Description

Technical Field

[0001] The utility model relates to the technical field of automotive compressors, and particularly relates to a thick film heating plate assembly for an automotive compressor. Background Art

[0002] At present, thick film heating technology has been rapidly applied in the field of new energy vehicles, and the development of the automotive industry pays more and more attention to integration and modularization. Therefore, according to the automotive design requirements, it is necessary to integrate the water heating air conditioner and the automotive refrigeration compressor together to reduce the mass of the whole vehicle and save its internal space. The thick film heater has the advantages of small volume and high efficiency. When the thick film heater is applied in an automotive compressor, the metal terminal connected to the PCB board of the thick film heater is usually welded and fixed to the pad of the thick film heating plate. The metal terminal is a metal conductive sheet. Therefore, there will be a small amount of internal stress at the welding joint between the metal terminal and the pad. During the operation of the compressor inside the vehicle, vibrations will occur. In the case of long-term vibrations and bumps, there is a risk of cracking and open circuit at the welding joint between the metal terminal and the pad of the thick film heating plate. Summary of the Invention

[0003] In order to solve the problem that the welding joint between the metal terminal and the pad of the thick film heating plate in the prior art is prone to cracking and open circuit, the utility model provides a thick film heating plate assembly for an automotive compressor. A flexible wire is used for transition between the conductive part and the pad of the thick film heating plate, which can effectively absorb the displacement generated due to vibrations and bumps, and avoid the phenomenon of cracking and open circuit at the welding joint between the pad of the thick film heating plate.

[0004] In order to achieve the above purpose, the technical solution of the utility model is: a thick film heating plate assembly for an automotive compressor, including a thick film heating plate and pads arranged on the thick film heating plate. An installation seat is arranged on the thick film heating plate, and a plurality of conductive components are arranged at intervals on the installation seat. The conductive components are connected to the pads of the thick film heating plate and the PCB board of the thick film heater, and play a role in delivering current to the thick film heating plate. The installation seat serves the purpose of assembling the conductive components.

[0005] The conductive component includes a conductive part and a flexible wire. The conductive part is arranged on the installation seat. One end of the flexible wire is connected to the conductive part, and the other end is connected to the pad or the welding part on the pad. The conductive part is used for connecting to the PCB board of the thick film heater. A flexible wire is used for transition between the conductive part and the pad of the thick film heating plate, thereby avoiding the phenomenon of cracking and open circuit at the welding joint between the pad of the thick film heating plate.

[0006] Further, a plurality of substrates are arranged around the thick film heating plate, and through holes are formed in each substrate. The substrates play a role in connecting the installation seat and the flow channel plate of the thick film heater.

[0007] Furthermore, isolation plates are arranged at intervals on the top of the mounting base. The isolation plates are located between two adjacent conductive components. Both the mounting base and the isolation plates are made of insulating materials. The isolation plates play a role in separating adjacent conductive components and improve safety.

[0008] Furthermore, the conductive member is a conductive sheet. A plurality of strip-shaped holes matching the conductive sheet are formed in the mounting base. The conductive sheet is embedded inside the strip-shaped holes and both ends thereof pass through the mounting base. The purpose is to facilitate the connection of the conductive sheet to the flexible wire and the thick film heater PCB board.

[0009] Furthermore, one end of the flexible wire is fixedly welded to the upper end of the conductive sheet, and the other end is fixedly welded to the pad. The flexible wire cooperates with the conductive sheet and the pad to convey current to the thick film heating plate.

[0010] Furthermore, the welding member is an L-shaped conductive sheet. The L-shaped conductive sheet is fixedly welded to the pad. One end of the flexible wire is fixedly welded to the upper end of the conductive sheet, and the other end is fixedly welded to the L-shaped conductive sheet. The flexible wire cooperates with the conductive sheet and the L-shaped conductive sheet to convey current to the pad. At the same time, the flexible wire absorbs the displacement generated due to vibration and bump, avoiding the welding joint between the L-shaped conductive sheet and the pad from cracking and breaking.

[0011] Furthermore, a strip-shaped opening for the vertical part of the L-shaped conductive sheet to pass through is formed in the mounting base. The width of the strip-shaped opening is greater than the thickness of the vertical part of the L-shaped conductive sheet. The purpose is to facilitate the L-shaped conductive sheet to pass through the mounting base and be connected to the flexible wire.

[0012] Furthermore, a stepped platform is arranged at the bottom of the mounting base. The height of the stepped platform is the same as the thickness of the thick film heating plate, so as to facilitate the installation of the mounting base on the thick film heating plate.

[0013] Furthermore, an arc-shaped platform communicating with the stepped platform is also arranged at the bottom of the mounting base. The height of the arc-shaped platform is the same as the height of the stepped platform and the thickness of the substrate. The arc-shaped platform matches the substrate. The purpose is to facilitate the installation and fixation of the mounting base on the thick film heating plate.

[0014] Furthermore, a screw groove corresponding to the through hole is formed at the arc-shaped platform. A bolt is arranged at the screw groove. The mounting base is fixedly arranged on the substrate through the bolt. The mounting base is detachably installed on the substrate through the bolt, so as to facilitate the disassembly and replacement of the mounting base.

[0015] Through the above technical solutions, the beneficial effects of the present utility model are as follows:
