Description
Technical Field
[0001] The utility model relates to the technical field of automotive parts, in particular to a ceramic shell for new energy vehicles. Background Art
[0002] An automotive relay is an electrical device that works based on the principle of electromagnetic induction. Automotive relays are widely used in various parts of automotive circuits, such as engine starters, motors, air conditioning systems, etc. Taking the fuel pump relay as an example, it is the control switch of the fuel pump. However, the coil of the fuel pump relay can only form a circuit through the ground connection point of the electronic control unit when the driving triode in the electronic control unit conducts. Thus, it controls the operation of the fuel pump. When there is an overload or short - circuit phenomenon in the circuit, the relay can automatically cut off the power supply to prevent circuit damage and extend the service life of the equipment. A relay is an automatic control device whose output will change in a jump when the input reaches a certain value. The relays used in the engine compartment of vehicles must be able to withstand the intrusion of sand, dust, water, salt, and oil; the vibration and shock are quite harsh. Usually, a ceramic shell is provided outside the relay to protect it.
[0003] The existing ceramic shell fixes the relay through the internal clamping platform. However, when the ceramic shell is subjected to vibration and shock for a long time, displacement will occur at the positioning part of the ceramic shell, and the relay cannot be effectively limited.

[0020] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0021] Please refer to Figure 1-6 , the present utility model provides a technical solution:
[0022] A ceramic shell for a new energy vehicle, including a placing component 1, the placing component 1 includes a placing shell 11, a ceramic plate 12 is installed inside the placing shell 11, a battery body 4 is placed on the upper surface of the ceramic plate 12, lower positioning slots 13 are opened at the four corners of the ceramic plate 12, a positioning component 3 is fixedly installed inside the lower positioning slots 13, a covering component 2 is movably installed on the upper part of the placing shell 11, the covering component 2 includes a shielding shell 21, upper positioning slots 214 are opened at the four corners of the shielding shell 21, the positioning component 3 is inserted and installed inside the upper positioning slots 214, the positioning component 3 includes a positioning cylinder 31 and a positioning pin 32, the positioning pin 32 is inserted inside the positioning cylinder 31, a clamping sleeve 312 is fixedly installed on the positioning cylinder 31, a first clamping block 313 is fixedly installed inside the clamping sleeve 312, a second clamping block 323 is fixedly installed at the bottom end of the positioning pin 32, and the second clamping block 323 is clamped and fitted with the first clamping block 313.
[0023] In this implementation, the placement shell 11 for placing the component 1 serves as the basic structure of the entire outer shell. It provides sufficient strength and stability to support and protect the internal battery components. The material of the placement shell 11 is selected as a corrosion-resistant ceramic shell. The ceramic plate 12 is an ideal material to protect the battery body 4 from external impacts, high temperatures, and chemical substances. The lower positioning grooves 13 opened at the four corners of the ceramic plate 12 are for cooperating with the positioning component 3 to achieve precise alignment and firm connection between the covering component 2 and the placement component 1, which helps reduce assembly errors and improve the stability and reliability of the overall structure. By inserting the positioning pin 32 of the positioning component 3 into the positioning cylinder 31, a preliminary mechanical connection is formed, facilitating installation and disassembly. A clamping sleeve 312 is installed on the positioning cylinder 31, and a first clamping block 313 is fixed inside it. At the same time, a second clamping block 323 is fixed at the bottom end of the positioning pin 32. When the positioning pin 32 is fully inserted into the positioning cylinder 31, the second clamping block 323 is clamped and fitted with the first clamping block 313, thus achieving a more secure locking, enhancing the stability and safety of the connection, and preventing loosening or falling off caused by vibration or impact. The shielding cover shell 21, as the upper covering part of the battery outer shell, provides additional protection. The upper positioning groove 214 corresponds to the lower positioning groove 13. The upper positioning groove 214 is used to receive the inserted part of the positioning component 3, ensuring that the shielding cover shell 21 can accurately cover the ceramic plate 12 and form a good seal and fixation with the placement shell 11, achieving efficient protection and firm fixation of the battery body 4. At the same time, the requirements in terms of electromagnetic shielding and easy maintenance are considered, which helps improve the safety and reliability of new energy vehicles and extend the service life of the battery.
[0024] Specifically, a second limiting groove 311 is opened at the top of the positioning cylinder 31, and a spring 314 is fixedly installed inside the positioning cylinder 31. The spring 314 is located above the first clamping block 313.
