Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electric motorcycles, and particularly relates to a cross-sitting motorcycle structure with an extended seat cushion. BACKGROUND

[0002] As an important carrier of transportation and leisure, the cross-sitting vehicle gradually exposes the limitations of traditional design in the process of electrification. The early seat cushion design of the cross-sitting electric motorcycle focuses on single commuting, and generally has problems such as insufficient length (usually only suitable for single riding), single structure (mostly flat and thin design), and lack of support. And the existing cross-sitting electric motorcycle has a whole seat cushion design, which has poor comfort. When opening, the whole seat cushion is usually opened, the opening angle is large, and it is very troublesome. For electric motorcycles, the battery is the core. The demand for long endurance and high-rate charging and discharging of the battery is increasingly urgent. The increase in power density of the battery cell leads to a significant increase in heat generation per unit volume. Traditional batteries mainly use two cooling methods: one is natural cooling, which conducts heat from the battery cell to the metal shell through a heat-conducting silica gel sheet, and the cooling efficiency is very low, which cannot cope with the concentrated heat generation during high-rate charging and discharging, and is prone to battery thermal runaway. The second is air cooling, which uses an external fan to force air circulation. However, in the compact power group space of the cross-sitting electric motorcycle, air circulation is limited, and the fan is noisy and prone to dust accumulation, with poor cooling uniformity, making it difficult to control the temperature difference of the battery cell within a safe range (usually requiring a temperature difference of less than 5°C). Both of these technologies have a chain problem of "insufficient cooling capacity - battery life decay - increased safety risk". Data shows that the cycle life of the battery under traditional cooling methods is only 500-800 times, and the endurance capacity decays by 15%-20% per year.

[0003] Therefore, the existing structure and deficiencies are researched and improved, and a cross-sitting electric motorcycle structure with an extended seat cushion is provided to achieve a more practical purpose. SUMMARY

[0015] Compared with the prior art, the application has the following technical effects: At present, the seat cushion of the straddle car is designed in an integral mode, and the application adopts the mode of the first sub-cushion and the second sub-cushion, and divides the seat cushion into two sections, which is a structural innovation, wherein the first sub-cushion can be set in different shapes according to requirements, the battery is installed from the lower part of the seat cushion, which is different from the traditional side or top installation, and has novelty, the front and rear separated seat cushions can improve the riding comfort, and the lower battery installation is convenient for maintenance.

[0016] The design of the cooling pipe in a capillary shape can better take out the heat inside the battery, improve the cooling effect, and the design of the first heat exchange pipe and the second heat exchange pipe can perform two different modes of cooling. When the temperature inside the battery is not high, the liquid in the cooling pipe passes through the first heat exchange pipe, and the heat dissipation holes at both ends of the cooling cavity can make the airflow pass through the cooling cavity, which can take away the temperature on the surface of the first heat exchange pipe through air cooling, realizing air cooling cooling. When the temperature inside the battery is too high, the conventional air cooling cannot take away the heat, at this time, the cooling pipe is communicated with the second heat exchange pipe, and the semiconductor sheet is powered on. After the semiconductor is powered on, the cooling plate can be refrigerated and cooled. Through the refrigeration cooling mode, the liquid in the cooling pipe can be cooled more efficiently, so that the battery inside can be cooled more quickly. At this time, the heat generated by the heat dissipation plate can be taken away by the flowing airflow. When the battery encounters a power failure in extremely cold weather, artificial preheating of the battery cannot be performed more quickly. At this time, the heat dissipation plate moves towards the first heat exchange pipe, and the heat dissipation fins rotate from a horizontal shape to a vertical shape, so that the first heat exchange pipe is located in the first placement groove, and the heat dissipation fins are attached to the inner wall of the cooling cavity. At the same time, the bottom baffle seals the heat dissipation fins, and the heat dissipation fins form a self-heating particle storage space. In this way, the self-heating particles in the storage box are introduced into the heat dissipation fins, and the self-heating particles can generate heat to heat the liquid in the first heat exchange pipe. The heated liquid enters the cooling pipe, and through the capillary-shaped pipeline, the battery can be preheated more quickly and efficiently, so that the battery can be restored to use more quickly. The vertical design of the heat dissipation fins can effectively prevent airflow from entering the heat dissipation fins, ensuring the temperature of the self-heating particles. The rotatable design of the heat dissipation plate can ensure that when heat dissipation is needed, the heat dissipation fins are horizontal, the airflow direction is consistent, and the heat on the heat dissipation fins can be taken away more efficiently. When heat preservation is needed, the vertical design of the heat dissipation fins can prevent a large amount of cold airflow from entering, and can also form a storage cavity.

