BEST IMPLEMENTATION

The proposed electrical equipment

the car compartment (box) with the housing 1 in the form of a frame with a hinged front cover 2, and the walls of the housing 1 of the car compartment have ventilation openings. In the lower part of the housing 1, roller guides 3 are mounted, having rollers 4, on which are mounted 6. On their flat guides 5, the hinged front cover 2 is provided with roller guides 7, similar to roller guides 3. Each roller guide 7 of the cover consists of two parts: the fixed part

7.1 and the folding part 7.2. The fixed roller guide 7.1 is rigidly fixed to the hinged front cover 2 and pivotally connected to the folding roller guide

7.2 using the hinge 8 with the ability to install and fix the folding guide 7.2 in the unfolded and folded states. A stop 9 is rigidly fixed at the other end of the folding roller guide 7.2. The rollers 4 of the folding 7.2 and the fixed 7.1 guides are mounted in such a way that in the folded state of the sliding guides 7.2, its rollers 4 occupy a position between the rollers 4 of the fixed guide 7.1, which ensures compactness. The devices for fixing the folding roller guides 7.2 in the unfolded state consist of stops 10 with through holes 11 mounted on the hinged front cover 2 and the corresponding holes 12 in the folding guides 7.2. In the stops 9, a hole 13 is also made and in the fixed guides 7.1, the counter holes 14, and holes II and 12,

13 and 14 are aligned. Fastening and fixing is carried out by inserting the pins 15 into the holes 11 and 12 or 13 and 14, respectively. The distance between the stops 10 corresponds to the width of the folding roller guide 7.2. Roller guides 3 and 7 together constitute single roller guides with rollers 4 to ensure rolling module 6 on it on its flat guides 5. Module 6 is equipped with elements for fixing 16 and fastening 17 in the housing 1 of the car compartment. On the side walls of the module in the housing 1, output connectors 18 of electrical equipment units located inside the module 6 are installed, and the cable length is selected sufficient to ensure electrical connection of the module 6 in the position extended to the cover 2. Radiators 19 are installed on the rear, front and side walls of module 6, and on the upper wall of module 6 there is a top cover 20 made reclining with a seal around the perimeter. The radiator 19 on the rear wall of module 6 is dimensioned so that it protrudes from the housing 1 of the car compartment in the retracted position of module 6. In the lower part of the housing 1 of the car compartment there are connected to the common car ventilation system

air ducts 21 for supplying cooling air to the radiators 19, and the front radiator is equipped with fans 22 for removing heat from it. The bottom of module 6 is made in the form of a tetrahedral inverted pyramid, at the top of which there is an opening 23, above which in the fixation element consisting of a spring 24, a plate 25 with cut ears is fixed so that there are openings 26 between the corners of the plate and the bottom.

It is possible to execute module 6 from separate sections 27 and 28, separated by air gaps.

DEVICE OPERATION

The operation of the proposed module is considered in two positions in the operating state and in the maintenance mode.

During operation, module 6 is located inside the housing 1 of the car compartment (box). In this case, the rear radiator 19 protrudes from the housing 1 and an unbroken heat sink from it is carried out under the air flow under the car. The module 6 is fixed in the housing 1 by the fixing element 16. The module 6 is fastened in the retracted position by means of the fastening elements 17. The modules 6 are connected by electrical connectors 18 to the electrical system of the car. The heat sink from the radiators 19 on the front wall of the module 6 is carried out using fans 22 or from the general-car ventilation system for electrical equipment by supplying air through the ducts 21. The module 6 is dust and water tight due to the seals between the radiators 19, the upper cover 20 and the housing of the module 6, respectively. The hinged front cover 2 of the car compartment is in a closed state, while the module 6 is mounted with its flat guides 5 on the rollers 4 of the roller guides 3 of the housing 1 and fixed. Folding roller guides 7.2 of the cover 2 are folded and secured with pins 15 by inserting them into the holes 13 and 14.

In maintenance mode, the hinged front cover 2 is folded to a horizontal position. The pin 15 is removed from the openings 13 and 14, releasing the folding roller guides 7.2, which are folded open and fastened with the pins 15 by inserting them into the holes 11 and 12. The fastening elements 17 are disconnected. Module 6 is first pulled by the roller guides 3, with the exit to the cover 2 - by

7 roller guides roll out a day of work. The length of the cable of the electrical connectors 18 provides the connection of the electrical equipment of the module 6 to the electric network of the car in a fully extended position to the stops 9, which serve as limiters. If it is necessary to repair or maintain the electrical equipment of module 6, access to it is provided by opening the top cover 20 or radiators 19. After the work is completed, the module 6 is returned to its original state in the reverse order: the radiators 19 are closed, the top cover 20, the module 6 slides into the housing 1 and fastened by the fastening element 17, the pin 15 is pulled out, folding roller guides 7.2 are folded and fastened in the folded state by the pin 15, the hinged front cover 2 is closed. Accumulating inside m Having blown 6, condensate when draining on its bottom through the openings 23 and 26 is removed from module 6. At the same time, the openings 23 and 26 together with the plate 25 represent the maze to prevent dust and dirt from entering the module 6. If necessary, the maze is cleaned of dust and dirt after removal plate 25 of the springs 24 of the locking element.

When electrical equipment with significant heat dissipation is installed in module 6, the sectional design of the module (sections 27.28) allows you to separate the mesh-separating elements from the rest of the electrical equipment of the module with intersectional air gaps, which ensures normal temperature operation of the electrical equipment as a whole.

From the above it is seen that the introduction of these differences allows you to roll module 6 out of the housing 1 to a distance sufficient for convenient maintenance of the electrical equipment installed in module 6, to provide dust and water tightness of module 6 with simultaneous continuous drain removal, and generally to increase

reliability and ease of use, thereby solving the problem.
