Description

DESCRIPTION

BRIEFCASE WITH CHARGING CABLE FOR ELECTRIC CARS

AND OTHER VEHICLES

Technical object of the invention

The present invention describes a special portable casing that contains a connection cable of those necessary to recharge car batteries or any other electric vehicle. It has standardized connectors and is designed to be able to be attached to the vehicle, somewhere high or where it is comfortable, without the cable getting dirty, by making contact with the ground, or being damaged as a result of friction, being designed so that both the connector that goes to the power pole and the one that goes to the vehicle are removable and easily manageable. The total length planned for the cable is about five meters, having a section of about four meters of smooth reelable cable and another section of one meter of extensible spiral cable. Other embodiments are also presented, admitting the invention any other length of cable with the consequent repercussion in the size of the case. The cable has a locking device and a recovery spring that facilitates its collection once used.

Technical field to which the invention relates

The invention that is presented affects the Sector of Miscellaneous Industrial Techniques, Transportation, within the chapter of Transportation or Maintenance in relation to Vehicles in general. It also affects the Electricity Sector Chapter on Capture of Electrical Energy of the International Patent Classification (CIP), directly affecting the automotive industry or any other vehicle equipped with battery-powered motors with regard to accessories for recharging.

Background of the invention

As far as electric cars are concerned, they are in full development and currently, most brands have prototypes or models in operation. The brands that are not yet in that phase are preparing the projects for their new models, since it is evident that the stage of the conventional internal combustion engine is running out Although it cannot yet be said that we are in the full stage of the electric car, a stage that we could call a transition is being recorded at this time, marked by the existence of a great variety of hybrid technology cars that combine the electric motor with the one powered by fuels. fossils.

Parallel to the development of electric vehicles, new accessories have emerged, totally essential, with specific characteristics, of which there are hardly any precedents. One such accessory is the one described as the object of the present invention relating to the recharging cable for power batteries.

However, since it is something essential, some solutions are already known, registered by some brands, which we quote below:

ES-1106730 U Electric vehicle charging system

ES-1189558 U Charge extension cable for electric car

ES-2380858 A1 Electric vehicle charging system in parking garages

communities

ES-2840069 T3 Charging connector for electric cars and their manufacture

The first refers to a recharging device to be installed in community garages, its characterization being the use of a special processor whose hardware is free.

The second describes an extension cable with intermediate plugs, an electromagnetic protection switch and a meter.

The third is a charging device for community garages where each garage space has a plug whose consumption is charged to the meter of the house of the owner of the space.

The fourth cited describes a charging connector and the procedure for its manufacture and assembly.

Although one of them refers to the cable itself, it is not close to the invention that is now presented. In addition, cable solutions are known that are placed at the charging points and are hung from hooks in a disorderly manner so that some section remains on the ground. It is also known a charging cable multipurpose, announced by the German firm Bosch, which focuses its advantages on incorporating electrical protection means into the charging connectors against possible excessive heating and the means of measurement and control.

With regard to vehicles in the field of nautical and others, in full development and transformation, such as bicycles, motorcycles, scooters, wheelbarrows, chairs for disabled people or any other, the set of advantages that it provides is also applicable the invention although, in each case, its incidence is greater or lesser.

In view of this background, the inventors of what is presented in this document have conceived an accessory in the form of a casing or portable briefcase where a recharging cable is housed with the connectors required to be plugged into the vehicle and into the charging post. recharge, as explained in the subsequent sections. As there is no known precedent that resolves the problem in the way proposed, the inventors consider that the invention includes the novelty characteristics required for its registration.

Summary description of the invention

As previously indicated, the invention refers to a special, portable case that contains a connection cable of those necessary to recharge the power batteries of any type of electric vehicle.

The invention of the invention has been conceived after analyzing the existing solutions on the market which, in relation to the charging cable, present a series of disadvantages that are indicated below:

The cable collects dirt from the ground where it can be impregnated with a large number of viruses and bacteria.

The collected dirt passes into our hands as it is essential to handle the cable.

Any carelessness during handling can cause staining our clothes.

The dirt on the cable can stain the vehicle that we are charging.

The cable can cause scratches on the bodywork. In case of rain, these drawbacks are accentuated, making handling and collecting the cable unpleasant.