[0025] In this embodiment, the opening of the second limiting groove 311 is to limit or guide the insertion direction of the positioning pin 32, ensuring that the positioning pin 32 can accurately enter the positioning cylinder 31 and cooperate with the first clamping block 313 to prevent the positioning pin 32 from accidentally coming out due to vibration or external forces. The spring 314 is located above the first clamping block 313. When the positioning pin 32 is inserted into the positioning cylinder 31, the spring 314 will be compressed. The positioning pin 32 can have a certain buffering and self-adaptive ability during the insertion process, reducing wear and impact caused by hard contact. When the positioning pin 32 is fully inserted and pushes the second clamping block 323 to be clamped with the first clamping block 313, the elastic force of the spring 314 can help maintain the stability of this clamping state. When disassembly is required, the elastic force of the spring 314 also helps the positioning pin 32 to be smoothly pulled out, increasing the flexibility and durability of the positioning component 3, extending the service life, and also improving the efficiency of assembly and disassembly.
[0026] Specifically, a fixing plate 321 is threadedly connected to the top end of the positioning pin 32. A limiting sleeve 322 is sleeved outside the positioning pin 32, and the limiting sleeve 322 is inserted and installed inside the second limiting groove 311.
[0027] In this embodiment, the fixing plate 321 is fixedly connected to the top end of the positioning pin 32 by threaded connection. This connection method is not only firm and reliable but also convenient for disassembly and maintenance. The main function of the fixing plate 321 is to increase the contact area between the positioning pin 32 and the shielding cover 21, thereby dispersing and bearing the pressure and vibration from the covering assembly 2. This helps to reduce the local stress concentration of the positioning pin 32 and improve its service life. The limiting sleeve 322 is sleeved outside the positioning pin 32 and is inserted and installed inside the second limiting groove 311 at the top of the positioning cylinder 31, restricting the lateral movement of the positioning pin 32 during the insertion process, ensuring that the positioning pin 32 can accurately enter the positioning cylinder 31 and cooperate with the first locking block 313. When the positioning pin 32 starts to be inserted into the positioning cylinder 31, the limiting sleeve 322 first enters the second limiting groove 311, playing a guiding and limiting role. As the positioning pin 32 continues to be inserted, the limiting sleeve 322 slides along the second limiting groove 311 until the positioning pin 32 is completely inserted and locked, improving the accuracy and reliability of positioning, reducing misoperations during the assembly process, and the limiting sleeve 322 also plays a certain buffering role, protecting the positioning pin 32 and the positioning cylinder 31 from wear caused by hard contact.
[0028] Specifically, a lower opening slot 111 is provided on one side of the placement shell 11, and an upper opening slot 211 is provided on one side of the shielding cover 21. The lower opening slot 111 coincides with the upper opening slot 211.
[0029] In this embodiment, the coinciding design of the lower opening slot 111 and the upper opening slot 211 enables operations to be carried out through these two slots when the shielding cover 21 needs to be installed or disassembled, avoiding the disassembly and assembly difficulties that may be brought about by a completely enclosed structure and improving the convenience of maintenance. When the shielding cover 21 completely covers the placement shell 11, the coincidence of the lower opening slot 111 and the upper opening slot 211 can form a continuous sealing surface, helping to reduce the intrusion of external factors such as dust and moisture into the battery through gaps, ensuring the working environment and safety of the battery. The design of the opening slots not only facilitates disassembly and assembly but also can enhance the connection stability between the placement shell 11 and the shielding cover 21 to a certain extent. Through the coincidence of the slots, the two components are in contact and supported at multiple points, reducing the risk of loosening or deformation caused by vibration or impact.
[0030] Specifically, a placement groove 212 and a first limiting groove 213 are provided on the upper surface of the shielding cover 21. Both the first limiting groove 213 and the upper positioning groove 214 are sleeved and installed outside the battery body 4.
[0031] In this embodiment, the placement groove 212 is a groove specifically designed for the battery body 4, and its shape and size are matched with those of the battery body 4 to ensure that the battery can be stably placed under the shielding housing 21. This not only provides physical support but also reduces the shaking and displacement of the battery during driving. Through the precisely designed placement groove 212, the contact between the battery body 4 and the shielding housing 21 is closer, which helps to improve the overall stability and safety. Through the combined action of the placement groove 212, the first limiting groove 213, and the upper positioning groove 214, the battery body 4 is fully protected and firmly fixed in the new energy vehicle.
[0032] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
