Description

 The claimed invention relates to car building, namely to the placement of batteries in car modules.

 A device for installing batteries on a vehicle is known (Russian patent N 1388336, B 60 R 16/04, filed May 16, 1995), containing a car box with a lid, guide rails for rollers, fixed on the bottom of the box and sections of rails mounted on the lid with limiters. A drawer frame is supported on the drawer guides with its rollers, on which a pallet is fixed. Batteries are installed on the pallet, connected to the unit by plates, tightened with studs. Batteries are integrated by interconnects into a battery. The battery is connected to the electric system of the car with wires, which have a margin of length in the form of freely hanging sections to ensure the extension of the frame with the battery.

 For maintenance of the battery, the luggage compartment lid is rotated horizontally. In this case, the other guides are combined in level and direction with the continuation of the fixed guides. The frame extends to touch the end stops. Batteries inspected or replaced. At the end of maintenance, the frame slides into the box for operation.

 In known constructions of cars for fitting into the standard size of rolling stock, the car box is mounted with an offset from the side surface of the car to its middle, and the use of a cover as a base for rotary guides limits the amount of frame travel in the lateral direction. As a result, the complete exit of the battery from under the car is not ensured. Inspecting the batteries remaining under the car is difficult, and replacing at least one battery is only possible after disassembling the entire battery.

 In addition, in order to hold the sliding frame with the battery on the lid, sufficient strength of the box and lid must be ensured. This will make the construction heavier.

 The hanging sections of the wire are not protected from falling under the rollers of the sliding frame and from the possibility of engagement with the elements of the drawer parts when moving the frame.

 A well-known battery container (Russian patent N 2030027, B 60 R 16/04, filed January 9, 1992), comprising a housing with a removable cover, a clamping assembly for pressing the modules to the rear wall of the housing, a battery mount assembly including one installed in the upper part shell frame. The frame, connected by means of locks with a removable cover and by means of hinges with an explosive valve, forms a frame suspended from the carriage with the supporting elements of the body. Transverse rails made in the form of L-shaped traverses are attached to the frames. The horizontal element of the beam is made of a channel, and the vertical element of the beam is a strip welded to the middle of the channel neck. The upper end of the strip is welded to the side of the front of the frame. The side shoulders of the modules are supported with the possibility of sliding on the formed shoulders. The clamping unit is made in the form of a U-shaped locking support pivotally connected by the ends in the base with the frame. Another element of the clamping unit is at least one hinged screw with a wing nut, which is connected by an axis to the traverse. The hinged screw has the ability to engage with the cutout of the U-shaped frame. The module has a plastic detachable casing with side protrusions located at the top of the module. Modules for ensuring their installation and dismantling are pre-assembled in blocks. In the container, each block rests on two adjacent traverses, which are the supporting elements of the frame.

 To detect and replace a faulty battery, remove the cover from the housing, unscrew the wing nuts of the clamping device, extend and disassemble the unit.

 Maintenance of the battery from above through an explosive valve in cramped conditions under the car body is extremely difficult: to replace a faulty battery, for example, it is necessary to disassemble the cell connectors, unscrew the wing nuts, remove and disassemble the unit, replace the battery, then assemble the unit and its connectors.

 The prototype is a battery-driven car module (application of Russia N 96109069/28, B 60 R 16/00), comprising a housing and a roll-out trolley, interconnected by a system of mutually contacting rollers and rails located on the trolley and the housing. The casing is closed at the top with a valve cover, and at the front with a hinged cover with lower guides fixed to it. The trolley is made in the form of a frame and is equipped with elements of insulation, sealing and battery fastening. The upper and lower rails are equipped with extendable parts, which can console extend the drawer rails. The fastening and fixing units of the sliding parts of the upper guides are made in the form of a brace and a groove on the sliding part, rigidly fixed to the guide pin and a support element welded to the body. The fixture for fixing the trolley in the housing is formed by the sliding part of each upper guide and the elements of the fastening and fixing unit of the guides — a longitudinal groove, a groove and an inclined platform of the support element. The sliding parts of each lower rail are connected to respective guide hinges.

