La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a una carcasa para batería eléctrica que aporta, a la función a que se destina, ventajas y características, que se describen en detalle más adelante. The invention, as expressed in the statement of the present descriptive memory, refers to a casing for an electric battery that provides, to the function for which it is intended, advantages and characteristics, which are described in detail below.

El objeto de la presente invención recae en una carcasa para batería eléctrica, en particular una batería eléctrica, por ejemplo para motocicletas o vehículos eléctricos similares, de las conformadas por una caja metálica que aloja una pluralidad de celdas electroquímicas que, convenientemente conectadas, convierten los elementos químicos que almacenan en corriente eléctrica, la cual se distingue esencialmente por el hecho de comprender una pieza de sujeción superior que, dimensionada para encajar sobre la pared perimetral de la mencionada caja en forma de recipiente de la carcasa, sirve para la sujeción y el centrado de las celdas así como para la insulación de las mismas, para lo cual presenta unos alojamientos con orificios, preferentemente circulares al igual que las celdas, que rodean la base superior de cada celda y que solo dejan al descubierto los contactos de las mismas necesarios para la conexión eléctrica. The object of the present invention falls on a casing for an electric battery, in particular an electric battery, for example for motorcycles or similar electric vehicles, of those made up of a metallic box that houses a plurality of electrochemical cells that, conveniently connected, convert the chemical elements that store electrical current, which is essentially distinguished by the fact that it comprises an upper fastening piece that, dimensioned to fit on the perimeter wall of said box in the form of a container of the casing, serves for fastening and centering of the cells as well as for their insulation, for which it presents housings with holes, preferably circular like the cells, which surround the upper base of each cell and only expose the necessary contacts of the cells for electrical connection.

CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION

El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de baterías eléctricas, centrándose particularmente en el ámbito de las baterías eléctricas celulares. The field of application of the present invention falls within the sector of the industry dedicated to the manufacture of electric batteries, focusing particularly on the field of cellular electric batteries.

ANTECEDENTES DE LA INVENCIÓN Son conocidas en el mercado baterías eléctricas celulares del tipo que aquí concierne, es decir, conformadas por una carcasa que interiormente aloja una pluralidad de celdas electroquímicas conectadas para producir corriente eléctrica cuyo número de celdas es irrelevante. Por ejemplo, para el caso de las baterías destinadas a motocicletas eléctricas, el número de celdas puede rondar las 200. BACKGROUND OF THE INVENTION Cellular electric batteries of the type concerned here are known on the market, that is to say, made up of a casing that internally houses a plurality of electrochemical cells connected to produce electric current whose number of cells is irrelevant. For example, in the case of batteries for electric motorcycles, the number of cells can be around 200.

Este tipo de baterías, para que su funcionamiento sea óptimo, deben disipar correctamente el calor generado por las celdas. Actualmente la disipación del calor generado por las celdas se realiza mediante conducción radial puesto que en la cara superior e inferior de las celdas existen las conexiones que dificultan la refrigeración por el eje axial. For these types of batteries to function optimally, they must correctly dissipate the heat generated by the cells. Currently the dissipation of the heat generated by the cells is carried out by means of radial conduction since on the upper and lower face of the cells there are connections that make cooling by the axial axis difficult.

Adicionalmente, las baterías deben tener todas las celdas correctamente colocadas para que posteriormente se puedan efectuar los arcos de conexión, por ejemplo, mediante un robot computerizado. Actualmente la correcta colocación de las celdas se realiza mediante un elemento que fija las celdas entre sí por el área central de las celdas dejando libre sus extremos (cara superior e inferior) para su conexión. Additionally, the batteries must have all the cells correctly positioned so that the connection arcs can be made later, for example, by means of a computerized robot. Currently, the correct placement of the cells is done by means of an element that fixes the cells to each other through the central area of the cells, leaving their ends (upper and lower face) free for their connection.

El objetivo de la presente invención es, pues, proporcionar una carcasa especialmente diseñada para mejorar la transferencia de calor de la celda al exterior así como un medio para facilitar la sujeción y colocación correcta de las celdas posterior conexión. The objective of the present invention is, therefore, to provide a casing specially designed to improve the transfer of heat from the cell to the outside, as well as a means to facilitate the fastening and correct placement of the subsequent connection cells.