- Since the cable is dangling during recharging, it can be the cause of trips whether the operation is done on street poles or in the home garage, in a marina or in private homes.

The time spent on the connection is minimized.

It is normal to carry the cable out of the bag and badly coiled causing disorder in cabinets, containers or trunks and taking up more space than necessary.

In view of these drawbacks, the advantages provided by the present invention are easily deduced, according to which the cable is well protected inside the case, its use does not imply contact with the ground and its collection is simple and automatic by means of a spring mechanism. recovery that is activated by overriding the blocking device.

The basic elements of the invention are the following:

the briefcase

the connection cable

The braking/unlocking device

recovery device

A compartment for small parts (Schuko converter)

Fastening means

Illuminated control screen with LED diodes, with charge indicator and cut-off relay due to overload or heating.

- Reserved area for brand and logo

The briefcase is the container intended to carry the cable with all the installation and operating accessories. It has a shape reminiscent of the boxes that are used to carry snow chains, although it is designed for this new purpose, having a handle that facilitates its portability and magnetic means that allow it to be placed on all types of bodies, both ferromagnetic and those that they are not. It has an area for the brand and its logo.

The charging cable is one of the basic elements of the invention, although not in terms of its constitution but in the way of storing it inside the casing, in the way of carrying out its extraction, locking in the working position and return to the stored position. In principle it is a three-phase cable that is incorporated into the case according to several embodiments. A first mode consists of a smooth stretch that can be unrolled and a curly stretch that is extensible and unrolled. A second mode is equipped with all-smooth wire and the third, also all-smooth wire, is case-mounted with two spools having a sliding interconnection of rings and brushes. In all cases, different connectors can be mounted depending on the type of vehicle and the bases of the charging post. It is taken into account that the usual connectors, in the most modern vehicles, are those known as Type 2, which are three-phase with neutral and three auxiliary conductors, that is, a total of seven conductors. This cable is complemented by a Schuko converter for use in public or private garages.

The equipment also incorporates a screen equipped with LED lighting, which has a charge indicator and an automatic overload switch. In the drawings included in the document, as an inseparable part thereof, the consistency of the invention is schematically shown.

Briefcase with charging cable for electric cars and other vehicles (1) (Figs. 1 to 8) which refers to a special, portable briefcase that contains a connection cable of those necessary to recharge electric vehicle batteries. In an embodiment preferred by its inventors, it comprises a briefcase (1), reminiscent of those used to store snow chains, whose front, rear, right and left side views are represented in Figures 1 to 4. Manufactured in polyethylene to be able to be used outdoors in the worst weather conditions. It has a handle (8) for handling it, having several neodymium magnets (10) on its back, which allow the briefcase (1) to be fixed to the body of a car, either on the roof, on the side, on the trunk lid or on the trunk, in the case of vehicles with bodywork made of ferromagnetic material. For other types of bodies or nautical hulls made of fiberglass, aluminum or any other non-ferromagnetic material, there is an auxiliary plate (13), which once placed and adhered in the place chosen by the user, also facilitates placement. of the briefcase For example, in the case of a car, the auxiliary plate can be placed on one of the side windows, on the rear window or at the bottom of the trunk and secure the briefcase (1) on it, since the magnets are of great power of attraction, they can exert their force through the thickness of glass or a sheet of plastic, aluminum or fiberglass. In all cases, the magnets (10) are equipped with felts (11) that prevent possible damage to paint, glass and delicate surfaces.

For those occasions when circumstances so advise and for smaller vehicles such as scooters, bicycles, etc., the briefcase (1) is equipped with a removable leg (12), in the lower rear part, which allows it to be positioned on the ground or any substantially horizontal surface.

Figure 5 schematizes a first embodiment that shows the inside of the case (1) where the connection cable is installed wound on a reel (15), rotating in one direction, when the cable is pulled subjecting the spring (16) to its elastic deformation and in the opposite direction when the cable is stored, releasing the elastic energy stored in the spring (16), once the user acts on the release button (4) existing on the front of the case. The cable is automatically locked in any position reached after being pulled. In this first embodiment, there is a smooth cable (2), about four meters long, which is attached to the anchor (14), integral with the reel (15). One of the ends of the cable, after a series of winding turns on the reel, goes outside where a connector (3) is installed, one of those that is convenient for the user in each case, depending on the type of vehicle.

