Description

Technical Field

[0001] The utility model relates to the technical field of engine parts, in particular to an electric heating ceramic carrier. Background Art

[0002] In the field of automotive exhaust treatment, automotive electric heating ceramic substrates are widely used. Electric heating ceramic substrates typically consist of a ceramic disc and connected components such as wires. Their normal operation is crucial to the stability and environmental performance of automotive systems. However, existing electric heating ceramic substrates have some problems.

[0003] First, in terms of the installation and removal of ceramic discs, the existing technology often adopts a more complicated fixing method, for example, fixing the ceramic disc by multiple bolts or complex snap-on structures. This installation method is extremely inconvenient when the ceramic disc needs to be maintained or replaced. Technicians need to spend a lot of time and energy to disassemble and reinstall it, which increases maintenance costs and time costs. In addition, for the connection part between the wire and the ceramic carrier, the existing technology lacks effective wire fixing measures after inserting the wire and before performing the soldering operation. During operation, the wire is easy to fall off from the connection position, which brings great inconvenience to the subsequent welding work. If the wire falls off multiple times before soldering, it may affect the connection stability between the wire and the ceramic carrier, and thus affect the heating effect and reliability of the electric heating ceramic carrier. Utility Model Content

[0004] In view of the above, the purpose of the present invention is to provide an electric heating ceramic carrier to address the problems raised in the above background technology.

[0005] An electric heating ceramic carrier in this scheme includes a mounting plate, a ceramic plate, and a mounting portion. The ceramic plate is fixedly connected to the inside of the mounting plate. The mounting portion is located below the mounting plate and the ceramic plate. Four clamping mechanisms are equidistantly arranged on the side of the ceramic plate. Two self-locking mechanisms are fixedly connected to the top of the ceramic plate. Four interlocking sleeves are equidistantly arranged on the side of the mounting plate. Four locking plate cavities are equidistantly arranged on the side of the mounting plate. The four interlocking sleeves correspond to the four locking plate cavities one by one and are fixedly connected.

[0006] Furthermore, a heating wire is fixedly connected to the bottom of the ceramic disk, a wiring portion is fixedly connected to the heating wire, and an electric connection portion is fixedly connected to the top of the ceramic disk, and the electric connection portion is fixedly connected to the self-locking mechanism.

[0007] Furthermore, four equidistant fixing blocks are fixedly connected to the top of the mounting portion, and fastening holes are provided on the four fixing blocks.

[0008] Furthermore, the clamping mechanism includes a clamping cavity and a clamping hole. The inner surface of the clamping cavity is slidably connected to a clamping slide. A clamping spring is fixedly connected between one side of the clamping slide and the inner wall of the clamping cavity. The other side of the clamping slide is fixedly connected to a clamping column. The clamping cavity and the clamping hole are opened inside the ceramic disk, and the clamping column is slidably connected to the inner wall of the clamping hole.

[0009] Furthermore, the self-locking mechanism includes a self-locking cavity, two self-locking plates are hinged on the left inner wall of the self-locking cavity, a spring block is fixedly connected to the left inner wall of the self-locking cavity, a self-locking spring is fixedly connected between the spring block and the self-locking plate, a limiting block is fixedly connected to the right inner wall of the self-locking cavity, and a contact groove is provided on the right inner wall of the self-locking cavity.

[0010] Furthermore, a fastening fitting hole is provided on the fitting sleeve, the fitting sleeve is matched with the fixing block, and the fastening fitting hole is matched with the fastening hole.

[0011] Furthermore, a snap-fitting adapting hole is provided on the lock disk cavity, the snap-fitting adapting hole is adapted to the snap-fitting column, a disassembly sliding groove is provided on the lock disk cavity, and a disassembly sliding plate is slidably connected to the lock disk cavity.

