Description

Technical Field

[0001] The utility model relates to the technical field of energy storage power supplies, in particular to an electric motorcycle battery with a display screen. Background Art

[0002] With the increasing environmental pollution and energy crisis, electric motorcycles, as a clean and environmentally friendly means of transportation, have been more and more widely used. As the core component of an electric motorcycle, the performance and safety of its battery are crucial.

[0003] Currently, electric motorcycle batteries usually have an interface module for connecting external devices such as chargers and motor controllers. However, in the prior art, the plug of the interface module often protrudes from the battery housing after connection, making it vulnerable to external collisions or squeezes, resulting in damage to the plug or the interface module, affecting the normal use of the battery, and even causing safety accidents.

[0004] In the prior art, the interface module of an electric motorcycle battery is set on the side or top of the battery. After connecting the plug, the plug will significantly protrude from the battery housing, making it vulnerable to the impact of road bumps or accidental collisions during riding, resulting in the plug being bent or broken, and even causing problems such as the interface module being loose or water entering.

[0005] Therefore, it is necessary to improve the existing electric motorcycle battery to overcome the defects of the prior art. Content of the Utility Model

[0006] To overcome the problems existing in the related art, the purpose of the utility model is to provide an electric motorcycle battery with a display screen to solve the problem that the plug protrudes from the battery housing in the prior art and is easily damaged.

[0007] An electric motorcycle battery with a display screen, comprising:

[0008] A box body, and a bending area formed by inward bending on one side of the box body;

[0009] An interface module, which is arranged in the bending area and used for connecting external devices;

[0010] A battery component, which is arranged in the box body and used for storing electric energy;

[0011] A control board, which is arranged in the box body and electrically connected to the interface module and the battery component.

[0012] The interface module is arranged in the bending area formed by the inward bending of the box body, effectively avoiding the interface module and its connecting plugs protruding outside the battery box body, thus preventing damage to the interface module caused by external collision or extrusion, improving the impact resistance and service life of the battery, and enhancing the safety of the battery at the same time.

[0013] Preferably, the battery assembly includes a main support frame and a sub-support frame, and both the main support frame and the sub-support frame are rectangular parallelepipeds;

[0014] Adopting the main and sub-support frame structures and configuring the battery cell modules with different capacities according to the capacity requirements can make more flexible use of the internal space of the battery box body, improving the space utilization rate and battery capacity of the battery.

[0015] Preferably, the battery assembly further includes a first battery cell module arranged in the main support frame and a second battery cell module arranged in the sub-support frame. The capacity of the second battery cell module is smaller than that of the first battery cell module, and the control board is fixed on the sub-support frame.

[0016] Arranging the first battery cell module and the second battery cell module in the main support frame and the sub-support frame respectively can effectively disperse the heat of the battery, avoiding heat accumulation. At the same time, fixing the control board on the sub-support frame with a smaller battery capacity can effectively reduce the working temperature of the control board and prevent the control board from overheating.

[0017] Preferably, the bending area is bent inward along the direction perpendicular to the long side and the wide side of the box body, and the interface module is arranged on one side surface of the bending area.

[0018] Designing the bending area to be bent inward along the direction perpendicular to the long side and the wide side of the box body can make the most of the box body space, while ensuring that the bending area has a certain depth, providing sufficient installation space for the interface module and facilitating the installation and fixation of the interface module.

[0019] Preferably, the sub-support frame is of the same height as the main support frame, the long side of the sub-support frame is connected to the long side of the main support frame, and the long side of the sub-support frame is shorter than the long side of the main support frame.

[0020] The design that the sub-support frame is of the same height as the main support frame and their long sides are connected can ensure the structural stability of the battery assembly. At the same time, the shorter design of the sub-support frame can reserve space for the bending area, avoiding interference with the interface module and making the battery structure more compact and reasonable.