 Providing sufficient strength to accommodate the rail supports on the housing and its lid makes their construction heavier. The presence of an additional pair of sliding parts of the rails complicates the design and increases the preparation time of the rails to extend the cart.

 The presence of special elements of the seal and fastening of the batteries also increases the duration and the complexity of maintenance of the battery by the need to disassemble and restore the seal and mount.

 Options 1 and 2. The objective of the proposal is to increase the convenience and reduce the duration and complexity of maintenance of the battery, as well as simplifying the design and reducing the weight of the module.

 Option 1. For this, the inventive module contains a box with a lid, rails fixed on its side walls, supporting a retractable frame, locked with stops, of which the front ones are formed by fastening nodes of retractable rails, fixing elements for their horizontal position and locking elements for their retracted position, battery insulators suspended from the longitudinal beams of a retractable frame. New is that each of these nodes is made in the form of a bracket attached to the guide and (or) to the drawer, connected to the retractable console by means of an earring with vertical and horizontal axes passed through it, pressed to the elastic stop of the retractable frame when the retractable consoles are interlocked, and one of them, with the edge of the box, and one of the fixation elements is made on the undercarriage suspension, the most remote from the earring to the outside.

 The fixing elements are made in the form of a locking longitudinal opening of the suspension and a conical head of a finger mounted with the possibility of interaction with it on a retractable console.

 The suspension is made in the form of a hook spring-loaded to the plane of the car, mounted on an axis in the eyes of the car.

 The locking element is made in the form of an end tooth of the console, with the possibility of dropping into the recess of the other console or coupling it to the edge of the box.

 The elastic element is pressed by the head of the horizontal axis located on the console.

 Option 2. To solve the task, the module contains a box with a lid mounted on its side walls, rails supporting a retractable frame, locked with stops, of which the front ones are formed by fastening nodes of retractable guide rails, elements for fixing their horizontal position and locking elements for their retracted position, battery insulators suspended from parallel beams of a retractable frame. What is new is that the ends of the beams are rigidly connected by crossbars located at the same level with them, the distance between which is equal to a multiple of the size of an elastically compressed insulator made in the form of spring plate parts with flanges of a horizontal saddle that elastically covers a spacer insert provided with a plate U- in the area of the beams a traverse, the linear dimensions of which are selected according to the conditions of the sliding landing of the battery and the location of its center of mass as close as possible to the level of the axes of the beams.

 In addition, the saddle is composed of two brackets with opposing flanges on each of them, and the insert between the beams has counter protrusions forming vertical channels overlapped by brackets.

 As can be seen from FIG. 5, the saddle is composed of four vertical angles with each other forming channels, with a flange on each of them, and the insert has the shape of a rectangular belt covering the battery with a U-shaped traverse.

 The angular size of each individual part of the saddle is larger than the angular size in combination with a spacer insert and a group of insulators installed in the armhole of the frame.

 For compact design, the saddle or insert can be made of sheet metal.

 New is the fact that the box is equipped with a double-link lead carrying an electric wire connected to a sliding frame by a detachable hinge.

 The technical result is expressed in the following.

 Option 1. Pressing the earring to the elastic stop when the consoles interlock with each other and when one of them engages with the edge of the drawer allows you to fix the sliding frame in the drawer.

 The location of the element for fixing the horizontal position of the console on the subcarriage suspension, as far as possible from the earring outward, to the edge of the car, increases the base of the support for the console, the interval of lateral extension of the battery, and also reduces the weight of the console mount.

 The implementation of the attachment point of the retractable consoles in the form of an arm attached to the guide and (or) to the drawer, connected to the console by means of an earring with vertical and horizontal axes passed through it, allows the earring to be used as a clamping element of the elastic stop and as an element of the console extension of the drawer guide.

 Performing the suspension in the form of a hook mounted on an axis in the eyes of the car and spring-loaded to its plane, ensures the performance of the design.

 The implementation of the locking element in the form of an end tooth of the console, having the ability to sink into the recess of the other console or clutch with the edge of the box, will allow you to use the console mount as a lever clip, which facilitates fixing the frame in the box.

