with a accommodating groove 11, and the accommodating groove 11 is used to accommodate the power interface of the battery 7. The height of the main body 1 in the up and down direction is gradually reduced from the second side to the first side. By setting the protective cover main body 1, the battery 7 is prevented from being directly hit at the power interface, and the power interface is protected in the protective cover main body 1 to reduce the damage to the power interface during the collision. At the same time, the height of the protective cover in the up and down direction is gradually reduced from the second side to the first side to guide the deviation of the collision direction, so that the impact intensity released by the protective cover main body 1 toward the battery 7 after hitting the protective cover main body 1 is weakened, thereby reducing the damage to the battery 7.
[0034] Furthermore, the main body 1 is provided with an inclined surface, which is inclined from a first side of the upper end surface of the main body 1 toward a second side of the lower end surface of the main body 1 , and the upper end surface of the main body 1 is used for mounting on a vehicle body.
[0035] In this embodiment, the structure of the protective cover body 1 is provided with a slope, which starts from the first side of the upper end face of the protective cover body 1 and extends obliquely along a preset angle toward the second side of the lower end face of the protective cover body 1. This slope can effectively guide objects that hit the protective cover body 1 to move downward along the slope. Through this structure, the impacting object will gradually slow down during the movement, thereby reducing the impact intensity of the impacting object on the impacted protective cover body 1. This structure significantly reduces the damage to the protective cover body 1 and improves the overall performance and service life of the protective cover.
[0036] In order to ensure that the inclined plane can play its due role, the inclination angle of the inclined plane must be strictly limited. If the inclination angle is too large, the impact object may move too fast on the inclined plane, causing the protective cover body 1 to still bear a large impact force. On the contrary, if the inclination angle is too small, the moving distance of the impact object on the inclined plane will become longer, thereby increasing the risk of damage to the protective cover body 1. Therefore, the inclination angle of the inclined plane needs to be accurately calculated and optimized to ensure that it can both guide the impact object to move downward and minimize the damage to the protective cover body 1.
[0037] Furthermore, a through groove 12 is formed on the upper end surface of the main body 1 , and the through groove 12 is communicated with the receiving groove 11 . The through groove 12 is used to receive the power cord 8 plugged into the power interface.
[0038] A notch running through the entire upper end surface is provided on the upper end surface of the main body 1. The through groove 12 is interconnected with the receiving groove 11 inside the main body 1 to form a continuous and seamless passage. The main function and purpose of the through groove 12 is to provide a special space for accommodating and plugging in power cords 8 that need to be connected to the power interface. Through this structure, the power cord 8 can easily pass through the upper end surface of the main body 1 and thus come into contact with the receiving groove. Such a structure not only greatly improves the convenience of plugging in the power cord 8, but also effectively prevents the power cord 8 from being interfered with or accidentally damaged by the outside world during use, thereby ensuring the stable operation of the equipment, and extending the service life of the power cord 8, thereby improving the overall user experience and reliability of the equipment.
[0039] In addition, in order to further optimize the functionality of the protective cover, an elastic snap-on structure can be provided at the opening of the through groove 12, and the elastic snap-on structure can firmly fix the inserted power cord 8 to prevent it from falling off due to vibration during driving. At the same time, the snap-on structure also facilitates the user to quickly and easily remove the power cord 8 when it is not in use, thereby improving the convenience of operation. Furthermore, considering the differences in the layout of the battery 7 power interface of different vehicle models, the shape and size of the protective cover body 1 also need to be adjusted accordingly. Therefore, the protective cover of the present invention can be designed into a modular structure, and users can choose modules of different shapes and sizes to combine according to the actual needs of their own vehicle models to achieve the best adaptation effect. This modular design not only improves the versatility of the protective cover, but also reduces production costs, and brings more choices for users.
[0040] There is still a certain gap at the connection of the protective cover body 1 after installation. After the car wades through water, water may enter the protective cover body 1 through the gap and remain inside it, causing the power cord 8 to be immersed in water and damaged. Therefore, in an embodiment of the present invention, a first sealing gasket 4 is provided on the first side of the main body 1, and the first sealing gasket 4 is provided at the notch of the accommodating groove 11; and or, a second sealing gasket 5 is provided on the upper end face of the main body 1, and the second sealing gasket 5 is provided at the notch of the through groove 12.