[0012] Beneficial effect: By setting up a clamping mechanism, when the ceramic disk needs to be installed and disassembled for maintenance, the clamping column can be aligned with the lock disk cavity position. The clamping column has a round head and is pressed toward the inside of the installation disk to retract a part of the clamping cavity until it passes through the fastening engaging hole on the engaging sleeve and extends due to the elastic potential energy of the clamping spring to complete the positioning. The installation is simple, and only the ceramic disk needs to be pressed. The same is true for disassembly, and only the clamping column needs to be pressed. The convenient installation and disassembly method of the ceramic disk greatly improves the maintenance efficiency. During the life cycle of the automotive electric heating ceramic carrier, when the ceramic disc fails or requires regular maintenance, maintenance personnel can quickly remove it. Compared with traditional complex installation and removal methods, this can significantly shorten maintenance time and reduce vehicle downtime, thereby improving the overall efficiency and economic benefits of the vehicle. A self-locking mechanism is also provided to prevent the connection wire from falling off. When the connection wire is inserted into the self-locking cavity, the self-locking spring is compressed and the self-locking plate rotates. Once the connection wire is inserted deep into the self-locking cavity, the self-locking plate, due to the elastic potential energy of the self-locking spring, presses the connection wire into the contact groove, energizing it. The contact groove and the connection part are electrically connected. The further the connection wire is pulled outward, the tighter the contact wire is due to the angle of the self-locking plate, making it less likely to fall off. Preventing the wire from falling off between insertion and soldering significantly improves the stability and reliability of the wire connection. This makes the connection process between the wire and the ceramic carrier smoother and reduces the possibility of loosening or damage to the connection point caused by repeated wire falling off. Stable wire connections can ensure stable current transmission of the electric heating ceramic carrier during operation, thereby achieving a uniform and stable heating effect, and improving the performance and service life of the electric heating ceramic carrier in the entire automobile exhaust treatment process.

[0022] A fastening fitting hole 601 is provided on the fitting sleeve 6, the fitting sleeve 6 is adapted to the fixing block 301, the fastening fitting hole 601 is adapted to the fastening hole 302, a snap-fit fitting hole 701 is provided on the lock disk cavity 7, the snap-fit fitting hole 701 is adapted to the snap-fit column 404, a disassembly groove 702 is provided on the lock disk cavity 7, and a disassembly slide 703 is slidably connected to the lock disk cavity 7.

[0023] The ceramic disc 2 is a multi-layer composite structure. The inner layer utilizes a high-purity, high-density alumina-zirconia composite ceramic to improve heat transfer and heat carrying capacity. The outer layer utilizes a ceramic material doped with specific rare earth elements (such as yttrium and cerium). The addition of rare earth elements improves the ceramic's toughness and thermal shock resistance. The mounting portion 3 is part of the catalyst. During installation, the mating sleeve 6 is aligned with the fixing block 301 on the mounting portion 3. A fastening screw is then threaded through the fastening hole 302 and into the fastening mating hole 601 to complete the device's secure installation.

[0024] Reference Figures 1 to 3 The clamping mechanism 4 includes a clamping cavity 401 and a clamping hole 405. The inner surface of the clamping cavity 401 is slidably connected with a clamping slide 402. A clamping spring 403 is fixedly connected between one side of the clamping slide 402 and the inner wall of the clamping cavity 401.

[0025] By setting up the clamping mechanism 4, when the ceramic disk 2 needs to be installed and disassembled for maintenance, the clamping column 404 can be aligned with the position of the lock disk cavity 7. The clamping column 404 is a round head, which is pressed toward the inside of the installation disk 1 to retract a part of the clamping cavity 401 until it passes through the fastening engaging hole 601 on the engaging sleeve 6 and is extended due to the elastic potential energy of the clamping spring 403 to complete the positioning.

After the connecting wire is inserted deep into the self-locking cavity 501, the self-locking plate 502 presses the connecting wire into the contact groove 506 due to the elastic potential energy of the self-locking spring 504 and energizes the wire. The contact groove 506 is electrically connected to the power connection part 203, and the more the connecting wire is pulled outward, the tighter the contact of the self-locking plate 502 with the power connection part 203 will be due to the angle, making it less likely to fall off.

[0028] Working principle: By setting the clamping mechanism 4, when the ceramic disk 2 needs to be installed and disassembled for maintenance, the clamping column 404 can be aligned with the lock disk cavity 7 position. The clamping column 404 is a round head, which is pressed into the inside of the installation disk 1 to retract the clamping column 404 into a part of the clamping cavity 401 until it passes through the fastening interlocking hole 601 on the interlocking sleeve 6. Due to the elastic potential energy of the clamping spring 403, the clamping position is completed. The installation is simple, just press the ceramic disk 2. The same is true for disassembly, just press the clamping column 404. At the same time, A self-locking mechanism 5 is provided to prevent the connecting wire from falling off.