Por otra parte, y como referencia al estado actual de la técnica, al menos por parte del solicitante, se desconoce la existencia de ninguna otra carcasa para batería eléctrica que presente unas características técnicas y estructurales ¡guales o semejantes a las que presenta la que aquí se reivindica. On the other hand, and as a reference to the current state of the art, at least by the applicant, the existence of any other casing for an electric battery that presents the same or similar technical and structural characteristics to those presented here is unknown. is claimed.

EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION

La carcasa para batería eléctrica que la invención propone se configura como la solución idónea al objetivo anteriormente señalado, estando los detalles caracterizadores que lo hacen posible y que la distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción. The casing for an electric battery that the invention proposes is configured as the ideal solution to the aforementioned objective, the details being characterizations that make it possible and that distinguish it conveniently included in the final claims that accompany this description.

Concretamente, lo que la invención propone, como se ha apuntado anteriormente, es una carcasa para batería eléctrica, en particular una batería eléctrica, por ejemplo para motocicletas o vehículos eléctricos similares, de las constituidas por una caja metálica que aloja una pluralidad de celdas electroquímicas o pilas idénticas, la cual se distingue esencialmente por el hecho de comprender una pieza de sujeción superior que, dimensionada para encajar sobre la pared perimetral de la mencionada caja en forma de recipiente de la carcasa, sirve para la sujeción y el centrado de las celdas así como para la insulación de las mismas, para lo cual presenta unos alojamientos provisto de orificios, preferentemente circulares al igual que las celdas, que rodean la base superior de cada celda y que solo dejan al descubierto los contactos de las mismas necesarios para la conexión eléctrica. Specifically, what the invention proposes, as previously noted, is a casing for an electric battery, in particular an electric battery, for example for motorcycles or similar electric vehicles, of those made up of a metal box that houses a plurality of electrochemical cells. or identical batteries, which is essentially distinguished by the fact that it comprises an upper fastening piece that, dimensioned to fit on the perimeter wall of the aforementioned box in the form of a container of the casing, serves for the fastening and centering of the cells. as well as for their insulation, for which it presents housings provided with holes, preferably circular like the cells, which surround the upper base of each cell and only expose the contacts necessary for the connection. electrical.

Esta pieza de fijación superior, que se une peñmetralmente a la caja de la carcasa, sirve para centrar las celdas por su parte superior de manera que todas las celdas quedan perfectamente paralelas entre sí con la misma separación, así como para cerrar la estructura que aguanta las celdas y para aislar el polo positivo del negativo y solo dejar a la vista o accesible una parte para su conexionado. This upper fixing piece, which is attached to the perimeter of the casing box, is used to center the cells on the upper part so that all the cells are perfectly parallel to each other with the same spacing, as well as to close the structure that supports cells and to isolate the positive pole from the negative pole and only leave a part visible or accessible for its connection.

Para ello, preferentemente, cada alojamiento circular de la pieza de fijación superior presenta un orificio central, en coincidencia con el tetón de la base superior de las celdas, que constituye el polo positivo o ánodo de las mismas, y un orificio lateral, previsto en la superficie circular existente entre dicho orificio central y la pared perimetral de la hendidura, que deja a la vista al menos una porción del borde perimetral de cada celda y que constituye el polo negativo o cátodo. To do this, preferably, each circular housing of the upper fixing piece has a central hole, coinciding with the lug on the upper base of the cells, which constitutes the positive pole or anode thereof, and a lateral hole, provided in the circular surface existing between said central hole and the perimeter wall of the slit, which exposes at least a portion of the perimeter edge of each cell and which constitutes the negative or cathode pole.

Además, en el modo de realización preferido de la invención, la pieza de sujeción superior de la carcasa presenta asimismo unos conos que emergen alrededor de los antedichos alojamientos circulares y que actúan a modo de dedos guía para ayudar al centrado conjunto de todas las celdas en su correcta posición. Al haber un gran número de celdas (200 aproximadamente) su centrado individual es muy difícil, por lo que preferentemente se necesita de dicho elemento centrador para facilitar el centrado de todas en conjunto. In addition, in the preferred embodiment of the invention, the upper fastening part of the casing also has cones that emerge around the aforementioned circular housings and that act as guide fingers to help to the joint centering of all the cells in their correct position. As there are a large number of cells (approximately 200) their individual centering is very difficult, so said centering element is preferably needed to facilitate the centering of all of them together.
