一种蓄电池Battery 技术领域Technical field
本发明涉及一种蓄电池。The invention relates to a battery.
背景技术Background technique
如图1所示，包括壳体1’、设于壳体1’内的蓄电元件2’、设于壳体上连通蓄电元件2’的连接柱3’、与连接柱3’相连的连接端子4’，壳体1’上设有沉孔11’，沉孔11’内填充有环氧树脂5’，所述蓄电元件2’连通有一用于添加电解液的添加柱21’，所述添加柱21’伸出壳体1’外。连接端子用于与外部的设备连接提供电能，由于在连接时往往会施加外力，这样连接端子的稳固就显得比较重要，特别其与连接柱的连接部容易受到外力的扭动而断裂，甚至会导致连接柱与蓄电元件之间的连接断裂，这样就会损坏蓄电池。现有的做法往往是在将连接端子设于连接柱上方，通过焊接的方式相连，并且在壳体上设置一个沉孔，将该焊接部置于该沉孔内，然后在沉孔内添加液态环氧树脂，冷却后形成一坚固的保护层，这种做法不仅仅能够使得连接端子与连接柱的焊接部位稳固，也能够防止连接端子晃动，还能够实现对壳体内部的密封，这样就可以比较好地保护壳体内的蓄电元件，从而提高使用寿命。但是这样一来在蓄电池内部空间的利用就会变小，这样蓄电元件也就相应变小，从而导致其容量变小，也即是其容量变小，也即是如果需要加大容量则要加大体积。As shown in FIG. 1 , the housing 1 ′, the storage element 2 ′ disposed in the housing 1 ′, the connection post 3 ′ connected to the storage element 2 ′ on the housing, and the connection post 3 ′ are connected. Connecting the terminal 4', the housing 1' is provided with a counterbore 11', the counterbore 11' is filled with an epoxy resin 5', and the storage element 2' is connected with an additional column 21' for adding an electrolyte. The addition post 21' extends beyond the housing 1'. The connecting terminal is used for connecting with an external device to provide electric energy. Since an external force is often applied during the connection, the stability of the connecting terminal is important, and in particular, the connection portion with the connecting post is easily broken by an external force, and may even be broken. This causes the connection between the connecting post and the storage element to break, which can damage the battery. In the prior art, the connecting terminals are usually arranged above the connecting post, connected by welding, and a counterbore is arranged on the casing, the welding part is placed in the counterbore, and then the liquid is added in the counterbore. The epoxy resin forms a strong protective layer after cooling. This method not only stabilizes the welded part of the connecting terminal and the connecting post, but also prevents the connecting terminal from swaying, and can also seal the inside of the housing, so that The storage element inside the housing is better protected, thereby increasing the service life. However, in this way, the utilization of the internal space of the battery becomes smaller, so that the storage element is correspondingly smaller, resulting in a smaller capacity, that is, its capacity becomes smaller, that is, if it is necessary to increase the capacity, Increase the volume.

进一步的，所述L形连接板包括上板与侧板，所述上板与侧板一体相连设置，所述上板与侧板上分别设有连接孔，所述壳体上位于L形连接板包围的部位内设有一凸块，所述上板与凸块之间或侧板与凸块之间形成可用于卡设螺母的卡置空间。Further, the L-shaped connecting plate comprises an upper plate and a side plate, wherein the upper plate is integrally connected with the side plate, and the upper plate and the side plate are respectively provided with connecting holes, and the housing is located on the L-shaped connection A bump is disposed in a portion surrounded by the plate, and a locking space for clamping the nut is formed between the upper plate and the bump or between the side plate and the bump.
进一步的，所述壳体上还设有用于添加电解液的复数个注液孔柱，所述壳体上设有一凹槽，所述各注液孔柱位于凹槽内，所述注液孔柱上可拆卸地设有安全阀胶帽，所述壳体上设有用于罩盖凹槽的盖体，所述盖体的中间开设有一通气孔，所述盖体内壁上设有一滤气片，所述滤气片覆盖通气孔。Further, the housing is further provided with a plurality of liquid injection hole columns for adding an electrolyte, the housing is provided with a groove, and the liquid injection hole columns are located in the groove, and the liquid injection hole A safety valve rubber cap is detachably disposed on the column, and the cover body is provided with a cover body for the cover groove, a vent hole is defined in the middle of the cover body, and a gas filter piece is disposed on the inner wall of the cover body.

Large, so that the capacity can be increased compared to the original battery without changing the size of the casing; further, by providing the bumps, the formation between the upper plate and the bump or between the side plates and the bumps can be used. The clamping space of the clamping nut, when it is required to be connected with the external device, the nut can be placed in the clamping space, and the connecting line of the connecting terminal and the external device is locked by bolting, and the nut is stuck Placed in the card space, it will remain motionless, so Further, the bolt is locked; further, through the cover body, and a vent hole is defined in the middle of the cover body, a gas filter sheet is disposed on the inner wall of the cover body, and the filter gas sheet covers the vent hole, and the filter gas sheet It adopts a sponge structure to make it ventilate, but it can restrict the inflow and out of airflow. Since the storage element will release hydrogen and oxygen during operation, if it is not released, it will easily cause the casing to swell or even burst. If it is released directly, when it is located, In a small space, it is easy to make the concentration reach the explosion standard and explode. Therefore, the gas filter can be set to slow down the release rate of hydrogen and oxygen, and dissipate it in the air to prevent the concentration from being too large.

本蓄电池通过改变连接端子的形状，从而改变连接端子的设置位置，从而使得壳体内部的可利用空间增大，从而使得蓄电元件的体积增大，使得在不改变壳体大小的情况下，相比原有的蓄电池能够增加容量；进一步的，通过设置凸块，从而使得上板与凸块之间或侧板与凸块之间形成可用于卡设螺母的卡置空间，当需要与外部设备连接时，可以将螺母放入卡置空间内，将利用螺栓穿设的方式锁紧连接端子与外部设备的连接线，而由于螺母是被卡置于卡置空间内，会保持不动，这样就能够方便螺栓的锁紧；进一步的，通过盖体的设置，并且盖体的中间开设有一通气孔，所述盖体内壁上设有一滤气片，所述滤气片覆盖通气孔，该滤气片采用海绵体结构使其能够通气，但是又能够限制气流的进出，由于蓄电元件在工作时会释放氢气、氧气，若不释放很容易会使得壳体胀大甚至爆裂，若直接释放，当位于狭小空间中，很容易使得浓度达到爆炸标准而发生爆炸，因此设置滤气片能够减缓氢气与氧气的释放速度，使之消散在空气之中，防止浓度过大。The battery changes the shape of the connection terminal, thereby changing the installation position of the connection terminal, thereby increasing the available space inside the housing, thereby increasing the volume of the storage element, so that the size of the housing is not changed, Compared with the original battery, the capacity can be increased; further, by providing the bumps, a space for the clamping nut can be formed between the upper plate and the bump or between the side plate and the bump, when needed and external equipment When connecting, the nut can be placed in the card space, and the connection line between the connection terminal and the external device can be locked by bolting, and since the nut is stuck in the card space, it will remain stationary. Further, the locking of the bolt can be facilitated; further, through the arrangement of the cover body, and a vent hole is defined in the middle of the cover body, a gas filter sheet is disposed on the inner wall of the cover body, and the filter gas sheet covers the vent hole, the filter The gas piece adopts a sponge structure to enable it to ventilate, but it can restrict the inflow and out of the airflow. Since the electricity storage element releases hydrogen and oxygen during operation, it is easy to release. The shell is swollen or even bursted. If it is released directly, when it is located in a small space, it is easy to make the concentration reach the explosion standard and explode. Therefore, the gas filter can slow down the release rate of hydrogen and oxygen and dissipate it in the air. To prevent excessive concentration.
尽管结合优选实施方案具体展示和介绍了本发明，但所属领域的技术人员应该明白，在不脱离所附权利要求书所限定的本发明的精神和范围内，在形式 上和细节上可以对本发明做出各种变化，均为本发明的保护范围。 Although the present invention has been particularly shown and described with respect to the preferred embodiments, those skilled in the art Various changes in the invention can be made in the above and in the details, which are the scope of the invention.