[0041] In the embodiment of the present invention, in order to ensure that the protective cover body 1 has better sealing performance after installation, so as to prevent moisture from entering the interior of the protective cover through the gap at the connection during the wading process of the car, causing damage to the internal power line 8, a corresponding sealing measure is specially designed. Specifically, a first sealing gasket 4 is specially arranged on the first side of the protective cover body 1. This first sealing gasket 4 is carefully designed and installed at the notch position of the accommodating groove 11. Its main function is to effectively fill the gap between the protective cover body 1 and related components when the protective cover body 1 is connected, thereby preventing moisture from penetrating into the interior of the protective cover along these gaps. In addition, in order to further enhance the protective effect The present invention also takes into account the upper end surface of the protective cover body 1, on which a second sealing gasket 5 is arranged, and the second sealing gasket 5 is also precisely installed at the notch position of the through groove 12. Through such a design, when the car is wading, even if the water pressure is large, the second sealing gasket 5 can effectively prevent moisture from entering the interior of the protective cover through the notch of the through groove 12, thereby ensuring the safety of the internal power cord 8. In summary, by respectively arranging the first sealing gasket 4 and the second sealing gasket 5 on the first side and the upper end surface of the protective cover body 1, the present invention can significantly improve the sealing performance of the protective cover, effectively prevent moisture from penetrating, and thus protect the internal power cord 8 from damage.
[0042] At the same time, in order to reduce the damage to the power cord 8 inside the protective cover body 1 when it is hit, an auxiliary structure needs to be provided in the protective cover body 1. Specifically, in an embodiment of the present invention, a buffer structure is provided in the through groove, and the buffer structure is used to accommodate the power cord.
[0043] The function of this buffer structure is to absorb and disperse part of the impact force when the protective cover body 1 is hit by external force, thereby reducing the direct impact on the power cord 8 and ensuring the safety of the power cord 8 inside the protective cover. Through this structure, the service life and reliability of the power cord 8 inside the protective cover are significantly improved.
[0044] The buffer structure is usually made of elastic materials, such as rubber or foam plastic, which have good buffering performance and durability. At the same time, the shape and size of the buffer structure are adapted to power cords 8 of different sizes and shapes, ensuring effective protection in various situations. In addition, the installation position of the buffer structure is also optimized so that it can play its role to the maximum extent without affecting other functions of the protective cover, which not only improves the protective ability of the protective cover, but also extends the service life of the power cord 8, providing safer and more reliable protection for the car battery 7 power cord 8 interface.
[0045] Furthermore, the buffer structure includes a buffer block 6 , and a placement groove 61 is formed on the buffer block 6 to accommodate the power line 8 .
[0046] In the present invention, the buffer structure mainly includes a buffer block 6, and the surface of the buffer block 6 is provided with placement grooves 61. The size and shape of these placement grooves 61 can be adapted to the power cord 8. In this way, the power cord 8 can be safely fixed in the placement grooves 61 of the buffer block 6, thereby effectively protecting the power cord 8 from damage caused by external impact and friction. This structure not only improves the service life of the power cord 8, but also ensures the stability and safety of the power cord 8 during use.
[0047] In order to further enhance the protective effect of the buffer block 6, the buffer block 6 in the present invention can also be provided with a plurality of elastic elements, which can fit tightly against the power cord 8 to provide additional buffering and support. The elastic elements are usually made of a material with high elasticity, such as silicone or polyurethane, which can deform when subjected to pressure, thereby absorbing more impact energy. In addition, the interior of the placement groove 61 of the buffer block 6 may also be coated with an anti-slip material to prevent the power cord 8 from being displaced due to vibration during the operation of the vehicle, thereby ensuring that the power cord 8 can be in a suitable protective state.
[0048] Furthermore, the buffer block 6 is detachably disposed in the through slot 12 .
[0049] The buffer block 6 can be designed to be detachable and arranged inside the through groove 12. Specifically, this design enables the buffer block 6 to be easily installed or removed as needed. The through groove 12 provides a specific position where the buffer block 6 can be accurately placed to ensure that its function is fully utilized. The detachable structure is not only convenient for maintenance and replacement, but also allows users to choose different types of buffer blocks 6 according to different application scenarios, thereby improving the flexibility and adaptability of the overall equipment.
[0050] In order to achieve the removability of the buffer block 6, for example, a simple mechanical locking mechanism is designed between the buffer block 6 and the through-slot 12. This mechanism can be a snap-on, threaded or magnetic type to ensure that the buffer block 6 does not accidentally fall off under normal working conditions and can be easily removed manually or with tools when necessary. In addition, the size and shape of the through-slot 12 need to be limited to ensure that the buffer block 6 can fit tightly after installation, thereby avoiding unnecessary vibration or noise during vehicle operation. Through this structure, the buffer block 6 can not only provide effective protection, but also improve the overall user experience and reliability of the equipment.
[0051] In addition, the detachable design of the buffer block 6 also means that when the buffer block 6 is worn or damaged, it can be replaced individually without replacing the entire protective cover, which not only reduces maintenance costs, but also reduces the time consumed by replacing the entire component. The material selection of the buffer block 6 is also very important. It needs to have sufficient elasticity and durability to withstand long-term impact and friction. The buffer block 6 can also be designed to have fire-proof or chemical-resistant properties to adapt to more harsh working environments. Through the optimization of these design details, the overall performance of the protective cover has been significantly improved, providing more comprehensive and effective protection for the power cord 8.
[0052] In order to enhance the impact resistance of the protective cover body 1 , reinforcing ribs 3 are provided on the inclined surface of the body 1 .
[0053] In order to further enhance the anti-impact capability of the protective cover body 1 and ensure that it can better protect the internal power cord 8 when facing external impact, a number of reinforcing ribs 3 are arranged on the inclined surface of the protective cover body 1. The arrangement of these reinforcing ribs 3 not only increases the overall strength of the protective cover, but also effectively disperses the impact force, thereby improving the collision resistance and service life of the protective cover. Through this structural optimization, the protective cover can withstand greater impact force, ensuring that it can still operate stably in various harsh environments, and providing more reliable protection for internal equipment or personnel.
[0054] The reinforcing ribs 3 maximize the structural strength of the protective shield without adding too much weight. In addition, the shape and size of the reinforcing ribs 3 are also optimized to adapt to impact forces in different directions, so as to provide balanced protection at all angles. This design enables the protective shield to maintain its structural integrity when facing impacts from different directions, greatly improving the multi-directional anti-collision performance of the front side of the protective shield body 1.
[0055] The design of the reinforcing rib 3 can be further optimized by dividing it into two independent parts to achieve better functions. Specifically, the reinforcing rib 3 can include two main connecting parts: a first connecting part and a second connecting part. The first connecting part is responsible for connecting with the main body 1 structure, and the second connecting part is arranged at a corresponding position of the main body 1 structure. In order to ensure the stability and durability of the overall structure, the first connecting part adopts a material with buffering properties. This material can effectively absorb and disperse the impact force from the outside, thereby reducing the impact strength borne by the second connecting part, so that the first connecting part plays a protective role to a certain extent, ensuring that the second connecting part will not be damaged due to direct excessive impact. At the same time, the second connecting part adopts a harder material. The selection of this material is to improve the overall impact resistance of the reinforcing rib 3. The harder material can better resist external impact and pressure, thereby ensuring that the reinforcing rib 3 can still maintain its structural integrity and functionality when subjected to a strong impact, so that the second connecting part can provide stronger support and protection when subjected to impact, further enhancing the stability and safety of the overall structure.
[0056] In order to facilitate maintenance of the battery 7 power line 8 interface, a clamping structure 2 is provided on the second side of the main body 1 , and the clamping structure 2 is used to clamp in the clamping slot on the battery 7 .
[0057] In order to facilitate the maintenance and management of the battery 7 power line 8 interface, a card connection structure 2 is provided on the second side of the main body 1 structure of the present invention. The main function of the card connection structure 2 is to hold and fix the corresponding card slot on the battery 7. Through this structure, it can be ensured that the battery 7 power line 8 interface remains stable during use, and it is also convenient for rapid disassembly and replacement of the battery 7 when necessary. The provision of the card connection structure 2 not only improves the reliability of the battery 7 power line 8 interface, but also greatly simplifies the complexity of maintenance operations, making the maintenance of the entire system more convenient and efficient.
[0058] In addition, the design of the snap-in structure 2 also takes into account the convenience of operation. It has a simple structure and is easy for users to operate, reducing possible errors during maintenance. In terms of design, the snap-in structure 2 uses durable materials to ensure that its performance will not be affected by wear during long-term use. At the same time, in order to adapt to batteries 7 of different sizes, the snap-in structure 2 also has a certain adjustment range to ensure wide applicability. Through these design details, the present invention significantly improves the maintenance efficiency of the battery 7 power cord 8 interface and the stability of the overall system.
