For solving above-mentioned technical problem, this utility model is achieved through the following technical solutions:
One is applied to pure electronic entire car controller high-temperature circulation test device, including high low temperature cycles test case, controls wire harness and load cabinet, described high low temperature cycles test case and load cabinet by controlling wire harness connection.
Wherein, described high low temperature cycles test case is used for placing controller, fills Φ 140mm test cable aperture, by one-stage control wire harness, receive in load cabinet on the left of described high low temperature cycles test case.
Further, described load cabinet is made up of load box, being provided with Switching Power Supply, enamelled resistor, auxiliary reclay, display lamp and fan on described load box, described relay is for the work of analog switch amount, and enamelled resistor is used for simulating step electric machine and shift motor work.
Further, described load box is divided into upper and lower two-layer, and auxiliary reclay is in lower floor, and enamelled resistor is on upper strata.
Further, described load box is 9.
Further, described enamelled resistor is with the power resistor of one layer of enamel powdered frit of its outer surface sintering after alloy resistance wire coiling, have high stability, in high precision, the feature such as noise is low, high-power, high temperature resistant.
Further, electromagnetic relay selected by described auxiliary reclay.
Further, described electromagnetic relay is made up of electric magnet, armature, spring leaf, contact.
Further, described high low temperature cycles test case divides four layers.
Compared with prior art, superior effect of the present utility model is in that:
(1) entire car controller high temperature aging test box adopts the use ambient 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, can at utmost mate the interface function of entire car controller, verify the most full pin, ensure that the generally applicable property of described entire car controller high temperature aging test box, it is to say, the entire car controller after high temperature ageing can be used in any different project required.
(3) program that the entire car controller burning carrying out high temperature ageing is different can be carried out different test modes and reaches specific purpose by entire car controller high temperature aging test box.
(4) front panel of the load cabinet of entire car controller high temperature aging test box is equipped with display lamp, whether can directly display entire car controller at normal operation; There is real-time and observability.
Accompanying drawing explanation
Fig. 1 is applied to the outline drawing of pure electronic entire car controller high-temperature circulation test device described in being;
Fig. 2 is the structural representation on the internal upper strata of load box in Fig. 1;
Fig. 3 is the structural representation of the internal lower floor of load box in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described in further detail.
As it is shown in figure 1, be the outline drawing of load box. Front panel placed the display lamp 1 of corresponding auxiliary reclay, in order to observe whether entire car controller whether normal operation or relay damage and need to change. Being divided into two-layer inside load box, as shown in Figures 2 and 3, it is contemplated that layout and heat radiation, relay 5 is placed by lower floor, and the enamelled resistor 4 that caloric value is big 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 4,2 line banks 3 of 10 enamelled resistors and 2 Switching Power Supplies 2. Enamelled resistor works mainly for simulated machine, it is necessary to considers heat radiation, need to consider spacing when therefore putting. 2 Switching Power Supply respectively 12V and 24V power supplys, basic load provides power supply for detected entire car controller, enamelled resistor and auxiliary reclay. The effect of line bank electrification streaming, 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 main what place is auxiliary reclay 5, in order to simulate entire car controller switching value whether normal operation. Because an entire car controller has multi-way switching values control, the amount of the auxiliary reclay therefore used is also very many, it is contemplated that marshalling, installation are unloaded conveniently, are each attached on special relay guide rail by all relays. Selecting 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 controlling wire harness, high/low temperature alternation case and load cabinet are connected, then power supply is being accessed to load cabinet, the on and off switch of each load box that still closes, experiment can be started.Whole process is without artificial participation, full-automation experiment, but must assure that in high temperature ageing process that people is near aging laboratory, checks that every 2 hours whether a senile experiment room temperature is normal. After eight hours, degradation terminates, and takes out all entire car controllers, carries out next stage and tests.
This utility model is not limited to above-mentioned embodiment, and when without departing substantially from flesh and blood of the present utility model, any deformation that it may occur to persons skilled in the art that, improvement, replacement each fall within scope of the present utility model.