[0021] Preferably, both the main support frame and the auxiliary support frame are symmetrically provided with two layers up and down. Each layer of the main support frame is provided with one of the first battery cell modules, and each layer of the auxiliary support frame is provided with one of the second battery cell modules. The first battery cell module and the second battery cell module each include a plurality of square battery cells. Connection terminals are provided on both sides of the top surface of the square battery cells. The top surfaces of the two layers of square battery cells are arranged back to back, and a separation layer is provided between the two layers of square battery cells.

[0022] Adopting a structure with upper and lower layers and the battery cells arranged back to back can effectively improve the space utilization rate of the battery and increase the battery capacity. At the same time, the connection terminals are arranged on the top surface of the square battery cells, which is convenient for the series and parallel connection between the battery cells and facilitates the assembly and maintenance of the battery pack. A separation layer is provided between the two layers of battery cells, which can enhance the heat dissipation performance of the battery and improve the safety of the battery.

[0023] Preferably, both the main support frame and the auxiliary support frame include side guard plates and fences. Each layer of the main support frame and the auxiliary support frame includes four side guard plates, and the four side guard plates are connected to each other in pairs. The fences are provided at the upper and lower ends of the main support frame and the auxiliary support frame, and the fences are arranged between the two connection terminals of the square battery cells.

[0024] The design of the side guard plates and fences can effectively fix the battery cells on the support frame, enhance the mechanical strength of the battery assembly, and improve the anti-vibration and anti-impact capabilities of the battery. At the same time, the design of the fences can prevent the battery cells from shifting or falling off due to vibration, ensuring the safe and stable operation of the battery.

[0025] Preferably, the first battery cell module includes 8 pieces of the square battery cells, and the 8 square battery cells are arranged in parallel along the length direction of the first battery cell module. The second battery cell module includes 2 pieces of the square battery cells, and the 2 square battery cells are arranged in parallel along the width direction of the second battery cell module.

[0026] According to the size differences between the main and auxiliary support frames, reasonably planning the number and arrangement of the battery cells in the first and second battery cell modules can maximize the utilization of the space of the support frame and improve the energy density of the battery.

[0027] Preferably, a display module is further provided on the box body. The display module is used to display the battery status information. The display module is provided on the front surface of the box body. The display module is electrically connected to the control board. The bending area is bent inward at a right angle along the high edge of the front surface of the box body, and the interface module is arranged parallel to the display module.

[0028] Setting the display module on the front surface of the box body can facilitate the user to view the status information such as the battery power, voltage, and temperature in real time, improving the user experience. The layout design of the bending area and the interface module can avoid interference with the display module and ensure the normal operation of each component.

[0029] Preferably, along the front-to-back direction of the box body, the control board, the auxiliary support frame, and the main support frame are arranged in parallel in sequence. The auxiliary support frame is away from the bending area, and the auxiliary support frame and the main support frame form an avoidance area, which is correspondingly arranged with the bending area.

[0030] A reasonable internal layout design can make full use of the space of the box body and improve the space utilization rate of the battery. The setting of the avoidance area can prevent the bending area from interfering with the battery assembly, ensure the compactness of the battery structure, and is also beneficial to the heat dissipation of the battery.

[0031] Preferably, along the bottom-to-top direction of the box body, the interface module includes a power input interface, a power output interface, and an output control switch, and the power input interface, the power output interface, and the output control switch are respectively electrically connected to the control board.

[0032] Concentrating the functional interfaces and control switches of the interface module and electrically connecting them to the control board can effectively control and manage the charging and discharging process of the battery, improving the safety and service life of the battery.

[0033] The beneficial effects of the present utility model are as follows:

[0034] The present utility model provides an electric motorcycle battery with a display screen. By arranging the interface module in the bending area formed by bending one side of the box body inward, the problem that the interface module protrudes outside the battery box body is solved structurally. The bending area provides a physical barrier for the interface module. Even if there is a collision or extrusion, the external force will first act on the external structure of the bending area rather than the interface module itself. Thus, damage to the interface module caused by external collision or extrusion is avoided, the impact resistance and service life of the battery are improved, and the safety of the battery is also enhanced.