[0050] Please refer to Figure 9In the embodiment, the semiconductor sheet 377 is electrically connected to the motor connection end of the heat dissipation fan 36 through a wire. The design that the semiconductor sheet 377 is electrically connected to the driving motor of the heat dissipation fan 36 can heat the heat dissipation plate 37 when the self-heating particles heat the first heat exchange pipe 331 in extremely cold weather. In this way, the heat dissipation plate 37 generates high temperature, and the temperature at the end of the cooling plate 38 is far lower than that of the heat dissipation plate 37, so that the temperature difference between the two ends of the semiconductor sheet 377 is generated.

The rotation of the heat dissipation fan 36 can make the airflow flow, so as to ensure that the temperature at the end of the cooling plate 38 is always in a low state, so as to maintain the temperature difference. At the same time, since the heat dissipation fins 371 are rotated to be vertical, the airflow cannot pass through the heat dissipation fins 371, so that the self-heating particles can heat more fully.

[0051] Please refer to Figure 14 In the embodiment, one end of the baffle 39 is provided with a rotatingly connected first shaft 391, the first shaft 391 is rotatingly connected to the inner wall of the cooling cavity 31, and a torsion spring for driving the baffle 39 to automatically rotate to be horizontal is arranged on the first shaft 391. The other end of the baffle 39 is provided with a penetrating hole 392, the penetrating hole 392 is provided with a slidingly connected second shaft 393, a reset groove 394 is arranged on the inner wall of the penetrating hole 392, a reset block 396 is arranged in the reset groove 394, the reset block 396 is fixedly connected to the second shaft 393, a reset spring 395 for driving the reset block 396 to automatically return to the initial position is arranged in the reset groove 394, and a limiting hole for automatically inserting the second shaft 393 when the baffle 39 is horizontal is arranged on the inner wall of the cooling cavity 31.

[0052] The design of the first shaft 391 and the torsion spring can automatically rotate the baffle 39 to be horizontal without external force. The design of the second shaft 393 and the reset spring 395 can make the second shaft 393 be pushed out by the reset spring 395 without external extrusion, so that the second shaft 393 cannot be inserted into the limiting hole. When the heat dissipation plate 37 moves towards the baffle 39, the second shaft 393 can be extruded, so that the second shaft 393 can be inserted into the limiting hole, and the baffle 39 can be automatically fixed, so as to ensure the stability of the baffle 39 in use. When the heat dissipation plate 37 is separated, the reset spring 395 can drive the second shaft 393 to separate from the limiting hole. In this way, the self-heating particles on the baffle 39 can extrude the baffle 39 to automatically rotate and incline, so that the self-heating particles can automatically fall. After the self-heating particles fall, the baffle 39 can be automatically kept horizontal through the action of the torsion spring.

[0053] Please refer to Figure 8 In the embodiment, the cooling cavity 31 is provided with a plurality of fixedly connected and retractable positioning rods 381, the ends of the positioning rods 381 are fixedly connected with the cooling plate 38.

