Description
Technical field
The present invention relates to a kind of high-temperature circulation test device, particularly relate to one and be applied to pure electronic entire car controller high-temperature circulation test device.
Background technology
Pure electric automobile has started to enter the industrialization stage in China, and governmental support dynamics is very large.Pure electric vehicle controller is the core component of vehicle control system of pure electric vehicle, and to the normal traveling of automobile, Brake energy recovery, network management, fault diagnosis filter, monitors that the functions such as vehicle-state play a part very crucial.Entire car controller is placed in vehicle body, the motor feels hot or ambient temperature all will make entire car controller be operated in hot environment, can temperature when the object of entire car controller high temperature ageing case simulates use exactly, detect entire car controller and normally work in different temperatures environment.
Entire car controller is the brain of car load, operationally if there is problem, is breakneck for driving, and entire car controller high temperature ageing device is exactly get rid of the possibility that temperature makes it be interfered to the full extent.In prior art, there is high temperature ageing case in a lot of existing producer, also very universal on the market, but function is fairly simple.Seldom have the high-temperature circulation test device of special pure electronic entire car controller, do not have load and switching value can normally work to detect entire car controller, can not simulated driving time functional requirement.
Summary of the invention
In order to overcome defect of the prior art, the object of the invention is to propose one and being applied to pure electronic entire car controller high-temperature circulation test device.Described test unit can either simulate the operating ambient temperature of entire car controller; Intuitively can also reflect whether entire car controller can normally work in real time, and once can carry out polylith entire car controller circuit board high-temperature circulation test, work efficiency is high.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
One is applied to pure electronic entire car controller high-temperature circulation test device, comprises high low temperature cycles test case, controls wire harness and load cabinet, and described high low temperature cycles test case is connected by controlling wire harness with load cabinet.
Wherein, described high low temperature cycles test case, for placing controller, fills Φ 140mm test cable aperture, by one-stage control wire harness, receives in load cabinet on the left of described high low temperature cycles test case.
Further, described load cabinet is made up of load box, described load box is provided with Switching Power Supply, enamelled resistor, auxiliary reclay, pilot lamp and fan, described relay is used for the work of analog switch amount, and enamelled resistor is for simulating step electric machine and shift motor work.
Further, described load box is divided into two-layer up and down, and auxiliary reclay is in lower floor, and enamelled resistor is on upper strata.
Further, described load box is 9.
Further, described enamelled resistor sinters the power resistor of one deck enamel powdered frit with its outside surface after alloy resistance wire coiling, has the features such as high stability, high precision, noise are low, high-power, high temperature resistant.
Further, electromagnetic relay selected by described auxiliary reclay.
Further, described electromagnetic relay is made up of electromagnet, armature, spring leaf, contact.
Further, described high low temperature cycles test case divides four layers.
Compared with prior art, superior effect of the present invention is:
(1) entire car controller high temperature aging test box adopts the environment for use temperature of entire car controller in high low temperature cycles test case simulated driving process, and temperature changes according to certain rules.
(2) in entire car controller high temperature aging test box, load cabinet and vehicle control unit controls wire harness are self-control, at utmost can mate the interface function of entire car controller, verify the most full pin, what ensure that described entire car controller high temperature aging test box can versatility, that is, the entire car controller after high temperature ageing can be used in the project of any difference requirement.
(3) program that entire car controller high temperature aging test box can be different to the entire car controller burning carrying out high temperature ageing is carried out different test modes and is reached specific object.
(4) front panel of the load cabinet of entire car controller high temperature aging test box is equipped with pilot lamp, whether directly can show entire car controller in normal work; There is real-time and observability.
Accompanying drawing explanation
Fig. 1 for described in be applied to the outside drawing of pure electronic entire car controller high-temperature circulation test device;
Fig. 2 is the structural representation on the inner upper strata of load box in Fig. 1;
Fig. 3 is the structural representation of the inner lower floor of load box in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
As shown in Figure 1, be the outside drawing of load box.Front panel placed the pilot lamp 1 of corresponding auxiliary reclay, whether normally work in order to observe entire car controller or relay whether damage need change.Load box inside is divided into two-layer, as shown in Figures 2 and 3, considers layout and heat radiation, and relay 5 is placed by lower floor, and the large enamelled resistor 4 of thermal value is placed on upper strata.
Fig. 2 is the upper strata schematic diagram of entire car controller high temperature ageing case load box, is made up of 10 enamelled resistors, 4,2 line banks 3 and 2 Switching Power Supplies 2.Enamelled resistor, mainly for simulated machine work, needs to consider heat radiation, need consider spacing when therefore putting.2 Switching Power Supplies are respectively 12V and 24V power supply, and basic load provides power supply for detected entire car controller, enamelled resistor and auxiliary reclay.Line bank plays current delivery, makes wiring attractive in appearance, easy to maintenance.
Fig. 3 is lower floor's schematic diagram of entire car controller high temperature aging test box load box, and whether what mainly place is auxiliary reclay 5, normally work in order to simulate entire car controller switching value.Because an entire car controller has multi-way switching values to control, the amount of the auxiliary reclay therefore used is also very many, considers marshalling, installs and unload conveniently, be all fixed on special relay guide rail by all relays.Select electromagnetic relay when load box makes, relay and base can separate, and facilitate later period maintenance to change.
Concrete, when carrying out entire car controller high-temperature circulation test, first by the burning program tested specially to entire car controller, and put into high low temperature cycles test case, open high low temperature cycles test case power supply, set desired parameters, with control wire harness, high/low temperature alternation case is connected with load cabinet, then accessing power supply to load cabinet, the power switch of each load box that still closes, experiment can started.Whole process is without the need to artificial participation, and full-automation is tested, but must ensure people in high temperature ageing process near aging laboratory, checks that whether a senile experiment room temperature is normal every 2 hours.After eight hours, aging test terminates, and takes out all entire car controllers, carries out next stage and tests.
The present invention is not limited to above-mentioned embodiment, and when not deviating from flesh and blood of the present invention, any distortion that it may occur to persons skilled in the art that, improvement, replacement all fall into scope of the present invention.