 The location of the axis head on the console with the possibility of pressing the elastic stop by the head will ensure the reliability of the engagement of the end tooth with the locking element, and, consequently, the reliability of fixing the frame with the battery in the box.

 Compared with the prototype, the design of the module in this embodiment is simpler, because it has only one pair of guides with retractable consoles.

 Option 2. A rigid connection of the ends of the beams with cross members, the distance between which is a multiple of the size of the elastically compressed insulator, the design of the insulator in the form of spring plate parts with flanges of a horizontal saddle, elastically covering a spacer insert provided with a plate └┘-shaped traverse in the area of the beams, will provide elastic compensation clearances when inserting inserts between parts of the saddle inside the frame opening.

 The choice of the linear dimensions of the spacer according to the conditions of the sliding fit of the battery will allow you to replace any single battery.

 The choice of the linear dimensions of the insert, providing the location of the center of mass of the battery, as close as possible to the plane of the axes / 40 / beams and crossbars / 12 /, will prevent tipping moment on the batteries during inertial loads. This is ensured by the height of the location of the └┘-shaped traverses / 38 / relative to the flanges / 37 /. Due to this, fixing the batteries is simplified and the laboriousness of the module maintenance is reduced.

 The presence of vertical channels formed by the opposing protrusions of the insert, overlapped by brackets, provides condensate drainage through the insulator from the top of the battery / Fig. 4/.

 As shown in FIG. 5, the channels formed by the parts / 33 / of the saddle on the insert belt play the same role.

 The manufacture of a saddle in parts of two obtuse-angled brackets with opposing flanges on each of them ensures that the load is applied from the elastically deformed saddle directly to the corners of the insert, thereby reducing the required wall thickness and insert weight.

 The manufacture of a saddle in parts of four angular elements with flanges on each allows you to use this saddle to install inserts of different sizes, namely with a belt corresponding to the dimensions of the selected type of battery.

 Performing a saddle or insert from a steel plate will allow the insulator to be compact.

 The presence of a two-link carrier that carries the electric wire in the box will exclude damage to it when the frame is extended.

 The presence of a detachable hinge in the connection of the leash with the retractable frame will speed up the replacement of the battery if necessary.

 Option 1. FIG. 1, 2, 6 ... 11. The car battery module contains a box 1 with a lid 2, guides 4 mounted on its side walls 3, retractable consoles 5 and 6 with end stops 7, a retractable frame 8 with front 9 and rear 10 elastic stops and with parallel beams 11 connected at their ends located with them at the same level by the cross members 12, the attachment points 13 of the consoles / Fig. 1 /, fixing elements 14 and 15 of the horizontal position of the consoles, locking elements 16, 17, 18 / tooth, recess, flange / retracted position of the consoles, front 19 and rear 20 limiters of the retracted frame and insulators suspended on longitudinal beams made of sheet material having elastic property in bending. The guides 4 carry a frame 8 mounted on rollers, locked relative to the box of the limiter 19 and 20, interacting with the elastic stops 9, 10. The limiters 19 are formed by attachment points 13, each of which is made in the form of an bracket 21 attached to the guide 4 and / or / box 1 connected to the console through a node 13, consisting of an earring 22 and passed through it vertical 23 and horizontal 24 axes.

 In the example shown in FIG. 1, the earring can interact with the elastic stop 9, for example, by means of a protrusion 25 which is rigidly attached to it when the consoles 5 and 6 are interlocked and, one of them, with the box rim 19.

 The fixing element 14 is made in the form of a longitudinal lock in the suspension 26 mounted on the axis 27 in the eyes of the car 28 and pressed against its plane by a spring 29 or a torsion spring, for example, located on the axis 27.

 For a more rigid fixation of the working position of the console, the eyelet 28, and with it the supporting part 30 of the suspension, are maximally distant from the earring 22 to the outside of the car.

 Another locking element is made in the form of a conical head 15 of the finger 31, rigidly fixed to the console with the possibility of entering the conical head 15 into the locking hole 14 of the suspension 26.

