Description

TECHNICAL FIELD

[0001] The present application relates to the field of new energy vehicles, in particular to a battery box locking device for vehicles with sealing and waterproof functions. BACKGROUND

[0002] With the rapid development of new energy vehicles, the battery box, as one of the core components, plays a crucial role in ensuring safety and performance. Especially under the current background of increasing requirements for new energy vehicles, the sealing and waterproof performance of the battery box has become a key design requirement. The battery box usually includes an openable inspection position and an inspection opening, which are connected and locked by a locking device to ensure the sealing of the battery box. However, the existing locking device design often has some shortcomings, especially in terms of waterproof performance, which cannot effectively cope with high-intensity water environments.

[0003] Traditional locking devices focus more on physical connection and locking effect, while ignoring the waterproof needs of the battery box in complex environments. These locking devices usually lack effective sealing structures, which can allow water to enter the battery box through the locking device in water-related situations. The entry of water not only affects the normal operation of the battery, but also can cause serious damage to the electronic components inside the battery box. Therefore, the existing locking device cannot fully meet the strict requirements of high-end new energy vehicles for the sealing of the battery box, especially in high-intensity water-related scenarios, and cannot effectively prevent water from entering, affecting the safety of the battery box and the service life of the battery.

[0004] In addition, the existing locking device also has another significant defect, which is the lack of water-related display function. The current locking device cannot monitor and display the severity of water-related situations in real time, making it difficult for vehicle owners and maintenance personnel to understand whether the battery box has been invaded by water or the extent of the water invasion. Especially when driving in deep water environments, the battery box may be damaged due to rising water levels, but due to the lack of real-time water level monitoring or warning functions, the vehicle owner cannot take immediate action to prevent further damage to the battery. The root cause of this problem is that the existing locking device design does not fully consider the need for intelligent monitoring and is not closely integrated with intelligent sensing technology.

[0005] Therefore, it is particularly important to develop a battery box locking device for vehicles that not only has sealing and waterproof functions, but also can display the severity of water-related situations in real time. CONTENT OF THE INVENTION

[0006] The purpose of this application is to overcome at least one deficiency of the existing technology and provide a vehicle battery box locking device with a sealing and waterproof function. This new locking device can effectively prevent water from entering the battery box, meeting the stringent sealing requirements of high-end new energy vehicles. Simultaneously, by incorporating a wading indicator, it facilitates quick assessment of the battery box's water immersion status during vehicle maintenance, providing timely warnings to vehicle owners and preventing battery damage or safety accidents caused by water intrusion.

[0007] To achieve the above objectives, this application discloses a vehicle battery box locking device with a sealing and waterproof function. The battery box locking device includes a T-shaped body and a wading sensor block installed within the T-shaped body. The T-shaped body includes a head with a bolt groove recessed on its outer end face and a threaded rod portion coaxially connected and integrally fixed to the inner end face of the head. The bottom of the bolt groove in the head of the T-shaped body has a recessed mounting groove for the wading sensor block. The inner end face of the head has a multi-layer sealing structure, consisting of an outer annular protrusion from the outside in, a... A rubber ring is fixed to the head body; a water-retaining cap extends radially from the outer side of the head; the wading sensing block is a rubber block that is interference-fitted with the mounting groove, so that the wading sensing block is fixed in the mounting groove and is spaced apart from the bottom of the mounting groove to form a sensing cavity; a water inlet hole is provided in the center of the wading sensing block and is coaxially connected to the T-shaped body, so that the sensing cavity is connected to the external environment through the water inlet hole; a water-sensitive color-changing sticker is installed on the surface of the wading sensing block opposite to the bottom of the mounting groove, and the water-sensitive color-changing sticker is located inside the sensing cavity.

[0008] In some embodiments, the rubber ring protrudes above the outer annular protrusion.

[0009] In some embodiments, a drying block is installed inside the sensing cavity.

[0010] Compared with the prior art, this application has at least one beneficial effect:

[0011] 1. Improved sealing and waterproof performance: By designing a multi-layer sealing structure at the head of the fastener, including the combination of an outer ring protrusion and a rubber ring, the sealing performance of the battery box fastener is ensured in high-intensity water immersion environments. This significantly improves the waterproof capability of the battery box, effectively preventing moisture from entering the battery box through the fastener, ensuring the normal operation of the battery and electronic components, and extending the battery's lifespan.

[0012] 2. Water Immersion Monitoring and Indication Function: This new type of locking device incorporates a water immersion sensor and a water-sensitive color-changing sticker, which can monitor and display in real time whether the battery box has been submerged in water. The water-sensitive color-changing sticker indicates the degree of water intrusion through color changes, allowing vehicle owners and maintenance personnel to quickly determine the water immersion status of the battery box, providing a basis for taking timely protective measures and reducing potential damage caused by water intrusion.

[0013] 3. Simplify the maintenance inspection process: By setting the structure of the induction cavity and the water inlet hole, combined with the design of the dry block, the humid environment in the induction cavity is effectively avoided, ensuring the accuracy and long-term stability of the induction block. In addition, the application of water-sensitive color-changing stickers allows car owners and maintenance personnel to determine whether there is water intrusion without disassembling the battery box, significantly simplifying the maintenance inspection process and improving maintenance efficiency.

