Description

Technical Field

[0001] The utility model relates to the technical field of new energy automobile accessories, in particular to a liquid heater that is quickly connected to a compressor through a fisheye needle. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source or use conventional automotive fuels, adopt new on-board power devices, and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures.

[0003] The compressor of new energy vehicles is an important component in the air conditioning system of new energy vehicles, mainly used for refrigeration. It controls the rotation of the motor through electronic control, drives the compressor through the crankshaft, sucks in low-temperature and low-pressure gaseous refrigerant, compresses it into high-temperature and high-pressure gas, and then cools it into liquid through the condenser and discharges heat.

[0004] Thick film liquid heater is a device that uses thick film heating technology to heat liquid. Thick film heater mainly consists of a flat metal substrate, an electrical insulation layer and a resistive heating track. Its working principle is to heat the liquid by applying a resistive heating track on the metal substrate and using the heat generated by the current passing through the resistor.

[0005] The compressor performs well in automobile air conditioning refrigeration, but has many shortcomings in heating in winter. At present, new energy vehicles generally use a mode in which the compressor and heater are separated for cooling and heating. There are two-in-one heaters with other structures, which all share a shell. This product does not share a shell, and existing products cannot solve the problem of heat loss.

[0006] Therefore, the present application proposes a liquid heater that is connected to the compressor through a fisheye needle, so as to solve the problem mentioned above that the current new energy vehicles generally use a mode in which the compressor and the heater are separated for cooling and heating. Summary of the invention

[0007] The utility model aims to provide a liquid heater which is connected to a compressor by a fisheye needle, so as to solve the problems in the current market raised by the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a liquid heater connected to a compressor quick plug through a fisheye needle, comprising a heater connecting plate, a heat insulating block is installed on the heater connecting plate, and a heat insulating plate is installed on the heater connecting plate, a first fixing hole is opened on the heater connecting plate, a second fixing hole is opened on the heat insulating block, a first through groove is opened on the heater connecting plate, and a heat insulating gasket is arranged on the upper surface of the heat insulating plate;

[0009] A heater intermediate component is installed above the heater connecting plate, a second through slot is opened on the heater intermediate component, a protective cover is installed above the heater intermediate component, a quick-plug connecting plate is installed on the heater intermediate component, and a vertical plate is installed below the quick-plug connecting plate, and a guide column, a first fisheye needle and a second fisheye needle are installed below the vertical plate.

[0010] Preferably, there are multiple insulation blocks and one insulation board. Both the insulation board and the insulation block are fixedly connected to the heater connecting plate.

There are seven insulation blocks in total. The insulation blocks are distributed in a rectangular structure and are each provided with a 0.3mm insulation pad.

[0011] By adopting the above-mentioned structural design, through the design of the insulation block and the insulation board, the liquid heater and the compressor can have a better insulation effect when they are connected, preventing heat from being transferred between the liquid heater and the compressor, and avoiding the liquid heater and the compressor from affecting each other during operation.

[0012] Preferably, a positioning column is installed above the thermal insulation board, and two positioning columns are provided. A through hole is provided on the thermal insulation gasket, and the positioning column can pass through the through hole. The thermal insulation gasket is movably connected to the thermal insulation board.

[0013] With the above structural design, the thermal insulation gasket can be limited by the positioning column, thereby facilitating the installation of the thermal insulation gasket and preventing the thermal insulation gasket from shifting during installation.

[0014] Preferably, a third fixing hole is provided on the intermediate component of the heater, a center line of the third fixing hole coincides with a center line of the second fixing hole, and the second fixing hole and the third fixing hole are connected by a fixing screw.

[0016] Preferably, the second through slot is located directly above the first through slot, and the vertical plate can penetrate the first through slot and the second through slot.

[0017] With the above structural design, when installing the vertical plate on the quick-plug connection plate, the vertical plate is passed through the first through slot and the second through slot, so that the quick-plug connection plate abuts against the intermediate component of the heater.

[0018] Preferably, a positioning hole is provided on the quick-plug connecting plate, and the vertical plate and the quick-plug connecting plate are installed perpendicular to each other.

[0019] With the above structural design, the quick-plug connecting plate and the heater intermediate component can be easily connected and fixed through the positioning holes on the quick-plug connecting plate.

[0020] Preferably, two guide posts are provided, a plurality of first fisheye needles and a plurality of second fisheye needles are provided, and the sizes of the first fisheye needles and the second fisheye needles are different.

[0021] With the above structural design, when the liquid heater is connected to the compressor, the liquid heater is connected to the compressor PCB control board through the guide column, the first fisheye needle and the second fisheye needle. The first fisheye needle and the second fisheye needle are directly inserted into the reserved hole of the PCB and are tightly connected through the fisheye structure, thereby completing the connection between the liquid heater and the compressor. The positioning hole and the guide column can make the first fisheye needle and the second fisheye needle accurately and quickly positioned, and perform a single fixed connection, which greatly reduces the material damage caused by inaccurate positioning and misalignment of the fisheye needle assembly and the PCB board during connection.

[0022] Preferably, a metal structure is provided inside the middle component of the heater, and the cross section of the metal structure is designed in a "J"-shaped structure.

[0023] The above structural design improves the heat dissipation efficiency inside the middle component of the heater.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] By setting the first fisheye needle and the second fisheye needle, the liquid heater and the compressor are designed as a split body, the liquid heater and the compressor are connected by a fisheye structure, a quick-plug connection is made with the PCB board of the compressor, and a two-in-one fixation is performed by screws, thereby realizing one PCB board to control the compressor and the liquid heater.

[0026] It saves installation space inside the car and eliminates a PCB board, making the cost of the overall integration solution more advantageous.

[0027] The heater does not need a PCB control unit, only a heating unit of the heating plate and a water circulation unit formed by the shell. BRIEF DESCRIPTION OF THE DRAWINGS