[0054] The application is used: When the battery needs to be taken out, only the first sub-pad 21 needs to be disassembled, and the liquid-cooled battery in the accommodating cavity 3 can be seen, and the liquid-cooled battery can be taken out at this time, which is very convenient and fast; In the process of using the liquid-cooled battery, under normal circumstances, the first heat exchange pipe 331 is in communication with the cooling pipe, when the temperature inside the battery rises, the cooling fan 36 is started, the cooling fan 36 can make the air in the cooling cavity 31 flow, the flow of air can take out the heat on the first heat exchange pipe 331, so as to better reduce the temperature of the liquid in the cooling pipe, so that the temperature inside the battery can return to normal, at the same time, the rotation of the cooling fan 36 can drive the driving plate 351 to reciprocate periodically through the transmission mode, cooperate with the one-way valve 354, can make the liquid in the cooling pipe flow, can more quickly reduce the temperature inside the battery; When the temperature inside the battery is too high, the cooling fan 36 cannot cool the inside of the battery, at this time, the cooling plate 38 is controlled to move, so that the cooling plate 38 is attached to the heat preservation plate 382, at this time, the output end of the battery is electrically connected with the semiconductor sheet 377, the semiconductor sheet 377 is started, the semiconductor can make the cooling plate 38 refrigerate and cool, the second heat exchange pipe 332 can be cooled through the cooling plate 38, and at the same time, the three-way valve 333 is controlled to make the cooling pipe two ends respectively in communication with the second heat exchange pipe 332, so that the cooled cooling plate 38 can more efficiently cool the second heat exchange pipe 332, so that the temperature of the liquid in the cooling pipe is lower, thereby more efficiently cooling the inside of the battery, and the heat generated at the other end of the semiconductor sheet 377 can be taken out through the heat sink plate 37 and the heat sink fin 371, cooperate with the cooling fan 36, can take out the heat generated by the semiconductor sheet 377 in time, ensure the stable operation of the whole; When the battery is in extremely cold conditions and cannot be used due to power failure, the control heat sink 37 moves towards the first heat exchange pipe 331 at this time. With the movement of the heat sink 37, the connecting piece 387 can automatically drive the connecting shaft 386 to rotate, and the rotation of the connecting shaft 386 can drive the adjusting shaft 376 to rotate through the transmission of the first bevel gear 373 and the second bevel gear 385, thereby driving the rack to rotate through the first gear 379, so that the second plate 3702 automatically rotates, realizing the rotation of the heat dissipation fins 371. By controlling the gear ratio of the first bevel gear 373 and the second bevel gear 385, the heat dissipation fins 371 can be moved to the set position, and the first heat exchange pipe 331 can be located in the first placement slot 372 inside the heat dissipation fins 371, and the heat dissipation fins 371 are rotated from horizontal to vertical. When the heat sink 37 moves to the set position, the heat sink 37 can press the second shaft 393, so that the second shaft 393 can be inserted into the limiting hole, and the baffle 39 can be automatically fixed. At this time, the heat dissipation fins 371, the second plate 3702, the inner wall of the cooling cavity 31 and the baffle 39 form an open slot. Only the self-heating particles in the storage box 32 are automatically poured between the heat dissipation fins 371, and the self-heating particles can automatically wrap the first heat exchange pipe 331, so that the self-heating particles can automatically heat the first heat exchange pipe 331. Then electrically connect the semiconductor sheet 377 with the drive motor of the heat dissipation fan 36, so that the self-heating particles heat the first heat exchange pipe 331 at the same time, and also heat the heat dissipation fins 371, so that one end of the semiconductor sheet 377 generates high temperature, and the other end of the semiconductor sheet 377 is low temperature. The temperature difference between the two ends of the semiconductor sheet 377 can generate power through the characteristics of the semiconductor sheet 377, thereby driving the heat dissipation fan 36 to rotate, and driving the reciprocating shaft 356 to rotate through gear transmission or chain transmission, thereby realizing the periodic reciprocating movement of the adjusting plate 357, so that the drive plate 351 can realize reciprocating movement through hydraulic transmission, and cooperate with the one-way valve 354 to make the liquid in the cooling pipe flow, so that the heated liquid can automatically flow into the battery for automatic and efficient preheating. Since the heat dissipation fins 371 are rotated to vertical, and the baffle 39 is used, the airflow generated by the rotation of the heat dissipation fan 36 cannot enter the heat dissipation fins 371, so as to ensure that the heat generated by the self-heating particles in the heat dissipation fins 371 can more fully heat the first heat exchange pipe 331. However, the airflow generated by the heat dissipation fan 36 can continuously cool one end of the cooling plate 38, so as to ensure a large temperature difference and improve power generation efficiency.

[0055] When the heat dissipation plate 37 returns to the initial position, the energy stored by the leaf spring can drive the connecting shaft 386 to rotate reversely, so that the heat dissipation fins 371 can return to the initial position and automatically rotate to the horizontal state. When the heat dissipation plate 37 is separated, the reset spring 395 can drive the second shaft 393 to separate from the limiting hole, so that the self-heating particles on the baffle 39 can extrude the baffle 39 to automatically rotate and tilt, so that the self-heating particles can automatically fall off. After the self-heating particles fall off, the baffle 39 can be automatically kept in the horizontal state through the action of the torsion spring.

[0056] The design of the present application can be adjusted according to different working conditions. The wind cooling mode, liquid cooling mode and preheating mode are set, so that the storage battery can cope with various working conditions and maintain high performance.