Embodiments

[0023] Referring to the drawings Figs. 1-3 The present embodiment provides a battery box locking device with sealing and waterproof function for vehicles, aiming to solve the sealing and waterproof problem of new energy vehicle battery box in high-strength water environment, and improve the safety and service life of the battery box. The locking device integrates sealing, waterproof, water indication and other functions, which can effectively prevent water from entering the battery box and monitor the water situation of the battery box in real time, providing timely warning for the vehicle owner.

[0024] The main components of the battery box locking device include T-shaped body 1, head 2, rod 3, bolt groove 4, installation groove 5, water sensing block 6, water-sensitive color-changing sticker 7, through hole 8, sensing cavity 9, water blocking cap 10, outer annular protrusion 11, rubber ring 12 and other components. These components work together through precise design and connection to complete sealing, waterproof and intelligent monitoring functions, ensuring efficient work of the battery box in complex environments.

[0025] Firstly, the T-shaped body 1 is the core of the entire locking device, which is made of high-strength steel or aluminum alloy material to ensure its firmness and corrosion resistance. The T-shaped body 1 includes the head 2 and the rod 3, wherein the outer end surface of the head 2 is provided with the bolt groove 4, which is used for connecting with the interface of the vehicle battery box to fix the battery box locking device. The rod 3 is coaxially connected with the head 2 and has a thread, which can be tightly connected with the locking interface of the battery box to ensure the sealing of the battery box.

[0026] The outer end surface of the head 2 is provided with an outer annular protrusion 11. The protrusion is designed to effectively enhance the sealing performance and prevent water from penetrating. An annular rubber ring 12 is fixed to the head 2 to provide a secondary sealing function, further preventing water from entering the battery box through the locking member. The height of the rubber ring 12 is preferably designed to be higher than the outer annular protrusion 11, effectively compressing the locking interface and ensuring the sealing performance of the contact part between the locking member and the battery box.

[0027] The outer side surface of the head 2 also extends radially to form a water-blocking cap 10. The water-blocking cap 10 effectively blocks water from directly contacting the locking member, helping to improve the waterproof performance of the locking member. This design is particularly suitable for situations where the vehicle may encounter splashing water or muddy water during driving, further improving the sealing performance of the battery box.

[0028] The water immersion sensing block 6 is one of the innovative designs of the locking member. It is made of water-resistant rubber material, with excellent water resistance and long-term stability. The water immersion sensing block 6 is fixed in the T-shaped body 1 through interference fit with the installation groove 5, and forms an induction cavity 9 through the spacing fit with the bottom of the installation groove 5. A through hole 8 is provided in the induction cavity 9, which is in communication with the external environment. When the battery box is immersed in water, water will enter the induction cavity 9 through the through hole 8, triggering the monitoring function of the water immersion sensing block 6.

[0029] The water-sensitive color-changing sticker 7 is installed in the sensing block 6. The water-sensitive color-changing sticker 7 can change color according to the degree of water intrusion, providing intuitive visual indication. When the battery box is immersed in water, the water-sensitive color-changing sticker 7 will change color according to the water level and the time of water immersion. The owner or maintenance personnel can judge the water immersion situation of the battery box according to the degree of color change. For example, when the water level rises to a certain extent, the water-sensitive color-changing sticker 7 will change from transparent to blue, and further rise to red, indicating that the water intrusion is getting worse. This allows the owner to discover the water immersion problem of the battery box in time during driving and take appropriate protective measures.

[0030] To ensure the stability and accuracy of the sensing block 6 in long-term use, a drying block is also provided in the induction cavity 9. The drying block is made of high-hygroscopic material, which can effectively absorb the water in the induction cavity and prevent the water from affecting the sensitivity and accuracy of the sensing block 6, ensuring the long-term reliability and stability of the locking member. The setting of the drying block makes the induction cavity 9 maintain a dry environment, further ensuring the accuracy and stability of the water-sensitive color-changing sticker 7.

[0031] The battery box locking device of the present embodiment has the following advantages. First, the use of a multi-layer sealing structure and the design of the rubber ring 12 significantly improves the sealing performance of the battery box, ensuring that water cannot enter the battery box in a water environment, protecting the normal operation of the battery and electronic components. Second, the design of the water sensing block 6 and the water-sensitive color-changing sticker 7 provides an intuitive water intrusion indication function, allowing the vehicle owner to discover water intrusion problems in the battery box in a timely manner and avoid battery damage. Finally, the provision of the drying block ensures that the sensing cavity 9 is dry for a long time, improving the stability and accuracy of the sensing system.

[0032] The specific use scenario is that during the driving of a new energy vehicle, when the vehicle encounters a water accumulation or deep water environment, the locking device can effectively prevent water from entering the battery box and avoid damage to the inside of the battery box. At the same time, the water-sensitive color-changing sticker 7 reflects the degree of water intrusion in real time, and the vehicle owner can observe the degree of water intrusion by observing the color change and take measures such as stopping, checking or repairing in a timely manner to avoid safety problems caused by battery damage.

[0033] Therefore, the battery box locking device of the present embodiment not only ensures the sealing and waterproof performance of the battery box in a water environment, but also provides intelligent water intrusion monitoring and indication functions, improving the safety of new energy vehicles and the service life of the battery.

[0034] Although exemplary embodiments of the present disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included within the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and equivalents of these claims are also included.