The other part of the smooth cable (2) is also rolled up on the drum (15) in parallel to the first part mentioned above, reaching a moment when, near its exit to the outside, it turns from a smooth cable (2) to spirally curly extendable cable (2.1). This extensible cable (2.1), although short when at rest, allows an elongation of up to approximately one meter, resulting in a total available cable length of about five meters. At the outlet of the briefcase (1) of this extensible cable (2.1) another connector (3) of the type that suits the user according to the vehicle available is installed.

In figure 5 it can be seen that both ends of the cable, in the vicinity of the connectors (3) are joined by means of a stud (17). With this arrangement, when you want to proceed with loading the vehicle and once the case (1) is placed in the chosen place, it is necessary to pull both ends without removing the prisoner (17), until the entire section of the extensible cable is (2.1) remains on the outside of the case. If the lengths of the smooth cable (2) and extendable cable (2.1) are sufficient to reach the charging bases in the vehicle and on the fixed pole, the stud (17) can be removed and connection and charging can proceed. If not, continue to pull both cables until the required cable length is reached.

Figure 6 shows a second embodiment in which the entire section is smooth cable (2). If the cable is followed from one of the connectors (3) to the inside of the briefcase (1), it can be seen that it remains coiled on the reel (15) turning several times until it reaches the anchor (14) where it hooks and begins to retract. on the reel (15), giving the same number of turns, until its exit to the outside and arrival at the second connector (3). In this case, to remove the cable before starting to recharge the vehicle, as there is no extensible cable section, it is sufficient to pull both ends at the same time until the desired cable length is achieved, the prisoner (17) not being necessary. .

Figures 7 and 8 schematize the most important aspects of a third embodiment, which consists of installing two almost identical reels in the same case (1). which have been called reel A (15.1) and reel B (15.2) on which two individual smooth cables (2) of equal or different length are wound. The two reels rotate on the common axis (19) and move independently, therefore each one requires its braking/unlocking device and its recovery spring (16).

In this case, it is necessary to establish a special cable interconnection device, which is the one represented, (for better understanding), in an open manner, in figure 7, in which it can be seen that the near faces of the reels are equipped with a set of concentric flat rings (18) on spool A (15.1) and the same number of brushed rings (18.1) on spool B (15.2).

Having put seven rings responds to the fact that the standard connectors in modern electric vehicles are known as Type 2 (Mennekes IEC-62196-2) that have seven terminals (four for three-phase with neutral and three for control). However, the solution is valid for Type 1 (SAE J1772) connectors that only have five terminals.

It is clear that the charging cable must present continuity from the connector at one end to the connector at the opposite end, but since it is divided into two sections, which are wound on different reels A (15.1) and B (15.2), it is necessary that there is an interconnection device that electrically links each conductor of a cable with its corresponding conductor of the other cable. That is what the device in figure 7 solves permanently, regardless of the relative position of both reels, with the advantage that the cable lengths that are extracted from the case can be different and it is even possible to output each wire on opposite sides.

Figure 8 shows both reels in side view, indicating the interconnection plane (20) where the flat rings (18) and the rings with brushes (18.1) are in permanent contact, giving continuity to the cables of both reels. The four power rings (three-phase current) have been represented with greater width in Figure 7 to imply that the currents during the battery recharging process are very strong, since they exceed 30 amps.

The briefcase (1) of the invention, on its front, figures 1 and 2, has an area (1.1) reserved for gluing or engraving the brand and logo, being equipped with LED lighting (7) for better vision. of that area and a control screen that includes a load indicator instrument (5) and a power switch. overload (6). In addition, on one of its sides it has an accessory box with a lid (9) where at least one Schuko-type converter is stored that allows recharging in the usual socket outlets of private homes or community garages.

All the proposed embodiments have protection against water of the IP-66 type, which makes it suitable for all types of weather conditions outside.

It is not considered necessary to make the content of this description more extensive so that an expert in the field can understand the scope and advantages derived from the invention, as well as develop and put into practice its object. However, it must be understood that the invention has been described according to its preferred embodiments, and modifications may be made without affecting or implying any alteration of the foundation of said invention. In other words, the terms in which this description of the invention has been exposed must always be taken broadly and not limitingly.