 The locking element is made in the form of an end tooth 16 having the ability to sink into the technological recess 17 of the other console or clutch with the edge 18 of the box under the action of an elastic stop 9, interacting with the head 19 of the horizontal axis 24.

 Option 2. FIG. 1 ... 5. The car battery module, in addition, contains insulators, each made in the form of elastic, for example, fiberglass, plate parts 32 or 33 with flanges 34, which form a horizontal saddle covering the spacer insert 35 or 36 with flanges 37 and в in the area of the beams 11 -shaped plate traverse 38. The linear dimensions of the insert are selected according to the sliding fit of the battery and the location of its center of 39 masses at the level of the axes 40 of the beams 11 / Fig. 3 /.

 In the area of the beams, the corners of the insert 35 or 36 are loaded with elastically pressed elements 41 of the parts 32 or 33 of the detachable saddle / Fig. 4, 5 /.

 Box 35 / Fig. 4 / has opposing protrusions 42, and the saddle is composed of two overlapping protrusions 42 of the parts 32, in the form of plate brackets with opposing flanges 34 on each of them.

 In the example / FIG. 5 / the saddle is composed of four parts 33, having the shape of a vertical angle with a flange 34 on each of them, and the insert 36 is made in the form of a rectangular belt covering the battery with a └┘-shaped traverse 38, fixing the center of mass of the battery 39 relative to the level of the axles 40. Adjacent flanges 34 of the parts 33 to each other, under the flange 37, form a channel that provides condensate drainage from the area of the beams.

 For compactness of the insulator and the entire battery as a whole, the saddle or insert can be made of sheet metal.

 Box 1 is equipped with a supporting electric wire 43 two-link leash 44 connected by a detachable hinge 45 with a retractable frame 8.

 Options 1 and 2. The module operates as follows.

 Between the parallel beams of the sliding frame, a group of insulators is installed in one row with the parts 32 or 33 of the saddle pressed to the inserts 35 or 36. The forces of elastic deformation of the parts of the saddle hold each insert from longitudinal and transverse displacements.

 In the inserts 35 or 36, the batteries are lowered from above and connected to the battery. After the assembly, the frame 8 on the rollers is pushed into the box, the console 5 is turned and hooked with the edge 18 of the box with the end tooth 16, and then the other console 6 is turned and its end tooth 16 is engaged with the recess 17 of the previously fixed console 5. At the same time, the heads 19 performing the role of the front limiters of the transport position of the frame is pressed on the elastic stops 9 and pressed the frame 8 through the elastic stops 10 to the rear stops 20. The teeth 16, thanks to the elastic stops 9, are securely held in engagement with the locking elements 17 and 18.

 To extend the frame, open the cover 2. The end of the console 6 is squeezed away and the tooth 16 is disengaged from the recess 17 of the console 5, after which the console 6 is turned with one hand into the working position and the suspension 26 is moved to the vertical position; then the conical head 15 of the finger is inserted into the locking hole 14 and the console is lowered onto the suspension support part 30.

 Similarly fix the working position of the console 5.

 Full extension from under the wagon of the battery on the console guides provides free access to the batteries for inspection, checking the level and topping up of electrolyte.

 To replace the battery, it is enough to free it from the interelement connectors, remove it from the insert and install a new one. The shape of the insert allows a stuck battery to be planted out of it by applying force directly to its bottom.

 The entire battery is replaced together with the frame after the joint 45 is disconnected.

 The suspension may have vertical projections 47 and 48 on the support part 30, instead of the clutch elements 14 and 15, if its fastening to the carriage is not hinged, but rigid or, at least, without a spring 29.

 During operation, each battery is exposed to inertial forces. Its fixation from displacement and tipping is achieved due to the plate parts 32 or 33 of the detachable saddle having a spring angular size for elastic compensation of the gaps between the corners of the inserts and the walls of the beams 11 and 12, as well as due to the elements 38 and 37 of the inserts that determine the position of the center of mass of the battery relative to the beams 11 and 12.

 As can be seen from FIG. 1, 2, the distance between the cross members 12 is equal to a multiple of the size of the elastically compressed insulator.
