Description

  The present invention relates to a battery assembly, and more particularly, to a battery assembly that can prevent a battery unit from arbitrarily sliding.

  Each of the current battery holder assemblies is a battery seat having a fixed structure, and is used to accommodate a plurality of battery units. However, since the structure of the battery holder assembly is constant, the number of battery units that can be accommodated is also constant, and if it is desired to increase the number of battery units, it is necessary to redesign the structure of the battery holder assembly. receive. In addition, the battery unit and the battery unit in the prior art are in direct close contact with each other in order to prevent the battery unit from sliding off. However, since the battery unit generates heat to provide current and the heat generated by the battery unit is difficult to be released, the battery unit becomes hot and the internal electrolyte or electrode material is easily vaporized. For this reason, the battery unit may cause thermal expansion. If the battery unit is in close contact with the other battery units, they are easily compressed and easily damaged. In addition, when different battery units are in direct contact with each other, a conduction state may occur due to a potential difference existing between them, and the power supply capability may be reduced.

  In view of this, there is a need for new battery assemblies that overcome the disadvantages of the prior art.

  A main object of the present invention is to provide a battery assembly having an effect of preventing the battery unit from sliding arbitrarily.

To achieve the above object, the battery assembly of the present invention includes a first frame and a plurality of battery units. The first frame has an inner wall surface, and a plurality of battery units are installed in the first frame, of which each battery unit has at least one anti-slip piece, and each battery unit contacts each other via the anti-slip piece The inner wall surface of the first frame is brought into contact with the anti-slip piece.

  In Embodiment 1 of the present invention, the battery assembly 1a includes a first frame 10a and a plurality of battery units 20, and the plurality of battery units 20 are installed in the first frame 10a. The external appearance of the battery unit 20 can be cylindrical, but the present invention does not limit the external shape of the battery unit 20. The battery unit 20 includes an upper end electrode 201, a lower end electrode 202, and at least one anti-slip piece 21. The upper end electrode 201 and the lower end electrode 202 are exposed to the outside of the first frame 10a, and conduct electric power to an external load (not shown) by electrical connection. The non-slip piece 21 can be manufactured from a plastic film or other material having a relatively high friction coefficient, and is attached to the surface of the battery unit 20. As a result, the battery unit 20 comes into contact with the anti-slip piece 21 on the other battery unit 20 via the anti-slip piece 21, thereby preventing mutual sliding between the battery units 20. At the same time, when the position of the battery unit 20 is close to the inner wall surface 11 of the first frame 10a, the battery unit 20 comes into contact with the inner wall surface 11 of the first frame 10a via the anti-slip piece 21 and increases the frictional force.

For this reason, the connection frame 30 can be fitted and fixed to the corresponding claw 41 and groove 42 on another connection frame 30 by the claw 41 and the groove 42. It should be noted that the fitting structure 40 shown in FIG. 1 is merely an example, and the present invention does not limit that different connection frames 30 cannot be fixed to each other unless the structure is the same. In addition, in order to reinforce the structural stability when the connecting frame 30 is assembled, it is possible to provide positioning protrusions 43 and positioning grooves 44 corresponding to each other on the surface where each connecting frame 30 and another connecting frame 30 come into contact. . Thereby, when assembling different connection frames 30, the positioning projections 43 and the positioning grooves 44 on the different connection frames 30 can be combined with each other to increase the strength at the time of connection. However, the present invention does not limit the provision of the positioning protrusion 43 and the positioning groove 44.
